I've seen at least one application that uses a grouped UITableView with a cell containing paragraphs of text, and the cell is taller or shorter based on the length of the text, but I don't quite get how this is done. How does one, given a variable width font, figure out how high a UITextField or something needs to be in order to display...
Sometimes when I program for the iPhone, I wonder when you have to allocate and initialize objects and when not to. When you are using UI controls, it seems as if you don't have to do so. Is this true and why? (Assume that they have been declared in the .h of the view controller.) Example: label1.text = @"Hello"; vs label1 = [[UILa...
Hi, I'm experiencing issues when converting decimal to currency for Korean Won, Cambodian Riel and Iranian Rial and showing the result to the UILabel text.

Hola! I have an issue I thought I would throw out to the S.O. world before I spent a lot of time on it.

Normally for something like this I would use a...
Hi, I have a UILabel that displays the current date for the current view of my scroll view. When I scroll this view to the left (to the left pages), I'd like this label to change to the day before, with a crossing effect between the 2 dates. I take as reference the fading effect of the Springboard when you scroll to the Spotlight page....
I'm adding a UILabel to each cell in my table view. This presents no problem innitially. When I round the corners of the UILabel using layer.cornerRadius scrolling the table view grinds to a halt. UILabel *label1 = [[UILabel alloc] initWithFrame:CGRectMake(cell.bounds.origin.x+10 ,5, 30, 30)]; label1.backgroundColor = ([[managedObjec...
I'm trying to sum the integers from five UITextFields and post them to a UILabel. This is the code I have tried, but it doesn't work properly. The number that shows up in the label is not the sum of my textfields. I have also tried to post to a textfield instead of a label, with the same result. No errors or warnings when I build. int ...

Since the image will be constantly changing, the color of the label's te...
