Splash-screen rotation not woking in Landscape mode on iOS devices

问题

I took over a project using AngularJS, Ionic and Bootstrap to create hybrid apps for mobile devices.

Prior to upgrade to XCode 7 all went well. I updated my HTML-, CSS- and JS-code in editor, ran grunt run:ios to create platform code and opened XCode. From there I built the .ipa-file without any issues (just with some warnings, which could be ignored).

However since using XCode 7 (needed for iOS 8- and iOS 9-devices), the splascreen will be shown incorrectly. Meaning: In Portrait mode.

Note #1: The splash-screen and the app have to be Landscape-only.

Note #2: When running grunt run:android, all is well on the Android-based device.

Per 34919547 I updated the cordova-plugin-splashscreen plugin to version 3.1.0 as suggested herein. I also changed a reference, as the old version was hard-coded in a config-file.

Now first the splash-screen is shown by mistake in Portraid mode, then (after the defined timeout) in Landscape mode as it should. So things go a little bit better, but not by 100%.

How to get the splash-screen shown entirely in Landscape mode?

Did you try cancelling out this line of code?

{
    static dispatch_once_t onceToken;
    dispatch_once(&onceToken, ^{
        Class class = [self class];

        SEL originalSelector = @selector(shouldAutorotate);
        SEL swizzledSelector = @selector(splash_shouldAutorotate);

        Method originalMethod = class_getInstanceMethod(class, originalSelector);
        Method swizzledMethod = class_getInstanceMethod(class, swizzledSelector);

        BOOL didAddMethod = class_addMethod(class,
                                            originalSelector,
                                            method_getImplementation(swizzledMethod),
                                            method_getTypeEncoding(swizzledMethod));

        if (didAddMethod) {
            class_replaceMethod(class,
                                swizzledSelector,
                                method_getImplementation(originalMethod),
                                method_getTypeEncoding(originalMethod));
        } else {
            method_exchangeImplementations(originalMethod, swizzledMethod);
        }
    });
}

Try cancel it out like this:

{
    /*
    static dispatch_once_t onceToken;
    dispatch_once(&onceToken, ^{
        Class class = [self class];

        SEL originalSelector = @selector(shouldAutorotate);
        SEL swizzledSelector = @selector(splash_shouldAutorotate);

        Method originalMethod = class_getInstanceMethod(class, originalSelector);
        Method swizzledMethod = class_getInstanceMethod(class, swizzledSelector);

        BOOL didAddMethod = class_addMethod(class,
                                            originalSelector,
                                            method_getImplementation(swizzledMethod),
                                            method_getTypeEncoding(swizzledMethod));

        if (didAddMethod) {
            class_replaceMethod(class,
                                swizzledSelector,
                                method_getImplementation(originalMethod),
                                method_getTypeEncoding(originalMethod));
        } else {
            method_exchangeImplementations(originalMethod, swizzledMethod);
        }
    });
    */
}
