如何开始这个目标C动画？

Question

刚开始学习为iOS编程，有一个非常简单的问题，但无法弄明白。

UIImage *image = [UIImage imageNamed:@"robot.png"];
UIImageView *imageView = [[UIImageView alloc] initWithImage:image];

/* Write your code below this line */

NSArray *robotImages = [[NSArray alloc] initWithObjects:[UIImage imageNamed:@"Robot1.png"],
        [UIImage imageNamed:@"Robot2.png"],
        [UIImage imageNamed:@"Robot3.png"],
        [UIImage imageNamed:@"Robot4.png"], nil];
imageView.animationImages = robotImages;
imageView.animationDuration = 5.0;

Answer 1

现在真的[imageView startAnimating];
