如何在不拉伸中心的情况下拉伸UIImageView？ [英] How to stretch a UIImageView without stretching the center?

问题描述

我想要拉伸上图所示图片的左右两侧，并保持中间箭头未拉伸。我该怎么做？

I want to stretch the left and right sides of the picture shown above, and keep the middle arrow unstretched. How can I do that?

推荐答案

使用Photoshop或其他图像编辑工具将图像分成两部分：边缘和中心。边缘图像可以是一个像素宽并用于左右边缘;然而，中心有很多像素宽，可以捕捉箭头。然后，您可以将三个 UIImageView 实例彼此相邻：左边缘，中心边缘和右边缘。左右边缘调整为所需宽度，而中心保持原始尺寸。

Use Photoshop or another image editing tool to split the image into two pieces: edge and center. The edge image can be one pixel wide and used for left and right edges; the center is however many pixels wide that capture the arrow. You can then put three UIImageView instances next to each other: left edge, center, and right edge. The left and right edges are resized to the desired width, while the center keeps its original dimensions.
