I tried to add to the plist this row :
View controller-based status bar appearance" setter to NO .
Still see the status bar.
How can i remove it ?
Set this in your AppDelegate and remember to set "Status bar is initially hidden" to YES in your info .plist
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
[[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation:UIStatusBarAnimationNone];
return YES;
}
Try this. In your appDelegate do this:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
[[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation:UIStatusBarAnimationNone];
return YES;
}
Hope this helps.. :)

I have a workspace with MFSideMenu. One voice of this menu has 3 UIViewController I would scroll with UIpageControl. it's possible?
How can it work?
Thanks
Basic example:
In your app delegate
#import "MFSideMenu.h"
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Do other stuff
MFSideMenuContainerViewController *container = [MFSideMenuContainerViewController
containerWithCenterViewController:centerViewController
leftMenuViewController:leftMenuViewController
rightMenuViewController:rightMenuViewController];
self.window.rootViewController = container;
[self.window makeKeyAndVisible];
}
For more information:

Inside AppDelegate.m I am trying to grab the stuff from a string I am getting from an incoming URL. I'm not sure why NSLog is not printing anything out...
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions openURL:(NSURL *)url
{
// incoming URL...
// i.e. palsvid://blabla.com/foo.php?request=laa&id=1004
NSString *q = [url query];
NSLog(#"%#",q); // Does not log anything! Even with a hard coded string!
NSArray *pairs = [q componentsSeparatedByString:#"&"];
// ...
Am I doing something wrong? I update plist to accept the url, now I want to parse it.
Eventually I will take this data and use it in my ViewController. NSLog works in the ViewController methods...
Thanks
You have the wrong method signature so your method is never called. There is no openURL: parameter. You want:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// your code here
}
That is called when you app is started from scratch.
To handle your app being called from another app or being sent a URL, you need to implement the following:
- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation {
// process URL here
}
Please read the docs for UIApplicationDelegate as well as the related app life cycle docs.
I want to catch the event when someone switches between tabs. I have the following two function in my appdelegate file:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
UITabBarController * uitbc = [storyboard instantiateViewControllerWithIdentifier:#"tabbarcontroller"];
uitbc.delegate = self;
[self.window addSubview:uitbc.view];
return YES;
}
- (void)tabBarController:(UITabBarController *)tabBarController didSelectViewController:(UIViewController *)viewController
{
NSLog(#"switching");
}
But the NSLog(#"switching"); never fires. The xcode issues a warning for the line uitbc.delegate = self; saying "Passing appdelegate const__strong to parameter of incompatible type id".
What am I doing wrong? I'm just following the accepted answer found here, except i'm instantiating my tabbarcontroller form story board:
how to get the event that switch tab menu on iphone
Update
Based on skram's suggestion, I wrote this for my appdelegate but the NSLOG(Switching) still doesn't fire:
#interface johnAppDelegate : UIResponder <UITabBarControllerDelegate>
I also updated my didFinishLauchingWithOptions:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
tabBarController = self.window.rootViewController.tabBarController;
tabBarController.delegate = self;
[window addSubview:tabBarController.view];
}
Good thing is that nothing crashes. I also no longer et the warning about incompatible types. But still, didSelectViewController doesn't fire.
in my appdelegate.h file, I changed the line
#interface wscAppDelegate : UIResponder <UIApplicationDelegate>
to
#interface wscAppDelegate : UIResponder <UIApplicationDelegate,UITabBarControllerDelegate>
Then in my CustomTabBarController in the viewDidLoad function i added these lines:
wscAppDelegate *appDelegate = (wscAppDelegate *)[[UIApplication sharedApplication] delegate];
self.delegate = appDelegate;
Then in appdelegate.m file, I added this function
- (void)tabBarController:(UITabBarController *)tabBarController didSelectViewController:(UIViewController *)viewController
{
NSLog(#"hooray this works");
}
I also struggled with this a lot but my UITabBarNavigationController is pretty far from AppDelegate to set it there, and the only way to actually make it work was to do it not in the viewDidLoad of the UITabBarController subclass itself, but in its:
-(void)viewDidLayoutSubviews {
[ super viewDidLayoutSubviews ];
self.delegate = self;
}
And that solved it. Alternatively you can do it in any of the tab bar controlled viewcontrollers, but that just feels wrong.
You need your AppDelegate to conform to UITabBarControllerDelegate protocol. See below..
#interface YourAppDelegate : UIResponder <UITabBarControllerDelegate>
I'm new to iOS and Objective-C. I have an application that displays a table view, and opens a new view when click the user clicks on a row.
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
[tableView deselectRowAtIndexPath:indexPath animated:YES];
DetailViewController *detailController = [[DetailViewController alloc] initWithNibName:#"DetailView" bundle:nil];
[detailController changeSubjectText:[subject_data_Array objectAtIndex:indexPath.row]];
//navigationController = [[UINavigationController alloc] initWithRootViewController:detailController];
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
[self.window addSubview:navigationController.view];
[self.window makeKeyAndVisible];
}
In my detail view I have coded:
-(IBAction)closeDetail:(id)sender {
NSLog(#"closeDetail");
[self.view removeFromSuperview];
}
But it's not working. Can anyone help?
Can anyone help me?
how i can close view?
download my code in --> http://www.vasuta.com/ios/multiview2.zip
open build and run click one row in "Bulletin Board" DetailView it's open click Close …..
why DetailView is not full screen and why can't close detail view?
i open it wrong or i close it wrong
help me please
didSelectRowAtIndexPath you can see in "GadgetBulletinsTVContoller.m" and close command you can see in "DetailViewController.m"
Thank you very much
ps. sorry for my english skill :(
Why are you creating that window object and why are you trying to add your subview to it?
if you want to add a subview you should add it to the parent, the tableview or the parent of the tableView.
a better idea would be to push a new view controller on the stack that would display the info you want to show.
