> Hello Cordova Team,
> we needed to download big files (>2GB) via FileTransfer and use the onProgressEvent
to display the progress.
> On Android everything is fine. On iOS the reported sizes in the onProgressEvent are not
valid, if the downloaded file is larger than 2GB:
> {{CDVFileTransfer}} uses {{NSInteger}} for {{bytesTransfered}} and {{bytesExpected}}.
{{NSInteger}} only is up to 2G-1 as mentioned here: http://stackoverflow.com/questions/2107544/types-in-objective-c-on-iphone
> We patched the library files {{CDVFileTransfer.h}} and {{CDVFileTransfer.m}} of version
2.9.0 to use "unsigned long long" - now we are able to display downloads up to 16Exabytes-1byte
correctly. We can see in github, that version 3.0.0 has the same issue.
> I will add the diff in the issue after creating it.
