iOS中获取相册、相机、定位、以及麦克风权限设置

1、判断用户是否获取了相册的访问权限

#import <AssetsLibrary/AssetsLibrary.h>// 获取相册权限- (void)getPhotoLibraryAuthor {    ALAuthorizationStatus status = [ALAssetsLibrary authorizationStatus];    if (status == ALAuthorizationStatusRestricted || status == ALAuthorizationStatusDenied) {        UIAlertController *alertVc = [UIAlertController alertControllerWithTitle:nil message:@"请开启相册权限\n 设置 -> 隐私 -> 照片" preferredStyle:UIAlertControllerStyleAlert];        [alertVc addAction:[UIAlertAction actionWithTitle:@"确定" style:UIAlertActionStyleDefault handler:nil]];        [self presentViewController:alertVc animated:YES completion:nil];    } else {        [self openPhotoLibrary];    }}

2、判断用户是否获取了相机的访问权限

#import <AVFoundation/AVMediaFormat.h>#import <AVFoundation/AVCaptureDevice.h>// 获取相机权限- (void)getCameraAuthor {    AVAuthorizationStatus status = [AVCaptureDevice authorizationStatusForMediaType:AVMediaTypeVideo];    if (status == AVAuthorizationStatusRestricted || status == AVAuthorizationStatusDenied) {        UIAlertController *alertVc = [UIAlertController alertControllerWithTitle:nil message:@"请开启相机访问权限\n 设置 -> 隐私 -> 相机" preferredStyle:UIAlertControllerStyleAlert];        [alertVc addAction:[UIAlertAction actionWithTitle:@"确定" style:UIAlertActionStyleDefault handler:nil]];        [self presentViewController:alertVc animated:YES completion:nil];    } else {        [self openCamera];    }}

3、判断用户是否获取了麦克风的访问权限

#import <AVFoundation/AVFoundation.h>- (BOOL)getMicrophoneAuthor {    __block BOOL canRecord = YES;    if ([self.audioSession respondsToSelector:@selector(requestRecordPermission:)]) {        [self.audioSession performSelector:@selector(requestRecordPermission:) withObject:^(BOOL granted) {            if (granted) {                canRecord = YES;            } else {                canRecord = NO;                UIAlertController *alertVc = [UIAlertController alertControllerWithTitle:nil message:@"请开启麦克风访问权限:\n设置 -> 隐私 -> 麦克风" preferredStyle:UIAlertControllerStyleAlert];        [alertVc addAction:[UIAlertAction actionWithTitle:@"确定" style:UIAlertActionStyleDefault handler:nil]];        [self presentViewController:alertVc animated:YES completion:nil];            }        }];    }    return canRecord;}

4、判断用户是否获取了定位的访问权限

//检测的是整个的iOS系统的定位服务是否开启[CLLocationManagerlocationServicesEnabled]//检测当前应用的定位服务是否开启需要通过一下方法来检测- (void)locationManager:(CLLocationManager*)managerdidFailWithError:(NSError*)error {        UIAlertController *alertVc = [UIAlertController alertControllerWithTitle:nil message:@"请开启定位权限:\n设置 -> 隐私 -> 定位服务" preferredStyle:UIAlertControllerStyleAlert];        [alertVc addAction:[UIAlertAction actionWithTitle:@"确定" style:UIAlertActionStyleDefault handler:nil]];        [self presentViewController:alertVc animated:YES completion:nil];}**或者是下面这个可以尝试一下：**- (void)getLocationAuthor {        CLAuthorizationStatus status = [CLLocationManager authorizationStatus];          if (status == kCLAuthorizationStatusDenied || status == kCLAuthorizationStatusRestricted) {          UIAlertController *alertVc = [UIAlertController alertControllerWithTitle:nil message:@"请开启定位权限:\n设置 -> 隐私 -> 定位服务" preferredStyle:UIAlertControllerStyleAlert];        [alertVc addAction:[UIAlertAction actionWithTitle:@"确定" style:UIAlertActionStyleDefault handler:nil]];        [self presentViewController:alertVc animated:YES completion:nil];      } }
