按钮动作没有响应iPhone

Question

当我按下nextButton,这是UIBarButton.然后不执行相关的操作.

UIButton *nextButton1=[UIButton buttonWithType:UIButtonTypeCustom];
[nextButton1 setBackgroundImage:[UIImage imageNamed:@"next.png"] forState:UIControlStateNormal];
[nextButton1 addTarget:self action:@selector(goToItems) forControlEvents:UIControlEventTouchUpOutside];
[nextButton1 sizeToFit];

UIBarButtonItem *nextButton=[[UIBarButtonItem alloc]initWithCustomView:nextButton1];
self.navigationItem.rightBarButtonItem=nextButton;

Answer 1

[nextButton1 addTarget:self action:@selector(goToItems) forControlEvents:UIControlEventTouchUpInside];

你过世了UIControlEventTouchUpOutside,应该是UIControlEventTouchUpInside
