IOS开发（17）之UIImageView控件

1 前言
显示给用户图片视图，其视图大小控制比较麻烦

2 代码实例
ZYViewController.m：

[plain]
@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];

}

@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];

}
