Make AppDelegate's Navigation Controller accessible from DetailViewController of SplitView - xcode

My DetailView of a SplitView has a Map with Annotations. Upon clicking an Annotation the entire window (and not just the DetailView) should go to another view. Unfortunately that doesn't work.
This is how I'm creating my NavigationController in my AppDelegate
UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:self.viewController];
[self.window addSubview:navigationController.view];
This is how I'm creating the SplitView
left = [[MapSplitViewLeft alloc] initWithStyle:UITableViewStylePlain];
right = [[MapViewController alloc] init];
splitViewController = [[UISplitViewController alloc] init];
splitViewController.viewControllers = [NSArray arrayWithObjects:left,right, nil];
self.view = splitViewController.view;
left.right = right;
[left release];
[right release];
And that's what's being called when clicked on an Annotation:
- (void)showDetails:(id)sender {
NSLog(#"Yes it works");
VenueViewController *vviewcontroller = [[VenueViewController alloc]
initWithNibName:#"VenueViewController" bundle:[NSBundle mainBundle]];
AppDelegate *del = (AppDelegate *)[UIApplication sharedApplication].delegate;
[del.navigationController pushViewController:vviewcontroller animated:YES];
}
When I click on the Annotation I only get "Yes it works" but nothing else is happening.
Thanks so much for any advise.

Every UIViewController has the property "navigationController". Try with your current ViewController to push the new Viewcontroller.
[self.navigationController pushViewController:vviewcontroller animated:YES];
edit: Sorry, you mean the entire window! I think that would not work.
edit2: Maybe this answer can help you how to add a view over window in uiviewcontroller But i think thats that view is not on your navigationController-Stack

presentViewController in AppDelegate with delay in iOS8

So I had a full working solution in iOS7 that displays a LoginViewController via presentViewController in the AppDelegate's didFinishLaunching.
Basically I am doing something like this:
UIViewController *backgroundViewController = ...
self.window.rootViewController = backgroundViewController;
[self.window makeKeyAndVisible];
[self.window.rootViewController presentViewController:loginViewController
animated:NO ...]
In iOS8 I see a jump. First I see the backgroundViewController then after about 1 second or so the login appears.
So, how can I prevent this jump in iOS8?
I am seeing that are a ton of developers with this kind of problem but still didn't find a solution.
Also a hack (for now), but just one line of code
Add the view of the view controller you're presenting to the window before presentation
UIViewController *viewController = [[UIViewController alloc] init];
[viewController.view setBackgroundColor:[UIColor greenColor]];
// Temporary iOS8 fix for 'presentation lag' on launch
[self.window addSubview:viewController.view];
[self.window.rootViewController presentViewController:viewController animated:NO completion:nil];
If you are presenting a navigation controller than add the navigation controller's view instead of its top view controller.
I have a quick hacky fix:
//Make a screenshot of the ViewController first, or use a real image if you want
__block UIImageView *fakeImageView = [[UIImageView alloc] initWithImage:image];
fakeImageView.frame = vc.view.frame;
[self.view addSubview:fakeImageView];
[self presentViewController:vc animated:animated completion:^{
[fakeImageView removeFromSuperview];
fakeImageView = nil;
}];
It is not good for long term, but can quickly fix this issue without changing too much code.
Waiting for better solutions.
You can set the window to an instance of a temporary controller.
self.window.backgroundColor = [UIColor whiteColor]; //do some styling etc.
self.window.rootViewController = [LoginViewController new];
[self.window makeKeyAndVisible];
From the set controller (LoginViewController) you can push your real login controller with the desired transition. Once the login sequence is over you can make a transition from the login controller to the default application root view controller.
[UIView transitionWithView:[AppGlobal sharedApp].applicationWindow
duration:0.75
options:UIViewAnimationOptionTransitionFlipFromLeft
animations:^{
[AppGlobal sharedApp].applicationWindow.rootViewController = [AppRootViewController new];
} completion:nil];
I have also faced the same problem in iOS8 and I found this solution:
ABCViewController *obj = [[ABCViewController alloc] initWithNibName:#"ABCViewController" bundle:nil];
CATransition *transition = [CATransition animation];
transition.duration = 0.4;
transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
transition.type = kCATransitionMoveIn;
transition.subtype = kCATransitionFromBottom;
transition.delegate = self;
[self.navigationControler.view.layer addAnimation:transition forKey:nil];
[appDelegate.navigationControler obj animated:NO];
obj = nil;
I hope this solution can help you!
This should work:
call [loginViewController view]
Before presenting it.

