Detect the shake gesture in iOS objective C and swift

Solution:

You can detect the shake gesture using the motion event detector.

Objective C:

- (void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event

{

    if ( event.subtype == UIEventSubtypeMotionShake )

    {

    NSLog(@"shake detected")

    }

    

    if ( [super respondsToSelector:@selector(motionEnded:withEvent:)] )

        [super motionEnded:motion withEvent:event];

}

Swift:

override func motionEnded(_ motion: UIEventSubtype, with event: UIEvent?) {
    if motion == .motionShake {
        print("shake detected")
    }
}
