With the MKMapView there's an option called "Show users current location" which will automatically show a users location on the map. I'd like to move and zoom to this location when it's found (and if it changes). The problem is, there doesn't appear to be any method called when the user location is updated on the map, so I have nowhere...

I've been trying to figure out what happens in the view hierarchy when methods like pushViewController:animated, presentModalViewController:animated, and tab switches in UITabBarViewController are used, as well as UIAlertView and UIActionSheet. (Side note: I'm doing this because I need to know whether a specific UIView of my creation is...
Hi All, I'm trying to animating across the screen a horizontal bar with a color gradient. For simplicity, I chose to make a png of the fully extended bar, assign it to a UIImageView, and (attempt to) animate resizing of it using a UIView animation. The problem is that in the "closed" state of the Image, the portion of the image showing ...
So I have a bunch of UIViews that I made programmatically and placed a bunch of content on (UIButtons, UILabels, UINavigationBars, etc.), and most of these views are going to need to actually be UIScrollViews instead. Now keep in mind I made all these through code not the Interface Builder. What I first tried was to just change each dec...

So we want to be able to stream a video from a website. We also want to be able to do the same with a separate audio file. The reason why we need them to stream separately and can't integrate the two into just a video is because we need the user to be able to scrub the video however the audio should keep playing. Is there a way to get ...
So I have a UIViewController (main application controller is a TabBarController). On this there is a UINavigationBar, and a UIBarButtonItem. I'm PRETTY sure I hooked up everything correctly in the Interface Builder and that the outlet in the code is connected to the button in the .xib. It should be because the method works correctly. No...

All of a sudden, the visual design window disappeared from my Interface Builder. It is a regular UIView, has some UIImageView, UILabel, and UIButtons on it. When I open IB, I can see the document window (with File's Owner, First Responder and View in it), Library and Inspector, but the visual design window disappeared. Double click on "V...
I've got a view in my app that does pretty much everything, and I like it that way. The problem however is that it's implementing 5 or 6 different delegates, which seems a little bit messy. My question is, does the view controller have to implement all of the delegates? or is there some way I can separate the code out into different fil...
It's either because of the fact I'm tired or because I'm doing it wrong, but for some reason I can't get it to call a method. Here's what I'm trying to call: -(void)newHighScore:(int)d Which right now just does an NSLog saying "yea I'm working!" I'm calling it like this: [highscore newHighScore:score]; highscore is what I called ...
