无法在模拟器中检测到iPhone Retina 4英寸屏幕尺寸 [英] Unable to detect iPhone Retina 4-inch screen size in simulator

问题描述

我想让我的iOS应用程序支持iPhone 5.所以我为iPhone 5大小创建了一个单独的xib集。然后我通过检查屏幕高度加载每个xib。

I want to make my iOS application support iPhone 5. So I created a separate xib set for iPhone 5 size. Then I load each xib by checking the screen height.

这是AppDelegate.m中的启动画面加载代码：

This is the splash screen loading code inside the AppDelegate.m:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:    (NSDictionary *)launchOptions
{
    self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
    // Override point for customization after application launch.
    UIViewController *viewController1;
    if ([UIScreen mainScreen].bounds.size.height==480) {
        viewController1 = [[SplashScreen alloc] initWithNibName:@"SplashScreen" bundle:nil];
    }


    if ([UIScreen mainScreen].bounds.size.height==568) {
        viewController1 = [[SplashScreen alloc] initWithNibName:@"SplashScreen5" bundle:nil];
    }

    self.window.rootViewController = viewController1;
    [self.window makeKeyAndVisible];
    return YES;
}

但当我将模拟器更换为Retina 4英寸时，我的代码没有'获得模拟器大小。如果条件，它总是执行480 。

But when I change the simulator into Retina 4-inch, my code doesn't get the emulator size. It always executes the 480 if condition.

但是我创建的其他应用程序正常运行。

这是什么原因？

But other apps I created like this are working properly.
What is the reason for this?

推荐答案

我现在遇到了完全相同的问题（当然是在最糟糕的时刻......）。
它确实工作了几个星期，由于一个未知的原因，模拟器突然将4英寸模拟设备视为3.5英寸屏幕。
清理，重置，重启：同样的情况...

I'm having the exact same problem right now (at the worst moment, of course....). It did work properly for several weeks, and for a unknown reason, the simulator suddenly considers the 4in simulated device as a 3.5in screen. cleaning, reset, reboot : same situation...

编辑：好的，问题解决了。 T'是因为-568 @ 2x格式中缺少默认图像。我知道这是使系统工作的一个条件，但xcode显然决定摆脱我选择的那个。哦，好吧......

EDIT : ok, problem solved. T'was because of a missing Default image in the -568@2x format. I knew that was a condition to make the system work, but xcode had apparently decided to get rid off the one I chose. oh well...
