IOS开发（17）之UIImageView控件

1 前言

2 代码实例

@synthesize myImageView;

- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
UIImage *macBook = [UIImage imageNamed:@"Apple.png"];
//    myImageView = [[UIImageView alloc] initWithImage:macBook];//不改变图片的长宽比例
myImageView = [[UIImageView alloc] initWithFrame:self.view.frame];//使图片适应整个视图窗
myImageView.image = macBook;
myImageView.center = self.view.center;
[self.view addSubview:myImageView];

}
