IOS实现基于CMPedometer的计步器

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. 

									}
