The only way I can appear to do this so far is to have an empty name and image for the UITabB...
Trying to use a nice 'back' arrow image, like that found in Apple's iPod app - when I add my 30x30 image it seems to squashed or scaled, as it looks tiny? Is it possible that the UINavigationBar's back item will have to be custom view perhaps? ...
I am referring to the popup window that asks the user to submit a review/rating. I know it can be done since the Aardark app does it...it asks several times in fact! (Almost too spammy.) But there has to be an API to trigger the rating request? Google is giving me no love on this one. ...
For a personal project of mine, I'm trying to retrieve iPhone WiFi signal strength. I'm fully aware that this in the land of undocumented goodness, so please refrain from the "No Appstore" answers. :) Anywho, I've been reading up on previous WiFi Network Scanner Apps (WiFi Stumbler), but I'm afraid most (if not all) reflect outdated SDK...

If i am palying a sound using the AVAudioPlayer in the AVFoundation framework (I can already do this), is there any way to detect the current level of the audio playing, like a VU meter that is listening to the mp3 playing.

Hi guys, I have an application that loads core data, then calls the XML Web Service to get updated data. I basically want my app, rather than to erase all the data and load everything (including new) to persist, I want it to add only the new stuff onto the existing stack (without duplication). What's the general consensus strategy for ...

How can I align my UIView so that it aligns to the bottom of parents frame? Normally I would create it and move to the bottom of the view, in a full screen view that is 460px tall: myView = [[MYView alloc] initWithFrame::CGRectMake(0.0f, 300.0f, 320.0f, 160.0f)]; But how can I set this up so that if the available space for my iPhone ...
Hi, I'm wondering if I can change the background color of just the prompt of the UINavigationBar (e.g. to red, while the rest of the navigation bar stays black), so I can use the prompt property of the UINavigationItem to display status / error messages as a one-liner. Your help is appreciated. ...
Hi. I'm realizing what a newbie I still am with this problem I have. I am trying to present a modal window in a project I am working on and it's not appearing.
