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?

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.

According to me the best way of dealing with such problems and avoiding couple of condition required for checking the the height of device, is using the relative frame for views or any UI element which you are adding to you view for example: if you are adding some UI element which you want should at the bottom of view or just above tab bar then you should take the y origin with respect to your view's height or with respect to tab bar (if present) and we have auto resizing property as well. I hope this will work for you
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
{ // iPhone 6 and iPhone 6+
// Instantiate a new storyboard object using the storyboard file named Storyboard_iPhone6
storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard_iPhone6" bundle:nil];
NSLog(@"loaded iPhone6 Storyboard");
}
else if (iOSDeviceScreenSize.width == 568 || // for iOS devices
iOSDeviceScreenSize.height == 568) // for iOS simulator
{ // iPhone 5 and iPod Touch 5th generation: 4 inch screen (diagonally measured)
// Instantiate a new storyboard object using the storyboard file named Storyboard_iPhone5
storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard_iPhone5" bundle:nil];
NSLog(@"loaded iPhone5 Storyboard");
}
else
{ // iPhone 3GS, 4, and 4S and iPod Touch 3rd and 4th generation: 3.5 inch screen (diagonally measured)
// Instantiate a new storyboard object using the storyboard file named Storyboard_iPhone4
storyboard = [UIStoryboard story boardWithName:@"MainStoryboard_iPhone" bundle:nil];
NSLog(@"loaded iPhone4 Storyboard");
}
}
else if ([UIDevice currentDevice].userInterfaceIdiom == UIUserInterfaceIdiomPad)
{ // The iOS device = iPad
storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard_iPadnew" bundle:nil];
NSLog(@"loaded iPad Storyboard");
}
// rest my code
}
这是一个真正的通用代码,你可以创建3个不同的故事板:
设置你的项目通用模式,用iPhone5 storyboard设置你的主故事iPhone,用ipad target storyboard设置ipad main,现在为iPhone添加新的storyboard target,并修改iPhone 4s或更少的分辨率,现在实现你的appdelegate。m
iPhone4/4s (3/ 3g是一样的)一个iPhone5,并使项目通用,与一个新的Storyboard目标为iPad,现在在AppDelegate。在didFinishLaunching下添加以下代码:
if(UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone){
UIStoryboard *storyBoard;
CGSize result = [[UIScreen mainScreen] bounds].size;
CGFloat scale = [UIScreen mainScreen].scale;
result = CGSizeMake(result.width *scale, result.height *scale);
//----------------HERE WE SETUP FOR IPHONE4/4s/iPod----------------------
if(result.height == 960){
storyBoard = [UIStoryboard storyboardWithName:@"iPhone4_Storyboard" bundle:nil];
UIViewController *initViewController = [storyBoard instantiateInitialViewController];
[self.window setRootViewController:initViewController];
}
//----------------HERE WE SETUP FOR IPHONE3/3s/iPod----------------------
if(result.height == 480){
storyBoard = [UIStoryboard storyboardWithName:@"iPhone4_Storyboard" bundle:nil];
UIViewController *initViewController = [storyBoard instantiateInitialViewController];
[self.window setRootViewController:initViewController];
}
}
return YES;
}
所以你已经为iPhone 3/ 3g /4/4s/5所有一代的iPod和所有类型的iPad创建了一个通用应用程序
记住将所有IMG与myImage.png和myImage@2x.png集成
值得注意的是,在新的Xcode中,你必须将这个图像文件Default-568h@2x.png添加到资产中
有时候(对于预storyboard应用程序),如果布局会有足够的不同,在viewController init中根据设备指定不同的xib是值得的(参见这个问题-你需要修改代码来处理iPhone 5),因为如果你需要不同的图形,再多的自动调整蒙版也不会起作用。
-(id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
NSString *myNibName;
if ([MyDeviceInfoUtility isiPhone5]) myNibName = @"MyNibIP5";
else myNibName = @"MyNib";
if ((self = [super initWithNibName:myNibName bundle:nibBundleOrNil])) {
...
这对于针对旧iOS版本的应用程序非常有用。
