iOS隐私权限配置

1. 首先引入相关头文件

#import <AVFoundation/AVFoundation.h> // 麦克风、相机
#import <Photos/Photos.h> // 相机、相册
#import <CoreLocation/CoreLocation.h>  // 定位
#import <CoreBluetooth/CoreBluetooth.h> // 蓝牙

2. plist文件添加key

<key>NSMicrophoneUsageDescription</key>
<string>开启麦克风权限</string>
<key>NSCameraUsageDescription</key>
<string>开启相机权限</string>
<key>NSPhotoLibraryUsageDescription</key>
<string>开启相册权限</string>
<key>NSLocationUsageDescription</key>
<string>开启位置权限</string>
<key>NSLocationWhenInUseUsageDescription</key>
<string>使用期间开启位置权限</string>
<key>NSLocationAlwaysUsageDescription</key>
<string>始终开启位置权限</string>

3. 麦克风权限

// 获取麦克风权限状态
- (BOOL)getMicrophonePermissionStatus
{
    AVAuthorizationStatus microPhoneStatus = [AVCaptureDevice authorizationStatusForMediaType:AVMediaTypeAudio];
    if (microPhoneStatus <= 2) {
        // 未授权 or 被拒绝
        return NO;
    }
    return YES;
}
// 开启麦克风权限
- (void)openMicrophonePermissionMethod
{
    AVAuthorizationStatus microPhoneStatus = [AVCaptureDevice authorizationStatusForMediaType:AVMediaTypeAudio];
    switch (microPhoneStatus) {
        case AVAuthorizationStatusNotDetermined:
        { // 未授权
            [AVCaptureDevice requestAccessForMediaType:AVMediaTypeAudio completionHandler:^(BOOL granted) {
                NSLog(@"麦克风权限开启结果 --- %d", granted);
            }];
        }
            break;
        case AVAuthorizationStatusDenied:
        case AVAuthorizationStatusRestricted:
        {
            // 被拒绝 --- 跳转APP设置页
        }
            break;
        case AVAuthorizationStatusAuthorized:
        { 
            // 有授权 --- 跳转APP设置页
        }
            break;
            
        default:
            break;
    }
}

4. 相机权限

// 获取相机权限状态
- (BOOL)getCameraPermissionStatus
{
    AVAuthorizationStatus status = [AVCaptureDevice authorizationStatusForMediaType:AVMediaTypeVideo];
    if (status <= 2) {
        return NO;
    }
    return YES;
}
// 开启相机权限
- (void)openCameraPermissionMethod
{
    AVAuthorizationStatus status = [AVCaptureDevice authorizationStatusForMediaType:AVMediaTypeVideo];
    switch (status) {
        case AVAuthorizationStatusNotDetermined:
        { // 未授权
            [AVCaptureDevice requestAccessForMediaType:AVMediaTypeVideo completionHandler:^(BOOL granted) {
                NSLog(@"相机权限开启状态 --- %d", granted);
            }];
        }
            break;
        case AVAuthorizationStatusRestricted:
        case AVAuthorizationStatusDenied:
        { // 被拒绝 --- 跳转APP设置页
        }
            break;
        case AVAuthorizationStatusAuthorized:
        { // 已授权 --- 跳转APP设置页
        }
            break;
            
        default:
            break;
    }
}

5. 相册权限

// 获取相册权限状态
- (BOOL)getAlbumPermissionStatus
{
    if (@available(iOS 14.0, *)) {
        PHAuthorizationStatus status = [PHPhotoLibrary authorizationStatusForAccessLevel:(PHAccessLevelReadWrite)];
        if (status <= 2) { // 未授权 or 被拒绝
            return NO;
        }
    }
    else {
        PHAuthorizationStatus status = [PHPhotoLibrary authorizationStatus];
        if (status <= 2) { // 未授权 or 被拒绝
            return NO;
        }
    }
    return YES;
}
// 开启相册权限
- (void)openAlbumPermissionMethod
{
    PHAuthorizationStatus status = [PHPhotoLibrary authorizationStatus];
    switch (status) {
        case AVAuthorizationStatusNotDetermined:
        { // 未授权
            if (@available(iOS 14.0, *)) {
                [PHPhotoLibrary requestAuthorizationForAccessLevel:(PHAccessLevelReadWrite) handler:^(PHAuthorizationStatus status) {
                    NSLog(@"ios14以上 - 相册权限开启结果 --- %ld", (long)status);
                }];
            }
            else {
                [PHPhotoLibrary requestAuthorization:^(PHAuthorizationStatus status) {
                    NSLog(@"ios14以下 - 相册权限开启结果 --- %ld", (long)status);
                }];
            }
        }
            break;
        case AVAuthorizationStatusRestricted:
        case AVAuthorizationStatusDenied:
        {  
            // 被拒绝 --- 跳转APP设置页
        }
            break;
        case AVAuthorizationStatusAuthorized:
        { 
            // 已授权 --- 跳转APP设置页
        }
            break;
            
        default:
            break;
    }
}

6. 定位权限

@interface ViewController ()<CLLocationManagerDelegate>
@property (nonatomic, strong) CLLocationManager *locationManager;
@end

@implementation ViewController
// 获取定位权限状态
- (BOOL)getLocationPermissionStatus
{
    CLAuthorizationStatus locationStatus = [CLLocationManager authorizationStatus];
    if ([CLLocationManager locationServicesEnabled] && locationStatus > 2) {
        return YES;
    }
    return NO;
}
// 开启定位权限
- (void)openLocationPermissionMethod
{
    CLAuthorizationStatus locationStatus = [CLLocationManager authorizationStatus];
    if (locationStatus == kCLAuthorizationStatusNotDetermined) {
        // 未授权
        [self.locationManager requestWhenInUseAuthorization];
    }
    else {
       // 被拒绝 or 已授权  --- 跳转APP设置页
    }
}

- (void)locationManager:(CLLocationManager *)manager didChangeAuthorizationStatus:(CLAuthorizationStatus)status
{
    NSLog(@"locationManager --- %d", status);
}

- (CLLocationManager *)locationManager
{
    if (!_locationManager) {
        _locationManager = [[CLLocationManager alloc] init];
        _locationManager.delegate = self;
    }
    return _locationManager;
}
@end
