iphone - 在 webView 中加载时如何在电影播放器​​中完成按钮操作？

Question

我是 Iphone 新手，正在尝试在 webView 中播放视频。所以，我需要完成按钮操作。请帮帮我。

Answer 1

最后我找到了完成按钮操作的解决方案......这个逻辑也适用于 ipad 和 iphone。我通过使用 UIGestureRecognizer 解决了这个问题。

这是我的代码。

首先，我通过使用为 EnterFullScreen 添加通知

 [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(youTubeStarted:) name:@"UIMoviePlayerControllerDidEnterFullscreenNotification" object:nil];

现在在 youTubeStarted 方法中我添加了这个代码..

-(void)youTubeStarted:(NSNotification *)notification{
if (!tapRecognizer1) {
    tapRecognizer1 = [[UITapGestureRecognizer alloc] init];
    tapRecognizer1.delegate = self;
    [tapRecognizer1 setNumberOfTapsRequired:1];
    [self.view addGestureRecognizer:tapRecognizer1];
}    
}

这会将 TapRecognizer 添加到电影播放器​​中。

现在下面的委托方法将检查它是否完成按钮

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch{
NSLog(@"%@",touch.description);
NSString *ViewName = touch.description ;
CGPoint location = [touch locationInView:touch.view];
NSLog(@"location x===%f , location y=== %f",location.x,location.y);
NSRange Check = [ViewName rangeOfString:@"UINavigationButton"];
NSRange checkFrameOfButton;
if (UI_USER_INTERFACE_IDIOM()==UIUserInterfaceIdiomPad) {
   checkFrameOfButton = [ViewName rangeOfString:@"frame = (7 7; 50 30)"];
    if (checkFrameOfButton.length <= 0) {
        checkFrameOfButton = [ViewName rangeOfString:@"frame = (7 7; 51 30)"];
    } 
}
else {
    checkFrameOfButton = [ViewName rangeOfString:@"frame = (5 7; 48 30)"];
    if (Check.length<=0) {
        Check = [ViewName rangeOfString:@"UIView"];
    }
}
if (location.y<40 && location.x<85 && Check.length>0 && checkFrameOfButton.length>0) {
    [self endplaying];  
    }
    return YES;
}

现在在 endplaying 方法中，你可以做你想做的事......

如果视频在 UIWebView 中播放，那么您可以使用以下代码以及在 webview 中加载 url 的代码来访问视频何时播放以及按下完成按钮时

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(videoPlayStarted:) name:@"UIMoviePlayerControllerDidEnterFullscreenNotification" object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(videoPlayFinished:) name:@"UIMoviePlayerControllerDidExitFullscreenNotification" object:nil];

并且可以通过

BOOL isVideoInFullScreenMode;//Temperory added here.. must be in .h file or at teh top if required
-(void)videoPlayStarted:(NSNotification *)notification{
//Your stuff here
   isVideoInFullScreenMode = YES;
}

-(void)videoPlayFinished:(NSNotification *)notification{
    //Your stuffs here
    isVideoInFullScreenMode = NO;
}
