Question

我有两个大小适用于iphone 5的故事板和iphone 4的大小。所有这个设备都有6个IOS。所以我有我的代码来检查IOS的版本......

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{


    // 1
    UIStoryboard * mainStoryboard = nil ;
    if ( SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO ( @ "6.0" ) ) {
        mainStoryboard = [ UIStoryboard storyboardWithName : @ "iPhones6.0" bundle : nil ] ;
    } else {
        mainStoryboard = [ UIStoryboard storyboardWithName : @ "iPhones3-5" bundle : nil ] ;
    }

    // 2
    self.window = [ [ UIWindow alloc ] initWithFrame : [ [ UIScreen mainScreen ] bounds ] ] ;
    self.window.rootViewController = [ mainStoryboard instantiateInitialViewController ] ;
    [ self.window makeKeyAndVisible ] ;




    return YES;
}

如果我有iphone 4与6 iOS和iphone也有6 IOS，我有大尺寸显示器和iPhone但但iPhone 4无法正常工作。那我怎么知道我使用了什么设备，以便检查模型。

Answer 2

您首先没有正确检查。

您可以使用 UIScreen 来获取屏幕大小并确定使用的设备。此外，如果您正在为 iOS 6 进行开发，那么您只需要 1个故事板，并且可以对控制器使用 Autolayout 选项并创建 NSLayoutContrains 来自界面构建器。

这应该比为每部iPhone配备2个stroyboards容易得多。

Answer 3

您不应该根据iOS版本选择故事板，而是根据屏幕大小选择它。喜欢这个

CGRect screenBounds = [[UIScreen mainScreen] bounds];
    if (screenBounds.size.height == 568) {
        //device is iphone 5
        //add storyboard that have large screen (320*568)
    } else {
          //device is iphone 4
          //add story board that have small screen (320*480)

    }

因为在显示我们的屏幕时它与iOS有关，这取决于iPhone屏幕尺寸。

您还可以使用此代码区分iPhone和iPad

if ([[UIDevice currentDevice] userInterfaceIdiom] ==UIUserInterfaceIdiomPhone)
    {
      //device is iPhone
    }
else
    {
      //device is iPad
    }

要区分您设备中的哪个iOS版本，您可以使用此代码，

float currentVersion = 6.0;

if ([[[UIDevice currentDevice] systemVersion] floatValue] >= currentVersion)
{
    //device have iOS 6 or above
}else{
   //device have iOS 5.1 or belove
}

Answer 4

无需为4英寸设备（iPhone 5）和3.5英寸设备（iPhone 4S及更低版本）设置2个故事板。

iPad需要一个单独的故事板，因为屏幕要大得多，但是对于iPhone 5上的额外88个像素的高度来说，并不是真的可以满足额外的要求。

来自iOS6的

AutoLayout解决了这个问题，即使旧的Autoresizing属性也能解决这个问题。

如果你有一个额外的视图（或任何UI元素）仅适用于iPhone 5，那么只需检测Dilip建议的屏幕高度，如果它不是iPhone 5，则使用myElement.hidden = YES;隐藏UI元素。 / p>

CGRect screenBounds = [[UIScreen mainScreen] bounds];
if (screenBounds.size.height <= 480) {
    myElement.hidden = YES;
}

在Xcode的Storyboard视图中，iPhone故事板上的一个按钮可在3.5英寸和4英寸之间切换，因此您可以调整组件位置以适应设备，如左下图所示。
