Everything works ok on simulator , but on the real iphone 3g there is bug.
I call Splash Screen twice. First time - ok , second time i see the bug : http://img413.imageshack.us/i/bugicu.png/
How can i fix it ?
#interface iStateGameAppDelegate : NSObject
{
UIWindow* window;
UINavigationController* navigationController;
}
-(void) showSpalshScreen;
-(void) showSwitchViewController;
#property (nonatomic, retain) IBOutlet UIWindow *window;
#property (nonatomic, retain) IBOutlet UINavigationController *navigationController;
#end
#implementation iStateGameAppDelegate
#synthesize window;
#synthesize navigationController;
- (BOOL) application:(UIApplication*) application didFinishLaunchingWithOptions:(NSDictionary*) launchOptions
{
[self showSpalshScreen];
[window makeKeyAndVisible];
return YES;
}
-(void) showSpalshScreen
{
SplashScreen* splashScreen = [[[SplashScreen alloc] initWithNibName:#"SplashScreen" bundle:[NSBundle mainBundle]] autorelease];
[window addSubview:[splashScreen view]];
}
-(void) showSwitchViewController
{
SplashScreen* splashScreen = [[[SplashScreen alloc] initWithNibName:#"SplashScreen" bundle:[NSBundle mainBundle]] autorelease];
[window addSubview:[splashScreen view]];
}
- (void) dealloc
{
[navigationController release];
[window release];
[super dealloc];
}
#interface SplashScreen : UIViewController {}
#end
#implementation SplashScreen
// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.
- (void)viewDidLoad
{
[super viewDidLoad];
NSTimer *timer = [[NSTimer timerWithTimeInterval:1.0 target:self selector:#selector(timerFired:) userInfo:nil repeats:NO] retain];
[[NSRunLoop currentRunLoop] addTimer:timer forMode:NSDefaultRunLoopMode];
}
-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation
{
return (toInterfaceOrientation == UIInterfaceOrientationLandscapeRight);
}
- (void)timerFired:(NSTimer *)timer
{
[[UIApplication sharedApplication] setStatusBarHidden:FALSE];
iStateGameAppDelegate* app = [UIApplication sharedApplication].delegate;
[app showSwitchViewController];
[[self view] removeFromSuperview];
[timer invalidate];
[timer release];
timer = nil;
}

Make sure the view's delegate is correctly set.
You should probably check for both UIInterfaceOrientationLandscapeRight and UIInterfaceOrientationLandscapeLeft.

I'm finding it difficult to get started in Objective-C.
I'm executing the following code when a button is clicked:
NSLog(#"hi");
MainMenuDriver *mainMenuDriver= [[MainMenuDriver alloc] initWithNibName:nil bundle:nil];
[[self navigationController]pushViewController:mainMenuDriver animated:YES];
I can see "hi" in the console when I hit the button, it's just that the view should change to MainMenuDriver. But nothing happens!
Please help!

I can see a couple of things:
Your nib file's name is different from the name of your class. If you put nil, the UIViewController will try to load a nib file with the UIViewController's name. Your UIViewController can be MainMenuDriver but your nib file name can be MainMenuDriverNibFileName.nib
[self navigationController] is nil.
For this, do the following:
NSLog(#"hi");
if([self navigationController]){
MainMenuDriver *mainMenuDriver= [[MainMenuDriver alloc] initWithNibName:nil bundle:nil];
[[self navigationController]pushViewController:mainMenuDriver animated:YES];
}
else{
NSLog(#"Houston we have a problem");
}
Update 1:
So, its nil, what you can do is the following:
Quick and Dirty:
[self presentViewController:mainMenuDriver animated:YES];
Instead of UIViewController switch to a UINavigationController.
I have a tab controller with 2 tabs "My information" and "their Information", which is just a bunch of text boxes. I want a Navigation controller at the top so I can go back, but the back button won't show up... here is my code:
Button pressed to show Form:
-(IBAction)onIncidentAidFormPressed:(id)sender {
FormController *aidForm = [[FormController alloc] initWithNibName:#"formController" bundle:nil];
aidForm.managedObjectContext = self.managedObjectContext;
[self.navigationController pushViewController:aidForm animated:YES];
}
In FormController.m - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil:
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
self.title = NSLocalizedString(#"Aid Form", #"Aid Form title");
}
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
UIViewController *viewController1 = [[MyInformationController alloc] initWithNibName:#"MyInformationController" bundle:nil];
UIViewController *viewController2 = [[TheirInformationController alloc] initWithNibName:#"TheirInformationController" bundle:nil];
UINavigationController *navController = [[UINavigationController alloc] initWithNibName:#"navController" bundle:nil];
[navController pushViewController:viewController1 animated:YES];
self.tabBarController = [[UITabBarController alloc] init];
self.tabBarController.viewControllers = [NSArray arrayWithObjects:navController, viewController2, nil];
self.window.rootViewController = self.tabBarController;
[self.window makeKeyAndVisible];
return self;
The tabs show up correctly, and the navigation bar is there but no back button is shown to get back.

