視圖之間切換

Question

我有兩個觀點將其命名爲具有縱向和橫向上的旋轉，我想切換views.But當負載它工作正常，但在旋轉它不是working.please電話我來解決這個問題

-(void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration 
{ 
    if (toInterfaceOrientation == UIInterfaceOrientationPortrait || toInterfaceOrientation == UIInterfaceOrientationPortraitUpsideDown) 
    { 
     self.view = self.portrait;  
    } 
    else 
    { 
     self.view = self.landscape; 
    } 
} 

Answer 1

您必須實現

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation 

功能在你的MainViewController類，使自轉的工作。看看它的參考：Reference Documentation on ViewControllers

你可以簡單地說（支持所有方向）：

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { 
    return YES; 
} 

Answer 2

假設你有你的項目設置中設置了支撐取向，你可以這樣做：

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { 
    return YES; 
} 

添加這將使視圖控制器的權限實際上影響您在willRotateToInterfaceOrientation中所做的更改。

另外，嘗試使用此代碼視圖之間切換：

-(void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation 
    duration:(NSTimeInterval)duration { 
    if (toInterfaceOrientation == UIInterfaceOrientationPortrait || 
     toInterfaceOrientation == UIInterfaceOrientationPortraitUpsideDown) { 
     [UIView transitionFromView:self.view 
         toView:self.portrait 
         duration:0.7 
         options:UIViewAnimationOptionTransitionFlipFromLeft 
        completion:^(BOOL finished){ 
         //do something when done with animation 
         }]; 
    } else { 
     [UIView transitionFromView:self.view 
         toView:self.landscape 
         duration:0.7 
         options:UIViewAnimationOptionTransitionFlipFromLeft 
        completion:^(BOOL finished){ 
         //do something when done with animation 
         }]; 
    } 
}
