Portrait image is not properly resizing - ios

Question

landscape is properly resizing but Portrait image is not resizing properly.
Please somebody help me to sort out this problem.
code :-
CGSize newSize = CGSizeMake(width, height);
float widthRatio = newSize.width/image.size.width*image.scale;
float heightRatio = newSize.height/image.size.height*image.scale;
NSLog(#" image size %f %f %f",image.size.width,image.size.height,image.scale);
if(widthRatio > heightRatio)
newSize=CGSizeMake(image.size.width*heightRatio,image.size.height*heightRatio);
else
newSize=CGSizeMake(image.size.width*widthRatio,image.size.height*widthRatio);
UIGraphicsBeginImageContextWithOptions(newSize, NO, 0.0);
[image drawInRect:CGRectMake(0,0,newSize.width,newSize.height)];
UIImage* newImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();

Answer 1

Try this:
- (UIImage*)resizeImage:(UIImage *)image imageSize:(CGSize)size {
CGFloat imageWidth = image.size.width;
CGFloat imageHeight = image.size.height;
CGFloat requiredWidth = (imageWidth * size.height) / imageHeight;
UIGraphicsBeginImageContextWithOptions(CGSizeMake(requiredWidth, size.height), NO, [UIScreen mainScreen].scale);
[image drawInRect:CGRectMake(0, 0, requiredWidth, size.height)];
UIImage* newImage = UIGraphicsGetImageFromCurrentImageContext();
//here is the scaled image which has been changed to the size specified
UIGraphicsEndImageContext();
return newImage;
}

I was facing something very similar issue few days back. I was trying to set larger dimension image in smaller dimension UIImageView using resizeImage method as mentioned in one of the answer here. But it could not solve my problem. So here is what I used to solve my problem,
yourImageView.contentMode = UIViewContentModeCenter;
[yourImageView setClipsToBounds:YES];
OR
[yourImageView setContentMode:UIViewContentModeScaleAspectFill];
yourImageView.autoresizingMask = ( UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight );
[yourImageView setClipsToBounds:YES];
Yes it will not scale your image, but your image would not be squished. I solved my problem using this, hopes it might solve your problem.
