IOS: view. Frame

We know that view. frame is in the coordinate space of the parent container of the current view. I put only one view in one viewcontroller on the iPad, and only one webview (interface landscape) is included in the view. I wanted to reach the contentsize of webview, so ICodeAdd:

View code

Nslog (@"Self. View. frame is % @", Nsstringfromcgrect (self. View. Frame); nslog (@"Self. webview. frame is % @", Nsstringfromcgrect (self. webview. Frame); nslog (@"Webview. scrollview. contentsize is % @", Nsstringfromcgsize (webview. scrollview. contentsize); nslog (@"Webview. scrollview. frame is % @", Nsstringfromcgsize (webview. scrollview. Frame. Size ));
 

However, the output is:

Self. View. frame is {0, 20}, {768,100 4 }}

Self. webview. frame is {0, 0}, {768,100 4 }}

Webview. scrollview. contentsize is {1024,100 4}

Webview. scrollview. Frame. size is {100,100}

It is totally different from the logic.

Originally, I put the above Code in viewdidload. After playing the view in nib or storyboard in the system value, I immediately called viewdidload. At this time, the system did not load the content in it, I still don't know the direction or anything.

After I put the code in the loaded place, the correct ones should be:

Self. View. frame is {20, 0}, {748,102 4 }}

Self. webview. frame is {0, 0 },{ 1024,748 }}

Webview. scrollview. contentsize is {5944,748}

Webview. scrollview. Frame. size is {1024,748}

 

Note that the coordinate system of the uiwindow has always been erected.
