在處理多個方向時，我應該使用哪些最佳做法？

Question

請原諒我的無知。傳統上，我一直在做這樣的事情，但感覺像很多不必要的工作，我不確定是否有更簡單的方法來實現這一點。

// logoView dimensions 
static const CGFloat LOGO_VIEW_X_PORT = 42; 
static const CGFloat LOGO_VIEW_Y_PORT = 20; 
static const CGFloat LOGO_VIEW_W_PORT = 237; 
static const CGFloat LOGO_VIEW_H_PORT = 82; 
// 
static const CGFloat LOGO_VIEW_X_LAND = 142; 
static const CGFloat LOGO_VIEW_Y_LAND = 20; 
static const CGFloat LOGO_VIEW_W_LAND = 237; 
static const CGFloat LOGO_VIEW_H_LAND = 82; 

- (void)viewDidLoad { 
    [super viewDidLoad]; 

    // init logo view 
    self.logoView = [[UIImageView alloc] initWithImage:...]; 

    // determine device orientation and set dimensions 
    if (self.interfaceOrientation == UIDeviceOrientationPortrait || 
     toInterfaceOrientation == UIDeviceOrientationPortraitUpsideDown) { 
     self.logoView.frame = CGRectMake(LOGO_VIEW_X_PORT, LOGO_VIEW_Y_PORT, LOGO_VIEW_W_PORT, LOGO_VIEW_H_PORT); 
    } else { 
     self.logoView.frame = CGRectMake(LOGO_VIEW_X_LAND, LOGO_VIEW_Y_LAND, LOGO_VIEW_W_LAND, LOGO_VIEW_H_LAND); 
    } 

    [self.view addSubview:self.logoView]; 

} 

- (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration { 
    if (toInterfaceOrientation == UIDeviceOrientationPortrait || 
     toInterfaceOrientation == UIDeviceOrientationPortraitUpsideDown) { 
     self.logoView.frame = CGRectMake(LOGO_VIEW_X_PORT, LOGO_VIEW_Y_PORT, LOGO_VIEW_W_PORT, LOGO_VIEW_H_PORT); 
     // long list of other views... 
    } else { 
     self.logoView.frame = CGRectMake(LOGO_VIEW_X_LAND, LOGO_VIEW_Y_LAND, LOGO_VIEW_W_LAND, LOGO_VIEW_H_LAND); 
     // long list of other views... 
    } 
} 

有沒有更好的協議，我應該下做到這一點，還是這或多或少大家如何處理多個方向？

Answer 1

看看所有圖形對象的autoResizingMask選項。這應該有所幫助。
