1.扩大有效 点击区域
-(BOOL)pointInside:(CGPoint)point withEvent:(UIEvent*)event {
CGRectbounds =self.bounds;
//扩大原热区直径至26，可以暴露个接口，用来设置需要扩大的半径。
CGFloatwidthDelta =600;
CGFloatheightDelta =600;
bounds =CGRectInset(bounds, -0.5* widthDelta, -0.5* heightDelta);
return CGRectContainsPoint(bounds, point);
}
2.
- (UIView *)hitTest:(CGPoint)point withEvent:(UIEvent *)event {
CGRect rectRange = CGRectInset(self.bounds, -30.0, -30.0);
if(CGRectContainsPoint(rectRange, point)) {
returnself;
}else{
returnnil;
}
return self;
}
//有效触摸 区域
- (BOOL)pointInside:(CGPoint)pointwithEvent:(UIEvent*)event {
CGFloatminx =self.startTouchView.frame.origin.x;
CGFloat maxx = CGRectGetMaxX(self.endTouchView.frame);
if(!self.isSelect) {
minx =CGRectGetMaxX(self.startTouchView.frame);
maxx =self.endTouchView.frame.origin.x;
}
returnCGRectContainsPoint([selfHitTestingBounds:self.boundsminx:minxmaxx:maxx], point);
}
- (CGRect)HitTestingBounds:(CGRect)boundsminx:(CGFloat)minxmaxx:(CGFloat)maxx {
CGRecthitTestingBounds = bounds;
hitTestingBounds.origin.x= minx;
hitTestingBounds.size.width= maxx - minx;
returnhitTestingBounds;
}
UITableView 点击事件被拦截处理
UITableView 拥有属于自己的点击事件，在将一个UITableView 的控件放在其它视图上， 并且其它视图需要添加手势进行操作的情况下，我们会发现我们点击UITableView的cell的时候， 并没有出发方法：
-(void)tableView:(UITableView*)tableView didSelectRowAtIndexPath:(NSIndexPath*)indexPath; 是直接进入到了手势的方法中。 这是由于手势的冲突引起的，解决方法是调用UIGestureRecognizer的大力方法：-(BOOL)gestureRecognizer:
//手势单击事件- (void) addTapGestureRecognizer:(void(^)(UITapGestureRecognizer* gesture))block { self.tapGestureEvent = block;
UITapGestureRecognizer* noticeRecognizer;
noticeRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(apGestureClick:)]; noticeRecognizer.numberOfTapsRequired = 1; // 单击
[noticeRecognizer setDelegate:self];
[self addGestureRecognizer:noticeRecognizer];
[self setUserInteractionEnabled:YES];
}
#pragma mark - UIGestureRecognizerDelegate
- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch
{
// 若为UITableViewCellContentView（即点击了tableViewCell），则不截获Touch事件
if ([NSStringFromClass([touch.view class]) isEqualToString:@"UITableViewCellContentView"]) {
returnNO;
}
return YES;
}
