我正在将我的应用程序迁移到 iPhone 应用程序到 iPhone 5 分辨率。我从stackoverflow中的其他问题中看到了这一点：
例子：
CGRect screenBounds = [[UIScreen mainScreen] bounds];
if (screenBounds.size.height == 568) {
// code for 4-inch screen
} else {
// code for 3.5-inch screen
}
但似乎，我需要为我的所有图像添加此代码。有没有更简单的方法？意思是更通用的方式。
谢谢...
Build an app using iOS 6 as the Base SDK and use the Auto Layout feature to make screens that can scale for all type of screens. You'll need Xcode 4.5 to do this. Add a splash image named Default-568h@2x.png
-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
// Return YES for supported orientations
switch (interfaceOrientation) {
case UIInterfaceOrientationPortrait:
case UIInterfaceOrientationPortraitUpsideDown:
//[self ArrangeControllsFor_Protrate];
[self performSelector:@selector(ArrangeControllsFor_Protrate) withObject:Nil afterDelay:0.005f];
return YES;
break;
case UIInterfaceOrientationLandscapeLeft:
case UIInterfaceOrientationLandscapeRight:
[self performSelector:@selector(ArrangeControllsFor_LandScape) withObject:Nil afterDelay:0.005f];
return YES;
break;
}
}
-(void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration{
switch (toInterfaceOrientation){
case UIInterfaceOrientationPortrait:
case UIInterfaceOrientationPortraitUpsideDown:
[self performSelector:@selector(ArrangeControllsFor_Protrate) withObject:Nil afterDelay:0.005f];
break;
case UIInterfaceOrientationLandscapeLeft:
case UIInterfaceOrientationLandscapeRight:
[self performSelector:@selector(ArrangeControllsFor_LandScape) withObject:Nil afterDelay:0.005f];
break;
}
}
-(NSUInteger)supportedInterfaceOrientations{
return UIInterfaceOrientationMaskAll;
}
-(BOOL)shouldAutorotate{
return YES;
}
-(void)ArrangeControllsFor_Protrate{
[[UIApplication sharedApplication] setStatusBarHidden:NO];
[self.view setBounds:CGRectMake(0, 0, 320,568)];
[self.view setFrame:CGRectMake(0, 0, 320, 568)];
}
-(void)ArrangeControllsFor_LandScape{
[[UIApplication sharedApplication] setStatusBarHidden:YES];
[self.view setBounds:CGRectMake(0, 0, 568, 320)];
[self.view setFrame:CGRectMake(0, 0, 568, 320)];
}
- (void)viewWillAppear:(BOOL)animated{
UIInterfaceOrientation statusBarOrientation = [[UIApplication sharedApplication] statusBarOrientation];
if(UIInterfaceOrientationIsPortrait(statusBarOrientation))
{
[self ArrangeControllsFor_Protrate];
}
else
{
[self ArrangeControllsFor_LandScape];
}
}
为 UIImage 类创建一个类别。将此逻辑移至 UIImage 类。
现在将现有的 UIImage 创建函数更改为您在类别中创建的函数。
如果您是注册的 Apple 开发人员，您可以使用 AutoLayout 我推荐您可以从去年的 WWDC 中找到的教程。
检查并在prefix.h文件中写入
#define IPHONE5 ( fabs( ( double )[ [ UIScreen mainScreen ] bounds ].size.height - ( double )568 ) < DBL_EPSILON )
每当您想检查时，只需检查
if (IPHONE 5) {
// Code for iPhone 5 Device
enter code here
} else if (!IPHONE5) {
// Code for 3.5 inch (iphone 4 nad less)
enter code here
}
