Detecting text hilight in a UIWebView - objective-c

I am using a UIWebView to display text on iPad. So far so good. Is there a way to detect when the user hilights text on a page, and override the default menu action so I can have the text do other things?

Xcode IB: Replace button with another type?

In my Xcode project, I have a few buttons in the main window that I would like to replace with another type of button. In this case, there are a few rectangles and a rounded rectangle button. Is there an easy way to replace the buttons with another style, or am I stuck with deleting them and settings them all up again? Thanks in advance!
You can select button type custom and use your own special background as the button in Interface Builder.
If you want to further customize your button, I suggest making an outlet of it and customize it programmatically.
Good Luck!

Imitating keyboard delete key with a button

I am using a UIWebView for text and emoticon/smiley display in my app. I can input and delete the text and emoticons using the keyboard, but I want to have a button in the UI which will do the same thing. How can I imitate the keyboard delete functionality with my own button?
My guess would be that you have to set up some sort of communication between the native app and the webview so that you can pass certain events to be handled accordingly. Check out the post here NSString in UIWebview that might shed some light on how you can solve your problem.

How to make a tab bar that shows colored icons , on iOS?

I need to make a toolbar on the bottom of the screen with some buttons. I want in every button to have a small image and a small text under it. The closest i can find from "Xcode" is the "Tab Bar" where you can put icons and text but the problem is that when you add an image you can only see the shadow of the image and not its colors.. Can i change that? Or is another way to make a toolbar like the one i am describing?
EDIT
I need the buttons to change controllers and i just noticed that i cant create actions for the tabs but only outlets. So i guess the tab bar is not what i should use. Any ideas for a toolbar?
Yes Tab Bar is the Best approach for it and it is very easy to customize the tab bar if u are using IO5
This LINK will be helpful.
There is another approach (which was applicable uptil IOS4 for customization of Tab bar) was to Create Custom buttons with tab bar look alike Images. it will give u the same feel, but like i said it is very easy now to customize IOS Tab bars
Here is a couple of Links for u
LINK 1 With Story BOARD
LINK 2 Without Storyboard
One More thing Try searching Google before Posting a question here if have some problem then feel free to post along with the code or tutorial u tried.
Let me know if i Worked

Can I add a hyperlink inside a tooltip in an NSView?

I want hyperlinks in the tooltips of my OSX application, which then link to the Help Book in various places. Is this possible?
No, a tooltip is always placed next to the mouse with no possibility to click on it. But I guess you could achieve the look of a hyperlink by using NSAttributedString, although I'm not sure if the tooltips render them correctly.

adding an invisible button to the background in IB

I'm working with Xcode doing a Ipad app.
i simply want user to click anywhere on screen (not counting text fields) to perform some IBAction.I'm using an invisible button that covers my whole view.
Since I have some text fields in my view,i need to add this invisible button to the background of my user interface. I cant seem to find this option in the button attributes? any help?
Just set the button's type to custom.
Did you try setting the opacity of the button to zero?
I guess i got your point. You just want to put the UIButton(invisible) on the back of all the UITextField. The simple solution to this is open the Document Window in the IB. Now expand the view tree in the list view. Just drag your UIButton above the UITextFields and set the alpha value for the button in the property to be zero.
Hope this helps!!
iPad users don't "click". They "tap" or "touch".
In Interface Builder, I believe views are constructed with a z-index from top to bottom as they appear in the document window, so dragging your button so that it appears as the first subview of your main view should be a quick fix for this.
Have you considered other approaches? This doesn't sound like standard behaviour for an app and will probably cause havoc with anybody using Voice Over. What are you trying to accomplish?
