I've always been baffled about the strange coupling in the iPhone API -- in particular, with the UIViewController, which has hard-coded references to a UITabBarItem, UITabBarController, etc. So, you end up adding a UIViewController to a UITabBarController, which in turn queries the UIViewController as to what should be displayed on the ...
When creating a UIView with a navigation bar in interface builder, the top bar takes some space, but the view still has the same size. This mean that the bottom of the view is not visible. Is there a way to get the "visible size" of a UIView? I would like to show a subview at the bottom of the screen, but part of the subview is hidden...
I've been trying to preserve the state of my iPhone application by serializing my main UITabBarController using [NSKeyedArchiver archiveRootObject:toFile:], but I'm running into difficulties. First I had a problem with UIImage, since it doesn't implement the NSCoding protocol, but I solved that by making an extension category for UIImag...

I'm creating a KVC/KVO-compliant mutable array on one of my objects the recommended way: @interface Factory { NSMutableArray *widgets; } - (NSArray *)widgets; - (void)insertObject:(id)obj inWidgetsAtIndex:(NSUInteger)idx; - (void)removeObjectFromWidgetsAtIndex:(NSUInteger)idx; @end Clearly this is a tricky thread-safety issue. In ...
I'm having problems with my application receiving low memory warnings while the user is deep within a navigation controller stack of views. After the user browses through a bunch of hierarchical options in subsequent UITableViews, he can open a PDF document in a UIWebView (in a different view controller). Everything works fine, the PDF ...
Hiya, I'm having quite a bit of pain inserting and deleting UITableViewCells from the same UITableView! I don't normally post code, but I thought this was the best way of showing where I'm having the problem: - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { return 5; } - (NSInteger)tableView:(UITableView *)t...
Hey folks, I have a ton of repeating code in my class that looks like the following: NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:self]; The problem with asynchronous requests is when you have various requests going off, and you h...
I have an odd edge case right now in that a response code from an NSURLConnection delegate method: - (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response; Is triggered before the subsequent delegate method: - (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data; My code...

(I believe that whether the array is mutable, or just replaced entirely, doesn't make a difference.) Access to the array itself is threadsafe. What's the proper way to ensure thread safety with regard to the tableview? I'm wo...

I am looking for a way to slide a UIPickerView (and UIDatePickerView) up over a view (UITableView in particular) when a particular button press takes place. I understand how to get the events for clicks into the UITableView, but there doesn't seem to be a good way to have the UIPickerView slide up on top of it... All the examples I hav...

Please pardon my lack of Photoshop skills, but I'm curious what type of strategy Apps like Facebook and AP Mobile News are using for the 'label slider' in their applications. Here's a quick snippet outlining what I'm talking about as I'm sure the name I'm labeling the utility as is being butchered: http://dl-client.getdropbox.com/u/57676...
