viewcontroller

I have inserted a table view on my view controller and I was wondering how can I give the cells in the table view a gradient background? Can I edit each cell individually to give it a different color gradient background for each cell? For example, each cell is labeled after an index in the trainingLevels array, how could I make to where each has a different color gradient background? Here's my code: import UIKit class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource { var trainingLevels = ["Ball Handling", "Shooting", "Defense", "Advanced Drills", "Vertimax Drills",

The only solution I have seen was an answer to a stackoverflow question. I posted the link below. The answer I am referring is the 5th one. It seems that some users have some problems with the solution however. I don't know if there is another category to prevent two controllers from being pushed at the same time. Any tips or suggestions are appreciated. #import "UINavigationController+Consistent.h" #import <objc/runtime.h> /// This char is used to add storage for the isPushingViewController property. static char const * const ObjectTagKey = "ObjectTag"; @interface UINavigationController ()

I'm currently building an app with a modal view popping up that contains a WkWebView. When I want to upload an image within this modal view and the Photo Selection appears, the modal view just dismisses back to the view controller that fired it up. How can I prevent that? import UIKit class PostWindow : UIViewController { @IBAction func close(sender: AnyObject) { dismissViewControllerAnimated(true, completion: nil) } override func viewDidLoad() { super.viewDidLoad() // do stuff here let myWebView:UIWebView = UIWebView(frame: CGRectMake(0, 70, UIScreen.mainScreen().bounds.width, UIScreen

I've been trying to figure out how to hide and show iAds in my Spritekit Scenes. Currently I have it setup like this: ViewController.h #import <UIKit/UIKit.h> #import <SpriteKit/SpriteKit.h> #import <iAd/iAD.h> @interface ViewController : UIViewController <ADBannerViewDelegate> { ADBannerView *adView; } -(void)showsBanner; -(void)hidesBanner; @end ViewController.m #import "ViewController.h" #import <UIKit/UIKit.h> #import <iAd/iAD.h> #import "MyScene.h" #import <SpriteKit/SpriteKit.h> @implementation ViewController - (void)viewDidLoad { [super viewDidLoad]; // Configure the view. SKView *

I am making an IOS app where i am calling an API in viewDidLoad method of view controller. Now i want to reload the same view controller with the data that comes from server. How many ways are there to do this task and what would be the best way?? Please help me. Thanks!! JAY RAPARKA viewDidLoad method is called first time when UIViewController is first loaded and when it pop and then you reenter in it at that time viewDidLoad is called. So if you want to load the API only once then viewDidLoad is the best place to call an API. viewWillAppear called every time when you enter in that

I am new to Swift and I want to know how to dismiss the current view controller and go to another view. My storyboard is like the following: MainMenuView -> GameViewController -> GameOverView. I want to dismiss the GameViewController to go to the GameOverView, not to the MainMenuView. I use the following code in my MainMenuView: @IBAction func StartButton(sender: UIButton) { let storyBoard : UIStoryboard = UIStoryboard(name: "Main", bundle:nil) let nextViewController = storyBoard.instantiateViewControllerWithIdentifier("GameViewController") as! GameViewController self.presentViewController

I want to call a new view controller and remove the current view controller from the navigation controller stack. For example. I am in view controller A and I call B. Now I have in the stack A , B. Now I want to call C (from B). I want the stack to be A, C. Thanks. JohnK In the context of ARC, here's a possible solution: NSMutableArray* navArray = [[NSMutableArray alloc] initWithArray:self.navigationController.viewControllers]; [navArray replaceObjectAtIndex:[navArray count]-1 withObject:nextViewController]; [self.navigationController setViewControllers:navArray animated:YES]; As you can tell,

Using: Xcode 4.6 Storyboards ARC Model segue to SecondViewController I have an app that has the main ViewController that loads a new veiwController when the device is rotated to the right. When the app starts everything works great. If I rotate the device, then back which unloads the secondview controller, about 15-20 times the app is very slugish. I have narrowed down that it only happenes when the seconed view controller is loaded and only when i rotate the device a nunmber of times. I also have narrowed down that is is a memory issue. I installed an app that keeps track of the memory used

I am getting the following error when I am trying to push my notification controller dynamically. 2015-03-30 13:18:53.324 MyApp WatchKit Extension[79826:1951724] Took too long to show custom notification. Falling back to static. 2015-03-30 13:26:13.831 MyApp WatchKit Extension[79826:1957863] WatchKit error - unable to find interface controller class '_TtC26MyApp_WatchKit_Extension19InterfaceController' to instantiate I heard there might be a glitch, but as far as I am concern it is only occurring on the Xcode beta and not Xcode 6.2. I change the module regarding the notification storyboard to
