/images/content/booking_thumbs_uk/s_kl/50000/THB_999_H54007.jpg

更改为：

Answer 1

    NSString* original=@"\\/images\\/content\\/booking_thumbs_uk\\/s_kl\\/50000\\/THB_999_H54007.jpg";
    NSString* removed=[original stringByReplacingOccurrencesOfString:@"\\" withString:@""];
    NSLog(@"%@",removed);  // shows /images/content/booking_thumbs_uk/s_kl/00000/THB_999_H2470.jpg

要非常小心，因为在“...”之间的源代码中，反斜杠具有特殊含义。为了表示诚实的反斜杠，你需要加倍，比如“\\”。

Answer 2

您可以使用newString = [oldString stringByReplacingOccurrencesOfString:@"\\" withString:@""];
