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种操做

    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
