I would like to achieve a selected text like in the picture below.
But all existing answers use selectAll(nil) which displays this instead. See the little edit draggers ? I don't want them. Is that possible ?
I`m starting in Objective-c this Year and I found nothing that could help me in the logic of how elaborate it:
Look!
I have a UITableView with a list of drugs. When I click on any medication, I'm taken to a DetailViewController that displays the text information about this drug. In this text, I want every time a drug name appear, it appears as if it were a “link”. So when the user clicks, it will be taken to other remedy detailviewcontroller without need to go back to the list of remedies! What is the better way to implement this?
I thought about passing an array with all drugs for DetailTableView controller via Segue, and then conduct a search for any of the remedies present in the text, but i don't know how to turn that word into a link, or set a function to become part of the text (the drug name) clickable
Just to make it clear, let's assume that we are reading the details of the text on the drug called Amoxicillin:
“Amoxicillin drug works better than erythromycin”
What I want is that the name Erythromycin become some kind of link, so when the user clicks on it, is brought to the screen details about erythromycin. Do you guys understand what i mean?
P.S.: I saw that the UITextView has an option called "Links" in attribute inspector, but i have no idea how to use it or if this is for what i want
Thank you all again!!
Use UITextView And select these attribute.
Is it possible to add a text link into a TextView? I want the link to perhaps behave like a button, where I can assign an action to it.
EDIT: When I say assign an action, I mean actually giving it something in the code. I'm wondering if it's possible to dynamically add a "button" into text that I can assign a coded action to.
Live scenario
Think of something like a dictionary app. Maybe the definition of one word uses another word that you might not know the definition of, so being able to click on that word to instantly search it rather than having to type it in would be a nice user friendly feature. It seems rather unlikely, though, I guess.
I would recommend using NIAttributedLabel from Nimbus, an open source iOS library. You can specify text ranges that are links, and you get delegate messages sent when a user taps on it.
Main Nimbus site: http://nimbuskit.info/
NIAttributedLabel docs: http://docs.nimbuskit.info/interface_n_i_attributed_label.html
in the inspector, go to the Text View Attributes tab then make sure "Detect Links" is checked.
Yes you can. Add the URL into the text view, then open up the Attributes Inspector. You will see an option in there to detect links.
I know of a way, but its a LOT of work. First, you have an NSAttributedString that you have the text view display. Second, attribute the range of text you want to be the button. Third, assign a tap gesture recognizer to the text view and in the method called by the recognizer, you'll use core text to determine if the tap happened over the range of text that represents the buttons.
Heres how youll use core text: create a framesetter with the attributed string. Create a frame from the framsetter with the shape of a square that is the frame of the text view, inset by the padding of the text view. The frame will allow you to get the y origins of every line in the text view and and once you know what line the tap happened on, you can use the line to then figure out exactly what character was tapped on that line by giving it an x offset. Once you know character index on the line, you can add it to the beginning of the range of the line and get the index of the character within the whole string. Then you can check if its within the range of the text that is your button. If it is, you can then call a method to simulate a target action type behavior.
Ive explained the process of how to accomplish this and specified what kinds of core text objects youll need, ill let you look up the specific api details:

You can also use my objc core text wrapper:

What about CoreText? It Can draw many kinds of Text .
I have a text area that has names within the default value. For example the textarea reads..
(dynamic registrant name) just registered to become
a donor in (dynamic from pull-down above)
honor. This text is editable
So in the same form I have an input that asks the user for their name and a select box where they can choose among a selections of names. I am trying to change the names within the text area based on the values they enter in the input and drop-down fields above the text area. Can someone help with this? I am completely stuck. I have read through some of the forums here and it looks like a lot of the solutions are to use ajax. I have zero experience in ajax and would like to find a solution that does not use that...is it possible? Or could someone help with a solution?
I don't think textarea is what you want exactly. What if the user takes off the (dynamic from pull-down above) part? How would you know where to put the text at? Even if you somehow could, I suggest you make regular text input elements for contents that the user can change and put the other dynamically changing text as uneditable html text elements (or however you want to format them).
I have some textfield with text like "Click #button1, then #button2". Have you got any idea how to replace keywords by images ? I must do it in AS2 :/ I know there is htmlText in textField, but useing it I can only use one image, and image can only align left or right site.
Very advanced stuff. I can tell you there is no 'out of the box' solution like using html text fields or something similar. Especially if you want to mimic nearly html behaviour you have to code advanced routines that can : 1. recognize your keywords. You should google for tokenizers and 2. layout textfields according to occuring images and textblocks. Again, thats advanced!
