第一次发表海报,长时间观察。
我正在使用故事板作为我目前正在处理的应用程序,并且需要更多的转换而不仅仅是前进,特别是回去。每当我使用这个segue我都要通过菜单返回时,点击下一个按钮转到另一个ViewController,会使整个应用程序崩溃!
不知道发生了什么,我在实施文件
中使用了这个#import "SlideLeftSegue.h"
@implementation SlideLeftSegue
- (void)perform{
UIView *sv = ((UIViewController *)self.sourceViewController).view;
UIView *dv = ((UIViewController *)self.destinationViewController).view;
UIWindow *window = [[[UIApplication sharedApplication] delegate] window];
dv.center = CGPointMake(sv.center.x - sv.frame.size.width, dv.center.y);
[window insertSubview:dv belowSubview:sv];
[UIView animateWithDuration:0.4
animations:^{
dv.center = CGPointMake(sv.center.x,
dv.center.y);
sv.center = CGPointMake(sv.center.x + sv.frame.size.width,
dv.center.y);
}
completion:^(BOOL finished){
[[self destinationViewController]
dismissViewControllerAnimated:NO completion:nil];
}];
}
@end
这是我的头文件
#import <UIKit/UIKit.h>
// Move to the previous screen with slide animation.
@interface SlideLeftSegue : UIStoryboardSegue
@end
我还在学习,所以如果你有任何想法发生的事情,我会在初学者阶段欣赏解释。

您可以用更少的代码实现这一目标
呈现视图控制器:
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
UIViewController *view = [storyboard instantiateViewControllerWithIdentifier:@"ViewID"];
view.modalTransitionStyle = UIModalTransitionStyleCoverVertical; // you can try the other 3 UIModalTransitionStyle too
[self presentViewController:view animated:YES completion:nil];
回去:
[self dismissViewControllerAnimated:YES completion:nil];
