带有stretchableImageWithLeftCapWidth的UIImageView不会拉伸图像 [英] UIImageView with stretchableImageWithLeftCapWidth doesn't stretch image

问题描述

我正在尝试在UIImageView中拉伸一个图像 - 但我失败了：）

I'm trying to stretch an Image in a UIImageView - but I fail miserably :)

以下设置：

带有视图的NIB-File和附加到此视图的UIImageView。

NIB-File with a view and a UIImageView attached to this view.

使用 IBOutlet UIImageView * background 。

现在，在我的课程中，我尝试以下方法：

Now, in my class I try the following:

UIImage *bgImage = [[UIImage imageNamed:@"myImage.png"] stretchableImageWithLeftCapWidth:0 topCapHeight:50];
[background setImage: bgImage];

bgFrame = CGRectMake(0, 0, 250, 200);
background.frame = bgFrame;

应垂直拉伸图像 - 至少，这就是我的想法。唉，它没有用...... :(

which should stretch the image vertically - at least, that's what I thought. Alas, it's not working... :(

我正在使用的图像高度为115px（这对于拉伸应该足够了，我猜？） / p>

The image I'm using has a height of 115px (which should be enough for the stretch, I guess?)

推荐答案

知道了......（有趣的是，在提问后几秒钟就会发生这种情况）

Got it... (interesting that this happens often just seconds after asking the question)

在IB中，我不得不将UIImageView中的模式设置为«Scale to fill»并设置Autoresize-property

In IB, I had to set the mode in the UIImageView to «Scale to fill» and set the Autoresize-property

这就解决了问题...

That's what solved the problem...

希望能帮到某人;）
