如何在Xcode中用+替换空格

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

喜欢:

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;
