I randomly get this error, and I can't figure out a way to fix it: the variables pane (top right) is blank, and the gdb "po" command can't print any variables. The "po" command doesn't even know about "self": The problem appears specifically for all methods in the MGMinimap class. Nowhere else. I can debug from A and see self and th...

I've got a window with a UITabBarcontroller at the bottom. I have 3 tabs, corresponding to their respective views. Everytime I switch to a view via tapping on the tab, i want it to reload. Which event do I need to tap into? Where would I do this? thanks! ...
I know .xcdatamodel is actually a directory with two files (elements and layout). I know the two files are binary plists, and can convert them to XML plists with plutil -convert xml1 (while relying on this may be "unwise", it's perfectly fine for development: I expect that the build tools will compile/optimise/whatever when putting them...
Can any one tell me what the difference is between the isKindOfClass:(Class)aClass and the isMemberOfClass:(Class)aClass functions? I know it is something small like, one is global while the other is an exact class match but I need someone to specify which is which please. ...
I am using a UINavigationController to slide from a UITableViewController to another view. In that second view I have created a custom "Back" button which is attached to an action.

I'm at my wits end. I'm trying to debug a crash, and finally I manage to track it down. My 'minutesLeft' variable is somehow being released. Problem is, I never set it to release, and the property is set to retain. I can't figure out what is going on! Using the zombie variable, I got the following message: * -[CFNumber intValue]...

I'm just looking for advice with this as I have no idea where to start but I think a UIActionSheet is probably best. What I'd like to have is a pop up window (in my head I picture it as being translucent and dark gray). It will not take up the whole screen and the view underneath will still be visible. In the pop up section there will...

I have a UIView which has a bunch of subviews. The subviews should be able to receive touch events, but for some reason the parent UIView takes the touch and does not pass it on. I have created it in a very standard way like I always create views: UIView *myView = [[UIView alloc] initWithFrame:CGRectMake(0,0,1024,768)]; self.mainVi...

2nd edit: Already found the answer: UINavigationController has an option to show a toolbar and this video showed me how to substitue UINavigationController's standard slide animations by something different. Hi all, I'm trying to make an app that uses a navigation bar (top) and a toolbar (bottom) that can swap views in and out and putt...

I have an NSMutableArray which has about 18 objects. They are in a specific order that I want. I have to add these objects into an NSSet to be saved in Core Data. But, once I pull them out of the NSSet using [myObject.items allObjects] it does not keep the original order that I added the objects as. How can I keep the order that I ...
