Animate Logo就像Skype iPad App一样

Question

我正在构建一个我需要动画徽标的应用程序,就像skype应用程序一样.我仍然不确定如何在启动应用程序时显示影响skype徽标

Answer 1

至于我对你的问题的理解,你可以尝试使用帧图像(gif图像帧精确)UIImageView.

 NSArray * imageArray  = [[NSArray alloc] initWithObjects:[UIImage imageNamed:@"1.png"], [UIImage imageNamed:@"2.png"], nil]; //this will be the frames of animation images in sequence.
 ringImage = [[UIImageView alloc]initWithFrame:CGRectMake(100,200,600,600)];
 ringImage.animationImages = imageArray;
 ringImage.animationDuration = 1.5;//this the animating speed which you can modify
 ringImage.contentMode = UIViewContentModeScaleAspectFill;
 [ringImage startAnimating];//this method actually does the work of animating your frames.

要停止动画,只需使用 [ringImage stopAnimating];

如果这回答了你的问题,请告诉我:)
