三、图像移动《苹果iOS实例编程入门教程》

该app为应用的功能为动态移动动画

现版本 SDK 8.4 Xcode

运行Xcode 选择 Create a new Xcode project ->Single View Application 命名 movingImage

(1)  在xCode打开 ViewController.m 文件

(红色为所添加的代码)

// Do any additional setup after loading the view, typically from a nib.

//定义图片的位置和尺寸,位置:x=10.0f, y=10.0f ,尺寸:x=50.0f, y=40.0f

UIImageView *subView = [[UIImageView alloc]initWithFrame:CGRectMake(10.0f, 10.0f, 50.0f, 40.0f)];

//设定图片名称,lovely mouse.png已经存在，拖放添加图片文件到项目Supporting Files文件夹中

[subView setImage:[UIImage imageNamed:@"lovely mouse.png"]];

//启用动画移动

[UIImageView beginAnimations:nil context:NULL];

//移动时间4秒

[UIImageView setAnimationDuration:4];

//图片持续移动

[UIImageView setAnimationBeginsFromCurrentState:YES];

//重新定义图片的位置和尺寸,位置

subView.frame = CGRectMake(100.0, 150.0, 200.0, 160.0);
