在这个字符串中我需要替换空格：

controller.body = [NSString stringWithFormat:@"http://maps.google.com/maps?q=%@@%@,%@", pinTitle.text, newlatLabel.text, newlogLabel.text];

Answer 1

像：

NSString *finalString = [controller.body stringByReplacingOccurrencesOfString:@" " withString: @"+"];

---

controller.body = [NSString stringWithFormat:@"http://maps.google.com/maps?q=%@@%@,%@", pinTitle.text, newlatLabel.text, newlogLabel.text];

NSString *finalString = [controller.body stringByReplacingOccurrencesOfString:@" " withString: @"+"];

controller.body = finalString;

Answer 2

认为你正在寻找这个：

  NSString *finalString = [controller.body stringByReplacingOccurrencesOfString:@" " withString:@"+"];
