我需要为iPhone应用程序实现动画闪屏。我见过skype应用程序已经实现了同样的东西。
任何人都知道如何在我的应用程序中实现相同的东西

您可以使用图像序列，这里是代码：
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;
并且只调用UIImageView的startAnimation和endAnimation方法。
OR
它非常简单......我用它来启动我的应用程序使用splashView.Hope它会帮助你....在AppDelegate.m中：
应用程序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];
删除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];
}

我们可以在webView中展示 .gif 图片，看起来很完美！
使用UIViewController取一个名为SplashView的新XIB班，然后添加一个UIWebView，其中包含（320.0,480.0）帧，隐藏statusbar。< / p>
在SplashView.h
#import <UIKit/UIKit.h>
@interface SplashView : UIViewController
@property(nonatomic, retain)IBOutlet UIWebView *webView;
@end
在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];
}
这大约是SplashView级。现在来到appdelegate的课堂。
- (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];
}

采取UIView＆amp;一个Imageview到它。将所有图像提供给ImageView以进行动画处理。
-(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];
}
这将显示您的应用程序图标。
之后，您将显示默认隐藏的控件，并从下到上为它们设置动画。
-(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];
}
希望这有帮助...

试试这个
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];
}

你需要使用一个viewcontroller启动你的应用程序，其中包含一个uiimageview。创建一系列.png图像，使其受到UIImageView check how to animate array of images in uiimageview的约束。进一步解雇它一旦你的动画需要实现一个协议，将通知你的应用程序的第一个viewcontroller开始解除动画

是的，简单的AppDelegate类首先污染了像bellow的imageview ..
@interface AppDelegate : UIResponder
{
UIImageView *splashView;
}
和.m文件......
- (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"];
}
我希望这可以帮到你..
