Answer 1

[_imageView setImage:[ViewController imageWithContentMode:[UIImage imageNamed:@"howwehelp_bg.png"] withScaledSize:_imageView.bounds.size]];

_imageView.contentMode = UIViewContentModeScaleToFill;

+(UIImage *)imageWithContentMode:(UIImage *)image withScaledSize:(CGSize)newSize{

UIGraphicsBeginImageContextWithOptions(newSize, NO, 0.0);

[image drawInRect:CGRectMake(0, 0, newSize.width, newSize.height)];

UIImage *imageNew = UIGraphicsGetImageFromCurrentImageContext();

UIGraphicsEndImageContext();

return imageNew;

}

Answer 2

You can apply this code for fit images.

+(UIImage*)imageWithImage: (UIImage*) sourceImage scaledToWidth: (float) i_width
{
float oldWidth = sourceImage.size.width;
float scaleFactor = i_width / oldWidth;

float newHeight = sourceImage.size.height * scaleFactor;
float newWidth = oldWidth * scaleFactor;

UIGraphicsBeginImageContext(CGSizeMake(newWidth, newHeight));
[sourceImage drawInRect:CGRectMake(0, 0, newWidth, newHeight)];
UIImage *newImage = UIGraphicsGetImageFromCurrentImageContext();    
UIGraphicsEndImageContext();
return newImage;

}
