IOS中获取文件的文件名和后缀方法

   //文件路径
    NSString *path = @"/desktop/test/image.png";
   //获得纯文件名，带后缀
    NSString *fileName  = [path lastPathComponent];            //image.png
    //获得文件路径，不带后缀
    NSString *fileName1 = [path stringByDeletingPathExtension];///desktop/test/image
    //获得文件后缀
    NSString *suffix    = [path pathExtension];                //png
    
    NSLog(@"%@-%@-%@",fileName, fileName1, suffix);            //image.png-/desktop/test/image-png
