BOOL到的NSString [英] BOOL to NSString

问题描述

如果我有一个返回值的方法的 BOOL ，我怎么投了一个的NSString 这样我就可以打印出来的控制台？

If I have a method that returns a BOOL, how do I cast that to an NSString so I can print it out in console?

例如，我试着这样做，这是不工作：

For example, I tried doing this, which isn't working:

NSLog(@"Is Kind of NSString:", ([thing isKindOfClass:[NSString class]]) ? @"YES" : @"NO");

但我真的想真正打开返回值放入一个NSString。我知道这是一个基本数据类型，所以我不能把它的方法。我一定要单独创建一个字符串，然后使用布尔作为参数的方法上的NSString？

But I really want to actually turn the return value into an NSString. I know it's a primitive data type, so I can't call methods on it. Do I have to create a string separately and then use the Bool as a parameter in a method on NSString?

推荐答案

您需要在您的格式字符串格式化说明：

You need a formatting specifier in your format string:

NSLog(@"Is Kind of NSString: %@", ([thing isKindOfClass:[NSString class]]) ? @"YES" : @"NO");
