iOS中各个权限功能提醒弹框

1. 麦克风权限

• 单存检测能否有麦克风权限，并不会弹出能否允许弹出权限提醒框

#import <AVFoundation/AVFoundation.h>/** 判断当前是有语音权限,但是不会弹出能否允许弹出权限 （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;}

• 检测能否有权限，假如没有受权过，会弹出能否允许提醒框

#import <AVFoundation/AVFoundation.h>/** 判断当前是有语音权限,会弹出能否允许弹出权限 （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

• 检测能否有访问相册权限，并不会弹出能否允许访问相册权限提醒框

#import <Photos/Photos.h>#import <AssetsLibrary/AssetsLibrary.h>/** 判断相册权限开关,但是不会弹出能否允许弹出权限 (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;}

• 检测能否有权限，假如没有受权过，会弹出能否允许提醒框

#import <Photos/Photos.h>/** 判断相册权限开关,会弹出能否允许弹出权限 (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) { //弹出访问权限提醒框        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

• 检测能否有相机拍照权限，并不会弹出能否允许提醒框

#import <AVFoundation/AVFoundation.h>/** 判断相机权限开关,但是不会弹出能否允许弹出权限 (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;}

• 检测能否有过受权，假如没有受权过，会弹出能否允许提醒框

#import <AVFoundation/AVFoundation.h>/** 判断相机权限开关,会弹出能否允许弹出权限 (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) { // 受权成功                // 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 { // 拒绝受权                // do something            }        });    }];}

4. 推送权限(远程、本地)

• 检测能否有推送权限，并不会弹出能否允许提醒框

/** 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;}

• 检测能否有过受权，假如没有受权过，会弹出能否允许提醒框

说明：这里仅仅是检测能否受权过，弹出提醒框操作。至于远程注册少量流程请参见另一篇博客。iOS 通知权限(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,会弹出能否允许弹出权限(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，能否允许权限            });        }];    } 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，能否允许权限    }}
