I am tired try open a modal view controller from ipad application.
How I can show a modal view like formsheet?
here my code block.
like this style opening a window (full screen) but there is don't have any object from my modal view
viewDetail *hd = [[viewDetail alloc] init];
UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:hd];
hd.modalPresentationStyle = UIModalPresentationFormSheet;
[self.navigationController presentModalViewController:nav animated:YES];
[hd release];
[nav release];
just i want open a formSheet modal view when selected a value from UITableView
by the way, i am development on xcode 4.2.1 and usind storyboard features
thanks for help.
like that give a SIGABRT error
viewDetail *hd = [[viewDetail alloc] initWithNibName:#"viewDetail" bundle:nil];
UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:hd];
hd.modalPresentationStyle = UIModalPresentationFormSheet;
[self.navigationController presentModalViewController:nav animated:YES];
[hd release];
[nav release];
I fixed my solution, worked a xib file out of story board.
But why wasn't it working in storyboard? There is a way for that?
If you're using storyboards, you have to set [self.storyboard instantiateViewControllerWithIdentifier:#"viewDetail"]; as your viewDetail View Controller. (Assuming you set the Storyboard Identifier accordingly)
hope that helps.

In my app, the rotation works fine in iOS7 but not working in iOS8.
As you can see, the status bar rotates, but the view controller does not.
I found the issue is caused by main storyboard setting, but I have no idea why it cased the issue. I just removed main storyboard setting in project file and everything works fine in iOS8.
Following is my codes to load storyboard.
[self setMainStoryboard:[UIStoryboard storyboardWithName:#"MainStoryboard-ipad" bundle:nil]];
UIViewController *vc = [mainStoryboard instantiateInitialViewController];
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// Override point for customization after application launch.
[self.window setRootViewController:vc];
self.window.backgroundColor = [UIColor whiteColor];
[self.window makeKeyAndVisible];
Maybe I used the wrong way to load storyboard?
I fix the problem, but I think this might not be a good solution. It's just a workaround. Anyway, here is what I have done. If you run into the same problem, you can try removing main storyboard setting in your target.
That's it, no further steps. Everything is fine after I remove main storyboard setting. Maybe the way I load main storyboard is incorrect or there is something wrong with my setting of storyboard.
Following is the codes I used to load storyboard:
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"Storyboard" bundle:nil];
UIViewController *vc = [storyboard instantiateInitialViewController];
UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:vc];
// Override point for customization after application launch.
[self.window setRootViewController:nav];
self.window.backgroundColor = [UIColor whiteColor];
[self.window makeKeyAndVisible];
If anyone know the correct way to use main storyboard, please give me some feedback. Thanks!
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.
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
In a view of my program I have a button and with this button I open a subview; this subview is a view with a tableview. I want go to another view when I push a row of the tableview so I want to make this with a navigation controller; how can I do this?
Your table view delegate will receive a tableView:didSelectRowAtIndexPath: message when you click on one of the table's rows.
You can put there your code to create the UINavigationController and push on to it your new view.
This sample code (from another answer of mine on S.O.) shows how you can do that:
UINavigationController* navigation = [[UINavigationController alloc] init];
iVkViewController *overviewViewController = [[iVkViewController alloc] init];
overviewViewController.title = #"First";
[navigation pushViewController:overviewViewController animated:NO];
This should help you getting things on track.
One side note: you might think of having a navigation controller from the very start, this would make your UI more "well-behaved", but this depends ultimately on your app requirements.
If UIViewController addSubView a view of UITableViewController,you want to push in the method of tableView:didSelectRowAtIndexPath,you should check if self.navigationController is nil. If it's nil,You probably should use
[self.parentViewController.navigationController pushViewController:controller animated:YES];
if self.parentViewController is also nil,Sometimes,you have to set a #property to point out the parentViewController In UITableViewController,like:
#property (nonatomic, weak) UIViewController *parentVC;
and in UIViewController:
UITableViewController *tableViewVC = [[UITableViewController alloc] init];
tableViewVC.parentVC = self;
In UITableViewController ,-tableView:didSelectRowAtIndexPath:
[self.parentVC.navigationController pushViewController:controller animated:YES];
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:
