ios中在uiNavigationcontroller中做轉場動畫

1:了解，當創建一個UINavigationcontroller中時，當創建一個子視圖控制器壓入uiNavigationController中，其中里面的view也別加入UINavigationcontoller.view中去了

驗證代碼

-(void)viewWillDisappear:(BOOL)animated{
    [super viewWillDisappear:animated];
      [self digui:self.navigationController.view];
     NSLog(@"2.1-->%p",self.view.superview);
}

-(void)digui:(UIView *)view{
    for (UIView *child in view.subviews) {
        NSLog(@"---%p",child);
        [self digui:child];
    }
    
}

 

轉場動畫第一種方式

-(void)click{
    
    MyViewController *my=[[MyViewController alloc] init];
    [self.navigationController pushViewController:my animated:NO];
     //因為一個事件循環機制中
    CATransition *tran=[CATransition animation];
    tran.duration=0.75;
    tran.type=@"cameraIrisHollowOpen";
    tran.subtype=kCATransitionFromLeft;
    [self.navigationController.view.layer addAnimation:tran forKey:nil];
}

轉場動畫第二種方式

-(void)click{
    
    
    [UIView transitionWithView:self.navigationController.view duration:0.5 options:UIViewAnimationOptionTransitionCurlUp animations:^{
        MyViewController *my=[[MyViewController alloc] init];
        [self.navigationController pushViewController:my animated:NO];
    } completion:^(BOOL finished) {
        
    }];
    
 
 
}

轉場動畫第三種方式

-(void)click{

    [UIView beginAnimations:nil context:nil];
    [UIView setAnimationDuration:0.5];
    [UIView setAnimationTransition:UIViewAnimationTransitionCurlUp forView:self.navigationController.view  cache:YES];
    MyViewController *my=[[MyViewController alloc] init];
   [self.navigationController pushViewController:my animated:NO];
    [UIView commitAnimations];
    }
