I have a ordinary UITableViewController inside a UINavigationController. The former includes a searchbar which is connected to a search display controller. I use the standard behaviour, i.e. when the user enters any character the search results table view overlays the normal table view. Now, both table views act inside a navigation cont...
For instance: Create a new UIVC using initWithNibName, using "nib-v1" Display it, e.g. using [(UINavigationController) nav pushViewController: myVC] Change the NIB that myVC is using to "nib-v2" So far as I can see, this is the "correct" approach to app-design for a lot of apps, when paging through information where you need two slig...
Hi I have found a set of great macros here Objective C Macros I put the: #if DEBUG==1 #define .... macros in my header file. Now I simply can't figure out where to set DEBUG=1 or DEBUG=0 in Xcode so that it will define the macro when debugging and not when releasing. Hope someone can help me find the missing drop down menu:) Thank...
I really can't wrap my mind around this: Previously I couldn't get Framebuffers to work, but I've got it going now. However, there is this incredibly weird mirroring going on with the texture generated from the framebuffer, and I have no idea why. Basically, I will try to draw a texture at 0,0 using GL_TRIANGLE_FAN, and the texture appe...
I have a UITableViewController managing a grouped tableView. The tableView is populated from a fetchedResultsController. If I click the Edit button in the NavigationBar, then select a row and click the Delete button, the row is deleted and all ends well. However, if I swipe to reveal the Delete button in a row and click the Delete bu...

I am trying to build some code that is originally target at OSX/BSD/Linux for the iPhone. It uses struct rt_msghdr from route.h but as it turns out this header is not available in the iPhone SDK. Looks like the function tries to find the available bind addresses as a list of struct addrinfo. Does anyone have a suggestion how to proceed...
I am getting an error message displayed below when my button is pressed. I do not yet have any code inside my "buttonPressed" method although I don't think that has anything to do with it?

Hi all, I have an iPhone app (Objective C++). My beta testers - some of them, not all of them - are complaining of slow startup, 7 to 10 seconds. On my device (it's a 3GS), it loads in about 2 sec. On the device simulator - even faster. As things stand now, I cannot even isolate the bottleneck. Can I somehow slow down the simulator or ...

From reading the memory management docs in the SDK, I gathered that factory methods (static constructor methods) would typically be retaining the object for me and adding it to the autorelease pool? This would mean I have no need to retain & release an object as long as the pool does not get released before I expect? (Which should be at...

Hi all, Does anyone have any idea on how to make a path drawing to "link" up two buttons like the iphone game Airline Conqueror? ...
For my app's graph (line plots) it does not make sense to format the axis labels to tenths. It did not look like there was a way to change this without providing custom labels. I was able to add custom axis labels based on the sample code in this answer, but the labels do not have tick marks. Is this an issue (I didn't see anything...

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...
