通过双击切换全屏操作答案

【问题标题】：Toggle Fullscreen action with Double Tap通过双击切换全屏操作
【发布时间】：2013-07-10 00:11:06
【问题描述】：

正在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 ： - 顶视图容器 - 底部视图容器

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); 
                         }];

    }
}

}

【问题讨论】：

不完全确定您的意思。我的理解是，您希望能够双击并使全屏图像“返回”到其原始位置。要包括的其他一些细节是这个视图是否弹出，它正在显示什么，如果它是动态的，等等。
还有一点需要注意的是，你的第一个 elseif statement 有 condition || NO，所以它永远不会被调用，特别是因为你的 if 条件匹配 elseif 条件
你想要 topContainerView 还是只有 bottomContainerView 的效果？
没错，是的，这是我的代码中的一个小错误（否）。这里的原理是一样的 --> stackoverflow.com/questions/17506027/… 除了这不是“滑动手势”而是双击！！！
是的，当然，同样的效果！

试试这个代码：

#import "ViewController.h"

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

    CGRect initialTopContainerView;
    CGRect initialBottomContainerView;

    BOOL isFullScreen;
}

@end

@implementation ViewController

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        // Custom initialization

        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];

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

        UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(handleDoubleTap:)];
        tap.numberOfTapsRequired = 2;
        [bottomContainerView addGestureRecognizer:tap];

        UITapGestureRecognizer *tap2 = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(handleDoubleTap:)];
        tap2.numberOfTapsRequired = 2;
        [topContainerView addGestureRecognizer:tap2];

        initialTopContainerView = bottomContainerView.frame;
        initialBottomContainerView = topContainerView.frame;

        isFullScreen = false;

    }
    return self;
}

-(void)handleDoubleTap:(UITapGestureRecognizer *)sender {

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

    int heightSreen = result.height;
    int widthSreen = result.width;

    if ([[UIApplication sharedApplication] statusBarOrientation] == UIInterfaceOrientationLandscapeLeft || [[UIApplication sharedApplication] statusBarOrientation] == UIInterfaceOrientationLandscapeRight) {
        heightSreen = result.width;
        widthSreen = result.height;
    }

    if (sender.numberOfTapsRequired == 2) {

        CGRect newFrameTop;

        isFullScreen = !isFullScreen;

        if (isFullScreen) {

            if (sender.view.tag == 1) {
                newFrameTop = CGRectMake(0, 0, widthSreen, heightSreen);

                             }completion:nil];

        }else{

太棒了！！！恭喜，它完美运行！只是横向模式的错误修复（它需要重置视图大小），但我认为我可以做到这一点！谢谢
