How to link Table dataSource and delegate outlets to UITableViewController?

阅读更多关于 How to link Table dataSource and delegate outlets to UITableViewController?

问题 I'm new to Swift/iOS development. I have a UITableView in my storyboard that I want to populate with some data. In my attempt to do so, I created a class that inherits from UITableViewController . The implementation is not yet complete, but my understanding is that by inheriting from this class I can provide an IBOutlet to both dataSource and delegate . When I try to drag the outlet into the source file, I don't get the insertion point that I got when I tested this before. See image below:

Push View Controllers from Modal View in Storyboard

阅读更多关于 Push View Controllers from Modal View in Storyboard

I am using storyboard and have a screen which is presented modally, which I then need to push other view controllers from so that I can select items for the modal view (similar to adding an entry on the iPhone Calendar app).

How can I make this possible as I'm currently getting an error "Push segues can only be used when the source controller is managed by an instance of UINavigationController." Ah ok, so I now have it setup like you

How can I set the size of a UIView init with storyboard?

阅读更多关于 How can I set the size of a UIView init with storyboard?

I am currently using iOS 6.0. I have a custom UIView that needs to have a certain size. If I programmatically init the view and add it it's fine. However, I can't find a place where I can set the size of the view in the storyboard. Setting its size in the storyboard doesn't work because the storyboard thinks it's empty and set it's size to zero. Setting its size in viewDidLoad or viewDidAppear doesn't work because later on the size will be overwritten by _applyISEngineLayoutValue . You can do that in your Interface Builder. Open the storyboard where you have your view and open the utilities

What is the relationship between Storyboard form factor & Active Scheme in Xcode using Autolayout?

阅读更多关于 What is the relationship between Storyboard form factor & Active Scheme in Xcode using Autolayout?

I have a project in Xcode 5.0.1 targeting iOS7. I'm designing the app with a Storyboard, and I'm using Autolayout. When I build and run the app, I'm using the iOS Simulator to test it. I switch between the 3.5" and 4" retina schemes to view the app on different screen sizes. For the most part, everything works fine and Autolayout seems to work great. However, on one screen, there is a problem with the layout, but only under the following conditions: I set the scheme to "iPhone Retina (4-inch)" under iOS Simulator On the Storyboard, the form factor is set to "Retina 3.5-inch" In this case,

iOS 7 status and navigation bar different height in storyboard than in app

阅读更多关于 iOS 7 status and navigation bar different height in storyboard than in app

This is a view controller than is modally presented and therefore full screen. In the storyboard, the "top layout guide" is at y:64 . That is what I would expect when the status bar is height:20 and navigation bar is height:44 . However, when the app runs, the "top layout guide" is y:52 . I have no idea how or why it's losing 12 points. zinc1oxide When you use Apple's Navigation controller which inserts a navigation bar, it will have different heights based on your orientation. For example, the navigation bar is 44 points in portrait and 32 points in landscape. In your case, I'm guessing when
