Question

对于以下代码，我需要根据iphone和ipad方向设置不同的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)];

因为CGRect对于ipad肖像，iphone肖像，ipad风景和iphone风景将有所不同。

我该怎么做

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

您可以使用UIViewController的interfaceOrientation属性。它将为您提供以下值之一：

UIInterfaceOrientationPortrait， UIInterfaceOrientationPortraitUpsideDown， UIInterfaceOrientationLandscapeLeft， UIInterfaceOrientationLandscapeRight

您的代码如下：

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

Answer 2

您可以使用

区分iPhone和iPad

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.
}

您可以使用

区分肖像和风景

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

现在将其组合起来以获得您喜欢的自定义。