Resize the UIViewController View

I am new in iPhone/Ipad Application development and Just learning the UIViewController, UIView etc with Xcode and while using uiviewcontroller want to resize but my tricks logic are not working. please let me know if you have any Idea with this.
Thanks
i think your are looking like this.
(IBAction)buttonPressed:(id)sender
{
menuView.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:#"bgground.jpg"]];// i used 1 view name is menuView
UIViewController *menu =[[UIViewController alloc] init];menu.view = menuView;
[menu setModalTransitionStyle:UIModalTransitionStylePartialCurl];
[self presentModalViewController:menu animated:YES];
[menu release];
}
After resize try this code
UIViewController* view = [[UIViewController alloc] init];
[self presentModalViewController: view animated: NO];
[self dismissModalViewControllerAnimated: NO];
[view release];

IBAction,button and camera

I have a button in my interface declared in .h file
#interface UserProfileVC : UIViewController <UIImagePickerControllerDelegate>{
IBOutlet UIButton *camera;
}
#property (nonatomic,retain) IBOutlet UIButton *camera;
-(IBAction)cameraPress:(id)sender;
And in my .m file i have:
-(IBAction)cameraPress:(id)sender{
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
// [picker setDelegate:self];
[picker setAllowsEditing:YES];
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
[self presentModalViewController:picker animated:YES];
[picker release];
}
But I have this error:
*** -[UserProfileVC performSelector:withObject:withObject:]: message sent to deallocated instance 0x7bc2a40
Can someone help me? I can't understand what is the mistake.
Thanks
As per the code from ur last comment,
-(void)showDetails:(id)sender{
NSLog(#"Annotation Click");
details= [[UserProfileVC alloc] initWithNibName: #"Details" bundle:nil ];
details.Nome=note.title;
addNavigationController = [[UINavigationController alloc] initWithRootViewController:details];
[self.navigationController presentModalViewController:addNavigationController animated:YES];
}
I can suggest you following.
If you look at the UIViewController class reference document, you will find below notes
presentModalViewController:animated:
Presents a modal view managed by the given view controller to the user. (Deprecated. Use presentViewController:animated:completion: instead.)
So I would suggest you to use presentViewController:animated:completion. I dont find it relevant to error "message sent to deallocated instance" but still check if u could solve your problem.
Also I dont know Why u wrote this line
addNavigationController = [[UINavigationController alloc] initWithRootViewController:details];
If you simply want to show UserProfileVC in the current UINavigationController then I would suggest you to remove addNavigationController line & write only
[self.navigationController presentViewController:details animated:YES completion:NULL];

trying to push a detail view when the right button is tapped on the annotation of mapview in xcode

i wanted to display the detail view after tapping the right button on the annotation of mapview in xcode but i could not get the view to display ,
my code:
- (void)showDetails:(id)sender
{
[self.navigationController setToolbarHidden:YES animated:NO];
[self.navigationController pushViewController:self.detailViewController animated:YES];
}
- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>)annotation
{
static NSString* BridgeAnnotationIdentifier = #"bridgeAnnotationIdentifier";
MKPinAnnotationView* customPinView = [[[MKPinAnnotationView alloc]
initWithAnnotation:annotation reuseIdentifier:BridgeAnnotationIdentifier] autorelease];
customPinView.pinColor = MKPinAnnotationColorPurple;
customPinView.animatesDrop = YES;
customPinView.canShowCallout = YES;
UIButton* rightButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
NSLog(#"%#",rightButton);
[rightButton addTarget:self
action:#selector(showDetails:)
forControlEvents:UIControlEventTouchUpInside];
customPinView.rightCalloutAccessoryView = rightButton;
return customPinView;//[kml viewForAnnotation:annotation];
}
The showDetails method gets called but cannot push the detailViewController to the top ,
[self.navigationController pushViewController:self.detailViewController animated:YES];
this code should have pushed detail view to the top and displayed the detailView but it does not please ,
any help would be greatly appreciated , what i wanted to do is when anybody taps on the right button of annotation on the mapview ,i wanted to display a detail view , thanking you in advance..
There is no target/action required, there is a delegate method that gets called when the callout accessory view is tapped: mapView:annotationView:calloutAccessoryControlTapped:
Thank you , for your help i am able to open the detailViewController by changing my showDetails method
- (void)showDetails:(id)sender
{
detailViewController *dvController = [[detailViewController alloc] initWithNibName:nil bundle:nil];
[self presentModalViewController:dvController animated:YES];
[dvController release];
dvController = nil;
}

