interface-builder

问题 I have this view controller, meant to present model object details in a generic way: class APIModelDetailsVC<T where T: APIModel>: UIViewController {...} I'd like my storyboard to use this class. I'm able to assign it in Interface Builder: I do the preparation of this ViewController in a tableview's didSelect method (including specifying the type for the generic placeholder): override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) { print(

问题 I have a menu with several items created in interface builder. It looks fine there and 'enabled' is checked. But when I run application, all menu items are grayed out. I've checked isEnabled , it returns true. Also, menu items created programmatically (with initWithTitle and without interface builder) work just fine. Am I missing something here? I'm really quite new to OSX development (in fact, this is my first day). Thank you 回答1: Remember to set your menu item's target and ensure that said

问题 When I am trying to set the width of a UIView to be proportional to the superview from storyboard the option is not showing up in Xcode 11. But in Xcode 10 it's showing the "Equal Widths" and "Equal Heights" option. 回答1: Works fine for me in Xcode 11.2: 来源： https://stackoverflow.com/questions/58683474/not-able-to-set-proportional-height-for-a-uiview-in-storyboard-in-xcode-11

问题 I created a UITableViewCell in Xcode 4 using IB. But for some weird reason when I trigger my edit button, the cell acts really weird and doesn't have the same animations as a normal table view cell. I don't know what is happening, I tried implementing -(void)setEditing:(BOOL)editing animated:(BOOL)animated in my custom cell class but still nothing works. UPDATE: My ViewController that I am using the cell in, has this code under cellForAtIndex to display the cell. CustomCell *cell =

问题 I used to use autolayout add new constraints to make simple constraints to superview / relative view like this (for loooong time): However, recently after updated to the latest xcode (11.3.3 or just 11.3/11C29), I have this weird issue: when I set the constant = 0, they always generate the constraints in an unwanted way like this: And it seems default value is somehow 20 and making my view look so wrong (0 compared to 20?) If I fix that by edit the constraint like this: Then it'll correct
