恢复和移转核心电文(CAKeyFrameation)
原标题:Resize and move a UIView with Core Animation (CAKeyFrameAnimation)

这是可能的吗? 我可以改变该层的不透明性和立场(中心),但只要我试图改变面积或原产地,那就没有工作。

    CAAnimationGroup* anigroup = [CAAnimationGroup new];

    CGMutablePathRef thePath = CGPathCreateMutable();
    CGPathAddRect(thePath, NULL, CGRectMake(0,0, 320, 480));
    CGPathAddRect(thePath, NULL, CGRectMake(location.x - 16,location.y-24, 32, 48));
    CGPathAddRect(thePath, NULL, CGRectMake(190, 20, 32, 48));


    CAKeyframeAnimation* AniLoc = [CAKeyframeAnimation animationWithKeyPath:@"frame"];
    AniLoc.path = thePath;
    AniLoc.keyTimes= [NSArray arrayWithObjects:[NSNumber numberWithFloat:0.0f],
                                             [NSNumber numberWithFloat:0.3f],
                                             [NSNumber numberWithFloat:1.0f],nil];
    AniLoc.duration = 5;

    CFRelease(thePath);

    anigroup.animations = [NSArray arrayWithObjects:AniLoc,nil];
    anigroup.duration = 5;

    [focusview.layer addAnimation:anigroup forKey:nil];
