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 . However, since your Application supports iOS 6.0 , Non-Renewing Subscription cannot be restored in this manner. It would be appropriate to remove this feature from you binary and include an optional user registration feature, to deliver subscription

问题 Can i adjust RMMarker to user's current location using MBTiles without tapping on map? Is there any method or API to achieve this in mapbox without WiFi/3G?

问题 I create a new window when there is an additional screen (up to 2). Each window shows a different content, in a different screen. The problem is under iOS7: Creating and showing this external window makes the status bar visible in the first one, which is also the main one. Then, the system adds some space (20points) to rearrange the top bar and some views. It does not work for me, because it's a custom bar. Why is this happening and how may I stop the system to add the status bar? This is the

问题 Starting from iOS 7.1 , I have not been able to read the text nor set the placeholder of UISearchBar. The text property always returns nil and the search bar is always a blank white rectangle. In iOS 7.0 and below, I had no such problems. Does 7.1 require me to treat UISearchBars differently to make text and placeholder work? - (void)viewDidLoad { [super viewDidLoad]; self.searchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(0.0, 0.0, 320.0, 44.0)]; self.searchBar.placeholder = @
