I'm using UIActivityViewController to share a screenshot in my app. From my understanding, we can have a text field, an image, and a URL. What I would like to do is have one of the words in my text field be a clickable URL in itself. Something like,
"Check out my high score in myGameName!" where myGameName is a link to my game's website. Basically what I am going for is just like an html link
Link text
where just the 'Link Text' is actually shown. Is there a way of doing this?
No, the text field/image/URL are all separate items, because some services don't support them "natively".
check this library to make attributed label https://github.com/mattt/TTTAttributedLabel
I think you can have a look at OHAttributedLabel

I'm using DTCoreText DTAttributedTextView in my app to highlight the urls in my text. My other criteria is to be able to select by tapping and holding similar to UITextView. However, DTAttributedTextView doesn't seem to to use a UITextView as a placeholder. Anybody has an idea how I can achieve this?
Thanks
That's a feature that's only available via the paid version of DTCoreText.
from the github page
This is useful for drawing simple rich text like any HTML document without having to use a UIWebView. For text selection and highlighting (as you might need for an Editor or Reader) there is the commercial DTRichTextEditor component which can be purchased in the Cocoanetics Parts Store.
I am trying to accomplish the following:
Read and Parse the text in a UITextField. Identify all the numbers in the UITextField and convert these into hyperlinks.
When these hyperlinks are clicked perform a custom action, which is to display a UIActionSheet and based on the selection assign the number (in the hyperlink) to another UITextField instance
For example if the UITextField has the text - "This is a sample test with number 123445 and more numbers 44555, 66777".
I should be able to parse the above text, detect all three numbers and add hyperlinks to them.
For the first part (parsing) I found out that there is a NSRegularExpression class that can be used to detect patterns in a text. But I could not find a way of adding hyperlinks to the matched numbers. I tried looking at Three20 documentation and could not figure out a way. Even tried the answer in this link - Just how to you use TTStyledTextLabel? but it only auto detects URLs and adds hyperlinks to them, I want to add hyperlinks to any custom text.
Can someone please help me with this. Please do not ask me to use WebView. I would really appreciate some code snippets. Thanks in advance. I am using xCode4.
If you don't need the text to be user-editable directly, you may use my OHAttributedLabel class to achieve this. (here on github)
This allows you to display any NSAttributedString and can also autodetect links, phone numbers and everything Apple's NSDataDetector class is able to detect. You can also add custom links to your label on any part of the text.
See the sample project included in my github repository for more details.
It is very customizable, both for link colors, underline style, action to perform when a link is tapped, which link types it should autodetect, and you can add any custom links and style you need on the text.
I need a functionality like in the iphone pdf reader.
i want that user select some text content and that content should be highlighted with yellow color.
Currently i am using text view and want to know that can i achieve same functionality in it.
or i have to shift to pdf ?
Please tell that how to achieve that in either of the two.
You can try NSAttributedString-Additions-for-HTML
Take a look at EGOTextView
A drop-in replacement for UITextView that amongst other things supports attributed strings. This would allow you to achieve your aim of selecting text, and then applying a style to that selection such as a yellow highlight.
hi
I want to display drop down menu like the one you see in this image http://callingcard.marigoholdings.com/Screenshots.html#1
(below From and To)
How can i create that? Any good tutorial.
Best regards
You will have to use UIPicker for this purpose.This is used as a dropdown whereever needed in iPhone.
Please refer the link below
How to create drop down list box for an iphone app
Thanks
It looks like that app is using a combination of a UIWebView and an html select tag. To do something similar would involve a solid bit of html and javascript hackery, but in essence would be:
Create a UIWebView and inject the appropriate HTML into it to make the dropdown.
User uses dropdown as if it was in mobile safari and picks something.
When you need it, you use a javascript call with stringByEvaluatingJavaScriptFromString: to grab the value of the dropdown by id and pass it back to your code.
There are a few gotchas here, mainly with constructing the dropdown and the webview such that it's big enough to show the expanded dropdown but transparent to see under it when the dropdown is not expanded, it's not scrollable, and that sort of thing.
I wonder if a UIActionsheet might be better ... you could easy make a button to call the sheet. Adding multiple buttons to the sheet transforms it into a table that you can scroll.
I'm working through the Stanford iPhone programming course online. The Presence app assignment pulls Twitter and displays each one in a separate UITableViewCell.
Updates often include URL's and I'd like to know how to display just the URL text in blue, having it be tappable. I can parse the text for URL's with no problem, just no idea how to display the URL itself.
Any advice or suggestions would be greatly appreciated.
As said above a button would work, but in terms of the UI it would probably look more natural if you had a label.
Alternatively, you could fill the UITableViewCell with a UIWebView. The UIWebView would hold all the text and you should easily be able to set part of the text as a link (color blue) using html.
You'll have to add a UIButton (or something similar) to the cell, with the button title being the URL and the action opening the actual link.
