I'd like to make a text based app with clickable text in a scrollable screen. Can't seem to do it with TextView.
Let me explain: you open the app and there is a long paragraph. You scroll down and click on the word hammer (which is probably colored or bolded) and a small pop up window appears with a definition of hammer. How is this possible?
If you'd like to see an example, here is a youtube vid of somewhat similar functions in a bible app (though they don't use a pop up box): http://www.youtube.com/watch?v=qNCgePlBamQ
Any help would be appreciated
You could use a UIWebView and HTML
and this: iOS Clickable Words (UILabel or UIbutton's) was asked suspiciously recently

I need to display a text message on screen.
Currently I am doing this with a Text view on a transparent window, so the text is overlayed on the screen, perfectly.
The issue is that if am working on a text editor, or Excel, the popup shows up it blocks the text editor by an invisible rectangle around the text, i am unable to send mouse clicks or text keys to the window that i was working on.
I know there are ways to do it, some applications already do it, I just need to know how.
Take a look at this question. It is in Objective-C but the API details you need are there, you just need to do the equivalent in Swift. Whereas that answer draws a transparent red border you will draw your text transparent.
I need to highlight text in epub book,when user selects the text,i can get the text,what the user has selected,but i need to highlight,the text permanently what user selected,thanks,any help will ne appreciated.
There's nothing built in to iOS that will do this. Some broad techniques that might work:
If you're showing the book in a web view, you might be able to wrap that area in a span and style it to create a highlight.
If you're using Core Text, you could draw the highlight in directly, either before or after drawing the text. (Your choice will decide how the highlight affects non-black text.)
You could add a transparent view over the text that draws in the highlight.
As for adding highlight-related items to the selection menu, see this Stack Overflow post. You probably won't be able to get icons in the menu like Apple does, though; that seems to be a private API. You could probably override the whole menu system if you want something closer to Apple's look, but that'll be quite a bit of work.
We are trying to write a training manual application for the iPhone. On the top half of the screen is a diagram of a car engine, on the bottom half is some text. At the user repeatedly hits a "next" button, we highlight different parts of the engine, and in concert we highlight different parts of the descriptive text below.
We basically want "living text" in the text half, with the illustration following along on top to where the reader is in the text. What we'd like from the text is 1. user can scroll it using their thumb so possibly a UIScrollView 2. the software can explicitly drive a scroll to any part of the text (when they hit the "next" button). 3. the words in the text are interspersed with hotlinks e.g. "this is the camshaft... this is the piston..." and the user should be able to click on any of the keywords like camshaft, piston, and have the diagram highlight that. (The problem is not highlighting the diagram, its capturing the click). The text would have 300~400 buttons/links/keywords and about 600 words of text.
Since this is fairly similar to using a web browser, we tried using Apple's version of webkit using a UIWebView and handleOpenURL to register a service back to the app itself. But Webkit for internal links a popup comes up asking permission to access that link. Every single the user wants to go to a link (in our case just an internal event that we'd intercept so that we can highlight e.g. the camshaft). Tried to intercept the event from the HTML view, but that didn't work.
It seems like the best we can do is to abandon scrolling text, and make the text part more like flash cards or a power point presentation, breaking the text into custom UIViewCells with buttons inside a UIScrollView. However, this would impose an annoying constraint on the author that they would have to write everything to fit in the UIViewCells, sort of chunky.
Any ideas would be appreciated.
This is definitely something you can use a UIWebView for. Don't use handleOpenURL, rather, set your viewController as the webview's delegate, and override -webView:shouldStartLoadWithRequest:navigationType:. When this gets called, check the request, and pull out your link data from there.
It would probably be easier to implement that completely in JavaScript in the document you load in a UIWebView. You would have to use JavaScript (i.e. [UIWebView stringbyevaluatingjavascriptfromstring:]) anyway to achieve things like scrolling to a certain position.
in my app i use a navigation controller and a tabBar for my views. The problem is that the titles that i have for the views are a little too long to fit.. they appear like in the photo below.

could someone give any suggestions for resolving this problem? i tried subclassing UITabBarItem but i can't add a label as a subview, i can't change the font or size.. it looks ok when i have only 4 buttons but that is not ok because i need that more button. cutting down the names is not an option either, i don't think apple would like that.
thank you in advance.
As far as I can tell, there is no way to do what you want to do easily.
You could build some of the name string into your icon image. This will of course force you to internationalize your icon images, and you will also end up with the blue coloring in some of your text.
You could have no titles at all, and overlay your font-scaled title by drawing on the containing view. Note that when there is no title in the tab bar item, the following page will also have no title in the title bar.
Better by far, if you can do it, is to shorten the names. I know this is tough in German, but surely there must be alternatives.
I hope that Apple improves this in 4.0, but as those fonts are already fairly small, I sort of doubt it.
Regarding the SMS compose view as show in the picture below:

I have two questions:
1) How is the text entry box implemented? There are no standard control from the API and the box is smart enough to resize when you press enter OR when the text is too long. Also the bar resizes with it. How is this done with the least coding?
2) How to code it such that when the keyboard shows up the whole view shifts up? Typically when the keyboard shows, it goes over your current view.
