objective-c - 有没有办法在c中的另一个#define中做一个#define？

Question

我想达到与您在stringWithFormat方法中相同的效果。

我想知道你是否可以在 my 中调用另一个常量#define？

例如[NSString stringWithFormat:@"If you enjoyed %@ would you mind please reviewing it?", appName];

我想：

#define appName @"This App"

#define myMessage @"If you enjoyed **appName** would you mind please reviewing it?"

谢谢

Answer 1

#import <Foundation/Foundation.h>

#define appName     @"This App"
#define myMessage   @"If you enjoyed " appName @" would you mind please reviewing it?"

int main( void )
{
    @autoreleasepool
    {
        NSLog( myMessage );
    }

    return 0;
}
