布尔值的Objective-C格式化字符串吗? [英] Objective-C formatting string for boolean?

问题描述

哪种格式化程序用于布尔值?

What formatter is used for boolean values?

示例:NSLog(@" ??", BOOL_VAL);，什么是???

推荐答案

一种方法是将其转换为字符串(由于只有两种可能，所以并不难):

One way to do it is to convert to strings (since there are only two possibilities, it isn't hard):

NSLog(@" %s", BOOL_VAL ? "true" : "false");

我认为没有用于布尔值的格式说明符.

I don't think there is a format specifier for boolean values.
