如何使用现有代码使应用程序在 iPhone 6 上运行

Question

此代码在我的应用程序委托中.....

@implementation AppDelegate

- (UIStoryboard *)grabStoryboard {

    UIStoryboard *storyboard;

    // detect the height of our screen
    int height = [UIScreen mainScreen].bounds.size.height;

    if (height == 480) {
        storyboard = [UIStoryboard storyboardWithName:@"Main3.5" bundle:nil];
        // NSLog(@"Device has a 3.5inch Display.");
    } else if (height == 568) {
        storyboard = [UIStoryboard storyboardWithName:@"Main4.0" bundle:nil];
        // NSLog(@"Device has a 4inch Display.");
    }else {
        storyboard = [UIStoryboard storyboardWithName:@"Main7.0" bundle:nil];
        // NSLog(@"Device is ipad.");
    }

    return storyboard;
}

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary      *)launchOptions
{
    UIStoryboard *storyboard = [self grabStoryboard];

    // show the storyboard
    self.window.rootViewController = [storyboard instantiateInitialViewController];
    [self.window makeKeyAndVisible];

    return YES;
}

这就是我的应用程序在除 iPhone 6 和 6 plus 之外的所有 iOS 设备上的运行方式。我需要添加什么才能使 iPhone 6 和 6 plus 也能正常工作。万一它有帮助。 如果它有帮助，这就是我在视图控制器上需要时分离编码的方式。

#define IS_IPAD (( UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad ) ? YES : NO)
#define IS_IPHONE_5 (([UIScreen mainScreen].scale == 2.f && [UIScreen      mainScreen].bounds.size.height == 568)?YES:NO)
#define IS_RETINA_DISPLAY_DEVICE (([UIScreen mainScreen].scale == 2.f)?YES:NO)

if (IS_IPAD)
{
    //do stuff for iPad
    text.text = [NSString stringWithFormat:@"i am an ipad"];
}
else
{
    if(IS_IPHONE_5)
    {
        //do stuff for 4 inch iPhone screen
        text.text = [NSString stringWithFormat:@"i am an iphone 5 or 5s"];
    }
    else
    {
        //do stuff for 3.5 inch iPhone screen
        text.text = [NSString stringWithFormat:@"i am an iphone 4 or lower"];
    }

}

将此代码粘贴到您的 AppDelegate.m 中

#define SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(v) ([[[UIDevice currentDevice] systemVersion] compare:(v) options:NSNumericSearch] != NSOrderedAscending)

应用程序didFinishLaunchingWithOptions中的以下代码：

if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"6.0")){
     mainStoryboard = [UIStoryboard storyboardWithName:@"MainStoryboard_iPhone" bundle:nil]; }
