ios iphone objective-c navigation segue
Just Have an issue and a “miss” in my programming “capacity”. I’ve got a tableview controller with some data parsed from a json.

I’m new at this so thanks in advance for any help here.I’m just playing around with a little exercise in iOS and I have 2 different things calling the same routine.Each of these message calls passes along sender. One of these is a UIButton that calls when touchUpInside, one is a UISegmentedControl that calls when valueChanges.I need to handle the initial part slightly differently within the same method and i know that somehow I use sender.What I need to do is to ask if sender is a UIButton or if

iphone objective-c ios gui exit
I’m working in an application that loads a few remote jsons at startup. The application has been programmed to do certain tests on the incoming data to prevent invalid states and to detect possible human errors. However, I am not sure of how we should treat such situation at the GUI level – our initial idea was to display a “Oops there was an unexpected server error. We are working to solve this issue. Please, try again later.” popup to quit the application when the user hits an “Ok” or “Exi

ios iphone objective-c uitableview
I have UIViewController and UITableViewCell with UITextField and UIDatePicker. If I change the value in the first cell UITextField I change the value in cell 1 and 7. If I change the value in the second cell UITextField I change the value in cell 2 and 8. And after the scroll value from the first cell sometimes moves in a second. Why is this happening? For cell I created a separate class which is UITextField and UIDatePicker.My UIViewController- (NSInteger)numberOfSectionsInTableView:(UITableVie

ios objective-c xcode uiscrollview uitableviewcontroller
In my view I am using a UITableView that is controlled by a UITableViewController on the top half of the screen. The remaining screen is used for a UIScrollView that contains a view that is controlled by the main UIViewController. When I perform a pull down to refresh in the UITableViewController, (for some reason if the number of table entries is less than or greater than the initial load value, the UIScrollView in the main UIViewController’s frame gets changed to the screensize… Essentially

I’ve an observer pattern on the UI that checks what’s the status of an object that handles a server connection that’s trying to update a certain field on a database.The UI’s update method receives an object containing data pairs containing the information of what’s happening with the connection. The problem is that I’m getting tangled with a lot of ifs checking for different possibilities.- (void) update:(Bundle *)arg {if ([[arg getData:@”updatee”] isEqualToString:@”email”]){UITableViewCell *ema

So that I can navigate(push/pop) from one viewcontroller to other.I added a subview to the mainview of a single navigation controller.When I click the button near to the tabbar, it doesn’t get clicked and the tabbaritem button gets access and shows that tab.Th

I’d like to change the order of view controllers attached to a UITabBarController, within my Storyboard, without disconnecting all view controllers and reconnecting them in the desired order.My Question: Can this be done just via the Storyboard IB UI?DiscussionI’m looking for some inspector panel where I can move items up and down in that list of view controllers that feeds the viewControllers property on UITabBarController.I’ve got a lot of tabs and so I’m hoping to not have to disconnect every

iphone cocoa-touch interface-builder uitabbarcontroller
My tabBarController-based app has several tabs. Each has a custom viewController class, the only difference being the way the instance is initialized. Is there a way to make interface builder send the different tabs custom init parameters?Currently I’m doing the initialisation in viewWillAppear, but for a bunch of reasons it would make sense to do it in IB instead of in the code.Any suggestions?thanks, Kelso

But when I run i get:*

cocoa-touch uikit uitabbarcontroller uitabbaritem presentmodalviewcontrolle
I am wondering if there is a way to add an additional UITabBarItem to my exisiting UITabBarController. It doesn’t need to be in runtime.All I want to do is when hitting this button I want to presentModalViewController: over my actually visible ViewController, which should either be the TabBarController or its controllers. Hopefully this is clear enough, if not, feel free to ask.
