Dynamically sizing text with kerning to occupy the full width of a UILabel

由 馋奶兔 提交于 2020-01-29 19:46:11
问题 I have a layout with a UILabel placed above a fixed width view, shown below as a grey rectangle. The text needs to match the width of the fixed grey view. I achieved this by setting the adjustsFontSizeToFitWidth property on the UILabel to YES , settings the font size to something really large, and setting the minimumScaleFactor to something suitable small. This worked fine until… I had to add kerning to said text. I added the kerning by applying @{NSKernAttributeName: @1.40} to an attributed

How do I reuse a view inside UIPickerView in this case?

由 感情迁移 提交于 2020-01-25 10:14:38
问题 It seems that a lot of people just return a UILabel, but in my case I'm adding a label to a view. The view is never not nil. This is a different use of UIPickerView, because I'm rotating its components 90 degrees and having it scroll sideways instead of up and down. func pickerView(_ pickerView: UIPickerView, viewForRow row: Int, forComponent component: Int, reusing view: UIView?) -> UIView { if view == nil { let customWidth = 300 let customHeight = 300 let view = UIView(frame: CGRect(x:0, y

Is it now possible to have Multiline UILabel with adjustsFontSizeToFitWidth?

由 只谈情不闲聊 提交于 2020-01-25 08:53:10
问题 I struggled in the past to have UILabel adjustsFontSizeToFitWidth working on multiline labels. I soon have found also here on stackoverflow that adjustsFontSizeToFitWidth property "is effective only when the numberOfLines property is set to 1". I remember that this was written in the official documentation. But now I can't find it anymore I was testing my code on Xcode11 with the accessibility inspector to find out labels that needed to be embedded in scroll views. I found out a label that

Autoresize multiline UILabel in Swift

由 会有一股神秘感。 提交于 2020-01-24 22:08:44
问题 I have tried everything to auto-resize my UILabel in Swift. I can autoresize the text when it is one line but when it is two lines it no longer works. The text in the UILabel changes often happening about every 10 seconds. The code I have tried is: let direction = UILabel(frame: CGRect(x: 95, y: 10, width: screenWidth - 95, height:100)) direction.numberOfLines = 0 direction.adjustsFontSizeToFitWidth = true direction.lineBreakMode = .byWordWrapping direction.textAlignment = .center direction

How can I underline part of the text like iPhone SMS?

由 醉酒当歌 提交于 2020-01-24 10:13:23
问题 I use an UILabel to show my text, in a multi-line and UILineBreakModeWordWrap mode, and the maximum width is 200. For example, here is the text: I really really want to underline first word and second word, could you help me? And I want to underline "first word" and "second word". If the text is shown in a single-line mode, with sizeWithFont method of NSString, I can easily calculate the position of "first word" and then override - (void)drawTextInRect:(CGRect)rect to draw the line. But in

How to add padding to an UILabel? [duplicate]

由 我怕爱的太早我们不能终老 提交于 2020-01-24 02:40:47
问题 This question already has answers here : UILabel text margin [duplicate] (38 answers) Closed 6 years ago . The text inside an UILabel is smashed against the left and right borders. Is there an way of adding some inner padding to the UILabel, so that text won't touch the inner borders so closely? 回答1: Just adjust the position of the label (I'm not aware of any other method, although someone else might). If you have an issue with background colors (for instance), make the background a separate
