问题 I'm trying to filter a UITableView's data using a UISearchDisplayController and NSCompoundPredicate . I have a custom cell with 3 UILabels that I want to all be filtered within the search, hence the NSCompoundPredicate . // Filter the array using NSPredicate(s) NSPredicate *predicateName = [NSPredicate predicateWithFormat:@"SELF.productName contains[c] %@", searchText]; NSPredicate *predicateManufacturer = [NSPredicate predicateWithFormat:@"SELF.productManufacturer contains[c] %@", searchText

问题 I have a very basic UITableView with an attached UISearchBar, and here's the flow of what happens UITableView is empty, user taps UISearchBar, and brings up keyboard.

The problem is any subsequent search attempts. The same

问题 I'd like to create an UISearchBar function, which gets called like the search in the App Store: Execute the function (NSURLConnection) after a few seconds (NSTimer) the user did finish typing and just one time for this period. Does anyone have an idea? EDIT self.currentTaskID = self.currentTaskID + 1; NSInteger taskID = self.currentTaskID; dispatch_queue_t queue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0); dispatch_after(dispatch_time(DISPATCH_TIME_NOW, 1 * NSEC_PER_SEC),

Thanks. -Fernando Well, I made some changes but it is still not so good: -

问题 I have a UISearchBar that needs to be compressed (see screenshot) and then expand to a larger size when it is touched or isActive. How would I go about doing this? Currently my search bar is placed in the view via IB. thanks 回答1: I would suggest adding a NSNotifcation listener for the keyboard showing/hiding notifications and based on this adjust the UISearchBar frame: - (void)viewWillAppear:(BOOL)animated { [super viewWillAppear:animated]; NSNotificationCenter *nc = [NSNotificationCenter

问题 I need to make the table view inside the UISearchDisplayController class to be a custom class which extends from UITableView .
