iphone - How does one interact with a string drawn using UIStringDrawing/CoreText -


I'm trying to work on an app that highlights some key words. For this reason, I'm seeing the use of CoreText or UIStringDrawing to highlight these lessons (such as bold / underline / italicize / color) in UITextView are not these features (and I have no luck with CatPlayer ).

In any case, I am capable of manipulating and pulling the string successfully. (Ii- I can find my key words in a string and apply appropriate symptoms).

The problem I am facing is that when the text is ready in such a way, it can not be interacted directly. Since the user may be able to delete / text the text view in question, this is an important thing.

At the moment, I have been trapped in the Drawing Routine. UITextView subclass (mostly just to see what I want to do). Is there a different method in the UITextView, which can be overridden, so that it uses my code to present my string? If not, how can I go about what I describe?

See the example of what I'm talking about, how the notes app searches and highlighted the phone number and address I am not looking for a phone number or address, but this point Comes.

Extra reading after a while, it seems that to create your own text view There are a lot of ways to sub-class / override whose text you can draw, the apple docks touch it, but they do not go into more detail.

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
