问题 I was trying to use the new ios7 background transfer api to upload some photos to a server. what it happened now is 1) we upload the bytes to s3 2) call a service api to 'complete' the upload i looked at this doc and it seems background NSURLSession doesn't support 'data' task. does that mean i can't do the step 2 in background after the actual upload is done? 回答1: If you want a simpler solution than repurposing NSURLSessionDownloadTask for your "completed" API call, you can round trip a

问题 I have a UITableView where, in ios6, my custom cell stretched completely to the left and right sides of the screen. So my square image on the left of the cell was hard up against the phone screen. However, now in ios7, there is a small gap appearing on the left hand side so the image is now away from the side and slightly overlaps my text within the cell.

问题 I've tried to set the Alamofire.Manager.sharedInstance.session.configuration.HTTPAdditionalHeaders with my custom HTTP Headers in iOS 7 but I have had no luck. This works fine in iOS 8.
