问题 I put a textfield in every cell of the table. And after editing the textfield, an EditingDidEnd Event will trigger. In the method of hanlding this event I try to use [XXXUITableViewController.tableView reloadData]; but it doesn't work(the delegate method is not called). If I try to reloadData in someway like hanlding Tapgesture, it works just fine. I can use anthoer way to make my app work, but it's better to know why is reloadData not working. Any ideas, thanks a lot. - (UITableViewCell *

问题 I'm developing a WatchKit app for the Apple Watch. I "finished" the app originally when the first beta was out back in Nov/Dec. I recently upgraded the the final release and somethings in WatchKit changed (as to be expected). I had to fix couple lines of code here and there since they changed how the app views start up. Anyway, after fixing the issues I noticed that my WKInterfaceTable displays and scrolls almost correctly. The last row in the table gets cut off (as indicated in the

问题 This question already has answers here : why storyboard ui elements not showing on UIViewController in xcode 6? (5 answers) Closed 4 years ago . I have made a storyboard using "wCompact" (Compact Width) and "hRegular" (Regular Height") size class. Now when I change to "wAny"|"wHeight" all the components of on the storyboard to be specific that view controller disappears. I want to copy the same design for "wAny" (Any Width) and hAny ("Any Height") size class. How can I do it ? Right now I

问题 I manually added UITabbarController in storyboard which is not root view controller. I added tabbar items to it and set segue relationships. I also set image and title of each tabbar item in code when the first view controller of UITabbarController is about to be presented but no matter what I do only the first item's image is visible. Other items images become visible only when they are tapped and their views are actually loaded. Any inputs how to fix it ? - (void)prepareForSegue:

问题 I've been searching on how to resize the tab bar items on the "Tab Bar Controller," but obviously couldn't find anything. The reason why I want to do this is because I have exactly 6 items, and it causes the "more" item to be created whenever you have 6 or more. So 4 items show up on the bottom and a "more" item that shows the other two items when clicked. My title for all my items are short, so I want to squeeze 6 of them right below without the "more" and the only way to do that is to

问题 I know how to set UIPanGesture events and recognizers and get the data I need when I create them programatically. However I am trying to learn how to work with the storyboard and use IBOutlets. I have dragged over an IBAction for 'Touch Drag Inside'. @IBAction func dragButtonDragEvent(sender: AnyObject) { println(sender) } The problem is the sender object I get is just the button itself. Is there a way to get the drag distance or drag event data when using an IBAction? I tried @IBAction func

问题 Using text view in storyboard you can make it not editable or not selectable next to Behavior caption or vice versa: Seems options looks very promising and it works good for editable option. But when I uncheck selectable checkbox it cause some issues with font and text in runtime. So let's say that I set font to Helvetica-Bold and set color Red (which are not default settings for text view) and then uncheck selectable box like on image above. Next let me add some code to viewDidLoad: self

问题 Is there a way to use UISearchController in a way that lets me storyboard the UISearchBar ? I have a storyboarded UI with a navigation bar which contains my search bar. It would be great if I could keep it this way because setting up the layout programmatically would be really inconvenient. I know the old UISearchDisplayController could be storyboarded. Is there a way to do something similar with UISearchController? 回答1: Add a UIView to your layout. That will be the container for your

问题 I'm hitting issues when attempting to design a UIToolbar Accessory View via an Xcode Storyboard. When I drag a UIToolbar object to the top margin of my View Controller, the item is added to the left pane and I am able to connect it to my class's IBOutlets. It appears correctly when I run the app. However, the toolbar is not visible anywhere on the storyboard. I thus lose the visual editing benefits of using Interface Builder in the first place. The bar button items are only visible in the
