[转]iOS 从url中获取文件名以及后缀

这里有一个模拟器沙盒路径(完整路径)

NSString* index=@"/Users/junzoo/Library/Application Support/iPhone Simulator/7.0.3/Applications/63925F20-AF97-4610-AF1C-B6B4157D1D92/Documents/DownLoad/books/2013_50.zip";

对路径截取的9种操作

NSLog(@"1=%@",[index lastPathComponent]);
NSLog(@"2=%@",[index stringByDeletingLastPathComponent]);
NSLog(@"3=%@",[index pathExtension]);
NSLog(@"4=%@",[index stringByDeletingPathExtension]);
NSLog(@"5=%@",[index stringByAbbreviatingWithTildeInPath]);
NSLog(@"6=%@",[index stringByExpandingTildeInPath]);
NSLog(@"7=%@",[index stringByStandardizingPath]);
NSLog(@"8=%@",[index stringByResolvingSymlinksInPath]);
NSLog(@"9=%@",[[index lastPathComponent] stringByDeletingPathExtension]);

对应结果

1=2013_50.zip

2=/Users/junzoo/Library/Application Support/iPhone Simulator/7.0.3/Applications/63925F20-AF97-4610-AF1C-B6B4157D1D92/Documents/DownLoad/books

3=zip

4=/Users/junzoo/Library/Application Support/iPhone Simulator/7.0.3/Applications/63925F20-AF97-4610-AF1C-B6B4157D1D92/Documents/DownLoad/books/2013_50

5=~/Documents/DownLoad/books/2013_50.zip

9=2013_50
