UnityNativeGallery插件遇到红色问号

最近要用unity 获取相册照片遇到一个问题，貌似有些照片 显示红色问号，只有在iOS 上
会出现，安卓则正常，猜测iOS 对某些图片(png)的解析失败，为了解决这个问题，把拉起来的图片
格式统一改成了 jpg ,改了NativeGallery 这个 .mm 文件的代码，就是传给C# 的时候，改一下
1、大概一千零几行代码左右
改之前 ：

dispatch_group_notify( group, dispatch_get_main_queue(),
^{
	if( !pickingMultipleFiles )
		UnitySendMessage( "NGMediaReceiveCallbackiOS", "OnMediaReceived", [self getCString:resultPaths[0]] );
	else
		UnitySendMessage( "NGMediaReceiveCallbackiOS", "OnMultipleMediaReceived", [self getCString:[resultPaths componentsJoinedByString:@">"]] );
});

改之后 ：

dispatch_group_notify( group, dispatch_get_main_queue(),
	^{
        if( !pickingMultipleFiles )
        {
            NSData *imageData = [NSData dataWithContentsOfFile:resultPaths[0]];
            UIImage *originImage = [UIImage imageWithData:imageData];
            NSData *newIgdata= UIImageJPEGRepresentation(originImage, 1);
            [newIgdata writeToFile:resultPaths[0] atomically:YES];
            UnitySendMessage( "NGMediaReceiveCallbackiOS", "OnMediaReceived", [self getCString:resultPaths[0]] );
        }
			
		else
			UnitySendMessage( "NGMediaReceiveCallbackiOS", "OnMultipleMediaReceived", [self getCString:[resultPaths componentsJoinedByString:@">"]] );
	});

2、还有一处 七百多行
改之前 ：

	popup = nil;
imagePicker = nil;
imagePickerState = 2;
UnitySendMessage( "NGMediaReceiveCallbackiOS", "OnMediaReceived", [self getCString:resultPath] );
[picker dismissViewControllerAnimated:NO completion:nil];

改之后 ：

popup = nil;
imagePicker = nil;
imagePickerState = 2;
 NSData *imageData = [NSData dataWithContentsOfFile:resultPath];
 UIImage *originImage = [UIImage imageWithData:imageData];
 NSData *newIgdata= UIImageJPEGRepresentation(originImage, 1);
 [newIgdata writeToFile:resultPath atomically:YES];
 UnitySendMessage( "NGMediaReceiveCallbackiOS", "OnMediaReceived", [self getCString:resultPath] );
[picker dismissViewControllerAnimated:NO completion:nil];

OK，就这两处就可以了
