我想用 UIImage
设置 UIImageView 并将这个 imageview 放在 UIScrollView
中以获得这个图像的缩放;我希望这个 UIImageView
和 UIScrollView
适合视图中心的矩形...有可能吗?
<UIScrollViewDelegate>
UIScrollView
绘制为视图中心矩形所需的大小.将检查器中的最大缩放设置为大于 1 的值.例如 4 或 10.UIScrollView
中绘制您的 UIImageView
并使用您想要的任何图像进行设置.使其与 UIScrollView
的大小相同.UIImageView
拖动到 View 控制器的 .h
中,为 UIImageView
创建一个 IBOutlet
code>,把它称为 imageView
之类的聪明东西.添加此代码:
<块引用>-(UIView *) viewForZoomingInScrollView:(UIScrollView *)scrollView{返回self.imageView;}
运行应用程序并捏合和平移,直到心满意足.
I want to set a UIImageView with a UIImage
and put this imageview inside a UIScrollView
to obtain a zoom of this image;
and I want this UIImageView
and UIScrollView
to fit in the rect at the center of the view...is it possible?
<UIScrollViewDelegate>
UIScrollView
the size you want for the rectangle at the center of the view. Set the max zoom in the inspector to something bigger than 1. Like 4 or 10.UIImageView
in the UIScrollView
and set it up with whatever image you want. Make it the same size as the UIScrollView
.UIImageView
to the .h
of your View controller to create an IBOutlet
for the UIImageView
, call it something clever like imageView
.Add this code:
-(UIView *) viewForZoomingInScrollView:(UIScrollView *)scrollView { return self.imageView; }
Run the app and pinch and pan til your heart's content.
