问题 I'm running into a problem with the autolayout for my detail view in a UISplitViewController . My view hierarchy contains a UIImageView with a decorative element, and the image view's intrinsic size seems to be screwing up the layout of the rest of the controls. These are the constraints I have specified for the image view: H:[UIImageView:0xc83ba90]-(NSSpace(20))-| H:|-(NSSpace(20))-[UIImageView:0xc83ba90] UIImageView:0xc83ba90.bottom == UITextField:0xc83d2d0.bottom V:[UIImageView:0xc83ba90

Wrap items in a horizontal UIStackView on multiple lines

问题 I am working on an iOS app which display a UITableView of items. Each row will show a list of tags with different widths(given by the tag's text length). I can place all the tags in a horizontal UIStackView but I want them to wrap on multiple lines instead of o a single scrollable one. Basically I'm interested in a functionality similar to FlexBox's flex-wrap property. I've attached an image for reference. Any ideas how to achieve this? 回答1: There are a number of different ways to approach

UILabel word wrap feature leaving space even when sufficient space available for the word

由 元气小坏坏 提交于 2020-05-24 05:07:16
问题 The problem coming even in storyboard. The UILabel is having following properties: numberOfLines = 0 lineBreakMode = .byWordWrapping Constraints: Leading & Trailing 26 points to superview; vertically center. Custom Font: Medium 17 Points. As you can see the fourth word cannot fit in the first line and hence a problem by creating bad layout. If I remove the last word the sentence fits in one line completely or say the fourth word. If adding a word after it moves both of them to next line which

问题 I am facing issue with contentView height constraints. All labels have dynamic height i.e no fixed height. I have read somewhere to set height equal to scrollview height. The height of ViewController is currently 870px, scrollview height is 757px. I have no idea how can i set height in AutoLayout , as I am unable to scroll after a certain point.

由 不羁的心 提交于 2020-04-11 05:09:11
问题 I need to autolayout a storyboard UIView with a single UIControl.

I added 4 constraints Center Y Alignment - View - Superview Center X Alignment - View - Superview Equal Widths - View - Superview with multiplier set to 0.9 Aspect Ratio - View - View with multiplier set to 1:1 This setup works fine in portrait

Searchbar behind Navigationbar

问题 Given 3 Controllers: A,B,C A has a hidden navigationbar. Calls Controller B via a StoryboardReference. Controller B shows Navigationbar on viewDidLoad. It has a searchbar and a collectionView. See screenshot A of my storyboard. Calls controller C if a cell is clicked. Problem: If A calls B the searchbar is behind the navigationbar (Screenshot B). It appears with the transition from C to B (Screenshot C). Navigationbar is already translucent. Any ideas? EDIT I realized that my animated
