ios – dismissViewControllerAnimated无效

我在 IOS6上使用Storyboard.我试图回到以前的viewcontroller,但它无法正常工作.

我在这里定制了我的后门按钮.

UIButton *btnBack = [UIButton buttonWithType:UIButtonTypeCustom];
btnBack.frame = CGRectMake(0,45,35);
[btnBack setTitle:@"Back" forState:UIControlStatenormal];
[btnBack.titleLabel setFont: [UIFont fontWithName:@"Courier" size:15]];
btnBack.layer.cornerRadius=5.0;
btnBack.layer.borderWidth=2.0;
[btnBack setBackgroundColor:[UIColor colorFbBlue]];
btnBack.layer.borderColor=[UIColor colorFbBlue].CGColor;
[btnBack setTitleColor:[UIColor whiteColor] forState:UIControlStatenormal];
[btnBack addTarget:self action:@selector(Click_On_Btn_Back) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *backBarButton = [[UIBarButtonItem alloc] initWithCustomView:btnBack];

-(void)Click_On_Btn_Back{
[self dismissViewControllerAnimated:YES completion:nil];

 }

这就是我从前一个视图控制器推送segue的方式.

if([segue.identifier isEqualToString:@"segueFbShare"]){
    FbShareViewController *fbVC=[segue destinationViewController];
    fbVC.imageUrl=self.product.ImageUrl;

}

解决方法

使用UINavigationController时转到上一个UIViewController：

[self.navigationController popViewControllerAnimated:YES];

将这行代码放在Click_On_Btn_Back方法中
