我是基於教程開發在Android上的變焦控制：Android one finger zoom tutorial public abstract class Dynamics {
/**
* The maximum delta time, in milliseconds, between two updates
*/
private static final int MAX_TIMESTEP
我在UIScrollView中有一個UIImageView。我希望用戶可以縮放和導航圖像。 這是我的工作代碼： //img is the UIImageView
//scroller is the UIScrollView
- (UIView *)viewForZoomingInScrollView:(UIScrollView *)scrollView {
return img;
}
