I've got upload and listFolder working fine but just can't seem to get download to work. If I use downloadData, it succeeds but the fileContents NSData is 'nil'!
Code:
[[[[self client].filesRoutes downloadData:@"/hello.txt"]
setResponseBlock:^(DBFILESFileMetadata *result, DBFILESDownloadError *routeError, DBRequestError *networkError, NSData *fileContents) {
if (result) {
NSLog(@"%@\n", result);
[[Common sharedInstance].fileMgr removeItemAtPath:localPath error:nil];
if (!fileContents) {
NSLog(@"fileContents == nil!");
}
else if ([[Common sharedInstance].fileMgr createFileAtPath:localPath contents:fileContents attributes:nil]) {
NSLog(@"%@ created\n", localPath);
} else {
NSLog(@"%@ failed to create\n", localPath);
}
} else {
NSLog(@"DropBoxDataItem -loadFileToPath %@ failed: %@/%@", localPath, routeError, networkError);
}
}] setProgressBlock:^(int64_t bytesDownloaded, int64_t totalBytesDownloaded, int64_t totalBytesExpectedToDownload) {
NSLog(@"totalBytesDownloaded:%lld totalBytesExpectedToDownload:%lld\n", totalBytesDownloaded, totalBytesExpectedToDownload);
}];
Test File:
1. hello
2. world

If I try to use downloadUrl, I get the following error:

}];The output 'tmp' folder exists so the problem must be in the temp file where the SDK initially downloaded the data. Given my experience using downloadData, I'm not surprised there is something wrong with the temp file.
What could be causing these issues with just downloading?
Thx,
Pete