UITabBarController + UINavigationController problem xcode project

I have a problem, I have created a project window based application in xcode, then I create a UITabBarController that manages two views all programmatically, the second view is a tableView and I want to see in the top a UINavigationController, I have tried a lot but I don't know how to have a UINavigationController in the second view. this is the code:
ProjectAppDelegate.m
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
//Creo una tabBarController
UITabBarController *tabBarController = [[UITabBarController alloc] init];
//Create the two view controllers
UIViewController *vc1 = [[Visuale1ViewController alloc] init];
UIViewController *vc2 = [[Visuale2ViewController alloc] init];
//Make an array containing the two view controllers
NSArray *viewControllers = [NSArray arrayWithObjects:vc1, vc2, nil];
//The viewControllers array retains vc1 and vc2, we can release
//our ownership of them in this method
[vc1 release];
[vc2 release];
//Attach them to the tab bar controller
[tabBarController setViewControllers:viewControllers];
//Setto la tabBarController come rootViewController di window
[window setRootViewController:tabBarController];
//The window retain tabBarController, possiamo lasciare il nostro riferimento
[tabBarController release];
[self.window makeKeyAndVisible];
return YES;
}
Visuale1ViewController.h
#implementation Visuale1ViewController
- (id)init{
[super initWithNibName:#"Visuale1ViewController" bundle:nil];
//Get the tab bar item
UITabBarItem *tbi = [self tabBarItem];
//Give it a label
[tbi setTitle:#"Visuale 1"];
return self;
}
// The designated initializer. Override if you create the controller programmatically and want to perform customization that is not appropriate for viewDidLoad.
- (id)initWithNibName:(NSString *)nibName bundle:(NSBundle *)bundle {
return [self init];
}
Visuale2ViewController.h
#implementation AnswerViewController
- (id)init{
//Call the superclass's designated initializer
/*[super initWithNibName:nil
bundle:nil];*/
[super initWithStyle:UITableViewStyleGrouped];
answers = [[NSMutableArray alloc] init];
for (int i = 0; i<10 ; i++) {
[answers addObject:[Answer DefaultAnswer]];
}
//Get the tab bar item
UITabBarItem *tbi = [self tabBarItem];
//Give it a laber
[tbi setTitle:#"Visuale 2"];
return self;
}
- (id)initWithStyle:(UITableViewStyle)style{
return [self init];
}
//All below are all methods to work the table view, and all go well, the only problem it's the UINavigationController, to manage then the detail of the table...
Now I want to know how I can put a UINavigationController in the second view. I try do this, in ProjectAppDelegate.m:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
//Creo una tabBarController
UITabBarController *tabBarController = [[UITabBarController alloc] init];
//Create the two view controllers
UIViewController *vc1 = [[Visuale1ViewController alloc] init];
UIViewController *vc2 = [[Visuale2ViewController alloc] init];
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:vc2];
//Make an array containing the two view controllers
NSArray *viewControllers = [NSArray arrayWithObjects:vc1, navController, nil];
//The viewControllers array retains vc1 and vc2, we can release
//our ownership of them in this method
[vc1 release];
[vc2 release];
//Attach them to the tab bar controller
[tabBarController setViewControllers:viewControllers];
//Setto la tabBarController come rootViewController di window
[window setRootViewController:tabBarController];
}
In this way I can visualize the NavigationBar, but I lost the name of the SecondTabBar. Sorry for my english, how I can do this?
Yes in the second view you have to set title as
[self.navigationItem setTitle:#"Visuale2"];
For TabBar title-
UITabBar *tabBar = [self.tabBarController tabBar];
NSArray *tabBarItems = [tabBar items];
UITabBarItem *secondTabBarItem = [tabBarItems objectAtIndex:1];
[secondTabBarItem setTitle:#"Visuale2"];
I left the code as it was and I added in init Visale2ViewController this:
UIImage *i = [UIImage imageNamed:#"Hypno.png"];
[tbi setImage:i];
and now in can see the text Visuale2 in tabBar and the image...i don't know why...
You need to set the tabBarItem property for your UINavigationController. Something like this.
UITabBarItem *tabItem = [[UITabBarItem alloc] initWithTitle:#"Visuale 2" image:nil tag:1];
UIViewController *vc2 = [[Visuale2ViewController alloc] init];
navController = [[UINavigationController alloc] initWithRootViewController:vc2];
navController.tabBarItem = tabItem;
After looking at it,the scenario seems to be same like me.What I faced for the first time when doing Tab+Navigation.
I am sure that there is some problem with your Tab+Navigation based application. Although it shows the Tab as well as navigation are not able to navigate the basic flow.And it is very difficult to solve your problem with such less code.
Instead of this, I had an alternate solution for the same:
Once you have a tab bar in a XIB, the easiest way to approach this is to drag a UINavigationController object over from the Library window (looks like a left nav bar button on a gold background) into the Tree View for your tab bar (the text only view, not the GUI). Place it under the tab bar, then drag your existing view controller under the tab bar controller instead of under the tab bar.
When you go to view that tab you should then see a navigation bar on the top of it... if you are loading the navigation controller from another xib, you'll modify the nav bar in the tab bar xib.
else you can below you can follow the best url for the same:
