side menu template contain this files:
1)JWSlideMenuController
2)JWNavigationController
3)JWSlideMenuViewController
Here the throw error

If hide this code from JWNavigationController.m so searchDisplayController is working
rootViewController.navigationController = self;
but new problem is UITableVIew didselectrowatindexpath is notworking .. what can i do?

isNavigationBarHidden: is a selector which is only available in classes that derive from UINavigationController. You have to modify this line:
#interface JWNavigationController : UIViewController
with this:
#interface JWNavigationController : UINavigationController

Your JWNavigationController does not inherit from UINavigationController.
But, isNavigationBarHidden is a method implemented by UINavigationController.
Now look at the error (which uses the term 'selector', but that refers to the method): It basically says that the instance of your JWNavigationController does not implement isNavigationBarHidden, and this is the issue.
Could it be that you mistyped, and meant to write:
#interface JWNavigationController : UINavigationController <UINavigationBarDelegate>

How to dismis Viewcontroller (popup) by pressing button inside my popup viewcontroller and also touch any where outside of viewcontroller?

I have one viewcontroler with one button.When i press that one pop up viewcontroller will show up.And when i touch anywhere outside it dismiss the viewcontroller .And return to my main viewcontroller.
Note
I used my popup through one viewcontroller and i use identifier name .Then i show pop up using that storyboard identifier and declared in my viewcontroller.m in btnSelectDatePressed
Needed
in that pop up view controller i have one button when user press also it should dismiss the viewcontroller and should return to my main viewcontroller.My example image is like this sample image
This is my viewcontroller.m file

I am beginner in ios.Some one please give some solution for my problem.Thanks in advance !
I changed the code of UIViewController+ENPopUp.m for have a visible button.
In code existe a button with screen size for dismiss view. I changed this button and now he is visible.
In presentPopUpView UIViewController+ENPopUp.m where have this comment " // Make the background clickable" I change the code to this:
CGFloat buttonSize = 10;
UIButton * dismissButton = [[UIButton alloc] init];
dismissButton.backgroundColor = [UIColor redColor];
dismissButton.frame = CGRectMake((self.view.frame.size.width/2) - (buttonSize/2),(self.view.frame.size.height/2) + (self.view.frame.size.height/4) , buttonSize, buttonSize);
[overlayView addSubview:dismissButton];
[dismissButton addTarget:self action:#selector(dismissPopUpViewController)
forControlEvents:UIControlEventTouchUpInside];
This create a red button 10x10 like in figure:
Now, you can change the color and the size of button for what you want.
I hope this can help you.

Can't switch between 2 view controller's with a Segmented Control

I created a UISegmentedControl programmatically in the navigation bar of a UIViewController and I want to be able to switch view controllers when i toggle the segmented control.
This is what I have so far:
#interface TVExploreViewController : TVViewController
#property (nonatomic, strong) UISegmentedControl *scopeControl;
#property (nonatomic, assign) NSInteger scope;
#property (nonatomic, strong) UIViewController *premiumContentViewController;
#property (nonatomic, strong) UIViewController *trendingContentViewController;
#property (nonatomic, strong) UIViewController *currentViewController;
#end
TVExploreViewController's implementation:
- (void)viewDidLoad {
[super viewDidLoad];
_scopeControl = [[UISegmentedControl alloc] initWithItems:[NSArray arrayWithObjects:#"TV & MOVIES", #"VIRAL CLIPS", nil]];
[_scopeControl setFrame:CGRectMake(80, 0, 200, 30)];
[_scopeControl addTarget:self
action:#selector(scopeChanged:)
forControlEvents:UIControlEventValueChanged];
[[self navigationItem] setTitleView:_scopeControl];
[_scopeControl setSelectedSegmentIndex:0];
_premiumContentViewController = [[TVPremiumContentViewController alloc] init];
_trendingContentViewController = [[TVTrendingFeedController alloc] init];
[self setScope:0];
}
- (void)scopeChanged:(id)sender {
[self setScope:self.scopeControl.selectedSegmentIndex];
}
- (void)transitionToViewController:(UIViewController *)controller
{
[self.currentViewController willMoveToParentViewController:nil];
if (controller) {
[self addChildViewController:controller];
}
controller.view.frame = self.view.bounds;
[self.view addSubview:controller.view];
[self.currentViewController.view removeFromSuperview];
[self.currentViewController removeFromParentViewController];
[controller didMoveToParentViewController:self];
self.currentViewController = controller;
}
- (void)setScope:(NSInteger)scope {
if (scope != _scope) {
_scope = scope;
UIViewController *nextController = nil;
if (_scope == 0) {
nextController = self.premiumContentViewController;
} else if (_scope == 1) {
nextController = self.trendingContentViewController;
}
[self transitionToViewController:nextController];
}
}
When I toggle the segmented control in TVExploreViewController, the rest of the view stays white and no view controller is loaded. Anyone know what I'm doing wrong?
This is not an answer, but It is convenient to write some log code here.
Can you show me the log in the method ?
- (void)transitionToViewController:(UIViewController *)controller
{
[self.currentViewController willMoveToParentViewController:nil];
if (controller) {
[self addChildViewController:controller];
}
controller.view.frame = self.view.bounds;
[self.view addSubview:controller.view];
[self.currentViewController.view removeFromSuperview];
[self.currentViewController removeFromParentViewController];
[controller didMoveToParentViewController:self];
self.currentViewController = controller;
// can you show me the log here ?
NSLog(#"%#, %#, %#", controller.view, controller.view.superview, self.view) ;
// you should see the subviews that you added.
NSLog(#"subviews:%#", [controller.view subviews]) ;
}
It is really not a good idea to add Viewcontrollers to ViewController,you should always have one ViewController on screen. You could do this using NavigationController with pushing with no animation.

