我是新来的，这是来自互联网的示例脚本...我用它来学习语言Objective-C和Cocoa ... ViewController.h：

答案 0 :(得分：2)
在头文件中，您已声明方法-(void)checkAnswer，而在.m文件中，您已将其声明为-(void)checkAnswer:(int)theAnswerValue。
这意味着您的.m文件正在查找不存在的方法-(void)checkAnswer，并产生Incomplete implementation警告。只需将.h文件中的声明更改为- (void)checkAnswer:(int)theAnswerValue，您就可以了。
答案 1 :(得分：1)
checkAnswer的签名在您.h和.m
中有所不同在Quiz_GameViewController.h中：
-(void)checkAnswer;
在Quiz_GameViewController.m
中-(void)checkAnswer:(int)theAnswerValue
FIX：将Quiz_GameViewController.h更改为：
- (void)checkAnswer:(int)theAnswerValue,
答案 2 :(得分：1)
在.h中查看（没有参数的方法）：
-(void)checkAnswer;
并在.m中（带有一个int参数的方法）：
-(void)checkAnswer:(int)theAnswerValue
不完整的实施表示您在.h中声明了某些内容，但未在.m中实现该内容。
