问题描述

家伙，您好我创建一个自定义导航返回按钮，但是当我添加此code，我的背部动画不能正常工作，并与动画。为什么回去？我认为这取决于我的@selector行动吧！

   - （无效）viewDidLoad中{
    * UIButton的按钮= [UIButton的buttonWithType：UIButtonTypeCustom];
    [按钮setImage：[UIImage的imageNamed：@goback.png] forState：UIControlStateNormal];
    [按钮addTarget：自我行动：@selector（！//这里我不知道放什么东西！）forControlEvents：UIControlEventTouchUpInside];
    [按钮SETFRAME：CGRectMake（0，0，32，32）];
    self.navigationItem.leftBarButtonItem = [[的UIBarButtonItem页头] initWithCustomView：键];
}
 

解决方案

确定我创建了一个功能和正常工作：D：

   - （无效）{pushNav
[self.navigationController popViewControllerAnimated：YES];
}
 

Hi guys i create a custom navigation back button , but when i add this code , my back animation doesn't work and go back with animation .why ? i think it depends on my @selector action !

- (void)viewDidLoad {


    UIButton *button =  [UIButton buttonWithType:UIButtonTypeCustom];
    [button setImage:[UIImage imageNamed:@"goback.png"] forState:UIControlStateNormal];
    [button addTarget:self action:@selector(//HERE ! i don't know put what thing !) forControlEvents:UIControlEventTouchUpInside];
    [button setFrame:CGRectMake(0, 0, 32, 32)];
    self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:button];


}

解决方案

-(void)pushNav {
[self.navigationController popViewControllerAnimated:YES];  
}
