问题 I am making an app that has about 20 different view controllers that are loaded into a single container view. Some of the views have sliders and buttons and some have only buttons. Is there a strategy I can use to make building the views controllers more inline with Objective C coding techniques? Currently I am trying to combine similar methods into model objects but before I get too involved I thought I'd ask if there is a better way. I'm also willing to do the groundwork and research so any

问题 This may be a strange problem and I hope someone has had it before. I added a SegmentControl to my TableView using this code: UIView *headerView = [[UIView alloc] init ]; [headerView addSubview:resultsSegment]; self.tableView.tableHeaderView = headerView; resultsSegment.frame = CGRectMake(45, 123, 250, 40); [self.tableView addSubview:resultsSegment]; With help from these forums the first three lines made the Segment part of the TableView Header so that it stayed in place for scrolling.

问题 My app supports iOS 6 to iOS 8 . It has non-renewing subscription feature with a restore button and recently I got a rejection on this: We found that your app is using Receipt Validation found in iOS 7+ to restore Non-Renewing Subscription .
