常用的几种权限设置

一、相机权限：
判断是否已开启相机权限yes是开启：

- (BOOL)requestCaptureDeviceAuthor {AVAuthorizationStatus authStatus =[AVCaptureDevice authorizationStatusForMediaType:AVMediaTypeVideo];if (authStatus == AVAuthorizationStatusDenied ||authStatus == AVAuthorizationStatusRestricted ||authStatus == AVAuthorizationStatusNotDetermined) {return NO;}return YES;
}

判断是否已询问相机权限：
authStatus==AVAuthorizationStatusNotDetermined时表示为询问相机权限，需要系统弹框提示开启或拒绝：调用requestAccessForMediaType方法就会掉漆系统弹框询问，如下代码：

AVAuthorizationStatus authStatus =[AVCaptureDevice authorizationStatusForMediaType:AVMediaTypeVideo];
if (authStatus == AVAuthorizationStatusNotDetermined) {// 回调函数在任意队列，包括分线程。[AVCaptureDevicerequestAccessForMediaType:AVMediaTypeVideocompletionHandler:^(BOOL granted) {dispatch_async(dispatch_get_main_queue(), ^{if (granted) {// 再次判断用户是否同意授权authorityPermisstion =[self requestCaptureDeviceAuthor];进行跳转或其他操作。}});}];return;
}

二、相册权限：
判断是否已开启相册权限yes是开启：

#import <Photos/Photos.h>
- (BOOL)photoAuthority {PHAuthorizationStatus photoAuthStatus = [PHPhotoLibrary authorizationStatus];if (photoAuthStatus ==PHAuthorizationStatusNotDetermined) {  // 未询问是否授权 可以用下面的请求授权方法询问用户return NO;} else if (photoAuthStatus == PHAuthorizationStatusRestricted ||photoAuthStatus == PHAuthorizationStatusDenied) {  // 未授权return NO;}// 已授权return YES;
}

当PHAuthorizationStatus == PHAuthorizationStatusNotDetermined代表权限未询问，需要调用PHPhotoLibrary requestAuthorization方法进行弹框询问：

PHAuthorizationStatus oldStatus = [PHPhotoLibrary authorizationStatus];
if (oldStatus == PHAuthorizationStatusNotDetermined) {[PHPhotoLibrary requestAuthorization:^(PHAuthorizationStatus status) {dispatch_async(dispatch_get_main_queue(), ^{if (status != PHAuthorizationStatusNotDetermined) {// 再次判断相册当前权限状态是否已开启authorityPermisstion = [self photoAuthority];进行其他操作}});}];
}

三、通讯录权限
判断是否已开启通讯录权限yes是开启：

#import <Contacts/Contacts.h>
#import <ContactsUI/ContactsUI.h>
- (BOOL)addressBookAuthority {if ([CNContactStore authorizationStatusForEntityType:CNEntityTypeContacts] != CNAuthorizationStatusAuthorized) {return NO;}return YES;
}

当[CNContactStore authorizationStatusForEntityType:CNEntityTypeContacts] ==CNAuthorizationStatusNotDetermined时表示权限未询问，通过调用requestAccessForEntityType来进行弹框询问，如下代码：

   if ([CNContactStoreauthorizationStatusForEntityType:CNEntityTypeContacts] ==CNAuthorizationStatusNotDetermined) {// 未询问CNContactStore* contactStore = [[CNContactStore alloc] init];[contactStorerequestAccessForEntityType:CNEntityTypeContactscompletionHandler:^(BOOL granted, NSError* _Nullable error) {[ISTools performCodeAtMainTheard:^{if (granted) {// 再次判断是否已开启通讯录权限authorityPermisstion = [self addressBookAuthority];进行其他操作}}];}];}

四、麦克风权限
判断麦克风权限是否已开启

#import <AVFoundation/AVFoundation.h>
- (BOOL)audioAuthority {BOOL state = YES;AVAuthorizationStatus authStatus =[AVCaptureDevice authorizationStatusForMediaType:AVMediaTypeAudio];switch (authStatus) {case AVAuthorizationStatusNotDetermined: {  // 没有询问是否开启麦克风state = NO;} break;case AVAuthorizationStatusRestricted: {  // 未授权，家长限制state = NO;} break;case AVAuthorizationStatusDenied: {  // 玩家未授权 提示：“亲，麦克风权限已关闭，请在系统“设置”-“隐私”-“麦克风”-“热门直播”里开启”state = NO;} break;case AVAuthorizationStatusAuthorized: {  // 玩家授权state = YES;} break;}return state;
}

当authStatus == AVAuthorizationStatusNotDetermined时，代表权限从未询问过，需调用requestAccessForMediaType方法进行弹框询问，如下代码：

AVAuthorizationStatus authStatus =[AVCaptureDevice authorizationStatusForMediaType:AVMediaTypeAudio];
if (authStatus == AVAuthorizationStatusNotDetermined) {[AVCaptureDevicerequestAccessForMediaType:AVMediaTypeAudiocompletionHandler:^(BOOL granted) {dispatch_async(dispatch_get_main_queue(), ^{if (granted) {// 用户同意授权authorityPermisstion = [self audioAuthority];进行其他操作}});}];
}

五、地理位置权限
判断是否已开启地理位置使用权限，yes已允许使用位置：

#import <CoreLocation/CoreLocation.h>
- (BOOL)isOpenLocation {if ([CLLocationManager locationServicesEnabled] &&([CLLocationManager authorizationStatus] ==kCLAuthorizationStatusAuthorizedAlways ||[CLLocationManager authorizationStatus] ==kCLAuthorizationStatusAuthorizedWhenInUse)) {return YES;} else {return NO;}
}

当[CLLocationManager locationServicesEnabled] &&CLLocationManager authorizationStatus] == kCLAuthorizationStatusNotDetermined时代表从未询问过位置权限，需requestWhenInUseAuthorization方法进行弹框询问，如下代码：

if ([CLLocationManager locationServicesEnabled] &&[CLLocationManager authorizationStatus] ==kCLAuthorizationStatusNotDetermined) {if (!self.locManager) {self.locManager = [[CLLocationManager alloc] init];self.locManager.delegate = self;}[self.locManager requestWhenInUseAuthorization];return;
}

弹框询问是否开启使用位置后，通过CLLocationManagerdelegate方法-- (void)locationManager:(CLLocationManager*)manager
didChangeAuthorizationStatus:(CLAuthorizationStatus)status进行回调得知询问的结果status。

#pragma mark--CLLocationManagerdelegate
- (void)locationManager:(CLLocationManager*)managerdidChangeAuthorizationStatus:(CLAuthorizationStatus)status {if (status == kCLAuthorizationStatusAuthorizedAlways ||status == kCLAuthorizationStatusAuthorizedWhenInUse) {
//   [self pushAuthoritySetViewControllerWithTitle:@"地理位置"
//                              authorityDescString:
//                                  @"若您授权地理位置权限，该权限将用于发现附近"
//                                  @"的直播内容，当您开播时也会推荐给附近的人观"
//                                  @"看，建议您允许以保证体验的流畅"
//                             authorityPermisstion:[self isOpenLocation]];  }
}
