iOS中各个权限功能提示弹框

1. 麦克风权限

• 单存检测是否有麦克风权限，并不会弹出是否允许弹出权限提示框

#import <AVFoundation/AVFoundation.h>

/**
 判断当前是有语音权限,但是不会弹出是否允许弹出权限
 （需要在info中配置）Privacy - Microphone Usage Description 允许**访问您的语音，来用于**功能？
 
 @return YES:有权限，NO:没权限
 */
- (BOOL)JX_Device_Permission_AudioAuth {
    AVAuthorizationStatus authStatus = [AVCaptureDevice authorizationStatusForMediaType:AVMediaTypeAudio];
    if (authStatus == AVAuthorizationStatusDenied || authStatus == AVAuthorizationStatusRestricted) {
        return NO;
    }
    return YES;
}

• 检测是否有权限，如果没有授权过，会弹出是否允许提示框

#import <AVFoundation/AVFoundation.h>

/**
 判断当前是有语音权限,会弹出是否允许弹出权限
 （需要在info中配置）Privacy - Microphone Usage Description 允许**访问您的语音，来用于**功能？
 */
- (void)JX_Device_Permission_Check_AudioAuth {
    AVAudioSession *session = [AVAudioSession sharedInstance];
    if ([session respondsToSelector:@selector(requestRecordPermission:)]){
        [session performSelector:@selector(requestRecordPermission:) withObject:^(BOOL granted) {
           // do something
        }];
    }

}

2. 访问相册权限

• 检测是否有访问相册权限，并不会弹出是否允许访问相册权限提示框

#import <Photos/Photos.h>
#import <AssetsLibrary/AssetsLibrary.h>

/**
 判断相册权限开关,但是不会弹出是否允许弹出权限
 (需要在info中配置)Privacy - Photo Library Additions Usage Description 允许**访问您的相册,来用于**功能
 
 @return YES:有权限，NO:没权限
 */
- (BOOL)JX_Device_Permission_PhotoLibraryAuth {
    
    if ([[UIDevice currentDevice].systemVersion floatValue]  >= 8.0) {
        PHAuthorizationStatus authStatus = [PHPhotoLibrary authorizationStatus];
        if(authStatus == PHAuthorizationStatusDenied || authStatus == PHAuthorizationStatusRestricted) {
            return NO;
        }
    } else if ([[UIDevice currentDevice].systemVersion floatValue] >= 6.0 && [[UIDevice currentDevice].systemVersion floatValue] < 8.0) {
        ALAuthorizationStatus authStatus = [ALAssetsLibrary authorizationStatus];
        if(authStatus == ALAuthorizationStatusDenied || authStatus == ALAuthorizationStatusRestricted) {
            return NO;
        }
    }
    return YES;
}

• 检测是否有权限，如果没有授权过，会弹出是否允许提示框

#import <Photos/Photos.h>

/**
 判断相册权限开关,会弹出是否允许弹出权限
 (需要在info中配置)Privacy - Photo Library Additions Usage Description 允许**访问您的相册,来用于**功能
 */
- (void)JX_Device_Permission_Check_PhotoLibraryAuth{
    
    BOOL auth = [UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypePhotoLibrary];
    if (!auth) return;
    [PHPhotoLibrary requestAuthorization:^(PHAuthorizationStatus status) { //弹出访问权限提示框
        if (status == PHAuthorizationStatusAuthorized) { // 有权限
            dispatch_async(dispatch_get_main_queue(),^{
               // do something
               //  一般操作
              self.imagePickerController.sourceType   = UIImagePickerControllerSourceTypePhotoLibrary;
              [self presentViewController:self.imagePickerController animated:YES completion:nil];
            });
        } else {
            dispatch_async(dispatch_get_main_queue(),^{ // 无权限
               // do something
            });
            
