iOS利用HealthKit获取健康里的步数和睡眠时间

最近做一个健康的项目，需要获取运动步数，睡眠时间，于是研究了一下HealthKit，下面分享一下，下来几张图：

一：准备工作
1：在开发者账号（https://developer.apple.com）中配置AppID时需要选中HealthKit。如下图

2：在targets的capabilities中打开HealthKit。如下图

3：infoPlist需要配置权限 NSHealthUpdateUsageDescription 如下图

    <key>NSHealthShareUsageDescription</key>
<string>是否允许更新健康数据</string>
<key>NSHealthUpdateUsageDescription</key>
<string>是否允许分享健康数据</string>

二：创建一个健康的单例管理类HealthKitManager
1：.h文件，解释详见代码注释

/**
 * 健康单例
 */
+ (instancetype)sharedInstance;

/**
 * 检查是否支持获取健康数据
 */
- (void)authorizeHealthKit:(void(^)(BOOL success, NSError *error))compltion;

/**
 * 获取步数
 */
- (void)getStepCount:(void(^)(NSString *stepValue, NSError *error))completion;

/**
 * 获取睡眠
 */
- (void)getSleepCount:(void(^)(NSString *sleepValue, NSError *error))completion;

2：.m文件，解释详见代码注释
注意：
1)：统计步数的时间是，今天00：00：00 - 今天23:59:59
2)：统计睡眠的时间是，昨天12：00：00 - 今天12:00:00

三：控制器UIViewController中调用HealthKitManager

#import "ViewController.h"
#import "HealthKitManager.h"
@interface ViewController ()
//步数
@property(nonatomic,strong) UILabel *stepLabel;

//睡眠
@property(nonatomic,strong) UILabel *sleepLabel;
@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
// Do any additional setup after loading the view.
self.view.backgroundColor = [UIColor whiteColor];

UIButton *stepBtn = [UIButton buttonWithType:UIButtonTypeCustom];
    stepBtn.frame = CGRectMake(50, 100, 50, 40);
    [stepBtn setTitle:@"步数" forState:UIControlStateNormal];
    [stepBtn setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
    stepBtn.backgroundColor = [UIColor redColor];
    [self.view addSubview:stepBtn];
    [stepBtn addTarget:self action:@selector(stepBtnClick) forControlEvents:UIControlEventTouchUpInside];

    _stepLabel = [[UILabel alloc] initWithFrame:CGRectMake(110, 100, 200, 40)];
    _stepLabel.backgroundColor = [UIColor greenColor];
    _stepLabel.textAlignment = NSTextAlignmentCenter;
    _stepLabel.textColor = [UIColor blackColor];
    [self.view addSubview:_stepLabel];

UIButton *sleepBtn = [UIButton buttonWithType:UIButtonTypeCustom];
    sleepBtn.frame = CGRectMake(50, 150, 50, 40);
    [sleepBtn setTitle:@"睡眠" forState:UIControlStateNormal];
    [sleepBtn setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
    sleepBtn.backgroundColor = [UIColor redColor];
    [self.view addSubview:sleepBtn];
    [sleepBtn addTarget:self action:@selector(sleepBtnClick) forControlEvents:UIControlEventTouchUpInside];

    _sleepLabel = [[UILabel alloc] initWithFrame:CGRectMake(110, 150, 200, 40)];
    _sleepLabel.backgroundColor = [UIColor greenColor];
    _sleepLabel.textAlignment = NSTextAlignmentCenter;
    _sleepLabel.textColor = [UIColor blackColor];
    [self.view addSubview:_sleepLabel];
}

#pragma mark - 获取步数
- (void)stepBtnClick{
    [[HealthKitManager sharedInstance] authorizeHealthKit:^(BOOL success, NSError *error) {
if (success) {
            [[HealthKitManager sharedInstance] getStepCount:^(NSString *stepValue, NSError *error) {

                });
            }];
        }else{
NSLog(@"=======%@", error.domain);
        }
    }];
}

#pragma mark - 获取睡眠
- (void)sleepBtnClick{
    [[HealthKitManager sharedInstance] authorizeHealthKit:^(BOOL success, NSError *error) {
if (success) {
            [[HealthKitManager sharedInstance] getSleepCount:^(NSString *sleepValue, NSError *error) {
dispatch_async(dispatch_get_main_queue(), ^{
                    _sleepLabel.text = [NSString stringWithFormat:@"睡眠：%@小时", sleepValue];
                });
            }];
        }
    }];
}
