寻找一种方法来实现双击可逆的“全屏”动作，但我没有成功！

更详细地说，有 2 个 UIView： - topViewContainer - bottomViewContainer

当我双击超级视图时，视图“bottomViewContainer”扩展到全屏，我再次双击，视图恢复到原来的大小。

它应该在纵向模式和横向模式下工作！

这是我到目前为止所做的：

-(void)handleDoubleTap:(UITapGestureRecognizer *)sender {
if ([[UIApplication sharedApplication] statusBarOrientation] == UIInterfaceOrientationLandscapeLeft || [[UIApplication sharedApplication] statusBarOrientation] == UIInterfaceOrientationLandscapeRight) {
    if (sender.numberOfTapsRequired == 2){

         NSLog(@"if gesture up - LS");

        [UIView animateWithDuration:0.5
                              delay:0.1
                            options:UIViewAnimationOptionBeginFromCurrentState
                         animations:^{
                             topContainerView.frame = CGRectMake(0.0, -160.0, 480.0, 244.0);
                             bottomContainerView.frame = CGRectMake(0.0, 0.0, 480.0, 300.0);}
                         completion:^(BOOL finished){
                           NSLog(@"%f,%f",bottomContainerView.frame.size.width,bottomContainerView.frame.size.height);                                   
                         }];

    } else if (sender.numberOfTapsRequired == 2) {

        NSLog(@"else if gesture down - LS");

        [UIView animateWithDuration:0.5
                              delay:0.1
                            options:UIViewAnimationOptionBeginFromCurrentState
                         animations:^{
                             topContainerView.frame = CGRectMake(0.0, -160.0, 480.0, 244.0);
                             bottomContainerView.frame = CGRectMake(0.0, 84.0, 480.0, 216.0);}
                         completion:^(BOOL finished){
                            NSLog(@"%f,%f",bottomContainerView.frame.size.width,bottomContainerView.frame.size.height); 
                         }];
    }
}
else if ([[UIApplication sharedApplication] statusBarOrientation] == UIInterfaceOrientationPortrait) {
    if (sender.numberOfTapsRequired == 2) {

        NSLog(@"if gesture down - PT");

        [UIView animateWithDuration:0.5
                          delay:0.1
                        options:UIViewAnimationOptionBeginFromCurrentState
                     animations:^{
                         topContainerView.frame = CGRectMake(0.0, 0.0, 320.0, 244.0);
                         bottomContainerView.frame = CGRectMake(0.0, 0.0, self.view.frame.size.width, 640.0);
                     }
                     completion:^(BOOL finished){
                         NSLog(@"%f,%f",bottomContainerView.frame.size.width,bottomContainerView.frame.size.height);
                     }];
     }
    else if (sender.numberOfTapsRequired == 2) {

        NSLog(@"else if gesture up - PT");

        [UIView animateWithDuration:0.5
                              delay:0.1
                            options:UIViewAnimationOptionBeginFromCurrentState
                         animations:^{
                             topContainerView.frame = CGRectMake(0.0, 0.0, 320.0, 244.0);
                             bottomContainerView.frame = CGRectMake(0.0, 244.0, self.view.frame.size.width, 216.0);
                         }
                         completion:^(BOOL finished){
                            NSLog(@"%f,%f",bottomContainerView.frame.size.width,bottomContainerView.frame.size.height); 
                         }];

    }
}

试试这个代码：

#import "ViewController.h"

@interface ViewController (){
    UIView *topContainerView;
    UIView *bottomContainerView;

    CGRect initialTopContainerView;
    CGRect initialBottomContainerView;

    BOOL isFullScreen;
}

@end

        CGSize result = [[UIScreen mainScreen] bounds].size;

        topContainerView = [[UIView alloc]initWithFrame:CGRectMake(0.0, 0.0, result.width, result.height/2)];
        topContainerView.backgroundColor = [UIColor redColor];
        topContainerView.tag = 1;
        [self.view addSubview:topContainerView];
