I recently began trying my hand at using protocols in my Objective-C development as an (obvious) means of delegating tasks more appropriately among my classes. I completely understand the basic notion of protocols and how they work. However, I came across a roadblock when trying to create a custom protocol that in turn implements another...

Similar to the Simon games of old, I want to show the user a button sequence & then have them repeat it back. The place I'm stuck is showing the first button highlighted for, say, 500ms, waiting 100ms, showing the second highlighted for 500ms, waiting another 100ms, showing the 3rd & so on. From other Stackoverflower'ers I've gotten to...

This question has probably been asked before, but my google-fu must be inferior to everybody else's, cause I can't figure this out. I'm playing around with the iPhone SDK, and I'm building a concept app I've been thinking about. If we have a look at the skeleton generated with a navigation based app, the MainWindow.xib contains a naviga...
Basically I'm downloading images off of a webserver and then caching them to the disk, but before I do so I want to mask them. I'm using the masking code everyone seems to point at which can be found here: http://iphonedevelopertips.com/cocoa/how-to-mask-an-image.html What happens though, is that the image displays fine, but the version...

I have a UIToolbar that needs three buttons in a radio style, meaning that of the three, only one button can be pushed at a time. The documentation makes reference to the possibility of setting up radio UIBarButtonItems in the class reference definition of the width property: If this property value is positive, the width of the co...

I am implementing a view similar to a Table View which contains rows of data. What I am trying to do is that after scrolling, each row snaps to a set of correct positions so the boundaries of the top and bottom row are completely visible - and not trimmed as it normally happens. Is there a way to get the scroll destination before the sc...
Is it possible to read the name of an UIImageView's image that's presently stored in the ImageView? I was hoping you could do something kind of like this, but haven't figured it out. NSString *currentImageName = [MyIImageView getFileName]; ...
After rendering a UITableView with a given datasource, I want to be able to switch to a different one prior to calling reloadData. Tried doing it in the method - (void)viewDidAppear:(BOOL)animated; but as far as I can see this isn't called when all the visible cells are rendered. By placing a breakpoint it seems as if nothing is act...
Adding an image to a UINavigationItem's titleView is pretty trivial, but when I push a new view on the stack it animates the UINavigationItem sliding off to the left, along with the titleView, and loads a new UINavigationItem. I can think of a number of ways to go about making that image stay put, but they all seem pretty hacky. Is the...
