CGRect爲不同的iphone ipad方向

Question

對於以下代碼，我需要根據iphone和ipad方向設置不同的UIIMageView位置。

// Animated images - centered on screen 
animatedImages = [[UIImageView alloc] initWithFrame:CGRectMake(
(SCREEN_WIDTH/2) - (IMAGE_WIDTH/2), 
(SCREEN_HEIGHT/2) - (IMAGE_HEIGHT/2) + STATUS_BAR_HEIGHT, 
IMAGE_WIDTH, IMAGE_HEIGHT)]; 

由於CGRect將爲ipad肖像，iphone肖像，ipad風景和iphone風景不同。

如何做到這一點

if (Ipad Portrait orientation) 
{ 
code with different position using CGRectMake (...............) 
} 
if (Iphone Portrait orientation) 
{ 
code with different position using CGRectMake (...............) 
} 
if (Ipad Landscape orientation) 
{ 
code with different position using CGRectMake (...............) 
} 
if (Iphone Landscape orientation) 
{ 
code with different position using CGRectMake (...............) 
} 

Answer 1

你可以使用UIViewController的interfaceOrientation財產。它會給你以下值之一：

UIInterfaceOrientationPortrait， UIInterfaceOrientationPortraitUpsideDown， UIInterfaceOrientationLandscapeLeft， UIInterfaceOrientationLandscapeRight

你的代碼是這樣：

if (self.interfaceOrientation == UIInterfaceOrientationPortrait) 
{ 
    ... 
} 
else if // etc. 

Answer 2

您可以

iPhone和iPad之間的區別

if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) 
{ 
    // The device is an iPad running iPhone 3.2 or later. 
} 
else 
{ 
    // The device is an iPhone or iPod touch. 
} 

，你可以用

if (UIInterfaceOrientationIsLandscape(self.interfaceOrientation)) 
{ 
    // The device is in landscape. 
} 
else 
{ 
    // The device is in portrait. 
}
