NSString*string =@"落霞与孤鹜齐飞,秋水共长天一色";

NSMutableAttributedString*mutableAttriteStr = [[NSMutableAttributedStringalloc]init];

NSAttributedString*attributeStr1= [[NSAttributedStringalloc]initWithString:[stringsubstringWithRange:NSMakeRange(0,3)]attributes:@{NSFontAttributeName :[UIFontfontWithName:@"futura"size:12],NSForegroundColorAttributeName : [UIColorredColor],NSBackgroundColorAttributeName : [UIColoryellowColor]}];

[mutableAttriteStrappendAttributedString:attributeStr2];

[mutableAttriteStrappendAttributedString:attributeStr5];

self.label1.attributedText= mutableAttriteStr;

4.NSLigatureAttributeName

连体字符是指某些连在一起的字符，它们采用单个的图元符号。0 表示没有连体字符。1

表示使用默认的连体字符。2表示使用所有连体符号。默认值为 1（注意，iOS不支持值

为 2）

// 连体艺术字，不是每个都能连起的，f和l f和i就可以，其他各位可以自己去试试

self.label2.attributedText= [[NSAttributedStringalloc]initWithString:@"flush and fily"attributes:@{NSLigatureAttributeName : [NSNumbernumberWithInt:1],NSFontAttributeName : [UIFontfontWithName:@"futura"size:30]}];

NSMutableAttributedString*mutableAttributeStr2= [[NSMutableAttributedStringalloc]init];

[mutableAttributeStr2appendAttributedString:string6];

[mutableAttributeStr2appendAttributedString:string7];

[mutableAttributeStr2appendAttributedString:string8];

self.label3.attributedText= mutableAttributeStr2;

5.NSKernAttributeName

字符间距正值间距加宽，负值间距变窄

[objc]view plain copy

NSMutableAttributedString*mutableAttributeStr2= [[NSMutableAttributedStringalloc]init];

NSAttributedString*string6= [[NSAttributedStringalloc]initWithString:@"ABCDE "attributes:@{NSKernAttributeName : [NSNumbernumberWithInt:-3],NSForegroundColorAttributeName : [UIColorredColor]}];

NSAttributedString*string7= [[NSAttributedStringalloc]initWithString:@"FGHIJ "attributes:@{NSKernAttributeName : [NSNumbernumberWithInt:0],NSForegroundColorAttributeName : [UIColoryellowColor]}];

NSAttributedString*string8= [[NSAttributedStringalloc]initWithString:@"KLMNO "attributes:@{NSKernAttributeName : @(15),NSForegroundColorAttributeName : [UIColorblueColor]}];

[mutableAttributeStr2appendAttributedString:string6];

[mutableAttributeStr2appendAttributedString:string7];

[mutableAttributeStr2appendAttributedString:string8];

self.label3.attributedText= mutableAttributeStr2;

6.NSStrikethroughStyleAttributeName 和 NSStrikethroughColorAttributeName

NSStrikethroughStyleAttributeName 设置删除线，取值为 NSNumber 对象（整数），

NSStrikethroughColorAttributeName 设置删除线颜色

枚举常量 NSUnderlineStyle中的值：

NSUnderlineStyleNone =0x00, 不设置

NSUnderlineStyleSingle =0x01, 设置单细删除线

NSUnderlineStyleThickNS_ENUM_AVAILABLE(10_0,7_0) =0x02, 设置粗单删除线

NSUnderlineStyleDoubleNS_ENUM_AVAILABLE(10_0,7_0) =0x09,双细删除线

[objc]view plain copy

NSMutableAttributedString*mutableAttributeStr3= [[NSMutableAttributedStringalloc]init];

NSAttributedString*string9= [[NSAttributedStringalloc]initWithString:@"只要998 "attributes:@{NSStrikethroughStyleAttributeName : @(NSUnderlineStyleSingle),NSStrikethroughColorAttributeName : [UIColorredColor]}];

NSAttributedString*string10= [[NSAttributedStringalloc]initWithString:@"真的998 "attributes:@{NSStrikethroughStyleAttributeName : @(NSUnderlineStyleThick),NSStrikethroughColorAttributeName : [UIColorblueColor]}];

NSAttributedString*string11= [[NSAttributedStringalloc]initWithString:@"好吧9块拿走"attributes:@{NSStrikethroughStyleAttributeName : @(NSUnderlineStyleDouble),NSStrikethroughColorAttributeName : [UIColoryellowColor]}];

[mutableAttributeStr3appendAttributedString:string9];

[mutableAttributeStr3appendAttributedString:string10];

[mutableAttributeStr3appendAttributedString:string11];

self.label4.attributedText= mutableAttributeStr3;

