Answer 1

你要找的是Ken Burns Effect或Panning

下面是应用它的代码。

        [UIView beginAnimations:nil context:NULL];
        [UIView setAnimationDuration:7];

        [UIView setAnimationCurve:UIViewAnimationCurveEaseIn];
        CGAffineTransform rotate = CGAffineTransformMakeRotation(0.00);
        CGAffineTransform moveLeft = CGAffineTransformMakeTranslation(0.9,0.9);
        CGAffineTransform combo1 = CGAffineTransformConcat(rotate, moveLeft);

        CGAffineTransform zoomOut = CGAffineTransformMakeScale(1.1,1.1);
        CGAffineTransform transform = CGAffineTransformConcat(zoomOut, combo1);
        background.transform = transform;
        [UIView commitAnimations];

快乐编码:)
