Splash screen related in iphone - iphone

Question

Hi I am trying to splash screen with the help of timer. but it can't. IS any suggestion regarding this code.........
SplashViewController.h:-
#import <UIKit/UIKit.h>
#import "MainMenu.h"
#interface SplashViewController : UIViewController {
UIImage *imgSplash;
NSTimer *timer;
MainMenu *objMainMenuView;
}
#property (nonatomic,retain) NSTimer *timer;
#property (nonatomic,retain) UIImage *imgSplash;
#property (nonatomic,retain) MainMenu *objMainMenuView;
#end
SplashViewController.m:-
#import "SplashViewController.h"
#implementation SplashViewController
#synthesize timer,imgSplash,objMainMenuView;
// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.
- (void)viewDidLoad {
[super viewDidLoad];
timer = [[NSTimer alloc] init];
UIImageView *splashImageView = [[UIImageView alloc] initWithFrame:CGRectMake(0,0,320,460)];
imgSplash = [[UIImage alloc] init];
imgSplash = [UIImage imageNamed:#"chicocredit_splash.png"];
[splashImageView setImage:imgSplash];
[self.view addSubview:splashImageView];
timer = [NSTimer timerWithTimeInterval:2.0 target:self.timer selector:#selector(fadeScreen) userInfo:nil repeats:NO];
if([timer isValid]==1)
{
[timer fire];
//self.view.alpha = 0.0;
objMainMenuView = [[MainMenu alloc] initWithNibName:#"MainMenu" bundle:nil];
[self.navigationController pushViewController:objMainMenuView animated:YES];
}
}
-(void) onTimer{
NSLog(#"LOAD");
}
- (void)fadeScreen
{
[UIImageView beginAnimations:nil context:nil];
[UIImageView setAnimationDuration:2.0];
[UIImageView setAnimationDelegate:self];
[UIImageView commitAnimations];
//[UIView setAnimationDidStopSelector:#selector(finishedFading)];
//self.view.alpha = 0.0;
//[UIView commitAnimations];
}
/*
- (void) finishedFading
{
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:5.0];
//self.view.alpha = 1.0;
//viewController.view.alpha = 1.0;
//self.objMainMenuView.view.alpha = 1.0;
[UIView commitAnimations];
//[splashImageView removeFromSuperview];
}*/
- (void)dealloc {
[super dealloc];
}
#end

Answer 1

Use this It may be solution for that.
- (void)viewDidLoad {
timer = [[NSTimer alloc] init];
CGRect myImageRect = CGRectMake(0.0f, 0.0f, 320.0f, 460.0f);
splashImageView = [[UIImageView alloc] initWithFrame:myImageRect];
[splashImageView setImage:[UIImage imageNamed:#"image3.jpg"]];
splashImageView.opaque = YES;
[self.view addSubview:splashImageView];
[splashImageView release];
[self performSelector:#selector(doTHis) withObject:nil afterDelay:2.0];
[super viewDidLoad];
}
-(void)doTHis{
objMainMenuView = [[MainMenu alloc] initWithNibName:#"MainMenu" bundle:nil];
[self.navigationController pushViewController:objMainMenuView animated:YES];
}
Good Luck

Looks like your MianMenu is getting pushed before you can see the fade effect. Its because you are firing the timer and pushing the Main Menu immediately.
// Schedule the timer here.
[NSTimer timerWithTimeInterval:2.0f target:self selector:#selector(timerFireMethod:) userInfo:nil repeats:NO];
// Timer fire method.
-(void) timerFireMethod:(NSTimer *) theTimer {
[UIView beginAnimations:nil context: nil];
[UIView setAnimationDuration:2.0f];
[UIView setAnimationDelegate:self];
[UIView setAnimationDidStopSelector: #selector(animationDidStop: finished: context:)];
// Put animation code.
[UIView commitAnimations];
}
// Called when animation finishes.
-(void) animationDidStop:(NSString *)animationID finished:(NSNumber *)finished context:(void *)context {
// Called when animation finishes.
// Push the Main menu here.
}
Keep break point in the timer fire method. It should get called after 2 seconds as specified.
Then keep break point in the animationDidStopSelector method. It will get called after your fade animation of 2 seconds.

Your code is leaked:
1:
timer = [[NSTimer alloc] init]; //Leak here, remove this line
.
.
.
timer = [NSTimer timerWithTimeInterval:2.0 target:self.timer selector:#selector(fadeScreen) userInfo:nil repeats:NO];
2:
imgSplash = [[UIImage alloc] init];//Leak here, remove this line
imgSplash = [UIImage imageNamed:#"chicocredit_splash.png"];
3:
UIImageView *splashImageView = [[UIImageView alloc] initWithFrame:CGRectMake(0,0,320,460)];
...
[splashImageView setImage:imgSplash]; //Leak here, should release splashImageView

Answer 4

Why not, do everything else after timer expired and fading is done.
- (void) finishedFading
{
objMainMenuView = [[MainMenu alloc] initWithNibName:#"MainMenu" bundle:nil];
[self.navigationController pushViewController:objMainMenuView animated:YES];
}

short cut: use another viewController with imageView present it modally and dismiss with animation dissolve.
You should present view in viewWillAppear.Start timer on viewLoad of second viewController.When timer fires dismiss it.
