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.
我要评论
#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:
