問題描述

我想用 UIImage 設(shè)置 UIImageView 并將這個 imageview 放在 UIScrollView 中以獲得這個圖像的縮放；我希望這個 UIImageView 和 UIScrollView 適合視圖中心的矩形...有可能嗎?

1. 將您的視圖控制器設(shè)置為 <UIScrollViewDelegate>
2. 將 UIScrollView 繪制為視圖中心矩形所需的大小.將檢查器中的最大縮放設(shè)置為大于 1 的值.例如 4 或 10.
3. 右鍵單擊滾動視圖并將代理連接到您的視圖控制器.
4. 在 UIScrollView 中繪制您的 UIImageView 并使用您想要的任何圖像進(jìn)行設(shè)置.使其與 UIScrollView 的大小相同.
5. Ctrl + 將 UIImageView 拖動到 View 控制器的 .h 中，為 UIImageView 創(chuàng)建一個 IBOutletcode>，把它稱為 imageView 之類的聰明東西.

6. 添加此代碼:

   <塊引用>

   -(UIView *) viewForZoomingInScrollView:(UIScrollView *)scrollView{返回self.imageView；}

7. 運(yùn)行應(yīng)用程序并捏合和平移，直到心滿意足.

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?

1. Set your view controller up as a <UIScrollViewDelegate>
2. Draw your 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.
3. Right click on the scroll view and connect the delegate to your view controller.
4. Draw your UIImageView in the UIScrollView and set it up with whatever image you want. Make it the same size as the UIScrollView.
5. Ctrl + drag form you UIImageView to the .h of your View controller to create an IBOutlet for the UIImageView, call it something clever like imageView.

6. Add this code:

   -(UIView *) viewForZoomingInScrollView:(UIScrollView *)scrollView
   {
       return self.imageView;
   }
   

7. Run the app and pinch and pan til your heart's content.
