I am designing an interface that basically looks the same as the Settings application. That is, I have a grouped TableView with cells that look like UITableViewCellStyleValue1. There are labels with values associated with them. The difference is, I am making custom UITableViewCell nibs so that the "value" can be a textbox, segmented cont...

I want to allow a pushed to set parentViewController's instance variables. For instance, VC1 (the parent) has a bunch of textfields and what not which are filled from VC2 (the child). VC2 is pushed onto the stack by VC1. I've tried doing like parentViewController.myString = "foo"; however since parentViewController is a UIViewController,...
How much memory will consume a texture loaded with this method ? With this method, will a 1024x1024 texture consume 4MB anyway ? ( regardless of loading it as RGBA4444 ) ? -(void)loadTexture:(NSString*)nombre { CGImageRef textureImage =[UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:nombre ofType:nil]].CGIm...
What's the simplest way to have a scroll view (with pagingEnabled set to YES) have a page width set to something other than the scroll view's bounds? Let me give an example. Suppose I have a scroll view with 10 items, each 150 pixels wide, and my scroll view is 300 pixels wide. If I start with views 1 and 2 visible and scroll horizontal...

I have an image that is set to content and is in the root of the bundle. I have verified it is there in the simulator. When I construct HTML to display in the UIWebView, this HTML fails to show the image: Is there a relative path it should be in? Note: I use the bundle as the base path in the call to show the html. (I use MonoTouch...

From an MKCoordinateRegion, how do I tell what the top of a mapview's visible area is? The MKCoordinateRegion will have a center point (coordinates). Do I then add the latitudeDelta to the center point latitude to find the top of the map? Or must the delta be split in half and each half added and subtracted against the center point la...
Hello, this is my first question, so if I didn't do the tags correctly, I'm sorry. I tried... Well here is my question: I am hoping someone can tell me how to do a 2-line section header for a plain tableview. The problems I am having are: 1) I cannot find an image that will mimic that of the default 1-line section header. Can someone sha...
I'm trying to position a div in the center of the iphone viewport. Basically so that when you hit an image, it pops up in the middle of the screen regardless of where you had scrolled to on the page before you clicked. It's not as simple as just making it position: fixed; as that will cause the origin to be the top of the page, not the ...

I downloaded an app with nice design and unpacked it's contents. I'd like to look at the NIBs to see how the app is put together. I renamed the NIBs to XIB, but Interface Builder won't open them ("Interface Builder was unable to determine the type of PageView.xib"). Is there any way to force it to open the file. Would I be able to see an...
