Goal C: Is it possible to intercept all user actions in one class?

Question

Is it possible to intercept all user actions, such as tap, swipe, enter text, etc. in all windows of my application?

Answer 1

As I said in the comments, subclass UIApplicationand override the instance method sendEvent:.

From the documentation for the UIApplication class, method -sendEvent::

Discussion

If you need it, you can intercept incoming events by subclassing UIApplication and overriding this method. For each event you intercept, you must send it by calling [super sendEvent: event] after processing the event in your implementation.

, :

CustomUIApplication.h:

@interface CustomUIApplication:UIApplication
- (void)sendEvent:(UIEvent *)event;
@end

CustomUIApplication.m:

@implementation CustomUIApplication

- (void)sendEvent:(UIEvent *)event
{
    // ...Do your thing...

    [super sendEvent:event];
}
@end