        }
    }];
}

3. 访问相机权限

• 检测是否有相机拍照权限，并不会弹出是否允许提示框

#import <AVFoundation/AVFoundation.h>

/**
 判断相机权限开关,但是不会弹出是否允许弹出权限
 (需要在info中配置)Privacy - Camera Usage Description 允许**访问您的相机,来用于**功能
 
 @return YES:有权限，NO:没权限
 */
- (BOOL)JX_Device_Permission_CameraAuth {
    AVAuthorizationStatus authStatus = [AVCaptureDevice authorizationStatusForMediaType:AVMediaTypeVideo];
    if (authStatus == AVAuthorizationStatusDenied || authStatus == AVAuthorizationStatusRestricted) {
        return NO;
    }
    return YES;
}

• 检测是否有过授权，如果没有授权过，会弹出是否允许提示框

#import <AVFoundation/AVFoundation.h>

/**
 判断相机权限开关,会弹出是否允许弹出权限
 (需要在info中配置)Privacy - Camera Usage Description 允许**访问您的相机,来用于**功能
 */
- (void)JX_Device_Permission_Check_CameraAuth {
    BOOL auth = [UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera];
    if (!auth) permission(NO);
    NSString *mediaType = AVMediaTypeVideo;//读取媒体类型
    [AVCaptureDevice requestAccessForMediaType:mediaType completionHandler:^(BOOL granted) {
        dispatch_async(dispatch_get_main_queue(),^{
            if (granted) { // 授权成功
                // do something
                // 一般会做的操作，跳转到系统的相机
                self.imagePickerController.sourceType   = UIImagePickerControllerSourceTypeCamera;
                [self presentViewController:self.imagePickerController animated:YES completion:nil];
            } else { // 拒绝授权
                // do something
            }
        });
    }];
}

4. 推送权限(远程、本地)

• 检测是否有推送权限，并不会弹出是否允许提示框

/**
 推送权限开关
 
 @return YES:有权限，NO:没权限
 */
- (BOOL)JX_Device_Permission_NotificationAuth {
    
    if ([[UIDevice currentDevice].systemVersion floatValue] >= 8.0f) {
        UIUserNotificationSettings *setting = [[UIApplication sharedApplication] currentUserNotificationSettings];
        if (UIUserNotificationTypeNone == setting.types) {
            return  NO;
        }
    } else {
        UIRemoteNotificationType type = [[UIApplication sharedApplication] enabledRemoteNotificationTypes];
        if(UIRemoteNotificationTypeNone == type){
            return  NO;
        }
    }
    return YES;
}

• 检测是否有过授权，如果没有授权过，会弹出是否允许提示框

说明：这里仅仅是检测是否授权过，弹出提示框操作。至于远程注册一些流程请参见另一篇博客。iOS 通知详解(远程通知、本地通知)

#ifdef NSFoundationVersionNumber_iOS_9_x_Max
#import <UserNotifications/UserNotifications.h>
#endif

/**
 判断通知权限开关,会弹出是否允许弹出权限(远程、本地)
 */
- (void)JX_Device_Permission_Check_NotificationAuth {
    if ([[UIDevice currentDevice].systemVersion floatValue]  >= 10.0) {
        [[UNUserNotificationCenter   currentNotificationCenter] requestAuthorizationWithOptions:(UNAuthorizationOptionBadge | UNAuthorizationOptionSound | UNAuthorizationOptionAlert) completionHandler:^(BOOL granted, NSError * _Nullable error) {
            dispatch_async(dispatch_get_main_queue(), ^{
                // do something
                // 对granted 进行判断，是否允许权限
            });
        }];
    } else if ([[UIDevice currentDevice].systemVersion floatValue]  >= 8.0) {
        UIUserNotificationSettings *setting = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge categories:nil];
        [[UIApplication sharedApplication] registerUserNotificationSettings:setting];
        BOOL auth = [self JX_Device_Permission_NotificationAuth];
        // 对auth 进行判断，是否允许权限
    }
}