Here is a tutorial that shows how to push a new view controller when selecting a cell in a tableview tutorial link .
EDIT:
in MultipleAppDelegate - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions should look like below:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// Override point for customization after application launch.
self.viewController = [[MultipleViewController alloc] initWithNibName:#"MultipleViewController" bundle:nil];
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:self.viewController];
navController.navigationBarHidden = YES;
self.window.rootViewController = navController;
[self.window makeKeyAndVisible];
return YES;
}
In GadgetBulletinsTVContoller.h declare a protocol like below:
#protocol GadgetBulletinsTVControllerDelegate <NSObject>
#optional
- (void)showItemDetails:(id)selectedItem;
#end
and a delegate property:
#property (nonatomic, assign)id<GadgetBulletinsTVControllerDelegate>delegate;
In GadgetBulletinsTVContoller.m synthesize the delegate.
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
should look like this:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
[tableView deselectRowAtIndexPath:indexPath animated:YES];
if([delegate respondsToSelector:#selector(showItemDetails:)])
{
[delegate showItemDetails:[subject_data_Array objectAtIndex:indexPath.row]];
}
}
In FirstViewController.m tell the controller to implement the GadgetBulletinsTVControllerDelegate like this:
#interface FirstViewController ()<GadgetBulletinsTVControllerDelegate>
in viewDidLoad method tell the gadgetBulletinsController that his delegate is the FirstViewController class, like this:
if (gadgetBulletinsContoller == nil) {
gadgetBulletinsContoller = [[GadgetBulletinsTVContoller alloc] init];
gadgetBulletinsContoller.delegate = self;
}
and implement the GadgetBulletinsTVControllerDelegate's methods:
- (void)showItemDetails:(id)selectedItem
{
if([delegate respondsToSelector:#selector(showDetailsScreenForItem:)])
{
[delegate showDetailsScreenForItem:selectedItem];
}
}
In FirstViewController.h declare a protocol like below:
#protocol FirstViewControllerDelegate <NSObject>
- (void)showDetailsScreenForItem:(id)item;
#end
and declare a delegate property like below(don't forget to synthesize in .m file):
#property (nonatomic, assign)IBOutlet id<FirstViewControllerDelegate>delegate;
In MultipleViewController.xib select the FirstViewController screen and in outlets drag from the delegate to the fileOwner for setting the value of the delegate to the MultipleViewController(you can do this in code if you want to).
In MultipleViewController.m tell the MultipleViewController to implement the FirstViewControllerDelegate protocol like below:
#interface MultipleViewController ()<FirstViewControllerDelegate>
and implement the protocol method:
- (void)showDetailsScreenForItem:(id)item
{
DetailViewController *detailController = [[DetailViewController alloc] initWithNibName:#"DetailView" bundle:nil];
[detailController changeSubjectText:item];
[self.navigationController pushViewController:detailController animated:YES];
}
In DetailViewController modify the closeDetail method to look like this:
- (IBAction)closeDetail:(id)sender {
NSLog(#"closeDetail");
[self.navigationController popViewControllerAnimated:YES];
}
and voila, Your GadgetBulletinsTVController items details are pushed. You need to do the same steps for the other controllers from where you want to show details.
instead of removing the view from window just reload the basic view which contains all the table views using self.window.rootviewcontroller
EDIT
i got the solution by creating appDelegate what you have to do is just described below
First .h and .m file of AppDelegate Here (MultipleAppDelegate)
in .h add
#property (strong, nonatomic) id<UIApplicationDelegate>delegate;
in .m add
#synthesize delegate;
now where ever you like to add detailView just add below in .h and .m files as described
in .h file here(GadgetBulletinsTVContoller)
#import "MultipleAppDelegate.h"
and in interface one variable like this
MultipleAppDelegate *Mydelegate;
in .m file in viewDidLoad or loadView method
Mydelegate = [[UIApplication sharedApplication]delegate];
then at loading the detailView do this
navigationController = [[UINavigationController alloc] initWithRootViewController:detailController];
Mydelegate.window.rootViewController = navigationController;
[Mydelegate.window makeKeyAndVisible];
now at the detailViewController's .h and .m files
in .h file
#import "MultipleAppDelegate.h"
and in interface
MultipleAppDelegate *appDelegate;
in .m file in viewDidLoad or loadView method
appDelegate = [[UIApplication sharedApplication]delegate];
and on close button click
//Not required
//[self.navigationController popViewControllerAnimated:NO];
appDelegate.viewController = [[MultipleViewController alloc] initWithNibName:#"MultipleViewController" bundle:nil];
appDelegate.window.rootViewController = appDelegate.viewController;
[appDelegate.window makeKeyAndVisible];
That's all it will work fine only problem is that it take's 1 or 2 seconds to navigate and show the multipalViewController
enjoy Coding :)
Happy Coding :)
I just created an empty iOS project and added a UIViewController with a nib file. This should load my main view.
How do I tell my application to load a certain UIViewController as main view? Do I have to set it on the app delegate or somewhere in xcode?
In your app delegate have a variable for the controller....
MyViewController myController;
Then you want...
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
myController = [[MYViewController alloc] initWithNibName:#"MyViewController" bundle:nil];
[self.window addSubview:myController.view];
[self.window makeKeyAndVisible];
return YES;
}
You can also hook this up via Interface Builder, but the above is how you would do it in code.
