Ios 抓住了一个维吾尔人的行动

我的导航栏中有如下代码：

UIBarButtonItem *myButton = [[UIBarButtonItem alloc] initWithTitle:@"Next" style:UIBarButtonItemStylePlain target:self action:@selector(self)];

self.navigationItem.rightBarButtonItem = myButton;

---

当按下此按钮时，下一步要抓取什么？

您在这里设置了

@selector（self）

，犯了一个错误

您需要在此处输入您需要启动的实际功能：

UIBarButtonItem *myButton = [[UIBarButtonItem alloc] initWithTitle:@"Next" style:UIBarButtonItemStylePlain target:self action:@selector(doSomeThing)];

当然：

- (void) doSomeThing{

}

你喜欢这样吗

   UIBarButtonItem *Button=[[UIBarButtonItem alloc]initWithBarButtonSystemItem:UIBarButtonSystemItemCancel target:self action:@selector(myAction:)];
   self.navigationItem.leftBarButtonItem=Button;


 - (void)myAction:(id)sender
    {
        //do ur actions 
    }

哦，这么简单的错误，我会在它准备好的时候把它标记为正确的。哦，这么简单的错误，我会在它准备好的时候把它标记为正确的
