如何从NSMutableString中删除最后一个字符

Question

Iam adding some text content to nsmutablestring in the form of dictionary format and again that every dictionary is split by ","(commos). But when getting this total string its displays (,) to string of ending. So how to remove that ","(commos) in that mutable string.

Please guide me if any one knows

Thanking in advance

Answer 1

This is how you need to remove character from NsmutableString....

NSRange range = NSMakeRange([concatedstring length]-1,1);
[concatedstring replaceCharactersInRange:range withString:@""];

Answer 2

这样做，你保持字符串的mutable属性：

[mutableString setString:[mutableString substringToIndex:[mutableString length]-1]];

Answer 3

要删除字符串的最后一个字符，您可以编写：

string = [string substringToIndex:[string length] - 1];
