1. 判断访问相册或相机权限是否开启

//在info.plist 里面设置

Privacy – Camera Usage Description App需要您的同意,才能访问相
Privacy – Photo Library Usage Description App需要您的同意,才能访问相册

科普：

相册

//相册权限判断需要引入框架

#import <Photos/PHPhotoLibrary.h>  //相册

PHAuthorizationStatus相册权限状态判断
在8.0系统以后，新加入了Photos.framework框架，我们可以利用框架中的PHAuthorizationStatus进行相册权限状态判断。

判断是否开启相册权限的4中状态

typedef NS_ENUM(NSInteger,PHAuthorizationStatus) { 

       //1. 用户还没有关于这个应用程序做出了选择 
        PHAuthorizationStatusNotDetermined = 0, 

        //2. 这个应用程序未被授权访问图片数据。用户不能更改该应用程序的状态,可能是由于活动的限制,如家长控制到位。   
        PHAuthorizationStatusRestricted, 

       //3. 用户已经明确否认了这个应用程序访问图片数据  
        PHAuthorizationStatusDenied,

       //4. 用户授权此应用程序访问图片数据  
        PHAuthorizationStatusAuthorized

    }PHOTOS_AVAILABLE_IOS_TVOS(8_0, 10_0);

相机

//相册权限判断需要引入框架

#import <AVFoundation/AVCaptureDevice.h>
#import <AVFoundation/AVMediaFormat.h>

判断是否开启相机权限的4中状态

typedef NS_ENUM(NSInteger, AVAuthorizationStatus) {  

//1. 表明用户尚未选择关于客户端是否可以访问硬件   
  AVAuthorizationStatusNotDetermined = 0,  

//2. 客户端未被授权访问硬件的媒体类型。用户不能改变客户机的状态,可能由于活跃的限制,如家长控制  
  AVAuthorizationStatusRestricted,  

//3. 明确拒绝用户访问硬件支持的媒体类型的客户
   AVAuthorizationStatusDenied, 

//4. 客户端授权访问硬件支持的媒体类型
   AVAuthorizationStatusAuthorized 

} NS_AVAILABLE_IOS(7_0) __TVOS_PROHIBITED;

=================使用====================

//选择从相册获取图片
//判断状态  如果已经授权 则从相册选取相片 
         如果没有授权  则跳转到授权设置界面
//选择从相机获取图片
//判断状态  如果已经授权 则打开摄像头 
         如果没有授权  则跳转到授权设置界面


//引入下面的框架

 //自定义的枚举
typedef NS_ENUM(NSInteger, ChosePhontType) {

    ChosePhontTypeAlbum,  //相册

    ChosePhontTypeCamera   //相机

};

//下面部分可以直接粘贴复制使用

        }

    }

    #pragma mark UIImagePickerController回调方法================

    - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info { //选取的照片

        //选取的照片
        UIImage *image = info[UIImagePickerControllerEditedImage];

    }

    - (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker { //取消选择
        [self dismissViewControllerAnimated:YES completion:nil];
    }

2 、定位

=======检测是否开启定位======
在info.plist 里面配置

Privacy - Location When In Use Usage Description    App需要使用定位功能
Privacy - Location Always Usage Description     App需要使用定位功能

引入框架

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

遵循协议 <CLLocationManagerDelegate>

typedef NS_ENUM(int, CLAuthorizationStatus) {

        //定位服务授权状态是用户没有决定是否使用定位服务
        kCLAuthorizationStatusNotDetermined = 0,

        //定位服务授权状态是受限制的。可能是由于活动限制定位服务，用户不能改变。这个状态可能不是用户拒绝的定位服务
        kCLAuthorizationStatusRestricted,

        //定位服务授权状态已经被用户明确禁止，或者在设置里的定位服务中关闭
        kCLAuthorizationStatusDenied,

       //定位服务授权状态已经被用户允许在任何状态下获取位置信息。包括监测区域、访问区域、或者在有显著的位置变化的时候
        kCLAuthorizationStatusAuthorizedAlways NS_ENUM_AVAILABLE(10_12, 8_0),

       //定位服务授权状态仅被允许在使用应用程序的时候
        kCLAuthorizationStatusAuthorizedWhenInUse NS_ENUM_AVAILABLE(NA, 8_0),

};

【注意】

    //1.
    //判断定位是否开启是判断的整个手机系统的定位是否打开,并不是针对这一应用
    [CLLocationManager locationServicesEnabled]
    //跳转到  整个手机系统的“定位”设置界面
    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"prefs:root=LOCATION_SERVICES"]];

    //2.
    //跳转至 系统的权限设置界面
    NSURL *settingsURL = [NSURL URLWithString:UIApplicationOpenSettingsURLString];
    [[UIApplication sharedApplication] openURL:settingsURL];

=================使用=================

引入框架

    }

}

#pragma mark CoreLocation delegate----- 定位----

//定位失败则执行此代理方法

//定位失败弹出提示框,点击"打开定位"按钮,会打开系统的设置,提示打开定位服务

- (void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error {

    UIAlertController * alertVC = [UIAlertController alertControllerWithTitle:@"允许\"定位\"提示" message:@"请在设置中打开定位" preferredStyle:UIAlertControllerStyleAlert];

    UIAlertAction * ok = [UIAlertAction actionWithTitle:@"打开定位" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {

        //打开app定位设置

}

//定位成功

- (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray<CLLocation *> *)locations {

    //

    [locationManager stopUpdatingLocation];

    CLLocation *currentLocation = [locations lastObject];

    CLGeocoder * geoCoder = [[CLGeocoder alloc] init];

    //反编码

    [geoCoder reverseGeocodeLocation:currentLocation completionHandler:^(NSArray<CLPlacemark *> * _Nullable placemarks, NSError * _Nullable error) {

        if (placemarks.count > 0) {

            CLPlacemark *placeMark = placemarks[0];

            currentCity = placeMark.locality;

            if (!currentCity) {

                currentCity = @"无法定位当前城市";

            }

            NSLog(@"%@",currentCity); //这就是当前的城市

            NSLog(@"%@",placeMark.name);//具体地址:  xx市xx区xx街道

            //administrativeArea   省

            NSLog(@"%@",placeMark.administrativeArea);

        }

        else if (error == nil && placemarks.count == 0) {

            NSLog(@"No location and error return");
