I have a .h file that that declares the array, and then I initialize the array using NSString *input = [[NSString alloc] initWithData:myData encoding:NSACIIStringEncoding]; arr = [input com...

I have an iPhone app which submits user entered data to a SQL database. It causes an error, either cuts off the data or enters "null" when special characters are used. Seems that apostrophes and question marks and periods are ok, but anything outside of that causes it to cut off the post or post nothing at all. My SQL Query to insert th...
Hi Experts, I'm using the three20 framework and added a TTListDataSource, but I want to change the hight of each Cell (optimal would be the high the text takes inside, so that nothing is cut). I changed some values at Three20UI/TTTableSubtitleItemCell.h to change the inner high is no problem, but the dividing line is not accordingly r...

I've talked to a lot of people recently who say they are expecting to stop writing native mobile apps and start writing web apps once HTML5 gets more fully baked in mobile OSs. I just finished my first HTML5 deep dive, and I'm not yet convinced. Will HTML5 work as a replacement development platform for native apps, or are there certai...

In one service i have developed, i am sending to user MMS, which consists of 6 images, in special order. To set images in correct order, and add formatting i have used SMIL, which have worked well on the range of devices. However, seems that iPhone is not recognizing SMIL at all.

I am working on drawing anti-aliased lines in OpenGL-ES on iPhone. I am using an approach outlined in iPhone 3D Programming, called "Rendering Anti-Aliased Lines with Textures". The basis idea is to iterate through the line creating a bounding rectangle for each line segment (pair of vertices). This bounding rectangle can be represented ...
I am working on the iTuneU Stanford iPhone course HelloPoly drawing assignment, and I am getting a call to my object's init routine when I don't expect one. The callback seem to indicate that the call is coming from _loadMainNibFile (after other calls). What I am trying to understand is why is my object being init-ed implicitly. The sour...

Given a UITableViewController with a UISearchBar, how does one change the 'No Results' text that appears in the table view (after any characters are entered) to something like 'Search by Name'? The reason is that the search in question is performed remotely (and has about a second delay), so I can only perform the search when the user se...
I have some png's that are now resources in XCode. I would like to replace the with other png's on the device after deployment. How do I do that, while still being able to work with them in XCode? I thing it should be "Documents" "Library" or "Settings" folder, but it is not so clear how to create them in xCode. (This is an internal a...
Probably really a rookie question here about xcode (for the iphone).. When I issue this command; NSString *externalData = [NSData dataWithContentsOfURL:[NSURL URLWithString: @"http://blah.com/userlist.txt"]]; I can see it's download from my webserver. How can I make this 1 line show in a label? I tried; label.text = externalData; [e...
