（一）、获取定位权限
1、在Info.plist添加配置 （可根据情况任选其一，也可以两者都添加）

2、向系统注册权限（可根据情况任选其一，也可以两者都添加，与Info.plist中添加的配置对应）
#import <CoreLocation/CoreLocation.h> //添加定位服务头文件（不可缺少）
@interface ViewController ()<CLLocationManagerDelegate>{//添加代理协议 CLLocationManagerDelegate
CLLocationManager *_locationManager;//定位服务管理类
}
- (void)viewDidLoad
{
[super viewDidLoad];
_locationManager = [[CLLocationManager alloc] init];
_locationManager = self;
[_locationManager requestWhenInUseAuthorization];
// [_locationManager requestAlwaysAuthorization];
}
3、当应用启动时，系统会根据应用的注册授权弹出提示框请求用户授权
（弹框的描述信息与Info.plist中配置的描述信息是一直的）

4、当我们点击允许的时候，定位服务开始生效。
此时持续调用代理函数
- (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray<CLLocation *> *)locations{
NSLog(@"定位中....");
}
当点击不允许的使用，分别调用代理函数
- (void)locationManager:(CLLocationManager *)manager didChangeAuthorizationStatus:(CLAuthorizationStatus)status{
NSLog(@"授权状态改变");
if (status == kCLAuthorizationStatusDenied) {
NSLog(@"定位权限没开启");
UIAlertController *alertController = [UIAlertController alertControllerWithTitle:@"打开定位,发现活动" message:nil preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction *cancelAction = [UIAlertAction actionWithTitle:@"暂不" style:(UIAlertActionStyleCancel) handler:^(UIAlertAction * _Nonnull action) {
[self.navigationController popViewControllerAnimated:YES];
}];
UIAlertAction *confrmAction = [UIAlertAction actionWithTitle:@"打开" style:(UIAlertActionStyleDefault) handler:^(UIAlertAction * _Nonnull action) {
NSURL *url = [NSURL URLWithString:@"App-Prefs:root=LOCATION_SERVICES"];
if ([[UIApplication sharedApplication]canOpenURL:url]) {
[[UIApplication sharedApplication]openURL:url options:@{} completionHandler:nil];
}
}];
[alertController addAction:cancelAction];
[alertController addAction:confrmAction];
[self presentViewController:alertController animated:YES completion:nil];
}
}
- (void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error{
NSString *errorString;
NSLog(@"定位失败原因: %@",[error localizedDescription]);
}
5、手机设置中的界面

（二）、获取蓝牙权限
1、首先在build phase中添加CoreBluetooth.framework
#import <CoreBluetooth/CoreBluetooth.h>
@interface BlueToothState()<CLLocationManagerDelegate>
@property (nonatomic,strong)CBCentralManager *centralManager;
-(void)viewDidLoad{
// 蓝牙检测
self.centralManager = [[CBCentralManager alloc] initWithDelegate:self queue:nil options:nil];
}
2、实现蓝牙代理
#pragma mark - CLLocationManagerDelegate
//每次蓝牙状态改变都会回调这个函数
- (void)centralManagerDidUpdateState:(CBCentralManager *)central{
if(central.state == CBManagerStatePoweredOn)
{
NSLog(@"蓝牙设备开着");
}
else if (central.state == CBManagerStatePoweredOff)
{
NSLog(@"蓝牙设备关着");
UIAlertController *alertController = [UIAlertController alertControllerWithTitle:@"打开蓝牙,匹配活动" message:nil preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction *cancelAction = [UIAlertAction actionWithTitle:@"暂不" style:(UIAlertActionStyleCancel) handler:^(UIAlertAction * _Nonnull action) {
[self.navigationController popViewControllerAnimated:YES];
}];
UIAlertAction *confrmAction = [UIAlertAction actionWithTitle:@"打开" style:(UIAlertActionStyleDefault) handler:^(UIAlertAction * _Nonnull action) {
NSURL *url = [NSURL URLWithString:@"App-Prefs:root=Bluetooth"];
if ([[UIApplication sharedApplication]canOpenURL:url]) {
[[UIApplication sharedApplication]openURL:url options:@{} completionHandler:nil];
}
}];
[alertController addAction:cancelAction];
[alertController addAction:confrmAction];
[self presentViewController:alertController animated:YES completion:nil];
}else {
NSLog(@"该设备蓝牙未授权或者不支持蓝牙功能");
}
}
