问题 In Xcode, whenever I see warnings (usually about misplaced elements) appear in the XIB / Storyboard, I have to: Select the container (Usually the containing view controller or the top most view) From the Xcode menu select Editor -> Resolve Auto Layout Issues -> All views in <container name> -> Appropriate action ( For instance: Update frames ) to resolve the issues. The above method takes requires steps and a bit time consuming to me. It would be great if I could: - Resolve all warnings for

问题 I have a UINavigationController in a storyboard which is not using AutoLayout. With the status bar visible the actual height of the UINavigationBar is 64.0 and yet when I log self.navigationBar.frame.size.height I get 44.0. How do I get the actual height of the UINavigationBar? I'm using Xcode 7.3 and the storyboard builds for iOS 6. 回答1: The height of the UINavigationBar is 44 . The reason you´re getting 64 is because of your status bar is visible and it has a height of 20 . Update: To

问题 In this screen shot you can see that I have added UITableView in UIViewController then customized the UITableViewCell by adding some labels in it. But the issue is when I run the application. All of the cells are empty. There are no labels at all. I am not getting what can be the issue.

Actually when you create a custom cell you have to do these things: Setup the

So I am going from: Navigation Controller > VC > Modal View Controller > ??? Here I want to push a VC so that I can select an item to return to the modal view. How can I make this possible as I'm currently getting an error "Push segues can only be used when the source

问题 EDIT Built a new sample project from scratch and the dynamic tableview cell height is working flawlessly. I then tried to replicate by trimming down my project to it's bare minimum and it's STILL broken (first few cells buggy). Attaching full project for both working and not working examples. Project/code literally looks 99% identical and for the love of me can't figure out where the 1% difference is. The only thing that is popping out at me is that I used different size classes (wAny hAny vs

问题 I need to design the view like below image and I have tried with fixed heights and also tried compact width and regular height and regular width and compact height but those scenarios did not worked for me. How can i set View height as percentage of the screen height in Storyboards? I'm using Xcode 7 回答1: Basically you need to act on the multiplier property of an height equal constraint. To do that while pressing CTRL, drag from the view to its superview and select equal heights constraint ,

问题 Every time when I merge other team member's iOS objc project, I got some strange conflict like this: <<<<<<< HEAD <rect key="frame" x="254.00000003476939" y="0.0" width="63" height="21"/> ======= <rect key="frame" x="254.00000010362709" y="0.0" width="63" height="21"/> >>>>>>> XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX We never change the value of x, and we always give integer like value. Obviously, Xcode changed the value automatically. How to prevent this kind things happen? 回答1: You could

问题 In Attributes inspector there is an option Installed . I am unsure of it's meaning. Does it mean that the element will be present in any size class? 回答1: It is for adding that specific view to the corresponding size class.

You can check more about this option in Enable And Disable Views. 来源： https://stackoverflow.com/questions/33975427/installed-option-in-attributes-inspector

问题 I am setting up my UITableView using storyboard editor. For creating my cells I am using the standard delegate method: - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"SearchResultCell"]; if (cell == nil) { // Do cell setup } // etc return cell; } Except when the cell is dequeued the very first time it's not nil, as it should be. So the code inside the if statement is
