([[UIScreen mainScreen] scale] == 2.0) & ([[UIScreen mainScreen] bounds].size.height == 568.0)不工作

Question

由于某些原因，这将无法工作，因为我更新到最新的iOS 8的xcode。它不能识别([[UIScreen mainScreen] scale] == 2.0) &

([[UIScreen mainScreen] bounds].size.height == 568.0)

// Indicates game is running on iPad
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {
    CCLOG(@"Running on iPad");
    // it doesn´t recognize this any more
    if ([[UIScreen mainScreen] scale] == 2.0) {
        CCLOG(@"Running on iPad Retina");
    } else {
        CCLOG(@"Running on iPad 2");
    }      
} else {
    CCLOG(@"Running on iPhone");
    // it doesn´t recognize this any more
    if ([[UIScreen mainScreen] bounds].size.height == 568.0) {
        CCLOG(@"Running on iPhone 5");
    } else {
        CCLOG(@"Running on iPhone 4/4S");
    }
}

Answer 1

您需要添加对iPhone 5的支持。为此，您需要将名为Default-568h@2x.png的启动镜像添加到您的项目中。如果没有此图像，iOS将在兼容模式下运行应用程序，即高度= 468

这个问题在前面的其他问题中已经提过了。
