UIViewContentModeScaleAspectFit in UIImageView does not work correctly - ios

Question

I try to fit an Image into my UIImageView which is called imgBack
I define my UIImageView in the header as IBOutlet
IBOutlet UIImageView *imgBack;
in my viewDidLoad function I set the contentMode like this:
imgBack.contentMode = UIViewContentModeScaleAspectFit;
But after I load an image into imgBack like this:
imgBack.image = [UIImage imageWithContentsOfFile: imagePath];
it does not scale to fit into the imageview
This is the picture I load into imgBack:
image i try to load
And this is how it looks like in the view: image in UIImageView
As you see, the image does not fit into the View.
Does anyone know why?

Answer 1

If changing ImageView contentMode does not work for you, then you can try to resize the image to fit in Image View with help of following code
UIImage *originalImage = [UIImage imageWithContentsOfFile: imagePath];
imgBack.image = [self resizeImage: originalImage imageSize: imgBack.size];
and add this code to your ViewController
-(UIImage*)resizeImage:(UIImage *)image imageSize:(CGSize)size
{
UIGraphicsBeginImageContext(size);
[image drawInRect:CGRectMake(0,0,size.width,size.height)];
UIImage* newImage = UIGraphicsGetImageFromCurrentImageContext();
//here is the scaled image which has been changed to the size specified
UIGraphicsEndImageContext();
return newImage;
}

Attach the image to UIImageView first and then change the content mode
imgBack.image = [UIImage imageWithContentsOfFile: imagePath];
imgBack.contentMode = UIViewContentModeScaleAspectFill;
imgBack.clipsToBounds = YES;

Answer 3

below are the mode try and check
UIViewContentModeScaleToFill,
UIViewContentModeScaleAspectFit, // contents scaled to fit with fixed aspect. remainder is transparent
UIViewContentModeScaleAspectFill, // contents scaled to fill with fixed aspect. some portion of content may be clipped.
UIViewContentModeRedraw, // redraw on bounds change (calls -setNeedsDisplay)
UIViewContentModeCenter, // contents remain same size. positioned adjusted.
UIViewContentModeTop,
UIViewContentModeBottom,
UIViewContentModeLeft,
UIViewContentModeRight,
UIViewContentModeTopLeft,
UIViewContentModeTopRight,
UIViewContentModeBottomLeft,
UIViewContentModeBottomRight,
