自動旋轉視頻從一個UIWebView發揮到風景模式

Question

我有一個UIWebView，充滿這樣：

[myWebView loadHTMLString:@"<iframe src=\"http://www.youtube.com/embed/grTCDFbhKMU\" frameborder=\"0\" allowfullscreen></iframe>" 
baseURL:nil]; 

視頻被正確啓動，但它無法切換到橫向模式。

我已經在關注的ViewController寫這個？

- (void)didRotate:(NSNotification *)notification 
{ 
    UIDeviceOrientation orientation = [[notification object] orientation]; 

    if (orientation == UIDeviceOrientationLandscapeLeft) 
    { 
     [self.newsContent setTransform:CGAffineTransformMakeRotation(M_PI/2.0)]; 
    } 
    else if (orientation == UIDeviceOrientationLandscapeRight) 
    { 
     [self.newsContent setTransform:CGAffineTransformMakeRotation(M_PI/-2.0)]; 
    } 
    else if (orientation == UIDeviceOrientationPortraitUpsideDown) 
    { 
     [self.newsContent setTransform:CGAffineTransformMakeRotation(M_PI)]; 
    } 
    else if (orientation == UIDeviceOrientationPortrait) 
    { 
     [self.newsContent setTransform:CGAffineTransformMakeRotation(0.0)]; 
    } 
} 

有用的改變內容方向，但usesless一旦視頻推出:(

任何想法

Answer 1

你應該返回YES以下方法：

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { 

    //All orientations are accepted except for the upsidedown orientation 
    if(interfaceOrientation != UIInterfaceOrientationPortraitUpsideDown) { 
     return YES; 
    } else { 
     return NO; 
    } 
} 

如果是返回編輯它將旋轉，如果沒有被返回，它將不會旋轉。
