1.通訊錄

頭文件

#import <AddressBook/AddressBook.h>

獲取通訊錄許可權並請求授權

- (void)addressAuthorization{
    ABAuthorizationStatus authStatus = ABAddressBookGetAuthorizationStatus();
    if (authStatus == kABAuthorizationStatusNotDetermined) {
        // 請求授權
        ABAddressBookRef ressBookRef = ABAddressBookCreate();
        ABAddressBookRequestAccessWithCompletion(ressBookRef, ^(bool granted, CFErrorRef error) {
            if (granted) {
                NSLog(@"授權成功！");
            } else {
                NSLog(@"授權失敗！");
            }
        });
    }
    else if(authStatus == kABAuthorizationStatusRestricted || authStatus == kABAuthorizationStatusDenied) {
        // 未授權
        
    }
    else{
        // 已授權
    }
}

2.相機

頭文件

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

獲取相機許可權（直接跳相機，在跳到相機時，會提示是否允許訪問相機）

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

3.相冊

頭文件

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

獲取相冊許可權（直接跳相冊，在跳到相冊時，會提示是否允許訪問相冊）

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

4.日曆

頭文件

#import <EventKit/EventKit.h>

獲取日曆許可權並請求授權

-(void)calendarAuthorization{
    EKAuthorizationStatus authStatus = [EKEventStore authorizationStatusForEntityType:EKEntityTypeEvent];
    if (EKAuthorizationStatusNotDetermined == authStatus) {
        EKEventStore *event = [[EKEventStore alloc] init];
        //授權成功，執行後續操作
        [event requestAccessToEntityType:EKEntityTypeEvent completion:^(BOOL granted, NSError *error) {
            if (granted) {
                NSLog(@"授權成功！");
            } else {
                NSLog(@"授權失敗！");
            }
        }];
    }
    else if(authStatus == EKAuthorizationStatusRestricted || authStatus == EKAuthorizationStatusDenied) {
        // 未授權
        
    }
    else{
        // 已授權
    }
}

5.麥克風

頭文件

獲取麥克風許可權並請求授權

- (void)microphoneAuthorization{
    AVAuthorizationStatus authStatus = [AVCaptureDevice authorizationStatusForMediaType:AVMediaTypeAudio];
    if (authStatus == AVAuthorizationStatusNotDetermined) {// 未詢問用戶是否授權
        //第一次詢問用戶是否進行授權
        [[AVAudioSession sharedInstance] requestRecordPermission:^(BOOL granted) {
            if (granted) {
                 NSLog(@"授權成功！");
            }
            else {

            }
        }];
    }
    else if(authStatus == AVAuthorizationStatusRestricted || authStatus == AVAuthorizationStatusDenied) {
        // 未授權
       
    }
    else{
        // 已授權
    }
}

6.定位

頭文件

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

獲取定位許可權（請求定位時，會提示是否允許訪問位置）

- (void)locationAuthorization{
    CLAuthorizationStatus authStatus = [CLLocationManager  authorizationStatus];
    //第一次詢問用戶是否進行授權
    if (kCLAuthorizationStatusNotDetermined == authStatus) {
        //[[[CLLocationManager alloc] init] requestWhenInUseAuthorization];
        //開始定位用戶的位置
        //[self.locMgr startUpdatingLocation];

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