大家好，我是Objective c和iOS dev的新手。现在我尝试创建一个类似"What's the word"的应用 我有按钮和地方的问题。当我第一次点击带有Letter的按钮时一切都好（[图1]，[图2]），但是第二次按钮试着去第一个地方，但它不起作用（[图3]） 。我希望每次下一次单击按下下一个按钮（或传递currentTitle）。我尝试替换按钮并仅使用currentTitle，结果是（pic 4）。 我认为（但不确定）
中的问题- （void）letterView :( LettersView *）letterView didClick：（BOOL）didClick addChar：（NSString *）addChar
但我不知道如何解决它。我很感激任何帮助。
P.S我在评论中附上所有图像。

答案 0 :(得分：0)
如果你不这样做，我建议使用一组Ui对象，比如
@property (nonatomic, retain) IBOutletCollection(UIButton) NSArray *btnCollection;
