Animate images in uiimageview

Solution 1
To download images from web service:
NSData *imageData = [NSData dataWithContentsOfURL:"*Url from web service*"];
UIImage *imageOne = [UIImage imageWithData:imageData];
likely download all images from web service and create an array like:
NSArray *imagesArray = [NSArray arrayWithObjects:imageOne...........,nil];
and use with little modification:
UIImageView* animatedImageView = [[UIImageView alloc] initWithFrame:self.view.bounds];
animatedImageView.animationImages = imagesArray;
animatedImageView.animationDuration = 1.0f;
animatedImageView.animationRepeatCount = 0;
[animatedImageView startAnimating];
[self.view addSubview: animatedImageView];

Got a Perfect code for animation can automatically change images in image view in swift4
class ViewController: UIViewController {
var imgarray = [UIImage(named:"f1.png")!,
UIImage(named:"f2.png")!,
UIImage(named:"f3.png")!,
UIImage(named:"f4.png")!,
UIImage(named:"f5.png")!,
UIImage(named:"index1.png")!,
UIImage(named:"index2.png")!,
UIImage(named:"index3.png")!]
@IBOutlet weak var imgview: UIImageView!
override func viewDidLoad() {
super.viewDidLoad()
self.imgview.animationImages = imgarray
self.imgview.animationDuration = 10.0
self.imgview.animationRepeatCount = 0
self.imgview.startAnimating()
}
}
Solution 3
Swift
Assuming that imageView is added via storyboard
Intialize array:
self.imageArray = [UIImage(named:"Download_060.png")!,UIImage(named:"Download_061.png")!,UIImage(named:"Download_062.png")!,
UIImage(named:"Download_063.png")!,UIImage(named:"Download_064.png")!,UIImage(named:"Download_065.png")!,
UIImage(named:"Download_066.png")!,UIImage(named:"Download_067.png")!]
Add Code to animate on button action or as per required
self.imgView.animationImages = self.imageArray
self.imgView.animationDuration = 1.0
self.imgView.animationRepeatCount = 0
self.imgView.startAnimating()
Stop Animation
self.imgView.animationRepeatCount = 1 // IF Require once set this 1, 0 == infinite
OR
self.imgView.stopAnimating()

Groot almost 11 yearsJust a side note: Make sure the downloading is not performed on the main thread.
-
Vinodh almost 11 yearsno issues. But time takes for download . you have to wait patiently till images get downloaded
-
user2515868 almost 11 yearsIs it possible to change the background image of the uibutton in similar way
-
Vinodh almost 11 yearsplease ask your question clearly , you want to change after a button click or directly
-
MoDJ over 9 yearsJust an FYI, but your code will crash the device if the images are too large using this approach. Holding all decoded image data is memory is not a good idea, do some more research to find out how to fix that.
