Hey all, trying to learn objective-c. It was going quite well, until I realized I was missing a link. When building in the spirit of MVC, I understand it as you Model and View should never talk to eachother. I have this problem I'm messing around with now. A model containing a polygon class. Contains an polygon object with attributes...
OK, I have a screen in my iPhone app that looks like the following: When the Add Notes cell is touched, I would like for the keyboard to disappear, THEN I would like it to modally display the Edit Notes Screen (which also has a keyboard, but I would like for it to animate back on screen). Right now it animates everything at once (the ...
I am using a tab bar (UITabBarController) on my app and I wish to have more than 20 different views to choose from. If there are more than 5, "More" menu appears. I can access any of my views from "More" menu but I have problems with customizing my TabBar with "Configure" (Edit) navigation bar. I can see only 20 first view icons and I ...
I've been looking at the way resiznig works in Cocoa Touch and it looks like without writing any code, a UIView cannot be set up to size itself based on the size of it's children. There are plenty of options to resize and re-position child views when their containing view changes size, but nothing that works the other way round as far as...
I have an About View which I push onto a NavigationController. The view has one UILabel which is connected to an IBOutlet. In viewDidLoad I populate the UILabel with the bundle version number (a string). Testing with instruments suggested that the line marked with a comment is leaking memory: - viewDidLoad { [super viewDidLoad]; ...
What is the best way of letting the user edit text with in-line images (or at least text with different background colours) on the iPhone? The UITextView doesn't support this. Edit: I just noticed that the e-mail client on the iPhone can edit text with images. So it's definitely possible. ...

I'm slightly confused in one aspect of Core Data. That is, when do I use the rudimentary alloc/init routine vs created an object with core data and saving it into the current managed object context. I know that's a rather vague question, so let me give you an example. I have an application I'm currently working on that iterates through...
So using this link: http://stackoverflow.com/questions/805872/how-do-i-draw-a-shadow-under-a-uiview And this link: http://iphonedevelopment.blogspot.com/2008/11/creating-transparent-uiviews-rounded.html I came upon this implementation: - (void)drawRect:(CGRect)rect { CGContextRef context = UIGraphicsGetCurrentContext(); CGContextSav...
Exactly as the title says, why does Core Data create instances of NSManagedObject with properties for each entity's attribute, but no accompanying instance variable? The problem is, I would like to use some of my 'Entities' in a typical alloc/init style fashion in some parts of my code. Not using Core Data's fetching/context to create/st...
I am currently using the iPhone SDK to create an app that utilizes Indic scripts. However, the iPhone has issues with rendering certain glyphs in many Indic scripts. For example: प + ् + र = प्र or ਕ + ੍ + ਰ = ਕ੍ਰ When you type this on a Mac (or Windows) the computer will automatically render the three characters into the one gly...

I'm playing with writing my first iphone app; SDK 3.0. I've got a UITextField, and when text gets entered into that, I want to obtain the doubleValue from the text field and perform some computations and display them in a UITableView. The delegate for the UITextField adopts the UITextFieldDelegate protocol, and implements both textFiel...

Starting with Atebits Fast Scrolling in Tweetie post I have a UITableView subclass that does all of it's drawing in the drawRect: method of it's contentView. This works perfectly and is super fast.

Despite looking at similar posts on this site and google, I just can't wrap my head around how to post to a php page from the iPhone. Here is what I want to do: I have a php script, say at www.mypage.com/myscript.php that I could post to normally by doing www.mypage.com/myscript.php?mynumber=99&myname=codezy This in turn will add a lo...

Im assuming Im going to have to use XML but how..? I'd rather try RSS if I can? Or what ever way works! Thank you so much for helping! ...
I have a UIControl subclass for a custom slider type control (one that behaves differently from UISlider). At the moment I use my own target and action variables to send a message to the target whenever the slider value changes. But this doesn't play nice with Apple's UIControlEvent constants. I wasn't sure if I should use these, and if ...
I can't seem to get the text to actually span multiple lines. The heights look correct. What am I missing? - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { UITableViewCell *cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:@"StatusCell"] autorelease]; ...
I would like to encrypt a string with AES 256 on the iPhone but have not found much via google. What I am trying to do is post some data to a web site as part of a game I am creating, but I do not want the user to be able to cheat by seeing how it is posted because it is plain text. So I want to post one encrypted string to my php page...
