I have a project that needs to incorporate two third-party libraries, libA and libB. I have little, if any, influence over the third-party libraries. The problem being is that both libA and libB include different versions of a common library, ASIHTTPRequest. As a result, I'm getting errors like: -[ASIFormDataRequest setNumberOfTimesToRe...

I am using a NSSearchField to run a query over the internet and display the results in a table view. Whilst the query is running I would like to display a progress indicator inside an NSSearchField? I think I have seen this done in another application before. Is there an open source component that I could use to accomplish this? How wo...

Then i make 3 rectangles (imageRect, secRect and IntersectRect), the imageRect is the rect which show an image, secRect is rect which just act to darken whole imageRect, and the intersectRect is a rect which like an observe rect, wha...
How exactly does one go about implementing a custom toolbar for the main table view section of a split view? The program I am writing for the iPad is landscape only so the split view has a static table view along the left side, and at the top is the toolbar with a title. It is this toolbar I would like to change. I have created the spl...

I'm reading through Mark Dalrymple's Learn Objective-C on the Mac (only at the chapter on Protocols, so still relatively newbish) and trying to figure something out: Why would you ever reference a class by its own name? If I had a class called Foo, why would I ever want to write, say, [[Foo alloc] init] and not [[[self class] alloc...

For example, I want @property NSString* title and @property NSString* author. For each one of these properties, the implementation is the same: for the gette...
Hi, I have a UIView with a NIB. The view in the NIB is set to 280 x 390.

I'm displaying an MJPEG stream in a UIWebView. I have two different sizes I want to use for the UIWebView. The video size is constant. So setScalesPageToFit isn't flexible enough, and I have no control over the source to change the viewport meta tag. So I'm left thinking that I need to do this via javascript (of which I have very lit...
(This is both question and answer since it took quite a bit of digging to find the real answer.) Symptom: viewWillAppear, viewDidAppear were not being called in my UIViewController. Cause: Embedding a UINavigationController or UITabBarController (my case) in a UIViewController somehow interrupts with the calling of these methods. Sol...
