IOS实现基于CMPedometer的计步器
作者：ling_fengxue
这篇文章主要为大家详细介绍了IOS实现基于CMPedometer的计步器，具有一定的参考价值，感兴趣的小伙伴们可以参考一下
CMStepCount类在IOS8已经不推荐使用了,IOS8推荐使用CMPedometer类来处理用户健康和运动信息.下面是一个小小的demo来演示下,如何使用它,以及一些注意事项.
#import "ViewController.h"
#import <CoreMotion/CoreMotion.h>
@interface ViewController ()
@property (weak, nonatomic) IBOutlet UILabel *stepLabel;
@property(nonatomic,strong) CMPedometer *stepter;
@property (weak, nonatomic) IBOutlet UILabel *totalLabel;
@end
@implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
if(![CMPedometer isStepCountingAvailable])
{
NSLog(@"计步器不可用");
return;
}
_stepter =[[CMPedometer alloc]init];
NSTimeInterval secondsPerDay =24*60*60;
NSDate *date =[NSDate date];
NSDate *yesterDay =[date dateByAddingTimeInterval:-secondsPerDay];
[_stepter startPedometerUpdatesFromDate:yesterDay withHandler:^(CMPedometerData * _Nullable pedometerData, NSError * _Nullable error) {
if(error)
{
NSLog(@"error ==%@",error);
}else
{
NSNumber *steps =pedometerData.numberOfSteps;
NSNumber *distance =pedometerData.distance;
NSDictionary *dic =@{
@"steps":steps,
@"distance":distance
};
NSLog(@"过去一天你一共走了%@步,一共%@米",steps,distance);
[self performSelectorOnMainThread:@selector(refreshUI:) withObject:dic waitUntilDone:NO];
}
}];
}
-(void)refreshUI:(NSDictionary *)dic
{
NSNumber *distance =dic[@"distance"];
float meters =[distance floatValue];
self.stepLabel.text =[NSString stringWithFormat:@"%@",dic[@"steps"]];
self.totalLabel.text =[NSString stringWithFormat:@"%.2f",meters];
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
@end
此处还有一点需要注意:就是请在info.plist文件中加入你要访问用户健康和运动信息的描述,如下图
运行结果如下:
