ios - SizeToFit on UIImageView not working
ios, sizetofit, uiimageview
Solution
Check the image size:
NSLog(@"%@", NSStringFromCGSize(imageView.image.size));
You may want to set `imageView` frame based on the image size manually, for example, if the image is too large to fit the `imageView`'s superview.
Problem
I have a UIImageView which loads in images from the documents directory on the ios file system . The problem is that when I call ``` [imageView sizeToFit]; ``` It does not work. I think it is because the image hasn't loaded fully at that point and so the sizeToFit part is called before it has the image width & height. Could someone point me in the direction of a fix please. Here is my code: ``` imageView.contentMode = UIViewContentModeScaleAspectFit; imageView.image = [UIImage imageWithContentsOfFile:[FileOperations getLibraryPath:[NSString stringWithFormat:@"%d.png", listData.imageId]]]; [imageView sizeToFit]; [imageScroll setContentOffset:CGPointMake(0, 0)]; imageScroll.contentSize = imageView.frame.size; imageScroll.decelerationRate = UIScrollViewDecelerationRateFast; imageScroll.minimumZoomScale = 1; imageScroll.maximumZoomScale = 2; [imageScroll setZoomScale:imageScroll.minimumZoomScale]; [imageScroll addSubview:imageView]; ``` Thanks, Ashley