7.NSUnderlineStyleAttributeName 和

NSUnderlineColorAttributeName

给文字加下划线和更换下划线颜色，属性和上面的删除线都是一样用的

[objc]view plain copy

NSMutableAttributedString*mutableAttributeStr4= [[NSMutableAttributedStringalloc]init];

NSAttributedString*string12= [[NSAttributedStringalloc]initWithString:@"只要888 "attributes:@{NSUnderlineStyleAttributeName : @(NSUnderlineStyleSingle),NSUnderlineColorAttributeName : [UIColorredColor]}];

NSAttributedString*string13= [[NSAttributedStringalloc]initWithString:@"真的88 "attributes:@{NSUnderlineStyleAttributeName : @(NSUnderlineStyleThick),NSUnderlineColorAttributeName : [UIColorpurpleColor]}];

NSAttributedString*string14= [[NSAttributedStringalloc]initWithString:@"好吧8块拿走"attributes:@{NSUnderlineStyleAttributeName : @(NSUnderlineStyleDouble),NSUnderlineColorAttributeName : [UIColoryellowColor]}];

[mutableAttributeStr4appendAttributedString:string12];

[mutableAttributeStr4appendAttributedString:string13];

[mutableAttributeStr4appendAttributedString:string14];

self.label5.attributedText= mutableAttributeStr4;

8.NSStrokeWidthAttributeName 和NSStrokeColorAttributeName

设置文字描边颜色，需要和NSStrokeWidthAttributeName设置描边宽度，这样就能使文字空心.

NSStrokeWidthAttributeName 这个属性所对应的值是一个 NSNumber 对象(小数)。该值改变笔画宽度（相对于字体 size 的百分比），负值填充效果，正值中空效果，默认为 0，即不改变。正数只改变描边宽度。负数同时改变文字的描边和填充宽度。例如，对于常见的空心字，这个值通常为 3.0。

同时设置了空心的两个属性，并且 NSStrokeWidthAttributeName 属性设置为整数，文字前景色就无效果了

[objc]view plain copy

NSMutableAttributedString*mutableAttributeStr5= [[NSMutableAttributedStringalloc]init];

// 如果这个stroke的width正数的时候，字体就中空了，那么前景色就设置无效了

NSAttributedString*string15= [[NSAttributedStringalloc]initWithString:@"HELLO "attributes:@{NSStrokeWidthAttributeName : @(5),NSStrokeColorAttributeName : [UIColoryellowColor],NSFontAttributeName : [UIFontboldSystemFontOfSize:30],NSForegroundColorAttributeName : [UIColorredColor]}];

NSAttributedString*string16= [[NSAttributedStringalloc]initWithString:@"YUKD "attributes:@{NSStrokeWidthAttributeName : @(0),NSStrokeColorAttributeName : [UIColorredColor],NSFontAttributeName : [UIFontboldSystemFontOfSize:30]}];

NSAttributedString*string17= [[NSAttributedStringalloc]initWithString:@"GOOGLE"attributes:@{NSStrokeWidthAttributeName : @(-5),NSStrokeColorAttributeName : [UIColorgreenColor],NSFontAttributeName : [UIFontboldSystemFontOfSize:30],NSForegroundColorAttributeName : [UIColorlightGrayColor]}];

[mutableAttributeStr5appendAttributedString:string15];

[mutableAttributeStr5appendAttributedString:string16];

[mutableAttributeStr5appendAttributedString:string17];

self.label6.attributedText= mutableAttributeStr5;

9.NSShadowAttributeName

设置文字阴影，取值为NSShadow对象

[objc]view plain copy

// 设置阴影

NSShadow*shadow = [[NSShadowalloc]init];

shadow.shadowBlurRadius=5.0f;// 模糊度

shadow.shadowColor= [UIColorblueColor];

shadow.shadowOffset= CGSizeMake(1,5);

NSAttributedString*string20= [[NSAttributedStringalloc]initWithString:@"HELLO_HALY_璟"attributes:@{NSFontAttributeName : [UIFontboldSystemFontOfSize:30],NSForegroundColorAttributeName : [UIColorredColor],NSShadowAttributeName : shadow}];

self.label7.attributedText= string20;

10.NSTextEffectAttributeNam

NSTextEffectAttributeName //设置文本特殊效果，取值为NSString类型，目前只有一个可用效果 NSTextEffectLetterpressStyle（凸版印刷效果）

[objc]view plain copy

// 文本印刷，我也不知道是什么鬼

// 设置阴影

NSAttributedString*string21= [[NSAttributedStringalloc]initWithString:@"HELLO_HALY_璟"attributes:@{NSFontAttributeName : [UIFontboldSystemFontOfSize:30],NSForegroundColorAttributeName : [UIColorredColor],NSShadowAttributeName : shadow,NSTextEffectAttributeName : NSTextEffectLetterpressStyle}];

self.label8.attributedText= string21;

