  • iPhone - nested views & controllers

    - by codemonkey
    Is it possible to have a single iPhone screen with its view loaded from a xib by that screen's UIViewController, but then another UIView within that screen with content loaded from a separate xib file? If so, is it possible to have that nested view's events handled by a separate custom UIViewController subclass from the rest of the screen? If both of these things are possible, are they also advisable?

  • iPhone - Track three touches

    - by Striker
    Suppose you have three points of contact on the iPhone screen and one of those touches moves... The touchesMoved method will be invoked and the [[event touchesForView:self] count] will be equal to '3' because there are three touches for the event, but how can you distinguish between the touches? For example - find out whether it was the first, second, or third touch which moved? Thanks.

  • Syntax highlighting on iPhone Text-Editor

    - by pbcoder
    Hi, I want to write a simple text editor for iPhone with syntax highlighting support for c,c++. But the problem is, I dont't know how to do this. The first solution I was thinking about, was to go over the text and highlight keywords when the value of the UITextView has changed, but I think that if I got more than 1000lines of code that doesn't work very well. Thanks for help!

  • Adding procedural C openGL functions to an iPhone project

    - by user309595
    I want to add a few drawing functions to an iPhone project for drawing things. Something like drawTile(x,y,len,wid); which would call openGL to draw a box somewhere. I should just be able to write a procedural C file to do this but the openGL libraries are objective C and I'm getting weird errors. Do I have to make a class for all of my drawing commands and call class methods?

  • typical memory usage of an iphone app

    - by climbon
    According to Instruments 'Net Bytes' of my app are never more than 2MB yet sometimes I receive memory warning and the app crashes because some views on the stack are unloaded by force. I'd like to know what is the typical memory footprint where system would not send you memory warning and unload the views ? I have so far tried this on OS 3.1.2 on iphone 3GS and 3G and with 3G giving warning almost 80% of the time I test the app on it.

  • Structuring iPhone/iPad application views

    - by Mark
    I have an idea about an application that I want to build and Im new to iPhone/iPad development (but not new to development in other languages/frameworks such as .NET and Java). I want to layout some views on the screen so that they animate (slide in) from different directions into their places. The question is about the strucuture of the application, if I have say 4 rectanglular areas on the screen that contain business data, such as contacts (name, photo, etc...) and they all take up different widths of the screen (say the first contact takes up one row of the screen, but the next 2 take up half the width of the next row each, and so on). Should I create a custom view for the different sized contact views, (i.e. LargeCustomView and SmallCustomView, and any other special type that I make) or should it all be one type, say, CustomerDetailsView which could be stretched to fit at design time? Also, if there were, say, 3 different instances of the same custom view on the one screen, are there 3 instances of the view controller also? Im a little confused about powering the data behind a view, can someone shed some light on this for me? Do I just set the properties (say an instance variable ContactForView) on the view controller for each instance? Thanks for any help you can give Cheers, Mark
