Question

I want to add a subview in the top of my view, I have to recalculate the origin y value for all of other views and re-position them to leave space for the new added view.

I've created a library to solve just this problem: CSLinearLayoutView

You use it like this:

// create the linear layout view
CSLinearLayoutView *linearLayoutView = [[[CSLinearLayoutView alloc] initWithFrame:self.view.bounds] autorelease];
linearLayoutView.orientation = CSLinearLayoutViewOrientationVertical;
[self.view addSubview:linearLayoutView];

// create a layout item for the view you want to display and add it to the layout view
CSLinearLayoutItem *item = [CSLinearLayoutItem layoutItemForView:someView];
item.padding = CSLinearLayoutMakePadding(5.0, 10.0, 5.0, 10.0);
item.horizontalAlignment = CSLinearLayoutItemHorizontalAlignmentCenter;
item.fillMode = CSLinearLayoutItemFillModeNormal;
[linearLayoutView addItem:item];

// add more items
