在
UIResponder中存在这么一套方法
-
(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);
这就是执行摇一摇的方法。那么怎么用这些方法呢？
很简单，你只需要让这个Controller本身支持摇动
同时让他成为第一相应者：
-
(void)viewDidLoad
{
[superviewDidLoad];
//
Do any additional setup after loading the view, typically from anib.
[[UIApplicationsharedApplication]setApplicationSupportsShakeToEdit:YES];
[self
becomeFirstResponder];
}
然后去实现那几个方法就可以了
- (void) motionBegan:(UIEventSubtype)motionwithEvent:(UIEvent
*)event
{
//检测到摇动
}
-
(void) motionCancelled:(UIEventSubtype)motion withEvent:(UIEvent*)event
{
//摇动取消
}
-
(void) motionEnded:(UIEventSubtype)motion withEvent:(UIEvent*)event
{
//摇动结束
if(event.subtype
== UIEventSubtypeMotionShake) {
//somethinghappens
}
}
