本文实例为大家分享了iOS计步器实现代码,供大家参考,具体内容如下
#import "ViewController.h" #import <CoreMotion/CoreMotion.h> @interface ViewController () @property (nonatomic, strong) CMStepCounter *conter; @property (weak, nonatomic) IBOutlet UILabel *stepLabel; @end @implementation ViewController - (void)viewDidLoad { [super viewDidLoad]; // 1、判断计步器是否可用 if (![CMStepCounter isStepCountingAvailable]) {return;} // 2、开始计步 [self.conter startStepCountingUpdatesToQueue:[NSOperationQueue mainQueue] updateOn:5 withHandler:^(NSInteger numberOfSteps, NSDate * _Nonnull timestamp, NSError * _Nullable error) { self.stepLabel.text = [NSString stringWithFormat:@"一共走了%ld步", numberOfSteps]; }]; } - (CMStepCounter *)conter{ if (_conter == nil) { _conter = [[CMStepCounter alloc] init]; } return _conter; }
效果图:
