获取URL中的文件名

/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]);

打印结果:
