I want to load a view of my choice after the default splash view of iphone launches. Does someone know how to achieve this ? i am new to xcode and ios development.
Add [self setUpSplash]; method in - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions method. And add following Three method in AppDelegate.m
-(void) setUpSplash {
self.splashImgView = [[UIImageView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]];
[self.splashImgView setImage: [UIImage imageNamed:#"splash.png"]];
[self.window addSubview: self.splashImgView];
[NSTimer scheduledTimerWithTimeInterval:2.0f target:self selector:#selector(closeSplashWithTimer:) userInfo:nil repeats:NO];
}
- (void)closeSplashWithTimer:(NSTimer *)theTimer
{
[UIView beginAnimations:#"ToggleViews" context:nil];
[UIView setAnimationDuration:1.0];
// Make the animatable changes.
splashImgView.alpha = 0.0;
self.mvNavigationController.view.alpha = 1.0;
// Commit the changes and perform the animation.
[UIView commitAnimations];
[NSTimer scheduledTimerWithTimeInterval:2.0f target:self selector:#selector(closeSplashWithTimerAgain:) userInfo:nil repeats:NO];
}
- (void)closeSplashWithTimerAgain:(NSTimer *)theTimer
{
[self.splashImgView removeFromSuperview];
}

I need to implement animated splash screen to the iPhone application. I have seen skype application where same thing is already implemented.
Can anyone has idea how can i implement same thing in my applicatio
You can use sequence of images, here is code :
for(NSInteger i=1;i<=totalImages;i++){
NSString *strImage = [NSString stringWithFormat:#"Activity_%d",i];
UIImage *image = [UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:strImage ofType:#"png"]];
[imageArray addObject:image];
}
splashImageView.animationImages = imageArray;
splashImageView.animationDuration = 0.8;
and just call startAnimation and endAnimation method of UIImageView.
OR
Its very simple...I had used it in to begin my app with splashView.Hope it vil help you.... In AppDelegate.m:
application didFinishLaunchingWithOptions:
UIImage* image=[UIImage imageNamed:#"splash.jpg"];
splashView=[[UIImageView alloc]initWithImage:image];
[window addSubview:splashView];
[window bringSubviewToFront:splashView];
[self performSelector:#selector(removeSplash) withObject:self afterDelay:2];
[window makeKeyAndVisible];
To remove splashView:
-(void)removeSplash{
[UIView beginAnimations:nil context:nil];
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:window cache:YES];
[UIView setAnimationDuration:0.75];
[UIView setAnimationDelegate:self];
[splashView removeFromSuperview];
[UIView commitAnimations];
[window addSubview:viewController.view];
}
We can show a .gif image in webView and it looks perfect!
Take a new UIViewController class named SplashView with XIB and then add an UIWebView with (320.0, 480.0) frame, hidden statusbar also.
In SplashView.h
#import <UIKit/UIKit.h>
#interface SplashView : UIViewController
#property(nonatomic, retain)IBOutlet UIWebView *webView;
#end
In SplashView.m
- (void)viewDidLoad
{
[super viewDidLoad];
NSString *imagePath = [[NSBundle mainBundle] pathForResource: #"animated" ofType: #"gif"];
NSData *data = [NSData dataWithContentsOfFile:imagePath];
[self.webView setUserInteractionEnabled:NO];
[self.webView loadData:data MIMEType:#"image/gif" textEncodingName:nil baseURL:nil];
}
This is about SplashView class. Now come to your appdelegate's class.
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// Override point for customization after application launch.
self.viewController = [[ViewController alloc] initWithNibName:#"ViewController" bundle:nil];
[[UIApplication sharedApplication] setStatusBarHidden:YES];
splashView = [[SplashView alloc]initWithNibName:#"SplashView" bundle:nil];
[self.window addSubview:splashView.view];
[self performSelector:#selector(changeView) withObject:nil afterDelay:3.0];
[self.window makeKeyAndVisible];
return YES;
}
-(void)changeView
{
[[UIApplication sharedApplication] setStatusBarHidden:NO];
[splashView.view removeFromSuperview];
[self.window setRootViewController:self.viewController];
}
Take a UIView & an Imageview into it. Give all your images to ImageView to animate.
-(void)viewDidLoad
{
NSArray *arrImage=[NSArray arrayWithObjects:
[UIImage imageNamed:#"1.png"],
[UIImage imageNamed:#"2.png"],
[UIImage imageNamed:#"3.png"],
nil];
imgVw.backgroundColor=[UIColor purpleColor];
imgVw.animationImages=arrImage;
imgVw.animationDuration=2.5;
imgVw.animationRepeatCount=1;
[imgVw startAnimating];
[NSTimer scheduledTimerWithTimeInterval:4.0 target:self selector:#selector(animateNext) userInfo:nil repeats:NO];
}
This will show up you application icon.
After that you will show the controls those would be hidden by default and animate them from bottom to up.
-(void)animateNext
{
lbl.hidden = NO;
btn.hidden = NO;
txt1.hidden = NO;
txt2.hidden = NO;
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:1.9];
lbl.frame=CGRectMake(lbl.frame.origin.x,lbl.frame.origin.y - 150,lbl.frame.size.width,lbl.frame.size.height);
imgVw.frame = CGRectMake(imgVw.frame.origin.x, imgVw.frame.origin.y - 150, imgVw.frame.size.width, imgVw.frame.size.height);
txt1.frame = CGRectMake(txt1.frame.origin.x, txt1.frame.origin.y - 150, txt1.frame.size.width, txt1.frame.size.height);
txt2.frame = CGRectMake(txt2.frame.origin.x, txt2.frame.origin.y - 150, txt2.frame.size.width, txt2.frame.size.height);
btn.frame = CGRectMake(btn.frame.origin.x, btn.frame.origin.y - 150, btn.frame.size.width, btn.frame.size.height);
[UIView commitAnimations];
}
Hope this help...
Try this
Appdelegate.h
#interface AppDelegate : UIResponder <UIApplicationDelegate>
{
UIImageView *splashView;
}
#property (strong, nonatomic) UIWindow *window;
#property (strong, nonatomic) ViewController *viewController;
- (void)startupAnimationDone:(NSString *)animationID finished:(NSNumber *)finished context:(void *)context;
AppDelegate.m
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// Override point for customization after application launch.
self.viewController = [[ViewController alloc] initWithNibName:#"ViewController" bundle:nil];
self.window.rootViewController = self.viewController;
[self.window makeKeyAndVisible];
// Make this interesting.
splashView = [[UIImageView alloc] initWithFrame:CGRectMake(0,0, 320, 480)];
splashView.image = [UIImage imageNamed:#"Default.png"];
[self.window addSubview:splashView];
[self.window bringSubviewToFront:splashView];
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:2.0];
[UIView setAnimationTransition:UIViewAnimationTransitionNone forView:self.window cache:YES];
[UIView setAnimationDelegate:self];
[UIView setAnimationDidStopSelector:#selector(startupAnimationDone:finished:context:)];
splashView.alpha = 0.0;
splashView.frame = CGRectMake(-60, -85, 440, 635);
[UIView commitAnimations];
return YES;
}
- (void)startupAnimationDone:(NSString *)animationID finished:(NSNumber *)finished context:(void *)context {
[splashView removeFromSuperview];
}
you need to start your app with a viewcontroller,with an uiimageview in it..Create a series of .png images to be subjected to the UIImageView check how to animate array of images in uiimageview. Further to dismiss it once animation over you would need to implement a protocol that will inform your starting first viewcontroller of your app to dismiss the animation
- (void) welcomeScreen
{
//Welcome Screen
UIImageView* welcome = [[[UIImageView alloc] initWithFrame:CGRectMake(0,0,320,480)]autorelease];
welcome.image = [UIImage imageNamed:#"img.png"];
[window addSubview:welcome];
[window bringSubviewToFront:welcome];
//Animation Effects (zoom and fade)
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:2.0];
[UIView setAnimationTransition:UIViewAnimationTransitionNone forView:window cache:YES];
[UIView setAnimationDelegate:welcome];
[UIView setAnimationDidStopSelector:#selector(removeFromSuperview)];
//set transparency to 0.0
welcome.alpha = 0.0;
//zoom effect
welcome.frame = CGRectMake(-60, -60, 440, 600);
[UIView commitAnimations];
}
yes simple in AppDelegate class first defile imageview like bellow..
#interface AppDelegate : UIResponder
{
UIImageView *splashView;
}
and in .m file...
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone)
{
splashView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 320, 480)];
splashView.image = [UIImage imageNamed:#"Default"];
[self.window addSubview:splashView];
[self performSelector:#selector(loadViewIphone) withObject:nil afterDelay:2.0];
}
[self.window makeKeyAndVisible];
return YES;
}
-(void)loadViewIphone
{
[splashView removeFromSuperview];
self.window.rootViewController = self.tabBarController;
[self.window makeKeyAndVisible];
CATransition *animation = [CATransition animation];
[animation setDelegate:self];
[animation setType:kCATransitionFade];
[animation setDuration:0.5];
[animation setTimingFunction:[CAMediaTimingFunction functionWithName:
kCAMediaTimingFunctionEaseInEaseOut]];
[[self.window layer] addAnimation:animation forKey:#"transitionViewAnimation"];
}
i hope this help you..
:)
I m struggling with this issue for so long but not able to find any solution for this
The issue i have is when i pause the audioplayer i want views to be paused from updating so i used timer invalidate to pause the views from loading but when i resume play only Audioplayer is resumed not the views cause i invalidated the timer.
Now i how i can resume updating views from that point where view was paused. By starting the timer again i can start updating views again but how program will know that at what view it was paused and it should resume updating views from that point. There are multiple views involved displayed code for only two.
-(void)playpauseAction:(id)sender
{
if
([audioPlayer isPlaying]){
[sender setImage:[UIImage imageNamed:#"play.png"] forState:UIControlStateSelected];
[audioPlayer pause];
[timer invalidate];
} else {
[sender setImage:[UIImage imageNamed:#"pause.png"] forState:UIControlStateNormal];
[audioPlayer play];
self.timer = [NSTimer scheduledTimerWithTimeInterval:11 target:self selector:#selector(displayviewsAction:) userInfo:nil repeats:NO];
}
}
- (void)displayviewsAction:(id)sender
FirstViewController *viewController = [[FirstViewController alloc] init];
viewController.view.frame = CGRectMake(0, 0, 320, 480);
[self.view addSubview:viewController.view];
[self.view addSubview:toolbar];
[viewController release];
self.timer = [NSTimer scheduledTimerWithTimeInterval:23 target:self selector:#selector(secondViewController) userInfo:nil repeats:NO];
-(void)secondViewController {
SecondViewController *secondController = [[SecondViewController alloc] init];
secondController.view.frame = CGRectMake(0, 0, 320, 480);
[self.view addSubview:secondController.view];
[self.view addSubview:toolbar];
[secondController release];
self.timer = [NSTimer scheduledTimerWithTimeInterval:27 target:self selector:#selector(ThirdviewController) userInfo:nil repeats:NO];
}
Thanks and appreciate for your answers and helping me out with this issue.
Use a background thread to basically bind the view to the player, something like this:
UIImageView* imageView; //the view that gets updated
int current_selected_image_index = 0;
float time_for_next_image = 0.0;
AVAudioPlayer* audioPlayer;
NSArray* image_times; //an array of float values representing each
//time when the view should update
NSArray* image_names; //an array of the image file names
-(void)update_view
{
UIImage* next_image_to_play = [image_names objectAtIndex:current_selected_image_index];
imageView.image = next_image_to_play;
}
-(void)bind_view_to_audioplayer
{
while(audioPlayer.isPlaying)
{
float currentPlayingTime = (float)audioPlayer.currentTime;
if(currentPlayingTime >= time_for_next_image)
{
current_selected_image_index++;
[self performSelectorOnMainThread:#selector(update_view) withObject:nil waitUntilDone:NO];
time_for_next_image = [image_times objectAtIndex:[current_selected_image_index+1)];
}
[NSThread sleep:0.2];
}
}
-(void)init_audio
{
current_selected_image_index = 0;
time_for_next_image = [image_times objectAtIndex:1];
}
-(void)play_audio
{
[audioPlayer play];
[self performSelectorInBackground:#selector(bind_view_to_audioplayer) withObject:nil];
}
-(void)pause_audio
{
[audioPlayer pause];
//that's all, the background thread exits because audioPlayer.isPlaying == NO
//the value of current_selected_image_index stays where it is, so [self play_audio] picks up
//where it left off.
}
also, add self as observer for the audioPlayerDidFinishPlaying:successfully: notification to reset when the audioplayer finishes playing.
I want to repeat an image again and again.But when i run my code it crashes with a warning "MainViewController may not respond to setneedsDisplay" and also"uiviewController may not respond to initwithFrame". Here is my code.
#import "MainViewController.h"
#implementation MainViewController
#synthesize car,road;
UIImage *currentImage;
int tileOffset=0;
-(void)awakeFromNib{
[[UIApplication sharedApplication]setStatusBarHidden:YES withAnimation:NO];
[car setAlpha:0];
[road setAlpha:0];
currentImage=[UIImage imageNamed:#"Road3.png"];
[NSTimer scheduledTimerWithTimeInterval:(.1) target:self selector:#selector(onTimer)
userInfo:nil repeats:YES];
[NSTimer scheduledTimerWithTimeInterval:(.01) target:self selector:#selector(onTimerRoad) userInfo:nil repeats:YES];
}
-(void)onTimerRoad{
tileOffset+=1;
[self setNeedsDisplay]; //here Get the warning
}
-(void)onTimer{
[self update1];
}
-(void)update1{
[self updateRoad];
}
-(void)updateRoad{
[self randomRoadUpdate];
}
-(void)randomRoadUpdate{
CGPoint oldPosition=road.center;
road.center=CGPointMake(oldPosition.x, oldPosition.y+1);
}
-(id)initWithFrame:(CGRect)frame{
if(self=[super initWithFrame:frame]){//here get warning
}
return self;
}
-(void)drawRect:(CGRect)rect{
CGImageRef image=CGImageRetain(currentImage.CGImage);
CGRect imageRect;
imageRect.origin=CGPointMake(160, 240);
imageRect.size=CGSizeMake(320, 480);
CGContextRef uicontext=UIGraphicsGetCurrentContext();
CGContextClipToRect(uicontext, CGRectMake(0, 0, rect.size.width, rect.size.height));
CGContextDrawTiledImage(uicontext, imageRect, image);
}
Thanks in advance..
setNeedDisplays is a method for UIView.... So you need to call [self.view setNeedDisplay] the second warning is about your assignment statement, try this to get it out:
self = [super initWithFrame:frame];
if(self){
//...
}
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
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
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.
What I want to do is that every ten second a ball is created outside of the screen, and when it is created it move to the center of the screen. How can I do this?
In your view controller set up a UIImageView property for your ball, contruct the ball and make sure its starting location is off the viewable area of the creen and then use an NSTimer which fires every ten seconds which callas a method that animates your ball across the screen to the centre.
-(void)viewDidLoad{
NSTimer *ballTimer = [NSTimer timerWithTimeInterval:10.0
target:self
selector:#selector(moveBall)
userInfo:nil
repeats:YES];
[[NSRunLoop mainRunLoop] addTimer:ballTimer forMode:NSRunLoopCommonModes];
myBall = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"MyBallImageFile.png"]];
myBall.center = CGPointMake(320/2, [self randNumBetween:-50:-100]);
[self.view addSubview:myBall];
}
-(void)moveBall{
myBall.center = CGPointMake(320/2, [self randNumBetween:-50:-100]);
[UIView animateWithDuration:5.0 animations:^{
myBall.center = CGPointMake(320/2, 480/2);
}];
}
----------EDIT------------
- (CGFloat)randNumBetween:(CGFloat) min :(CGFloat) max{
CGFloat difference = max - min;
return (((CGFloat) rand()/(CGFloat)RAND_MAX) * difference) + min;
}
- (void)viewDidLoad {
[super viewDidLoad];
myBallImage = [[UIImage imageNamed:#"ball.png"] retain];
myTimer = [NSTimer scheduledTimerWithTimeInterval:10.0 target:self selector:#selector(addBallToScreen) userInfo:nil repeats:YES];
}
- (void)viewDidUnload {
[myBallImage release];
[myTimer invalidate];
}
- (void)addBallToScreen {
//Create the imageView
UIImageView *imageView = [[UIImageView alloc] initWithImage:myBallImage];
imageView.transform = CGAffineTransformMakeTranslation(1000, 1000);
[self.view addSubview:imageView];
[imageView release];
//Animate the image view
[UIView beginAnimations:nil context:nil];
imageView.transform = CGAffineTransformMakeTranslation(50, 50);
[UIView commitAnimations];
}
