I'm trying to add a UIButton with code (not Interface Builder). Some examples say you MUST alloc and release memory for the button. Others use buttonWithType and magically create a button without alloc'ing any memory at all. How is that possible? (Both seem to work fine.) Which of the 2 methods do I want to use... and when? Are th...
I have custom UITableViewCells (created in interface builder) which are used for a static UITableView which for the sake of argument I will call the AddUserTableViewController (i.e. I do not use autoreleased cells as I only have 5 rows). In the top cell (used for the user name) I have embedded a UIButton which I use to open an UIActionS...

Hi. I want to make a "Buy Now" button in my Application, which should work the same way as the one in the App Store, but I dont know how to resize the UIButton with an animation.

I would like to add a drop shadow to a UIButton. I tried to use self.layer.shadow* properties. Those properties work in UIView, but they behave differently in UIButton. I would really appreciate it if I could get any pointers to draw the drop shadow. Thank you! self.layer.cornerRadius = 8.0f; self.layer.masksToBounds = YES; self.layer.b...
Hi, Could somebody show me how to get the x and y position of a UIButton in cocoa? The button moves on the screen when clicked and I want to use it's current position to position another UIBUtton relative to it.

Ola Folks, Once again, I want to leech experience, information and knowledge from those who have more of them than I do.

Because the image is supposed to represent p...

Hi, I want to customize my UIBarButtonItem's appearance.

I know the b...
For some reason, the button initialized in the addBook method of my viewController won't respond to touches. The selector I've assigned to it never triggers, nor does the UIControlStateHighlighted image ever appear when tapping on the image. Is there something intercepting touches before they get to the UIButton, or is its interactivity...

I have a UINavigationBar with a custom UIBarButtonItem (which uses a UIButton as its custom view). The problem is: the active area of the custom button is much too large, if I tap at least 40 pixels outside the button, it still gets registered as a tap on the button. This results in accidental taps. How can I reduce the active area on th...
