HI, I develop an application in which i want to implement the splash screen, on that splash screen i want to bind the scrollView and UIImage. My code as follow,
-(void)splashAnimation{
window = [[UIWindow alloc] initWithFrame:CGRectMake(0, 0, 320, 420)];
//scrollView = [[UIScrollView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]];
scrollView = [[UIScrollView alloc] initWithFrame:[window bounds]];
scrollView.pagingEnabled = NO;
scrollView.bounces = NO;
UIImage *image = [UIImage imageNamed:@"splash.png"];
UIImageView *imageView = [[UIImageView alloc] initWithImage:image];
imageView.userInteractionEnabled = NO;
[scrollView addSubview:imageView];
[scrollView setDelegate:self];
//[scrollView release];
}
- (void)applicationDidFinishLaunching:(UIApplication *)application {
[self splashAnimation];
[self initControllers];
[window addSubview:[mainTabBarController view]];
[window makeKeyAndVisible];
}
On my given code the one blank window comes up and stay on. I want to on that blank screen bind my splash.png.
*The Above problem is solved* My current code is
scrollView.pagingEnabled = NO; scrollView.bounces = NO;
UIImage *image = [UIImage imageNamed:@"splash.png"];
UIImageView *imageView = [[UIImageView alloc] initWithImage:image];
imageView.userInteractionEnabled = NO;
[scrollView addSubview:imageView];
scrollView.maximumZoomScale = 4.0f;
scrollView.minimumZoomScale = 1.0f;
CGRect rect = CGRectMake(119, 42, 208, 166);
[scrollView zoomToRect:rect animated:YES];
[scrollView setDelegate:self];
[window addSubview:scrollView];
[window makeKeyAndVisible];
i want to zoom the particular part of scrollView.