UITextField doesn't respond on iOS 7.1

I have an abstract class that is a UIView subclass.
It creates a view on a new UIWindow and shows my Custom alert to users.
I have an AuthorizationView class inherited from this abstract class and it contains some UITextFields.
The problem is: these UITextFields doesn't respond on iOS 7.1 beta if I build it now and send to testers.
Old versions of project work fine (from AppStore) on iOS 7.1 beta.
Any version works fine on iOS 6.0 - iOS 7.0. I have no possibility to test it myself on iOS 7.1 beta.
Any suggestions?

All the Event Delegate methods will touch the main Window of the application. Now you have created another window, may be your delegate is calling, but hiding because this new Window. Just make window color clear color and verify, or else try with printing text of Text Field entering some text, will let you know is triggered or not?

Programmatically navigate pages in UIPageViewController

I'm trying to implement an questionnaire app.
I have an UIPageViewController attached to the main view controller called QuizPageViewController.m. other controllers such as buttons are placed in content view controller called QuizContentViewController.m.
Now my question is how do I navigate pages of UIPageViewController programmatically from QuizContentViewController.m (eg. when buttonDoneClicked clicked)? I'm already aware of the fact that i can programmatically navigate pages using following command but my problem is I don't have access to its arguments from content view controller (QuizContentViewController).

If I understand your question correctly, the QuizContentViewController's view has buttons that are pressed and once pressed it needs to notify your mainviewcontroller so it can set the view appropriately on QuizPageViewController? If this is the case, protocols are a great way for viewcontrollers to send messages to other viewcontrollers. Here is apple documentation about protocols: Working with Protocols.
Protocols are a little tricky the first time you use them. Once everything is set-up correctly you should be able to do something like this:
-(void)buttonBackClicked:(id)sender
{
[self.delegate shouldMoveBack];
}

Refactor iOS ViewController to work without needing a nib

I wrote a nice gallery view controller .h .m and .xib that work fine for my purposes. Tap a programmatically created button and load an image, play a movie or view a pdf or website - while in an existing uinavigationcontroller. I want to change it so I can add the contents of the xib in code - without using the nib file. In this way it will be more useable (I think).
The problem is the functions in the .m that reference, for instance - [self presentMoviePlayerViewControllerAnimated:YES] etc do not work. I tried making a property of the rootviewcontroller in this new .h and .m and replacing self with myController (property name). But my view controller code relies on uinavigation existing to push new content or things like that. How can I remove/tweak these references to self or a reliance on uinavigationcontrollers so it will work like when it has a view controller for a nib?
Edit: Code added below. In the nib there is just a uiscrollview called uis_thumbScrollView. I would like to add this anywhere by simply calling something like:
[self.view addSubview:[[ebThumbScroller alloc] initWithFrame:CGRectMake(0, 0, 1024, 733)]];
Everyone's comments reminded me that the uiview this will be put in exists within the rootviewcontroller, over the top. Maybe this is why I can hear the movie playing - but not see it.
Note: The code creates a series of uiviews with buttons inside of a uiscrollview.

If your only problem is the not working [self presentMoviePlayerViewControllerAnimated:YES] method, the problem is that presentMoviePlayerViewControllerAnimated: requires the actual moviePlayerViewController as an argument not a boolean value. (assuming you're refering to this method of the UIViewController category) UIViewController MediaPlayer Additions Reference
So if you replace that by say presentMoviePlayerViewControllerAnimated:self.moviePlayerVC, it should work as expected.
I'm not sure I understand your question, but if you need to wrap your controller to some UINavigationController you can do it like this:
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:myController];
navController.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
navController.navigationBar.barStyle = UIBarStyleBlack;
[self presentViewController:navController animated:YES completion:^{
//
}];
later on any child controller will have the navigation hierarchy.
