stringByTrimmingCharactersInSet:不删除字符串中间的字符 [英] stringByTrimmingCharactersInSet: is not removing characters in the middle of the string

问题描述

我要从字符串中删除#".

I want to remove "#" from my string.

我尝试过

 NSString *abc = [@"A#BCD#D" stringByTrimmingCharactersInSet:[NSCharacterSet characterSetWithCharactersInString:@"#"]];

但是它仍然显示字符串为"A#BCD#D"

But it still shows the string as "A#BCD#D"

有什么问题吗?

推荐答案

您可以尝试

NSString *modifiedString = [yourString stringByReplacingOccurrencesOfString:@"#" withString:@""];
