CGRect for selected UITextRange adjustment for multiline text?

由 和自甴很熟 提交于 2019-12-31 20:49:05
问题 I've used this answer in order to create a CGRect for a certain range of text. In this UITextView I've set it's attributedText (so I've got a bunch of styled text with varying glyph sizes). This works great for the first line of text that's left aligned, but it has some really strange results when working with NSTextAlignmentJustified or NSTextAlignmentCenter . It also doesn't calculate properly when the lines wrap around or (sometimes) if there are \n line breaks. I get stuff like this (this

How to resize UITextView while typing inside it?

问题 I'm creating a comment section much like the one Facebook uses for it's messaging section in it's iOS app. I want the UITextView to resize the height so the text I'm typing fits inside it rather than you having to scroll to see the text that overflows. Any ideas how I might go about doing this? I've looked into maybe using a CGRect that is assigned to the size and height of the text view which then matches the content size: CGRect textFrame = textView.frame; textFrame.size.height = textView

UITextView member variable is always nil in my UIViewController

由 冷暖自知 提交于 2019-12-31 05:42:12
问题 In my nib, I have a UITextView component. In my UIViewController I have a UITextView member field and I have used IB to make sure that the two are connected (at least I think I did that by dragging from "Files Owner" and dropping it on the UITextView in IB and selecting my member variable). Now, when I update the text via setText: , the UITextView still remains blank. When I break into my code, the member variable (called textView ) is nil . So I am guessing I have not used IB correctly. How

Get text range of link in UITextView

由 为君一笑 提交于 2019-12-31 03:26:48
问题 I have a UITextView that contains a link and some other text. The link detection is enabled and working (iOS8). However, I am at loss to find the range of the link within the textView. The idea is that the text is scanned (after link detection is done) and the link preloaded into a web view, so that when a user taps on an element somewhere, the web view can reveal itself. How can I get the range of the detected link within a UITextView? 回答1: A way to do it, is to use enumerateAttribute

The error I get is like this one: Error Domain=NSCocoaErrorDomain Code=2048 "The value “*” is invalid." UserInfo={NSInvalidValue=*} Is there a way to avoid this problem and have the code handle all the text like plain text? Because I

iOS — UITextView disable scrolling but enable touches

由 断了今生、忘了曾经 提交于 2019-12-30 08:01:50
问题 Is there any way to do this? What I really want is a UITextField where I can control the location of the cursor. But as far as I can tell, that is impossible. So I am looking at using a UITextView. This does allow one to control the cursor location. But scrolling is getting in the way -- my text is scrolling here and there, and I don't want that. 回答1: UITextView is a subclass of UIScrollView, so you can prevent the view from scrolling by setting the property scrollEnabled to NO . 回答2: If I
