    <p>I have add a webview,a titleLabel and a coverflowView on a viewcontroller's view as its subviews, I want it to change size when the orientation change. I have change the webview's frame in this method: </p> <pre><code> - (void)willRotateToInterfaceOrientation: (UIInterfaceOrientation)toInterfaceOrientation duration: (NSTimeInterval)duration </code></pre> <p>its content did resize when rotate iPad from orientationLandscape to orientationPortrait or from orientationPortrait to orientationLandscape if I start the application with portrait orientation, but it is so strange that its content dosen't resize when I start the application with landscape orientation...But the NSLog shows the frame has changed. As to the titleLabel and the coverflowView, they resize correctly. I doubt if it is because of css?I have use css to control the content's style according to the height and width of webview.Does anyone could help me to find the reason? the code is below:</p> <pre><code>- (void)willRotateToInterfaceOrientation: (UIInterfaceOrientation)toInterfaceOrientation duration: (NSTimeInterval)duration { double i = 0; NSInteger width=self.view.frame.size.width; NSInteger height=self.view.frame.size.height; NSLog(@"view :%@",[self.view description]); switch (toInterfaceOrientation){ case UIInterfaceOrientationPortrait: { NSLog(@"rotate to Portrait");

    1. COI've got this exact same issue. If the app starts in Portrait mode. the UIWebView Correctly adjusts the size and my CSS shows it has changed. If I start it in Landscape mode, it doesn't change anymore.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
