how to display text of textview one by one with animation, but I don't know how to do that.
For animate the textview is ok, but no luck for text.
I need help, and thank for answering !

I need a view that allows me to have an editable method of text entry that is limited to one line, but can scroll horizontally. After a bit of research, I found that maybe a UITextView would work well.
This is going in a table view cell so I've tried putting this in awakeFromNib()
code.textContainer.maximumNumberOfLines = 1
code.layoutManager.textContainerChangedGeometry(code.textContainer)
but this is what happens (I'm repeating the same line to fill the text view)
So for attributes I need to assign, I need:
Disable Vertical scrolling
Enable Horizontal scrolling
Limit Text View to one line
If anyone also knows a better way to do this (maybe with a scrollable Text Field?) I would love to hear it.
Thanks in advance!
I am trying to create a textview that holds a 3 line string. As the user works, the string will update and become wider, the height (number of lines) will remain the same. Reading through the documentation I understand that the size of the container cannot change, it is readonly.
I have code that places text into the text property of a UITextView but it will not scroll the text right or left. I played around with inserting a UIView into the textview and believe that will work, but doesn’t seem like the way to about this. I’m kind of figuring that I need a custom UITextView class and a custom NSTextContainer. Wondering if the proper direction? Any help is appreciated.
Thanks,

I have a narrow UITextView (about 1 line in height) to which I only add text programmatically, setting the text property of it as I click buttons. I also handle the cursor position manually, setting the selectedRange as the text changes. All works great as long as I have only one line of text.
When I have two or more lines of text and try to insert text at the first line, the text is inserted correctly and the cursor position is still at the right place but the UITextView scrolls to the bottom. When I then add another piece of text at the top it scrolls up to the "correct" position. This pattern then repeats for every entered piece of text at a line other than the last, making the UITextView scroll up and down for every button pressed.
I also tried calling UITextView scrollRangeToVisible: passing the selectedRange property as argument after setting the new text. That didn't work either.
I finally tried setting selectedRange after a 0.5 s delay after I set the text. Then it works as it should, but only after the UITextView has first been scrolled down to the bottom for 0.5 s. This seems to indicate that the setText method of UITextView is asynchronous in some way, and completes after I have already set selectedRange or called scrollRangeToVisible, and readjusts the UITextView to what it believes is the desired.
Can anyone tell me what is going on, and how I can get around the problem.
Thanks!
The auto scroll behavior of UITextFields can be annoying and difficult to harness at times.
Do you need the user to manually edit the text? If not, use a multiline UILabel.
If yes, also use a multiline UILabel and exchange it on the fly against a UITextView once the user taps. Change it back on didEndEditing. This techniques has worked well for me in table views.
I solved the problem!
When starting in the maze of creating a custom input view, I began implementing UITextInput and I found that the UITextInput protocol declares many interesting methods. And what is awesome is that UITextView implements that protocol. So even though it's not in the immediate UITextView API reference, you can call all UITextInput methods on your UITextView. For instance insertText: (from UIKeyInput protocol) and replaceRange:withText:. They made it much more flexible to programmatically work with a UITextView. Hope this can help someone else too!
I've looked around for an answer here but didn't come along one that really helped me. directing me to a proper answer I may have missed is greatly appreciated too.
I have a label defined in the simplest manner :
IBOutlet UILabel *eventIDLabel;
IBOutlet UILabel *eventTitleLabel;
IBOutlet UILabel *eventDescriptionLabel;
now the description label can vary in content. May have 1 line or multiple lines. I want the label to resize automatically. Now I also want that if more lines than current screen can show, user is enable to scroll down and see the whole content of label.
Very trivial question probably but I am really new and hoping you guys could help.
thanks :D
You could use a UITextView. UITextView automatically can be scrolled, when the entered text ist to long.
You can use [myLabel sizeToFit]
You can also read more about it here
Also if you know it's going to be relatively long, you can consider using TextView which will provide the text scrolling
Hope I helped
How can I add a button in textview? for example..
textView.text=#"text here\n\n text also here\n\n text here aswell";
How can I add a button after each "\n\n" or along the text?
You can create a object of UIButton and add it as subview to yout textview.
You need to preset the frame of the button So the text must be statis and you must know the position of the button in advance.
so your \n\n creates a paragraphs
You can do it without static text just split your text in separate textviews by \n\n, add them to your scrollview. You have to measure your text paragraphs height to set the right frame for textviews and leave gaps for buttons. I would rather use tableview so you dont have to worry about that. Add buttons in between, it is doable.
you may reconsider adding buttons along the text this way (you can but it is really convoluted way of doing things), use webview for that as already stated here by others
