將變量插入NSMutableArray對象

Question

我想添加一個預定義的字符串到NSMutableArray的對象。我以爲你會使用%@，但顯然下面的代碼執行不好。謝謝你在前進

arrayData = [[NSMutableArray alloc] 
       initWithObjects:@"%@ you look tired." name, 
           @"Why do you smell so bad?", 
           @"I have to go potty!", 
           @"%@ put your pants on!" name, 
           @"Mommy!", 
           @"Daddy!", 
           @"NOOOOOO!", 
           @"When are we going to get there?", 
           @"I HATE YOU!", 
           nil];

%@是stringWithFormat:呼叫內有效。你的代碼應該是這樣的：

arrayData = [[NSMutableArray alloc] initWithObjects: 
        [NSString stringWithFormat:@"%@ you look tired.", name], 
        @"Why do you smell so bad?", 
        @"I have to go potty!", 
        [NSString stringWithFormat:@"%@ put your pants on!", name], 
        @"Mommy!", 
        @"Daddy!", 
        @"NOOOOOO!", 
        @"When are we going to get there?", 
        @"I HATE YOU!", 
        nil];
