Sorting Scenes in Xcode Interface Builder

由 ＊爱你＆永不变心＊ 提交于 2019-12-10 02:11:58
问题 So I'm not sure what to call it, but its that bar on the left in Storyboard Editor in Xcode that displays all of the different scenes. I love using storyboards, but my biggest pet peeve with them is that the scenes are organized in that list in an utterly random fashion. Every time I add a new view controller to the storyboard it gets inserted into a seemingly random place on the list. Two nearby views are not at all nearby in the scene listing. So my question is this: Is it possible to

Swift: Become First Responder on UITextField Not Working?

问题 I've created a custom UIViewController with one UITextField on Storyboard. On viewDidLoad , I set the UITextFIeld to becomeFirstResponder , nothing happened (no keyboards popped up).

It turns out none of the sub views are the first responder. My ViewController in

storyboard segue from a tablecell an its Detail Disclosure Button

由 余生颓废 提交于 2019-12-09 18:33:51
问题 I want to segue from a tablecell to two different viewcontrollers if clicked in the cell or clicked on the cells Detail Disclosure Button. If I ctrl-drag the second segue, the first is deleted. What am I doing wrong? Tnx Mica 回答1: I don't think you can link a specific detail disclosure button w/ a segue. My storyboards are extremely programatic b/c I use alot of custom CGRect etc.. so I tend to use something like this: -(void)tableView:(UITableView *)tableView
