使用resizeableImageWithCapInsets:resizingMode来平铺UIImageView吗? [英] Tiling a UIImageView using resizeableImageWithCapInsets:resizingMode?

问题描述

我正在使用以下代码尝试创建带有盖帽插图的平铺图像，并在模拟器中看到下面的图像作为结果.我的源图像的尺寸为145x83像素，并且也在此处显示.我在做什么错了?

I'm using the following code to try to create a tiled image with cap insets, and seeing the image below as the results in the simulator. My source image is 145x83 pixels in size, and shown here too. What am I doing wrong?

源图像:

模拟器结果:

代码:

- (void)viewDidLoad
{
    [super viewDidLoad];

    UIImage *cloudImage = [UIImage imageNamed: @"cloud.png"];
    [cloudImage resizableImageWithCapInsets: UIEdgeInsetsMake(10, 10, 10, 10) resizingMode: UIImageResizingModeTile];

    UIImageView *imageView1 = [[UIImageView alloc] initWithImage: cloudImage];
    [imageView1 setFrame: CGRectMake(50, 50, 100, 100)];

    UIImageView *imageView2 = [[UIImageView alloc] initWithImage: cloudImage];
    [imageView2 setFrame: CGRectMake(250, 50, 200, 200)];

    [self.view addSubview: imageView1];
    [self.view addSubview: imageView2];

}

推荐答案

您未将可调整大小的图像分配给任何对象，您需要执行以下操作:

You are not assigning the resizable image to anything, you need to either do:

UIImage *cloudImage = [[UIImage imageNamed: @"cloud.png"] resizableImageWithCapInsets: UIEdgeInsetsMake(10, 10, 10, 10) resizingMode: UIImageResizingModeTile];

或

cloudImage = [cloudImage resizableImageWithCapInsets: UIEdgeInsetsMake(10, 10, 10, 10) resizingMode: UIImageResizingModeTile];
