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) {dispatch_async(dispatch_get_main_queue(), ^{_stepLabel.text = [NSString stringWithFormat:@"步数：%@步", stepValue];});}];}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];});}];}}];
}
