Ios ui按钮点击崩溃应用程序

我在

第1页上有一个按钮

当我点击按钮时，我正在执行一些动画并导航到新的页面，比如说

第2页

在

第2页

上，当我点击时，有一个取消按钮，我想返回到上一页，即

第1页

，但点击取消按钮，我的应用程序崩溃

这是我在

第1页上的示例代码：

页面CRViewController的名称

- (IBAction)ClickMe:(id)sender {
    RegistraionViewController *secondController = [[RegistraionViewController alloc] init];

    CATransition *transitionAnimation = [CATransition animation];
    [transitionAnimation setDuration:1];
    [transitionAnimation setType:@"push"];
    [transitionAnimation setSubtype:kCATransitionFromBottom];
    [transitionAnimation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionDefault]];

    [self.view.layer addAnimation:transitionAnimation forKey:kCATransitionFromBottom];
    [self.view addSubview:secondController.view];
}

第2页上的代码：页面注册ViewController的名称（单击该名称会崩溃）

试试这个：

- (IBAction)ClickMe:(id)sender {   
    RegistraionViewController *secondController = [[RegistraionViewController alloc] init];   
    [self.navigationController pushViewController:secondController animated:YES];   
}


- (IBAction) Click:(id)sender {    
   [self.navigationController popViewControllerAnimated:YES];    
}

- (IBAction)ClickMe:(id)sender {
    RegistraionViewController *secondController = [[RegistraionViewController alloc] init];

    CATransition *transitionAnimation = [CATransition animation];
    [transitionAnimation setDuration:1];
    [transitionAnimation setType:@"push"];
    [transitionAnimation setSubtype:kCATransitionFromBottom];
    [transitionAnimation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionDefault]];

    [self.navigationController.view.layer addAnimation:transitionAnimation forKey:nil];
    [self.navigationController pushViewController:secondController animated:NO]; 
}

- (IBAction)Click:(id)sender {
    CRViewController *secondController = [[CRViewController alloc] init];

    CATransition *transitionAnimation = [CATransition animation];
    [transitionAnimation setDuration:1];
    [transitionAnimation setType:@"push"];
    [transitionAnimation setSubtype:kCATransitionFromTop];
    [transitionAnimation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionDefault]];

    [self.navigationController.view.layer addAnimation:transitionAnimation forKey:nil];
    [self.navigationController popToViewController:secondController animated:NO];
}

编辑：
我很抱歉。如果您想要自定义一些UIViewController转换动画，请参见以下内容：


或者您可以尝试以下方法：

- (IBAction)ClickMe:(id)sender {   
    RegistraionViewController *secondController = [[RegistraionViewController alloc] init];   
    [self.navigationController pushViewController:secondController animated:YES];   
}


- (IBAction) Click:(id)sender {    
   [self.navigationController popViewControllerAnimated:YES];    
}

- (IBAction)ClickMe:(id)sender {
    RegistraionViewController *secondController = [[RegistraionViewController alloc] init];

    CATransition *transitionAnimation = [CATransition animation];
    [transitionAnimation setDuration:1];
    [transitionAnimation setType:@"push"];
    [transitionAnimation setSubtype:kCATransitionFromBottom];
    [transitionAnimation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionDefault]];

    [self.navigationController.view.layer addAnimation:transitionAnimation forKey:nil];
    [self.navigationController pushViewController:secondController animated:NO]; 
}

- (IBAction)Click:(id)sender {
    CRViewController *secondController = [[CRViewController alloc] init];

    CATransition *transitionAnimation = [CATransition animation];
    [transitionAnimation setDuration:1];
    [transitionAnimation setType:@"push"];
    [transitionAnimation setSubtype:kCATransitionFromTop];
    [transitionAnimation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionDefault]];

    [self.navigationController.view.layer addAnimation:transitionAnimation forKey:nil];
    [self.navigationController popToViewController:secondController animated:NO];
}

由于子视图，您的问题存在于某个地方。我已经试过你的代码了

我在我的项目中用一些动画编写了以下代码，希望对您有所帮助

CATransition *animation = [CATransition animation];
    [animation setDelegate:self];
    [animation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionLinear]];
    [animation setDuration:0.8];
    [animation setType:kCATransitionFade];
    [animation setSubtype:kCATransitionMoveIn];

    //[[self.view layer]addAnimation:animation forKey:@"fview"];

    [self.navigationController.view.layer addAnimation:animation forKey:nil];

    [self.navigationController pushViewController:yourView animated:NO];

在“动画类型”中，可以提供所需的任何动画

希望这对你有帮助。

CATransition *animation = [CATransition animation];
    [animation setDelegate:self];
    [animation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionLinear]];
    [animation setDuration:0.8];
    [animation setType:kCATransitionFade];
    [animation setSubtype:kCATransitionMoveIn];

    //[[self.view layer]addAnimation:animation forKey:@"fview"];

    [self.navigationController.view.layer addAnimation:animation forKey:nil];

    [self.navigationController pushViewController:yourView animated:NO];

- (IBAction)ClickMe:(id)sender {
    RegistraionViewController *secondController = [[RegistraionViewController alloc] init];
    CATransition *transitionAnimation = [CATransition animation];
    [transitionAnimation setDuration:1];
    [transitionAnimation setType:@"push"];
    [transitionAnimation setSubtype:kCATransitionFromBottom];
    [transitionAnimation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionDefault]];
    [self.view.layer addAnimation:transitionAnimation forKey:kCATransitionFromBottom];
    [self addChildViewController:secondController];
    [self.view addSubview:secondController.view];
}

* 将第1页上的示例代码替换为上述代码，然后进行检查

当应用程序崩溃时，是否有任何错误消息？@Krunal:显示如何创建取消按钮。不，它在我的日志中仅显示

lldb

，尝试在按钮操作中设置断点。然后逐行执行它，看看它在哪一行崩溃。@Krunal:[self.view addSubview:secondController.view]；而不是使用[self-presentViewController:secondController animated:YES]；我想要一些动画。不推和popI已经尝试了这个代码，它的工作。您应该确保控制器层次结构中有navigationController。动画出现，但动画加载后会加载相同的文件。下面是我的代码：所有文件都在您的提供项目中丢失。无法查看动画：（我现在正在我的项目中运行此代码，伙计。请检查是否在其中传递了正确的视图名称。在代码中，如果推送视图而不是子视图，则会显示动画。

RegistrationViewController*secondController=[[RegistrationViewController alloc]init]；CATTransition*animation=[CATTransition animation]；[animation setDelegate:self]；[animation SetTiming Function:[Camediatiming Function With Name:KCAMediatiming FunctionLinear]；[animation setDuration:0.8]；[animation setType:kCATransitionFade]；[animation setSubtype:kCATransitionMoveIn]；[self.navigationController.view.layer addAnimation:animation forKey:nil]；[self.navigationController pushViewController:secondController animated:NO]；

我尝试了上面的代码，动画出现，但在动画之后它加载了相同的文件。然后检查是否要将视图传递到要复制的视图。并且不要对不同视图控制器的对象使用相同的名称。
