I created an "SDMutableGrid" class so that I could use a grid. It's just a child of NSMutableArray that contains a number for arrays equal to the number of rows in the grid. Currently, the program quits before it really starts and it appears that it is because the methods defined for NSMutableArray somehow do not apply to SDMutableGrid...
The short version is that I have a protocol which has an optional parameter. When I build a class that implements it with the iPhone SDK 3.x it compiles just fine, with no errors or warnings. When I used the 2.x SDK I get the following warning: Class.m:68: warning: property 'field' requires method '-field' to be defined - use @synthesiz...
Hi, I am creating a photo preview application - it has some photos in it. When I had not a big amount of images, everything was fine. The app uses UIScrollView to switch between images, basing on the PageControl code example. But now I added more pictures and I have some trouble with it - it consumes too much memory and my app starts g...
Hi, I want to make a 2D tiled background system on the iPhone. Something that takes a tilemap and tileset image(s) and converts it into the full map on the screen. Just doing some messing around, my first approach was to create a polygon for each tile. This worked fine until I started testing it for 400 polygons or so, then it starte...

Hi, I would like to have a UIView with the same background as a UITableView with the UITableViewStyleGrouped style (its that grey-white pattern seen in the Settings App, for example). Is this possible? Thanks in advance MrMage ...
Why doesn't the cell show anything in this code: UIActivityIndicatorView *spinner = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleGray]; [cell.imageView addSubview:spinner]; [spinner startAnimating]; cell.textLabel.text=@"Carregando..."; [spinner release]; I'm doing this inside tableView:c...

I'm learning to develop for iPhone (programmatically, I don't like IB). I only use IB for the frames of things, so I design in IB but only use it to check each control's frame. Something I've gotten very confused about is the frame of a UIView. First of all, if you do not implement loadView in a view controller, it automatically creates ...
I am using Three20 for the iphone and I am trying to change what a method does within it by using a class category. It compiles fine, but I never reach the break point in it. I'm assuming a class category affects all instances of the class, so I don't have to recompile the static library for it to work. I also know that the class I'm u...
I have uiimageviews as subviews for uiscrollview. I made my uiviewcontroller resize the scrollview contentsize and offset similar to how it was done here: http://github.com/andreyvit/ScrollingMadness/tree/master. The only difference is that I don't want my image views to take up the whole screen but try to stretch proportionally so I u...
If I create a UITableViewController - drilling down works as expected. If a user selects a cell and I implement 'didSelectRowAtIndexPath', the cell flashes blue and the next view shows up. But, if I include an 'edit' button (self.navigationItem.rightBarButtonItem = self.editButtonItem), when the user clicks 'Edit' - the mode correctly c...

I tried browsing the Internet but I get confused. Can anyone ...
The UISearchBar in my UITableView header is the strong color. The TableSearch uses the more subtle code, but I'm not sure how it's doing it. I've looked at the TableSearch example code. Specifically, I don't see tintColor being used anywhere in this example. I don't see opacity or alpha used, either. How does the TableSearch example do...
Hi all, Is there a way to get the iPhone's carrier, and/or the current signal strength, using Objective-C? I know how to determine if a data connection is present, and whether or not that connection is wi-fi vs. cellular. I also know that you can manually place the iPhone into "field test" mode by going to the phone app, and dialing #...
Hey guys, I'm a beginner when it comes to iPhone development and i've searched for the answer to this question and haven't found anything yet. What i'm trying to do is allow the user to move an object without actually touching the object (they can touch anywhere on the screen) and as they move the object will go from where it was origi...
