获取本地图片

获取本地图片使用UIImagePickerController

UIImagePickerController *picker = [[UIImagePickerController alloc] init];    picker.sourceType = 0;//这个表示想访问哪个相册，0表示显示所有的相册，其他的枚举值表示进入选择相片页面后是一个特定的相册    picker.delegate = self;    [self presentViewController:picker animated:YES completion:nil];

先要完成图片的选择，需要遵循两个代理UINavigationBarDelegate,UIImagePickerControllerDelegate

#pragma 实现选择图片代理方法- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary<NSString *,id> *)info{    NSLog(@"%@",info);    self.imageV.image = info[UIImagePickerControllerOriginalImage];    [self dismissViewControllerAnimated:YES completion:nil];}
