override_didMoveToWindow infinite loop when running Xcode 12 and iOS 14

[fpaaske]

This could be related to #91, #154 or #275, but I'm not sure. It works fine on Xcode 12 and iOS 13.5.

We had the same crash detailed above. This apple forum thread explains what is going on here.

We maintain our own fork since this library is no longer being maintained. You can see the changes we made to work around this crash here.

Try to replace override_didMoveToWindow method in UIView+NUI.m with code below, it works for me.

- (void)override_didMoveToWindow
{
    if (self.class != [UIView class]) {
        Method currentMethod = class_getInstanceMethod(self.class, @selector(override_didMoveToWindow));
        Method expectedMethod = class_getInstanceMethod([UIView class], @selector(override_didMoveToWindow));
        if (currentMethod && expectedMethod) {
            /// Both subclass and UIView override method override_didMoveToWindow,
            /// In this case, just invoke method of UIView(original implementation of `didMoveToWindow`).
            if (currentMethod != expectedMethod) {
                ((void (*)(id, Method))method_invoke)(self, expectedMethod);
                return;
            }
        }
    }

    if (!self.isNUIApplied) {
        [self applyNUI];
    }
    [self override_didMoveToWindow];
}
