IOS实现基于CMPedometer的计步器

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:
