IOS dismissViewControllerAnimated VS popViewControllerAnimated

设置 segue identifier 选择要跳转的连线命名  

 

程序中使用方法如下：

#pragma mark - Navigation 根据场景判断

// In a storyboard-based application, you will often want to do a little preparation before navigation

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {

    

    NSLog(@"xx%@" ,[[segue identifier ] description] );

    if ([[segue identifier] isEqualToString:@"sregister"]) {

     

    }

    // Get the new view controller using [segue destinationViewController].

    // Pass the selected object to the new view controller.

}

通过连接Push方法。

 

然后用  dismissViewControllerAnimated:YES 怎么也不生效。经过后面的努力发现要用  

 有 navigation 用需要   popViewControllerAnimated

  [ self . navigationController popViewControllerAnimated : YES ]; （自学习再怎么也得要走走弯路） 

// Dismisses the view controller that was presented modally by the view controller. 只限于窗口 

//            [self dismissViewControllerAnimated:YES completion:^{

//                NSLog(@"back");//这里打个断点，点击按钮模态视图移除后会回到这里

//            }];

以上是前人们的问题。

以上是前人们的问题。

dismissViewController is used when you do not have a navigationcontroller. Most probably you are using a navigation controller, then use self.navigationController popViewController instead.

Also take note of lemax his remark: use NULL, not nill for the completionhandler

//跳转到指定的Segue

 [self performSegueWithIdentifier:@"userLogin" sender:nil];
