问题 If a user decides to not allow an app to access cellular data every time they try to open the app they are shown a warning telling them that cellular data is turned off. Is there a way in the SDK to stop showing this message or control when / where it is displayed? 回答1: The system will show this message if you try to access the Internet when permission has been revoked. To prevent it from appearing, you could use Apple's Reachability code to detect network availability, and only make web

问题 I have a screen with an UISearchBar within my app. It might be that there is already text in the searchbar, when the user enters the screen. If the user then taps into the field and then taps cancel, the content of the searchbar should not be cleared. Is this achievable?

My code looks like this: -(void)initializeLocationServices { NSLog(@"Started location services"); locationManager = [

问题 I have a UITableView and have seen this effect and would like to implement it for our the followind data: menu_header menu_subheader * item * item menu_subheader * item * item * item Basically, I would like to show just the header and subeaders and then when the user clicks one of the subheaders, it displays the items (preferably in an animation block) AND adjusts the other cells down or up appropriately. Like this: Is there a prebuilt component that does this? Thinking about it, it seems

问题 I'm targeting iOS7 only. I want to 'resize' a UITextView when the keyboard is shown, so that all of the text can be seen, rather than being hidden behind the keyboard. I've considered a few different approaches to this... 1) Change the frame of the UITextView when the keyboard shows. The following question details the same problem that I have with this approach - despite the frame being set correctly, the last line/cursor will extend beyond the bounds of the UITextView , and therefore be out

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 6 years ago . I've seen online rumors from before iOS7's release about keyboards opening up. I haven't found anything in the documentation.
