uiimageview

hey guys, this is my first time post here, and im pretty new to iphone programming. i just started about a month ago and have only been tinkering with small tutorial type applications but anyways, heres my question i currently have a UIScrollView thats scrollable and zoomable, that loads a UIImageView subview, and i want to add in some controls(UIButtons) over the image view but when i zoom in and out the whole group(the buttons and the image) zoom togeather. if i add the UIButtons to my UIScrollView and zoom, the image zooms and the buttons stay in origional place if i add the UIButtons to my

I'm working with filtering images that I'm taking with the camera. I pass the image I get from the camera through the below method. Which I have the returned UIImage sent to a UIImageView . For some reason when it passes through this method the image is getting rotated. What am I doing wrong? - (UIImage *) applyFilterToImage:(UIImage *)image withFilter:(NSString *)filterName { beginImage = [[[CIImage alloc] initWithImage:image] autorelease]; context = [CIContext contextWithOptions:nil]; filter = [CIFilter filterWithName:@"CISepiaTone" keysAndValues:kCIInputImageKey, beginImage, @

Trying to make UIImageView scale when the scrollview is bouncing down. The idea was stolen from this dribbble: https://dribbble.com/shots/3341878-Product-Page As you can see, image is like'a scaling when the scrollview is bouncing down. In my app I have the UIImageView inside the UIScrollview, I can't understand how to fix the top of the UIImageView while the UIScrolvview is bouncing down. Here is what I want to do: Apply a scale transform to your imageView based on your scrollview's offsets: extension ViewController: UIScrollViewDelegate { public func scrollViewDidScroll(_ scrollView:

I have a UIImageView on top of a UIScrollView, and I would like it to fit the device width, its height then being automatically set so that the image ratio is preserved. I am using Auto Layout, so I used constraints to bind the UIImageView to the top, left and right edges of the screen. My problem is, the UIImageView automatically resizes its frame to fit the UIImage height. And I cannot really change this frame afterwards, as it lets a gap between the UIImageView and the other UI elements, that are supposed to be just under it. I found a workaround by manually resizing the image to the good

I have a UIImageView that should animate from size (0,0) --> (93,75) I have the following [UIView animateWithDuration:0.5 delay:0 options:UIViewAnimationOptionTransitionNone animations:^{ imgButton.layer.anchorPoint = CGPointMake(imgButton.bounds.size.width/2, imgButton.bounds.size.height/2); CGRect btnFrame = imgButton.frame; btnFrame.size.width = 105; btnFrame.size.height = 85; imgButton.frame = btnFrame; } completion:^(BOOL finished) { [self animageButton2:imgButton]; }]; This is working but the only problem I have is that it is not animating from the center of the UIImageView but from the

I'm currently trying to create a subclass of UIImageView in order to make it download its image from server asynchronously ;) I tried to do it by myself but I haven't gone very far yet :D Anyway, I looked around here and found this : AsyncImageDownload I had a look at the code and the first which springs to mind is : why subclassing a UIView and not a UIImageView ?!? Any thoughts ? Cheers mates, Gotye. Nir Levy The reason it is subclassing UIView is so that you should, for example, display a UIActivityIndicator while the image is being downloaded. They do not show this in their example but I

In an iPhone word game I have an UIScrollView (holding UIImageView ) and 7 draggable custom UIView s placed initially at the bottom (and outside the scroll view): In the single ViewController.m I have overwritten viewDidLayoutSubviews so that it always sets the zoomScale of the scroll view - to have the UIImageView fill exactly 100% of the screen width. This works well - for portrait and landscape modes. And when the app is just started: My problem is however, when I first pinch/zoom/double-tap the scroll view and then move one of the seven Tile.m views: Suddenly (not every time)
