Not able to set proportional height for a UIView in storyboard in Xcode 11

由 会有一股神秘感。 提交于 2020-03-04 23:07:25
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

Xcode 11 add new constraints set zero: use set value instead of default / standard

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

Draw custom separator line between UITableViewCell on iOS 7

问题 Because I had some troubles using the default separator line between the UITableViewCell I want to use my own. Therefore I'm using auto layout. C# is the language I used. You can of course provide solutions in Objective-C. In the constructor of my custom cell I add my view UIView : separator = new DividerView (); ContentView.Superview.AddSubview (separator); One has to add it to the superview otherwise it doesn't cover the accessory area. In updateConstraints I set up my constraints:

问题 I'm working on expandable table cell, and my algorithm is follow: I create two views. Create the height constraint of second view, drag it as IBOutlet to my cell. When cell is selected change status of selected cell. class ExpandableCell: UITableViewCell { @IBOutlet weak var expandableCellHeightConstraint: NSLayoutConstraint! @IBOutlet weak var expandableView: UIView! var isExpanded:Bool = false { didSet { if !isExpanded { self.expandableCellHeightConstraint.constant = 0.0 } else { self

Autoresizing，Autolayout

Autoresizing，Autolayout，size class之间的关系 1.Autoresizing和Autolayout两者之间不兼容，若想使用Autoresizing就不能使用Autolayout 2.若想使用size class就必须支持Autolayout Autoresizing在代码中的使用 子控件相对于父控件的变化 UIView * redView = [ [ UIView alloc ] init ] ; redView . backgroundColor = [ UIColor redColor ] ; CGFloat x = self . view . frame . size . width - 100 ; CGFloat y = self . view . frame . size . height - 100 ; redView . frame = CGRectMake ( x , y , 100 , 100 ) ; /* UIViewAutoresizingFlexibleLeftMargin 距离父控件的左边是可以伸缩的 UIViewAutoresizingFlexibleBottomMargin UIViewAutoresizingFlexibleRightMargin UIViewAutoResizingFlexibleTopMargin

问题 I am having a view on which I am setting an ImageView. Auto layout is checked. It looks good in the preview, but when app actually runs on the simulator, there is blank space is showing at the top as well as bottom only in the iPHone retina 4 inch simulator. on 3.5 inch it looks fine. Using iOS7 and XCODE 5. Even though i removed image from view, still there is the same problem. What can be reason for this blank space ? 回答1: I think are you Forget to adding splash screen Default-568h@2x.png
