解决相机相册调用奔溃：

崩溃：[access] This app has crashed because it attempted to access
privacy-sensitive data without a usage description. The app’s
Info.plist must contain an NSPhotoLibraryUsageDescription key with a
string value explaining to the user how the app uses this data.

ios 10 中权限适配
升级到iOS10之后，需要设置权限的有：

<!-- 相册 -->   
<key>NSPhotoLibraryUsageDescription</key>   
<string>App需要您的同意,才能访问相册</string>   
<!-- 相机 -->   
<key>NSCameraUsageDescription</key>   
<string>App需要您的同意,才能访问相机</string>   
<!-- 麦克风 -->   
<key>NSMicrophoneUsageDescription</key>   
<string>App需要您的同意,才能访问麦克风</string>   
<!-- 位置 -->   
<key>NSLocationUsageDescription</key>   
<string>App需要您的同意,才能访问位置</string>   
<!-- 在使用期间访问位置 -->   
<key>NSLocationWhenInUseUsageDescription</key>   
<string>App需要您的同意,才能在使用期间访问位置</string>   
<!-- 始终访问位置 -->   
<key>NSLocationAlwaysUsageDescription</key>   
<string>App需要您的同意,才能始终访问位置</string>   
<!-- 日历 -->   
<key>NSCalendarsUsageDescription</key>   
<string>App需要您的同意,才能访问日历</string>   
<!-- 提醒事项 -->   
<key>NSRemindersUsageDescription</key>   
<string>App需要您的同意,才能访问提醒事项</string>   
<!-- 运动与健身 -->   
<key>NSMotionUsageDescription</key> <string>App需要您的同意,才能访问运动与健身</string>   
<!-- 健康更新 -->   
<key>NSHealthUpdateUsageDescription</key>   
<string>App需要您的同意,才能访问健康更新 </string>   
<!-- 健康分享 -->   
<key>NSHealthShareUsageDescription</key>   
<string>App需要您的同意,才能访问健康分享</string>   
<!-- 蓝牙 -->   
<key>NSBluetoothPeripheralUsageDescription</key>   
<string>App需要您的同意,才能访问蓝牙</string>   
<!-- 媒体资料库 -->   
<key>NSAppleMusicUsageDescription</key> 
 <string>App需要您的同意,才能访问媒体资料库</string>  

info.plist中根据自己的需求复制添加

在使用时 .m 中添加

//相机
#import <AVFoundation/AVCaptureDevice.h>
#import <AVFoundation/AVMediaFormat.h>
//相册
#import <AssetsLibrary/AssetsLibrary.h>

代码示例：
switch (buttonIndex) {
        case 1:
        {
            //相机权限
            AVAuthorizationStatus authStatus = [AVCaptureDevice authorizationStatusForMediaType:AVMediaTypeVideo];
            if (authStatus ==AVAuthorizationStatusRestricted ||//此应用程序没有被授权访问的照片数据。

                authStatus ==AVAuthorizationStatusDenied)  //用户已经明确否认了这一照片数据的应用程序访问
            {
                // 无权限 引导去开启
                NSURL *url = [NSURL URLWithString:UIApplicationOpenSettingsURLString];
                if ([[UIApplication sharedApplication]canOpenURL:url]) {
                    [[UIApplication sharedApplication]openURL:url];
                }
            }else{
                if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) {
                    [self loadImage:UIImagePickerControllerSourceTypeCamera];
                }
                else
                {
                    NSLog(@"手机不支持相机");
                }
            }
                    }
            break;
        case 2:
        {
            //相册权限
            ALAuthorizationStatus author = [ALAssetsLibrary authorizationStatus];
            if (author ==ALAuthorizationStatusRestricted || author ==ALAuthorizationStatusDenied){
                //无权限 引导去开启
                NSURL *url = [NSURL URLWithString:UIApplicationOpenSettingsURLString];
                if ([[UIApplication sharedApplication] canOpenURL:url]) {
                    [[UIApplication sharedApplication] openURL:url];
                }
            }else{
                if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypePhotoLibrary]) {
                    [self loadImage:UIImagePickerControllerSourceTypePhotoLibrary];
                }
                else
                {
                    NSLog(@"手机不支持相册");
                }
            }


        }
            break;

        default:
            break;
    }
