ios - 关于UIWindow的一点疑问

Answer 1

你也可以做到

@interface KeyboardWindow : UIWindow
@property (nonatomic, strong) UIView *keyboardView;
@end

@implementation

- (UIView*)hitTest:(CGPoint)point withEvent:(UIEvent *)event
{
    if (CGRectContainsPoint(self.keyboardView.frame, point))
        return [self.keyboardView hitTest:[self convertPoint:point toView:self.keyboardView]
                          withEvent:event];
    return nil;
}

@end
