Did you try?

@import AVFoundation; 

UIImageView *image = [[UIImageView alloc] init];
image.image = [UIImage imageNamed:@"paint5.png"];
CGRect yourFrame = AVMakeRectWithAspectRatioInsideRect(imageView.image.size, imageView.bounds);
NSLog(@"%@",NSStringFromCGRect(yourFrame));

I think thats what u are looking for.

You can get height and width of image in following way:

UIImageView *image = [[UIImageView alloc] init];
image.image = [UIImage imageNamed:@"paint5.png"];
int imgHeight =  image.layer.frame.size.height;
int imgWidth = image.layer.frame.size.width;
NSLog(@"height of image %i",imgHeight);
NSLog(@"widht of image %i",imgWidth);
