跳转到设置界面

- (void)openSettings{
    NSURL *url = [NSURL URLWithString:UIApplicationOpenSettingsURLString];
    if ([[UIApplication sharedApplication] canOpenURL:url]) {
        [[UIApplication sharedApplication] openURL: url options:@{} completionHandler:^(BOOL success) {
            dispatch_async(dispatch_get_main_queue(), ^{
                [self loadData];
            });
            
        }];
    }
}

相机权限

• 相机权限判断是否开启

//Privacy - Camera
+ (BOOL)cameraPrivacy{
    
    AVAuthorizationStatus status = [AVCaptureDevice authorizationStatusForMediaType:AVMediaTypeVideo];
    if (status == AVAuthorizationStatusRestricted || status == AVAuthorizationStatusDenied||status ==AVAuthorizationStatusNotDetermined)
    {
         // 无权限
         // do something...
        return NO;
    }
    return YES;
}

• 相机权限授权

- (void)requestCameraPrivacy{
    
    AVAuthorizationStatus status = [AVCaptureDevice authorizationStatusForMediaType:AVMediaTypeVideo];
    if (status == AVAuthorizationStatusNotDetermined){
        [AVCaptureDevice requestAccessForMediaType:AVMediaTypeVideo completionHandler:^(BOOL granted) {
            if (granted) {
                dispatch_async(dispatch_get_main_queue(), ^{
                    [self loadData];
                });
            }
        }];
    }else{
        [self openSettings];
    }
}

相册权限

• 相册权限判断是否开启

+ (BOOL)photoLibraryPrivacy{
   PHAuthorizationStatus status = [PHPhotoLibrary authorizationStatus];
   if (status == PHAuthorizationStatusRestricted || status == PHAuthorizationStatusDenied||status ==PHAuthorizationStatusNotDetermined)
   {
       // 无权限
       // do something...
        return NO;
    }
    return YES;
}

• 相册权限授权

- (void)requestPhotoLibraryPrivacy{
   
    PHAuthorizationStatus status = [PHPhotoLibrary authorizationStatus];
   if (status ==PHAuthorizationStatusNotDetermined)
   {
       [PHPhotoLibrary requestAuthorization:^(PHAuthorizationStatus status) {
           dispatch_async(dispatch_get_main_queue(), ^{
               [self loadData];
           });
           
       }];
   }else{
       [self openSettings];
   }
}

麦克风权限

• 麦克风权限判断是否开启

+ (BOOL)microPhoneAuthPrivacy{
    AVAuthorizationStatus status = [AVCaptureDevice authorizationStatusForMediaType:AVMediaTypeAudio];
    if (status == AVAuthorizationStatusRestricted || status == AVAuthorizationStatusDenied||status ==AVAuthorizationStatusNotDetermined)
    {
         // 无权限
         // do something...
        return NO;
    }
    return YES;
}

• 授权

//麦克风
-(void) requestMicroPhoneAuth
{
    
    AVAuthorizationStatus status = [AVCaptureDevice authorizationStatusForMediaType:AVMediaTypeAudio];
    if (status == AVAuthorizationStatusNotDetermined){
        [AVCaptureDevice requestAccessForMediaType:AVMediaTypeAudio completionHandler:^(BOOL granted) {
            if (granted) {
                dispatch_async(dispatch_get_main_queue(), ^{
                    [self loadData];
                });
            }
        }];
    }else{
        [self openSettings];
    }
    
}

定位权限

• 定位权限判断是否开启

+ (BOOL)locationPrivacy{
    if ([CLLocationManager locationServicesEnabled]) {
        CLAuthorizationStatus status = CLLocationManager.authorizationStatus;
        if (status == kCLAuthorizationStatusAuthorizedAlways || status == kCLAuthorizationStatusAuthorizedWhenInUse||
            status == kCLAuthorizationStatusAuthorizedAlways) {
            return YES;
        }
        return NO;
    }
    return NO;
}

• 授权
  注意: CLLocationManager 需要写成全局对象，否次会授权框会消失

- (void)requestLocationPrivacy{
   self.locationManager = [CLLocationManager new];
    if ([CLLocationManager locationServicesEnabled]) {
        CLAuthorizationStatus status = CLLocationManager.authorizationStatus;
        if (status == kCLAuthorizationStatusNotDetermined) {
            [self.locationManager requestWhenInUseAuthorization];
        }else{
            [self openSettings];
        }
        
    }
}

通讯录权限

• 通讯录权限判断是否开启

+(BOOL)contactsPrivacy{
    CNAuthorizationStatus status = [CNContactStore authorizationStatusForEntityType:CNEntityTypeContacts];
    return status == CNAuthorizationStatusAuthorized;
    
}

• 授权

- (void)requestAuthorizationForAddressBook {

    CNAuthorizationStatus authorizationStatus = [CNContactStore authorizationStatusForEntityType:CNEntityTypeContacts];
    
    if(authorizationStatus == CNAuthorizationStatusNotDetermined) {
        
        CNContactStore *contactStore = [[CNContactStore alloc] init];
        
        [contactStore requestAccessForEntityType:CNEntityTypeContacts completionHandler:^(BOOL granted, NSError * _Nullable error) {
            
            if(granted) {
                dispatch_async(dispatch_get_main_queue(), ^{
                    [self loadData];
                });
                
            } else{
                NSLog(@"授权失败, error=%@", error);
            }
        }];
        
    }else{
        [self openSettings];
    }

}
