IOS shaking a Shake event

I know, shake it. The following 2 options are available:

First, the direct use of the system to bring the Motionbegan method

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

If the program does not respond to this method, try adding the following method:

-(BOOL) Canbecomefirstresponder

{

return YES;

}

If not, it is recommended to use the second method.

Second, the method of motionbegan+ notice

1. Write Motionbegan method in Appdelegate

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

{

[[nsnotificationcenterdefaultcenter]postnotificationname:@ "Shake" object:self];

}

2. Add a notification to the page where you want to receive notifications

[[Nsnotificationcenterdefaultcenter]addobserver:selfselector: @selector (shakeaction) name:@ "Shake" object:nil];

Write it in the viewdidload.

The shakeaction here is to shake a shake need to call the method, their own changes, the notification name corresponding to the good, can be freely modified.

Three. Other ways to add a shake

/** Shake the end (need to be processed here after the end of the code) */
-(void) motionended: (uieventsubtype) Motion withevent: (uievent *) event
{
Not shaking a motion event
if (Motion! = Uieventsubtypemotionshake) return;

NSLog (@ "motionended");
}

/** Shake to cancel (interrupted, such as sudden call) */
-(void) motioncancelled: (uieventsubtype) Motion withevent: (uievent *) event
{
NSLog (@ "motioncancelled");
}