11.NSBaselineOffsetAttributeName

文字基线偏移,想要达到以下图片的效果，就要设置需要的文字偏移，正数上移，负数下

移

[objc]view plain copy

// 设置文本的基线负数向下正数向上 0不变

UIFont*bigFont = [UIFontboldSystemFontOfSize:36];

UIFont*smallFont = [UIFontboldSystemFontOfSize:bigFont.pointSize/2];

CGFloat capHeight = bigFont.pointSize- smallFont.pointSize;

NSMutableAttributedString*attributeString6= [[NSMutableAttributedStringalloc]init];

NSAttributedString*string22= [[NSAttributedStringalloc]initWithString:@"￥"attributes:@{NSFontAttributeName : smallFont,NSForegroundColorAttributeName : [UIColorblackColor],NSBaselineOffsetAttributeName : @(0)}];

NSAttributedString*string23= [[NSAttributedStringalloc]initWithString:@"9"attributes:@{NSFontAttributeName : bigFont,NSForegroundColorAttributeName : [UIColorblueColor],NSBaselineOffsetAttributeName : @(0)}];

NSAttributedString*string24= [[NSAttributedStringalloc]initWithString:@".99"attributes:@{NSFontAttributeName : smallFont,NSForegroundColorAttributeName : [UIColorblackColor],NSBaselineOffsetAttributeName : @(0)}];

NSAttributedString*string28= [[NSAttributedStringalloc]initWithString:@" 七夕大促销 "attributes:@{NSFontAttributeName : [UIFontboldSystemFontOfSize:24],NSForegroundColorAttributeName : [UIColorblackColor],NSBaselineOffsetAttributeName : @(0),NSShadowAttributeName : shadow}];

NSAttributedString*string25= [[NSAttributedStringalloc]initWithString:@"￥"attributes:@{NSFontAttributeName : smallFont,NSForegroundColorAttributeName : [UIColorblackColor],NSBaselineOffsetAttributeName : @(capHeight -5)}];

NSAttributedString*string26= [[NSAttributedStringalloc]initWithString:@"0"attributes:@{NSFontAttributeName : bigFont,NSForegroundColorAttributeName : [UIColorredColor],NSBaselineOffsetAttributeName : @(0)}];

NSAttributedString*string30= [[NSAttributedStringalloc]initWithString:@" World "attributes:@{NSFontAttributeName : [UIFontboldSystemFontOfSize:20],NSForegroundColorAttributeName : [UIColorblackColor],NSBaselineOffsetAttributeName : @(0)}];

NSAttributedString*string31= [[NSAttributedStringalloc]initWithString:@"Hello "attributes:@{NSFontAttributeName : [UIFontboldSystemFontOfSize:40],NSForegroundColorAttributeName : [UIColorblackColor],NSBaselineOffsetAttributeName : @(0)}];

NSAttributedString*string32= [[NSAttributedStringalloc]initWithString:@" World"attributes:@{NSFontAttributeName : [UIFontboldSystemFontOfSize:20],NSForegroundColorAttributeName : [UIColorblackColor],NSBaselineOffsetAttributeName : @(6)}];

NSExpansionAttributeName 设置字体的横向拉伸，取值为NSNumber （float），正值拉伸，负值压缩

14.NSVerticalGlyphFormAttributeName

NSVerticalGlyphFormAttributeName 设置文字排版方向，取值为NSNumber对象（整数），0表示横排文本，1表示竖排文本在ios中只支持0

[objc]view plain copy

// 说明：NSVerticalGlyphFormAttributeName 设置文字排版方向，取值为NSNumber对象（整数），0表示横排文本，1表示竖排文本在iOS中只支持0

//说明：NSObliquenessAttributeName 设置字体倾斜度，取值为 NSNumber（float），正值右倾，负值左倾

// NSExpansionAttributeName

// 说明：NSExpansionAttributeName 设置字体的横向拉伸，取值为NSNumber （float），正值拉伸，负值压缩

NSMutableAttributedString*mutableAttriteStr = [[NSMutableAttributedStringalloc]init];

NSAttributedString*attributeStr1= [[NSAttributedStringalloc]initWithString:@"HeHe_XiXi_mm"attributes:@{NSFontAttributeName :[UIFontboldSystemFontOfSize:30],NSForegroundColorAttributeName : [UIColorredColor],NSShadowAttributeName : shadow,NSObliquenessAttributeName : @(1),NSExpansionAttributeName : @(1),NSVerticalGlyphFormAttributeName : @(1)}];

[mutableAttriteStrappendAttributedString:attributeStr1];

self.label1.attributedText= mutableAttriteStr;

