How do i replace spaces with +'s in Xcode

在此字符串我需要更換空間：

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

認爲你正在尋找這樣的：

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