如何在不插入空格的情况下替换NSString中的字符？

Question

我们假设我有字符串

NSString* myString  = @"Hello,";

如何在不留空格的情况下删除逗号？我试过了:

NSString* newString = [myString stringByReplacingOccurrencesOfString:@"," withString:@""];

和

NSString* newString = [myString stringByTrimmingCharactersInSet:[NSCharacterSet punctuationCharacterSet]];

但两者都留下了空间.

我刚刚运行以下测试

NSString * myString = @"Hello,";

NSString * newString = [myString stringByReplacingOccurrencesOfString:@"," withString:@""];

NSLog(@"%@xx",newString);

我得到2010-04-05 18:51:18.885 TestString[6823:a0f] Helloxx了输出.没有空间了.
