需要注意的 几个点 :
- 属性 可以是在 C中 也可以在 V 中 V中的话 就 在 中 再给个 属性 就好了
- info 配置 问题 ：
NSContactsUsageDescription -> 通讯录
NSMicrophoneUsageDescription -> 麦克风
NSPhotoLibraryUsageDescription -> 相册
NSCameraUsageDescription -> 相机
NSLocationAlwaysUsageDescription -> 地理位置
NSLocationWhenInUseUsageDescription -> 地理位置
- 需要实现的 四个 协议 ：
<UIActionSheetDelegate,UIGestureRecognizerDelegate,UIImagePickerControllerDelegate,UINavigationControllerDelegate>
接下来 我就直接 上代码了

// 头像选取之后的 替换保存
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary<NSString *,id> *)info{
