こんにちはUIViewController、私はUIImageViewとUIImageViewを持ってSwipeGestureRecognizerいます。したがって、ユーザーが左または右にスワイプするとchange、画像が表示されUIImageViewます。これまでのところ、機能しています。UIScrollViewページングを有効にすると、画像の 1 つのサイズを使用できません。ドラッグの効果を実現し、画像UIImageViewのように次の部分UIScrollViewを表示したいと考えています。

ここに画像の説明を入力

簡単な答え:

画像ビューに 2 つのジェスチャを追加し、カウント変数を 1 つ配置し、スワイプとノーに基づいてカウント変数を切り替えます。画像の。最後に、カウントに基づいて画像を変更します。

このコードを使用すると、正常に動作し、シンプルになります。

- (void)addAnimationPresentToView:(UIView *)viewTobeAnimated
{
    CATransition *transition = [CATransition animation];
    transition.duration = 0.30;
    transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionLinear];
    [transition setValue:@"IntroSwipeIn" forKey:@"IntroAnimation"];
    transition.fillMode=kCAFillModeForwards;
    transition.type = kCATransitionPush;
    transition.subtype =kCATransitionFromRight;
    [viewTobeAnimated.layer addAnimation:transition forKey:nil];

}

- (void)addAnimationPresentToViewOut:(UIView *)viewTobeAnimated
{
    CATransition *transition = [CATransition animation];
    transition.duration = 0.30;
    transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionLinear];
    [transition setValue:@"IntroSwipeIn" forKey:@"IntroAnimation"];
    transition.fillMode=kCAFillModeForwards;
    transition.type = kCATransitionPush;
    transition.subtype =kCATransitionFromLeft;
    [viewTobeAnimated.layer addAnimation:transition forKey:nil];

}
                - (void)viewDidLoad
                {
                    [super viewDidLoad];
                    count = 0;
                    // Do any additional setup after loading the view from its nib.

メインビューにスクロールビューを追加（フレームを適切に設定）

[mainview addSubview:scr];

次のようなメソッドを記述します。

- (void)setupScrollView:(UIScrollView*)scrMain {
}

次に、viewDidLoadスクロールビューをメソッドに渡します。

 [self setupScrollView:scr];



- (void)setupScrollView:(UIScrollView*)scrMain {
    // we have 10 images here.
    // we will add all images into a scrollView & set the appropriate size.

    for (int i=1; i<=5; i++) {
        // create image
//        UIImage *image = [UIImage imageNamed:[NSString stringWithFormat:@"sti%02i.png",i]];
        UIImage *image = [UIImage imageNamed:[NSString stringWithFormat:@"sti%02i.png",i]];
        // create imageView
//        NSLog(@"===============>%d",i);
        UIImageView *imgV = [[UIImageView alloc] initWithFrame:CGRectMake((i-1)*scrMain.frame.size.width, 0, scrMain.frame.size.width, scrMain.frame.size.height)];
        // set scale to fill
        imgV.contentMode=UIViewContentModeScaleToFill;
        // set image
        [imgV setImage:image];
        // apply tag to access in future
        imgV.tag=i+1;
        // add to scrollView
        [scrMain addSubview:imgV];
    }
    // set the content size to 10 image width
    [scrMain setContentSize:CGSizeMake(scrMain.frame.size.width*5, scrMain.frame.size.height)];
    // enable timer after each 2 seconds for scrolling.
    // [NSTimer scheduledTimerWithTimeInterval:2 target:self selector:nil userInfo:nil repeats:YES];
}

手動で両方向に移動できます。
