UIImagePickerController
视图控制器,用于管理用于拍照、录制电影和从用户的媒体库中选择项的系统接口。
UIImagePickerController类只支持竖屏模式。这个类是按原样使用的,不支持子类化。这个类的视图层次结构是私有的,不能修改,只有一个例外。您可以将自定义视图分配给cameraOverlayView属性,并使用该视图来显示附加信息或管理相机接口和代码之间的交互。
获取、相册权限支持iOS8.0以上,导入需要的头文件以及Photos框架#import <Photos/Photos.h>
PHAuthorizationStatus authorStatus = [PHPhotoLibrary authorizationStatus];
if (authorStatus == PHAuthorizationStatusNotDetermined) {
//用户尚未对该应用程序做出选择
}else if (authorStatus == PHAuthorizationStatusRestricted){
//此应用程序未被授权访问照片数据。
//用户不能改变这个应用程序的状态,可能是由于活动的限制
NSLog(@"此应用程序未被授权访问照片数据。");
return;
}else if (authorStatus == PHAuthorizationStatusDenied){
//用户已明确拒绝此应用程序访问照片数据。
NSLog(@"用户已明确拒绝此应用程序访问照片数据。");
return;
}else if (authorStatus == PHAuthorizationStatusAuthorized){
//用户已授权此应用程序访问照片数据。
