问题是我能用AssetLibrary获得图像,
首先我用iPhone的应用程序相机拍照, 然后编辑照片,剪下来。
在我的应用程序中,我想得到经过编辑的图像。
如果我使用 UIImaage Picker 主计长代表方法
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingImage:(UIImage *)image editingInfo:(NSDictionary *)editingInfo
我可以用图像获得经过编辑的图像。
但如果我用这个方法
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
并使用该信息获取参考URL,
我可以用 AssetLibrary 来获得图像。
关键在于图像总是编辑前的原始图像, 而不是我编辑的图像 。
您可以这样编辑图像-
UIImage* image = [info objectForKey:UIImagePickerControllerEditedImage];
