整理下iOS开发中 应用申请常用权限

#import typedef void (^AuthorizedFinishBlock)();@interface LYAuthorizedMaster : NSObject#pragma mark - 摄像头权限+(BOOL)checkCameraAuthority;+(void)cameraAuthorityCheckSuccess:(AuthorizedFinishBlock)_success fail:(AuthorizedFinishBlock)_fail;#pragma mark - 麦克风权限+(BOOL)checkAudioAuthority;+(void)audioAuthorityCheckSuccess:(AuthorizedFinishBlock)_success fail:(AuthorizedFinishBlock)_fail;#pragma mark - 相册权限+(BOOL)checkAlbumAuthority;+(void)albumAuthorityCheckSuccess:(AuthorizedFinishBlock)_success fail:(AuthorizedFinishBlock)_fail;#pragma mark - 推送通知权限+(BOOL)checkPushNotificationAuthority;+(void)pushNotificationAuthorityCheckSuccess:(AuthorizedFinishBlock)_success fail:(AuthorizedFinishBlock)_fail;#pragma mark - 推送通知权限+(BOOL)checkLocationAuthority;+(void)locationAuthorityCheckSuccess:(AuthorizedFinishBlock)_success fail:(AuthorizedFinishBlock)_fail;#pragma mark - 通讯录权限+(BOOL)checkAddressBookAuthority;+(void)AddressBookAuthorityCheckSuccess:(AuthorizedFinishBlock)_success fail:(AuthorizedFinishBlock)_fail;

下面是.m文件

里面引入了很多库文件，也不是所用项目都会用到的，用不到的注掉就好。

#import "LYAuthorizedMaster.h"#import        //摄像头麦克风 必须#import      //相册权限#import        //位置权限#import          //通讯录权限#import "AppDelegate.h"#define kAPPName [[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleName"]@implementation LYAuthorizedMaster#pragma mark -+(BOOL)checkAuthority:(AVAuthorizationStatus)_status{    return (_status == AVAuthorizationStatusAuthorized) || (_status == AVAuthorizationStatusNotDetermined);}+(void)showAlertController:(AuthorizedFinishBlock)_block device:(NSString *)_device{    UIAlertController *_alertC = [UIAlertController alertControllerWithTitle:@"没有权限" message:[NSString stringWithFormat:@"请开启‘%@’对 %@ 的使用权限",kAPPName,_device] preferredStyle:UIAlertControllerStyleAlert];    [_alertC addAction:[UIAlertAction actionWithTitle:@"取消" style:UIAlertActionStyleCancel handler:nil]];    [_alertC addAction:[UIAlertAction actionWithTitle:@"确定" style:UIAlertActionStyleDefault handler:^(UIAlertAction *action) {        [[UIApplication sharedApplication] openURL:[NSURL URLWithString:UIApplicationOpenSettingsURLString]];    }]];    [((AppDelegate *)[UIApplication sharedApplication].delegate).window.rootViewController presentViewController:_alertC animated:YES completion:_block];}#pragma mark - 摄像头权限+(BOOL)checkCameraAuthority{    return [self checkAuthority:[AVCaptureDevice authorizationStatusForMediaType:AVMediaTypeVideo]];}+(void)cameraAuthorityCheckSuccess:(AuthorizedFinishBlock)_success fail:(AuthorizedFinishBlock)_fail;{    if ([self checkCameraAuthority]) {        if (_success) {            _success();        }    }else{        [self showAlertController:_fail device:@"相机"];    }}#pragma mark - 麦克风权限+(BOOL)checkAudioAuthority{    return [self checkAuthority:[AVCaptureDevice authorizationStatusForMediaType:AVMediaTypeAudio]];}+(void)audioAuthorityCheckSuccess:(AuthorizedFinishBlock)_success fail:(AuthorizedFinishBlock)_fail{    if ([self checkAudioAuthority]) {        if (_success) {            _success();        }    }else{        [self showAlertController:_fail device:@"麦克风"];    }}#pragma mark - 相册权限+(BOOL)checkAlbumAuthority{    return [ALAssetsLibrary authorizationStatus] == ALAuthorizationStatusAuthorized;}+(void)albumAuthorityCheckSuccess:(AuthorizedFinishBlock)_success fail:(AuthorizedFinishBlock)_fail;{    if ([self checkAlbumAuthority]) {        if (_success) {            _success();        }    }else{        [self showAlertController:_fail device:@"照片"];    }}#pragma mark - 位置权限+(BOOL)checkLocationAuthority {    return [CLLocationManager locationServicesEnabled];}+(void)locationAuthorityCheckSuccess:(AuthorizedFinishBlock)_success fail:(AuthorizedFinishBlock)_fail{        if ([self checkLocationAuthority]) {        if (_success) {            _success();        }    }else{        [self showAlertController:_fail device:@"位置"];    }}#pragma mark - 推送通知权限+(BOOL)checkPushNotificationAuthority {    return [[UIApplication sharedApplication] currentUserNotificationSettings].types != UIUserNotificationTypeNone;}+(void)pushNotificationAuthorityCheckSuccess:(AuthorizedFinishBlock)_success fail:(AuthorizedFinishBlock)_fail{        if ([self checkAlbumAuthority]) {        if (_success) {            _success();        }    }else{        [self showAlertController:_fail device:@"通知"];    }}#pragma mark - 通讯录权限+(BOOL)checkAddressBookAuthority {    return ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusAuthorized || ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusNotDetermined;}+(void)AddressBookAuthorityCheckSuccess:(AuthorizedFinishBlock)_success fail:(AuthorizedFinishBlock)_fail{        if ([self checkAddressBookAuthority]) {        if (_success) {            _success();        }    }else{        [self showAlertController:_fail device:@"通讯录"];    }}

最后有些时会遇到不弹出权限提示，或需要在提示框增加详细描述的时候，需要手动在info.plist加一些字段。

NSLocationWhenInUseUsageDescription    位置权限 使用期间 状态

NSLocationAlwaysUsageDescription    位置权限 始终 状态

下面这些我并没有都试，所以也不知道是否正确....

NSLocationUsageDescription    用于访问位置权限

NSCalendarsUsageDescription    用于访问日历权限

NSContactsUsageDescription    用于访问联络人

NSPhotoLibraryUsageDescription    用于访问相册

NSRemindersUsageDescription    用于访问提醒
