ios - 使用跟随手指ios显示两个隐藏 View
<p><p>您好，我正在为 iPhone 开发一个应用程序，但无法显示 2 个隐藏 View 。
我在这里发布我的 Storyboard:<a href="http://postimg.org/image/v6nhepqqd/" rel="noreferrer noopener nofollow">http://postimg.org/image/v6nhepqqd/</a>
我想显示 View- 当我从左向右滑动手指时显示全部显示，然后我想显示 View- 关于当我从右向左滑动手指时。滑动手势必须类似于 youtube 菜单。
我只使用了一个 ViewController，我将在这里发布我的代码:</p>
<p><strong>ViewController.h</strong></p>
<pre><code>#import <UIKit/UIKit.h>
@interface ViewController : UIViewController <UIScrollViewDelegate>
@property (weak, nonatomic) IBOutlet UIView *viewAllShow;
@property (weak, nonatomic) IBOutlet UIView *viewMain;
@property (weak, nonatomic) IBOutlet UIView *viewAbout;
- (IBAction)buttonAllShow:(id)sender;
- (IBAction)buttonInfo:(id)sender;
@end
</code></pre>
<p><strong>ViewController.m</strong></p>
<pre><code>#import "ViewController.h"
@interface ViewController ()
@property BOOL viewMainShowed;
@end
@implementation ViewController
- (void)viewDidLoad
{
;
// self.viewScroll.contentSize = self.viewAbout.frame.size;
self.viewMainShowed = YES;

// Controllo se la vista nascosta non è già visibile
if (self.viewMain.frame.origin.x == 0) {
// Chiamata alla funzione per la visualizzazione della vista nascosta
;
} else {
// Chiamata alla funzione per nascondere la vista nascosta
;
}
}
- (IBAction)buttonInfo:(id)sender {
if (self.viewMain.frame.origin.x == 0) {
;

<p>我使用了一个 BOOL 变量来检查主视图是否处于事件状态。我在这个网站上创建了移动和检测触摸的代码:<a href="http://divcode.blogspot.it/2012/09/hidden-menu-part-2-following-finger.html" rel="noreferrer noopener nofollow">http://divcode.blogspot.it/2012/09/hidden-menu-part-2-following-finger.html</a>
其他人说我使用 UIPanGestureRecognizer，但是如果我想使用我在这里发布的方法，我应该怎么做？我的问题是，当我尝试在我的模拟器/真实 iPhone 上做一些手势时，它会向我显示错误的 View ，或者它会移动应该为我所做的手势修复的 View 。
我该如何解决这个问题？你能帮我剪下代码吗？
谢谢</p></p>

<p><p>我认为您应该使用另一种方法来解决此问题:使用 UIPanGestureRecognizer 并通过速度检测手势的方向。
再见</p></p>
