iOS-硬件授权检测【通讯录、相机、相册、日历、麦克风、定位授权】

总结下几个常用到的获取手机权限，从iOS8以后，获取手机某种权限需要在info.plist文件中添加权限的描述文件

    <key>NSContactsUsageDescription</key>
    <string>App需要您的允许,才能访问通讯录</string>
    <key>NSBluetoothPeripheralUsageDescription</key>
    <string>App需要您的允许,才能访问蓝牙</string>
    <key>NSCalendarsUsageDescription</key>
    <string>App需要您的允许,才能访问日历</string>
    <key>NSCameraUsageDescription</key>
    <string>App需要您的允许,才能访问相机</string>
    <key>NSHealthUpdateUsageDescription</key>
    <string>App需要您的允许,才能访问健康更新 </string>
    <key>NSLocationAlwaysUsageDescription</key>
    <string></string>
    <key>NSLocationUsageDescription</key>
    <string>App需要您的允许,才能访问位置</string>
    <key>NSLocationWhenInUseUsageDescription</key>
    <string></string>
    <key>NSMicrophoneUsageDescription</key>
    <string>App需要您的允许,才能访问麦克风</string>
    <key>NSMotionUsageDescription</key>
    <string>App需要您的允许,才能访问运动与健身</string>
    <key>NSPhotoLibraryUsageDescription</key>
    <string>App需要您的允许,才能访问相册</string>
    <key>NSRemindersUsageDescription</key>
    <string>App需要您的允许,才能访问提醒事项</string>

<!-- xcode9以后必须要加-->

<key>NSPhotoLibraryAddUsageDescription</key>

<string>App需要您的允许,才能访问相册</string>

1.通讯录

头文件

#import <AddressBook/AddressBook.h>

获取通讯录权限并请求授权

- (void)addressAuthorization{
    ABAuthorizationStatus authStatus = ABAddressBookGetAuthorizationStatus();
    if (authStatus == kABAuthorizationStatusNotDetermined) {
        // 请求授权
        ABAddressBookRef ressBookRef = ABAddressBookCreate();
        ABAddressBookRequestAccessWithCompletion(ressBookRef, ^(bool granted, CFErrorRef error) {
            if (granted) {
                NSLog(@"授权成功！");
            } else {
                NSLog(@"授权失败！");
            }
        });
    }
    else if(authStatus == kABAuthorizationStatusRestricted || authStatus == kABAuthorizationStatusDenied) {
        // 未授权

    }
    else{
        // 已授权
    }
}

2.相机

头文件

#import <AVFoundation/AVFoundation.h>
#import <AssetsLibrary/AssetsLibrary.h>

获取相机权限（直接跳相机，在跳到相机时，会提示是否允许访问相机）

- (void)cameraAuthorization{
    AVAuthorizationStatus authStatus = [AVCaptureDevice authorizationStatusForMediaType:AVMediaTypeVideo];
    if (authStatus == ALAuthorizationStatusDenied||authStatus == ALAuthorizationStatusRestricted) {
        NSLog(@"未授权！");
        return ;
    }
}

3.相册

头文件

#import <AVFoundation/AVFoundation.h>
#import <AssetsLibrary/AssetsLibrary.h>

获取相册权限（直接跳相册，在跳到相册时，会提示是否允许访问相册）

- (void)photoAuthorization{
    //判断是否已授权
    ALAuthorizationStatus authStatus = [ALAssetsLibrary authorizationStatus];
    if (authStatus == ALAuthorizationStatusDenied) {
        NSLog(@"未授权！");
        return;
    }
}

4.日历

头文件

#import <EventKit/EventKit.h>

获取日历权限并请求授权

-(void)calendarAuthorization{
    EKAuthorizationStatus authStatus = [EKEventStore authorizationStatusForEntityType:EKEntityTypeEvent];
    if (EKAuthorizationStatusNotDetermined == authStatus) {
        EKEventStore *event = [[EKEventStore alloc] init];
        //授权成功，执行后续操作
        [event requestAccessToEntityType:EKEntityTypeEvent completion:^(BOOL granted, NSError *error) {
            if (granted) {
                NSLog(@"授权成功！");
            } else {
                NSLog(@"授权失败！");
            }
        }];
    }
    else if(authStatus == EKAuthorizationStatusRestricted || authStatus == EKAuthorizationStatusDenied) {
        // 未授权

    }
    else{
        // 已授权
    }
}

5.麦克风

头文件

获取麦克风权限并请求授权

- (void)microphoneAuthorization{
    AVAuthorizationStatus authStatus = [AVCaptureDevice authorizationStatusForMediaType:AVMediaTypeAudio];
    if (authStatus == AVAuthorizationStatusNotDetermined) {// 未询问用户是否授权
        //第一次询问用户是否进行授权
        [[AVAudioSession sharedInstance] requestRecordPermission:^(BOOL granted) {
            if (granted) {
                 NSLog(@"授权成功！");
            }
            else {
                 NSLog(@"授权失败！");
            }
        }];
    }
    else if(authStatus == AVAuthorizationStatusRestricted || authStatus == AVAuthorizationStatusDenied) {
        // 未授权

    }
    else{
        // 已授权
    }
}

6.定位

头文件

#import <CoreLocation/CoreLocation.h>
#import <LocalAuthentication/LocalAuthentication.h>

获取定位权限（请求定位时，会提示是否允许访问位置）

- (void)locationAuthorization{
    CLAuthorizationStatus authStatus = [CLLocationManager  authorizationStatus];
    //第一次询问用户是否进行授权
    if (kCLAuthorizationStatusNotDetermined == authStatus) {
        //[[[CLLocationManager alloc] init] requestWhenInUseAuthorization];
        //开始定位用户的位置
        //[self.locMgr startUpdatingLocation];

    }
    else if(authStatus == kCLAuthorizationStatusRestricted || authStatus == kCLAuthorizationStatusDenied) {
        // 未授权
    }
    else{
        // 已授权
    }

}
