iOS检测摇动

         iOS 检测摇动，最常见的就是微信摇一摇，查找附近的人。

        新建一个CWindow类继承UIWindow，重写-(void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event方法。

        .h文件代码：

#import <UIKit/UIKit.h>@interface CWindow : UIWindow@end

//#import "CWindow.h"
#import "CConstants.h"@implementation CWindow- (id)initWithFrame:(CGRect)frame
{self = [super initWithFrame:frame];if (self) {// Initialization code}return self;
}//检测摇动
-(void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event
{if(event.type == UIEventSubtypeMotionShake){CCLog(@"Motion shake.");[[NSNotificationCenter defaultCenter] postNotificationName:APP_SHAKE_NOTIFICATION object:nil];}
}/*
// Only override drawRect: if you perform custom drawing.
// An empty implementation adversely affects performance during animation.
- (void)drawRect:(CGRect)rect
{// Drawing code
}
