Question

In Safair mobile you can zoom in by double taping if you have a html page that you display. But if you use a uiwebview and display an image or pdf file you have to pinch open to zoom.

我的问题是:我必须做些什么,在展示形象或pdf档案时,把双管放在一起工作?

Can you make the uiwebview a sub view under a uiscrollview, will you then be able to double tap an zoom? And how would you do that?

Answer 1

移动电话的双管线是focus内容。它将找到<代码>div。页: 1 这不是仅仅双管齐下。

Answer 2

若要从IDWebview u中取得双管线,就必须将IDWindow分类并使用这种方法,

- (void)sendEvent:(UIEvent *)event {
    NSLog(@"tap detect");
    NSArray *allTouches = [[event allTouches] allObjects];
    UITouch *touch = [[event allTouches] anyObject];
    UIView *touchView = [touch view];

    if (touchView && [touchView isDescendantOfView:urWebview]) {
        //
        // touchesBegan
        //
               if(touch.tapCount==2){
                     //
                // doubletap
                //
               }
       }
}
