UIImage to slide downwards using animation - iphone

Question

How can implement image sliding down animation in ios app?
I've used this code:
imageview.animationImages = [NSArray arrayWithObjects:
[UIImage imageNamed:#"img10.png"],
[UIImage imageNamed:#"img11.png"],[UIImage imageNamed:#"img12.png"],[UIImage imageNamed:#"img13.png"],nil];
imageview.animationDuration = 10.00;
imageview.animationRepeatCount = 0;
[imageview startAnimating];
But this is only a simple slide show.
Help me.

Answer 1

try with this code..
imageview = [[UIImageView alloc] initWithFrame:self.view.frame];
imageview.animationImages = [NSArray arrayWithObjects:
[UIImage imageNamed:#"img10.png"],
[UIImage imageNamed:#"img11.png"],[UIImage imageNamed:#"img12.png"],[UIImage imageNamed:#"img13.png"],nil];
imageview.animationDuration = 1.25;
imageview.animationRepeatCount = 10;
[imageview startAnimating];
[self.view addSubview:animationView];
[imageview release];

Please try following code
-(void) createNewImage {
imageView = [[UIImageView alloc] initWithFrame:CGRectMake(0,0,320,460)];
imageView.animationImages = [NSArray arrayWithObjects:
[UIImage imageNamed:#"img10.png"],
[UIImage imageNamed:#"img11.png"],
[UIImage imageNamed:#"img12.png"],
[UIImage imageNamed:#"img13.png"],nil];
[imageView setAnimationRepeatCount:10];
imageView.animationDuration =1.5;
[imageView startAnimating];
[NSTimer scheduledTimerWithTimeInterval:15.0 target:self selector:#selector(setLastImage:) userInfo:nil repeats:NO];
}
-(void)setLastImage:(id)obj
{
[imageView performSelectorOnMainThread:#selector(setImage:) withObject:[UIImage imageNamed:#"img12.png"] waitUntilDone:YES];
}

You can change the centre of UIImageView using imgVw.centre, you can update the centre with NSTimer. Vary the centre according to the screen, you can get screen height from
[[UIScreen mainScreen]bounds].size.height
theTimer = [NSTimer scheduledTimerWithTimeInterval:1.0f
target:self
selector:#selector(updateTimer:)
userInfo:nil
repeats:YES];
- (void)updateTimer:(NSTimer *)theTimer {
//update centre;
imgVw.centre.y += 4;
// you can update the image also if needed use if case
imgVw.image = image2;
}
