iOS shake-shake function

There's a way to do this in Uiresponder.

-(void) Motionbegan: (uieventsubtype) motion withevent: (uievent *) event __osx_ Available_starting(__MAC_NA,__IPHONE_3_0);

-(void) motionended: (uieventsubtype) motion withevent: (uievent *) event __osx_ Available_starting(__MAC_NA,__IPHONE_3_0);

-(void) motioncancelled: (uieventsubtype) motion withevent: (uievent *) event __osx_ Available_starting(__MAC_NA,__IPHONE_3_0);

This is the way to perform a shake. So how do you use these methods?

Very simple, you just have to let the controller itself support shaking

At the same time let him be the first corresponding person:

-(void) viewdidload

{

[Superviewdidload];

Additional setup after loading the view, typically from a nib.

[[uiapplicationsharedapplication] setapplicationsupportsshaketoedit:YES ];

[self becomefirstresponder];

}

And then we can get to the next few ways.

-(void) Motionbegan: (uieventsubtype) motion withevent: (uievent *) event

{

// Shake detected

}

-(void) motioncancelled: (uieventsubtype) motion withevent: (uievent *) event

{

// Shake Cancel

}

-(void) motionended: (uieventsubtype) motion withevent: (uievent *) event

{

// Shake end

if (event. subtype  ==  Uieventsubtypemotionshake) {

//something happens

}

}

As for the interface I will not write ~
