新的iPhone 5屏幕有新的纵横比和新的分辨率(640 x 1136像素)。
开发新的应用程序或将现有应用程序转换到新的屏幕尺寸需要什么?
我们应该记住什么,使应用程序“通用”的旧显示器和新的宽屏纵横比?

在单例类中尝试下面的方法:
-(NSString *)typeOfDevice
{
if(UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone)
{
CGSize result = [[UIScreen mainScreen] bounds].size;
if(result.height == 480)
{
return @"Iphone";
}
if(result.height == 568)
{
return @"Iphone 5";
}
}
else{
return @"Ipad";;
}
return @"Iphone";
}

你可以使用自动布局功能,使用iPhone 5屏幕分辨率创建设计,它适用于4英寸和3.5英寸设备,但在这种情况下,你应该有足够的布局管理器知识。
你可以手动检查屏幕大小来确定你在哪个设备上:
#define DEVICE_IS_IPHONE5 ([[UIScreen mainScreen] bounds].size.height == 568)
float height = DEVICE_IS_IPHONE5?568:480;
if (height == 568) {
// 4"
} else {
// 3"
}
我想,它不是在所有情况下都能工作,但在我的特定项目中,它避免了我对nib文件的重复:
在common.h中,你可以根据屏幕高度来做这些定义:
#define HEIGHT_IPHONE_5 568
#define IS_IPHONE ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone)
#define IS_IPHONE_5 ([[UIScreen mainScreen] bounds ].size.height == HEIGHT_IPHONE_5)
在你的基本控制器中:
- (void)viewDidLoad
{
[super viewDidLoad];
if (IS_IPHONE_5) {
CGRect r = self.view.frame;
r.size.height = HEIGHT_IPHONE_5 - 20;
self.view.frame = r;
}
// now the view is stretched properly and not pushed to the bottom
// it is pushed to the top instead...
// other code goes here...
}
Download and install latest version of Xcode. Set a Launch Screen File for your app (in the general tab of your target settings). This is how you get to use the full size of any screen, including iPad split view sizes in iOS 9. Test your app, and hopefully do nothing else, since everything should work magically if you had set auto resizing masks properly, or used Auto Layout. If you didn't, adjust your view layouts, preferably with Auto Layout. If there is something you have to do for the larger screens specifically, then it looks like you have to check height of [[UIScreen mainScreen] bounds] as there seems to be no specific API for that. As of iOS 8 there are also size classes that abstract screen sizes into regular or compact vertically and horizontally and are recommended way to adapt your UI.
在iOS设备和iOS模拟器上测试时,有一个小问题。看起来模拟器(XCode 6.0.1)在[[UIScreen mainScreen] bounds]中给出了宽度和高度的切换值。大小,取决于设备方向。
因此,在确定正确的物理屏幕尺寸时,这可能是一个问题。此代码还有助于区分所有2014年。iPhone型号:
iPhone4s iPhone5(和iPhone5s) iPhone6(及iPhone6+)
它也可以很容易地改变,使区别,如iPhone6从iPhone6+。
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
CGSize iOSDeviceScreenSize = [[UIScreen mainScreen] bounds].size;
if ([UIDevice currentDevice].userInterfaceIdiom == UIUserInterfaceIdiomPhone)

if (iOSDeviceScreenSize.width > 568 || // for iOS devices
iOSDeviceScreenSize.height > 568) // for iOS simulator

storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard_iPhone6" bundle:nil];
NSLog(@"loaded iPhone6 Storyboard");
}
