iphone - stringByReplacingOccurrencesOfString 小写和大写字符串 Objective-C

Question

我该如何解决这个问题？

NSString * vendorName=@"can't event";
vendorName= [[[vendorName stringByReplacingOccurrencesOfString:@" " withString:@"%20"]    stringByReplacingOccurrencesOfString:@"'" withString:@"\\\'"] capitalizedString];

我收到的输出是Can\'T 事件

但是，我需要结果为Can\'t Event

谢谢