So far I know this is a good way to add ur views to tabbar. So try this
UIViewController *viewController1 = [[MyInformationController alloc] initWithNibName:#"MyInformationController" bundle:nil];
UIViewController *viewController2 = [[TheirInformationController alloc] initWithNibName:#"TheirInformationController" bundle:nil];
UINavigationController *navController1 = [[UINavigationController alloc] initWithRootViewController:viewController1];
UINavigationController *navController2 = [[UINavigationController alloc] initWithRootViewController:viewController2];
self.tabBarController = [[UITabBarController alloc] init];
self.tabBarController.viewControllers = [NSArray arrayWithObjects:navController1, navController2, nil];
To add back bar item , below ine is also used.
self.navigationItem.leftBarButtonItem = self.navigationItem.backBarButtonItem;
Please modify your method like this
-(IBAction)onIncidentAidFormPressed:(id)sender
{
FormController *aidForm = [[FormController alloc] initWithNibName:#"formController" bundle:nil];
aidForm.managedObjectContext = self.managedObjectContext;
self.navigationItem.backBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:#"Back" style:UIBarButtonItemStylePlain target:self action:nil];
[self.navigationController pushViewController:aidForm animated:YES];
}
you should replace your code with the following:
UIViewController *viewController1 = [[MyInformationController alloc] initWithNibName:#"MyInformationController" bundle:nil];
UIViewController *viewController2 = [[TheirInformationController alloc] initWithNibName:#"TheirInformationController" bundle:nil];
UINavigationController *navController1 = [[[UINavigationController alloc] initWithRootViewController:viewController1] autorelease];
UINavigationController *navController2 = [[[UINavigationController alloc] initWithRootViewController:viewController2] autorelease];
self.tabBarController = [[UITabBarController alloc] init];
self.tabBarController.viewControllers = [NSArray arrayWithObjects:navController1, navController2, nil];
let me know any thing else you need........
I having a problem with a Bad Exception that I could not locate at first, but now have it pinned down on a [super dealloc];, but I have no idea why this happens.
Here is my code :
EditingViewController.h
#interface EditingViewController : UIViewController
{
NSManagedObject *editedObject;
NSString *editedFieldKey;
NSString *editedFieldName;
}
#property (nonatomic, retain) NSManagedObject *editedObject;
#property (nonatomic, retain) NSString *editedFieldKey;
#property (nonatomic, retain) NSString *editedFieldName;
- (IBAction)cancel;
- (IBAction)save;
#end
EditingViewController.m
#import "EditingViewController.h"
#implementation EditingViewController
#synthesize editedObject, editedFieldKey, editedFieldName;
#pragma mark -
#pragma mark View lifecycle
- (void)viewDidLoad
{
self.title = NSLocalizedString(editedFieldName, nil);
// Configure the save and cancel buttons.
UIBarButtonItem *saveButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemSave target:self action:#selector(save)];
self.navigationItem.rightBarButtonItem = saveButton;
[saveButton release];
UIBarButtonItem *cancelButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemCancel target:self action:#selector(cancel)];
self.navigationItem.leftBarButtonItem = cancelButton;
[cancelButton release];
}
- (void)viewWillAppear:(BOOL)animated
{
[super viewWillAppear:animated];
}
- (IBAction)save
{
[self.navigationController popViewControllerAnimated:YES];
}
- (IBAction)cancel
{
// Don't pass current value to the edited object, just pop.
[self.navigationController popViewControllerAnimated:YES];
}
- (void)dealloc
{
[editedObject release];
[editedFieldKey release];
[editedFieldName release];
//[super dealloc];
}
#end
As you can see, I commented the [super dealloc];, which is causing the Bad Exception, but this is obviously not a good solution.
Any idea what I am doing wrong ?
Thanks
The properties might have never been used, so they haven't been initialized in any way
- (void)dealloc
{
self.editedObject = nil;
self.editedFieldKey = nil;
self.editedFieldName = nil;
[super dealloc];
}
I am using code from Ed Marty's answer for the question here but am having real trouble with a few bits.
On the click of a button I have got the datepicker appearing, but the 'done' button however isn't. I am also getting an error from the line:

On this line:
[delegate datePickerController:controller didPickDate:datePicker.date];
try replacing controller with self.
I'm not sure if I wrote this code well (get clicks on touching buttons rapidly):
#import "iEngineRoomAppDelegate.h"
#import "iEngineRoomViewController.h"
#import "SoundEffect.h"
#implementation iEngineRoomAppDelegate
#synthesize window;
#synthesize viewController;
- (void)applicationDidFinishLaunching:(UIApplication *)application {
// Override point for customization after app launch
[window addSubview:viewController.view];
[window makeKeyAndVisible];
[self setupSounds];
}
- (void)setupSounds {
NSBundle *mainBundle = [NSBundle mainBundle];
timbal_big_Sound = [[SoundEffect alloc] initWithContentsOfFile:[mainBundle pathForResource:#"timbal_big" ofType:#"caf"]];
timbal_sm_Sound = [[SoundEffect alloc] initWithContentsOfFile:[mainBundle pathForResource:#"timbal_sm" ofType:#"caf"]];
}
- (IBAction)timbal_big: (id)sender {
SoundEffect *currentSoundEffect= timbal_big_Sound;
[currentSoundEffect play];
}
- (IBAction)timbal_sm: (id)sender {
SoundEffect *currentSoundEffect= timbal_sm_Sound;
[currentSoundEffect play];
}
- (void)dealloc {
[timbal_big_Sound release];
[timbal_sm_Sound release];
[viewController release];
[window release];
[super dealloc];
}
#end
Memory management of the SoundEffect objects is right, if you meant that.
