一、摇一摇
直接监听方法就可以
1.用户开始摇晃手机
- (void)motionBegan:(UIEventSubtype)motion withEvent:(UIEvent*)event
2.摇一摇被打断（电话）
- (void)motionCancelled:(UIEventSubtype)motion withEvent:(UIEvent*)event
3.摇一摇结束
- (void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent*)event
二、计步器
1.导入<CoreMotion/CoreMotion.h>框架
2.初始化对象
self.counter=[[CMStepCounter alloc]init];
3.判断计步器是否可用
if(![CMStepCounter isStepCountingAvailable]) {
NSLog(@"计步器不可用");
return;
}
4.开始计步
[self.counter startStepCountingUpdatesToQueue:[NSOperationQueue mainQueue]updateOn:5 withHandler:^(NSInteger numberOfSteps,NSDate *timestamp,NSError *error) {
if(error)return;
self.stepLabel.text= [NSStringstringWithFormat:@"您一共走了%ld步", numberOfSteps];
}];