15.NSWritingDirectionAttributeName

文字书写方向取值为以下组合为例他是一个数组包含NSNumber 一般书写就是L ---R

那么我们多个需求也就是从R --- L

The values of theNSNumberobjects should be0,1,2, or3, forLRE,RLE,LRO, orRLOrespectively, and combinations ofleftToRightandrightToLeftwithNSTextWritingDirectionEmbeddingorNSTextWritingDirectionOverride

[objc]view plain copy

// 文字书写方向

// The values of the NSNumber objects should be 0, 1, 2, or 3, for LRE, RLE, LRO, or RLO respectively, and combinations of leftToRight and rightToLeft with NSTextWritingDirectionEmbedding or NSTextWritingDirectionOverride, as shown in Table 1.

// NSWritingDirectionLeftToRight | NSTextWritingDirectionEmbedding

// NSWritingDirectionRightToLeft | NSTextWritingDirectionEmbedding

// NSWritingDirectionLeftToRight | NSTextWritingDirectionOverride

// NSWritingDirectionRightToLeft | NSTextWritingDirectionOverride

NSMutableAttributedString*attributuStr2= [[NSMutableAttributedStringalloc]init];

NSAttributedString*string1= [[NSAttributedStringalloc]initWithString:@"一切皆有可能"attributes:@{NSFontAttributeName : [UIFontboldSystemFontOfSize:24],NSForegroundColorAttributeName : [UIColorredColor],NSWritingDirectionAttributeName : @[@(3)]}];

[attributuStr2appendAttributedString:string1];

self.label.attributedText= attributuStr2;

16.NSLinkAttributeName

这货有点奇葩，所以很多人用第三方例如YYLabel来做，这东西不能在UILabel和UITextField使用，只能用UITextView来进行，实现他的代理，在代理方法里面进行URL跳转

- (BOOL)textView:(UITextView*)textView shouldInteractWithURL:(NSURL*)URL inRange:(NSRange)characterRange

该方法返回YES就能打开URL，NO不做任何事情

注：

1.一定要实现UITextView的代理才能进行URL跳转

2.textView的editable属性修改为NO，在编辑时不可点击

[objc]view plain copy

// 把 NSLinkAttributeName 属性单独列出来，是因为在 UILabel 和 UITextField 中是无法使用该属性的。更准确点说是在UILabel 和 UITextField 中无法实现点击链接启动浏览器打开一个URL地址，因为在此过程中用到了一个代理函数。只能用在 UITextView 中

self.textView.delegate=self;

self.textView.scrollEnabled=NO;

self.textView.editable=NO;

self.textView.textContainer.lineFragmentPadding=0;

self.textView.textContainerInset= UIEdgeInsetsMake(0,0,0,0);

NSString*str =@" 跳转到宓珂璟的博客";

NSMutableAttributedString*attrStr = [[NSMutableAttributedStringalloc]initWithString:str];

[attrStraddAttribute:NSLinkAttributeNamevalue:[NSURLURLWithString:@"http://blog.csdn.net/deft_mkjing"]range:[strrangeOfString:@"宓珂璟的博客"]];

[attrStraddAttribute:NSFontAttributeNamevalue:[UIFontboldSystemFontOfSize:30]range:NSMakeRange(0, str.length)];

self.textView.attributedText= attrStr;

17.NSTextAttachment

设置文本附件，取值为NSTextAttachment对象常用于图文混排

[objc]view plain copy

NSString*words =@"天才";

NSMutableAttributedString*strAtt = [[NSMutableAttributedStringalloc]initWithString:wordsattributes:@{NSFontAttributeName : [UIFontboldSystemFontOfSize:25]}];

NSTextAttachment*attatch = [[NSTextAttachmentalloc]initWithData:nilofType:nil];

attatch.bounds= CGRectMake(0,0,40,30);

attatch.image= [UIImageimageNamed:@"$DCZ2WLN9RWI6JF(Q`P_(NH.jpg"];

NSTextAttachment*attatch1= [[NSTextAttachmentalloc]initWithData:nilofType:nil];

attatch1.bounds= CGRectMake(0,0,50,30);

attatch1.image= [UIImageimageNamed:@"%5T@J(4WKWSOX2~~PY0{4M0.jpg"];

NSAttributedString*string8= [NSAttributedStringattributedStringWithAttachment:attatch];

NSAttributedString*string9= [NSAttributedStringattributedStringWithAttachment:attatch1];

[strAttinsertAttributedString:string8atIndex:1];

[strAttinsertAttributedString:string9atIndex:0];

self.label3.attributedText= strAtt;

基本的就介绍到这里了，上面那些已经足够用了，而且可以任意组合出想要的图文混排，
