ios - 设置 View 的背景颜色时如何避免平铺？

Question

我正在尝试为我的应用程序设置背景图像，但该图像是平铺的。我该如何防止这种情况？我希望我的图像适合背景。

在CSS中我会设置NO-REPEAT；有类似的东西吗？

我尝试过这段代码:

-(IBAction)btnAddBackground
{
    self.view.backgroundColor = [[UIColor alloc] initWithPatternImage:[UIImage imageNamed:@"image.jpg"]];
}

documentation for UIView对此提出几点建议:

• Image-based backgrounds - For views that display relatively static content, consider using a UIImageView object with gesture recognizers instead of subclassing and drawing the image yourself. Alternatively, you can also use a generic UIView object and assign your image as the content of the view’s CALayer object.
