AutoLayout: UIView within UIView has incorrect frame

阅读更多关于 AutoLayout: UIView within UIView has incorrect frame

问题 I am working with AutoLayout in Storyboard, and everything seemed to be going fine. However, when I put one UIView within another and apply all the constraints I want to both the container and its children, I notice that the frame is incorrect in viewDidLayoutSubviews: . Rather than being the frame I would expect to be calculated given my constraints, it is some disgustingly large frame (albeit at the correct origin). For example, rather than a frame of {{26, 10}, {444, 10}} I get something

Getting subViews' frames in Storyboard

阅读更多关于 Getting subViews' frames in Storyboard

I just want (for now) to get the dimensions of a subview on the view controller's instantiation. [This is a reduction to as simple a case I can find of a previous question . I am trying to figure out why subViews of scenes in Storyboards are not behaving the way I expect, which is to say: like XIBs do - I just want to get dimensions of my subviews before anything is actually drawn to the screen] To condense the problem down to a new, clean project, I do this: create a new, single view project with "using Storyboard" checked add a single UIView to the default existing MainStoryboard_iPad

Why isn't initWithCoder initializing items correctly?

阅读更多关于 Why isn't initWithCoder initializing items correctly?

问题 I've got a subclass of UITableViewCell . My subclass contains several UILabel s. I want my subclass to initialize these labels to some default settings that applies to every table view cell of mine. I read that I should be using initWithCoder for this. My initWithCoder function is being called, and I can step through each line in my function and it appears to go through the motions. When I run my application I do not see any of the properties being applied, though. Most noticeably, the font

iOS - best practice for managing code merge in a storyboard

阅读更多关于 iOS - best practice for managing code merge in a storyboard

问题 Merging in a xcode storyboard with many team members can produce many conflicts etc. I need a strategy to share a storyboard with 20 team members but to avoid the nightmares associated with merging code in a storyboard. I thought of having a separate target per team in xcode but this doesn't do well as we all need the updates so having two story boards is not good practice. my code base is inherited. its a forked project that is storyboard heavy already. I think changing to xib might be

Xcode Localization is driving me nuts! Not loading Storyboard

阅读更多关于 Xcode Localization is driving me nuts! Not loading Storyboard

问题 It's been 2 days this issue is driving me nuts. I'm trying to localize my iOS app but for the life of me I can't get it to work. It works easy enough when I try on a blank project but not on my current project. I've added the languages in the Localizations using "+", I've localized the storyboard but when I check on simulator or device I still see the english version. And in fact it's not even the English one because if I change the Maintsoryboard (english) I don't see the changes in the

阅读更多关于 Cannot Connect Storyboard Unwind Segue

问题 I am attempting to create an unwind segue but nothing will connect to it when ctrl+dragging. Also when I right click on the Exit icon there are no options available. Any ideas? 回答1: You need to have an IBAction defined on a view controller that takes an argument of type "UIStoryboardSegue *". Something like this: @interface MyViewController ... - (IBAction)unwindFromConfirmationForm:(UIStoryboardSegue *)segue { } ... @end Swift 3 Version @IBAction func unwindToViewController(segue:

Multiple views in Xcode storyboard view controller, one of them won't appear in storyboard editor

阅读更多关于 Multiple views in Xcode storyboard view controller, one of them won't appear in storyboard editor

I'm having trouble updating a project someone else created in Xcode. This is an app built in storyboard and in one case, there is a scene with a view controller that has multiple views underneath it in the document outline palette of the storyboard editor (shown in included image). The first view is the one that becomes highlighted in the storyboard editor when it is clicked on, and as you change the design or the objects in the view that view is updated. There is a second view (the one beneath exit and first responder) that is somehow attached to that scene but I cannot figure out how to edit
