Tutorial 3: Embed xml layout into traditional view hierarchy

Write xml layout file

Use FlexFrameView to load it.

    CGRect rcFrame = CGRectMake(0, 0, [[UIScreen mainScreen] bounds].size.width, 0);
    FlexFrameView* header = [[FlexFrameView alloc]initWithFlex:@"TableHeader" Frame:rcFrame Owner:self];
    header.flexibleHeight = YES;
    [header layoutIfNeeded];
    
    _table.tableHeaderView = header;

You can set fixed frame to it or make it flexible.

If the view is flexible, you can get notification with onFrameChange block when the view size changed.
