Answer of my own Question : After many efforts i found the answer of both of my questions.

and it work good for me. I share here, may be it help someone. :)

1) Fit image View inside Scroll View. I use this link

- (void)centerScrollViewContents {

CGSize boundsSize = scroll.bounds.size;
CGRect contentsFrame = self.imageView1.frame;

if (contentsFrame.size.width < boundsSize.width) {
contentsFrame.origin.x = (boundsSize.width - contentsFrame.size.width) / 2.0f;
} 
else {
contentsFrame.origin.x = 0.0f;
}

if (contentsFrame.size.height < boundsSize.height) {
    contentsFrame.origin.y = (boundsSize.height - contentsFrame.size.height) / 2.0f;
} 
else {
contentsFrame.origin.y = 0.0f;
}

self.imageView1.frame = contentsFrame;
}

2) Crop a zoomed Image in inside scrollView. I use this link

    UIGraphicsBeginImageContext(CGSizeMake(200, 200));

    [scroll.layer renderInContext:UIGraphicsGetCurrentContext()];

    UIImage *fullScreenshot = UIGraphicsGetImageFromCurrentImageContext();

    UIGraphicsEndImageContext();

    imageView1.contentMode = UIViewContentModeScaleAspectFill;

    UIImageWriteToSavedPhotosAlbum(fullScreenshot, nil, nil, nil);

    return fullScreenshot;
