Implementing auto layout for views generated programmatically

Question

I have an app whose views are generated programmatically. Example:

-(void)loadView
{
    [super loadView];

// SET TOP LEFT BTN FOR NEXT VIEW
UIBarButtonItem         


        

Answer 1

In addition to Aplle provided methods you can use Parus lib for operating with AutoLayout from code.

For example you will be able to specify:

PVVFL(@"[view1]-20-[view2]").fromRightToLeft.withViews(views).asArray

Instead of

[NSLayoutConstraint constraintsWithVisualFormat:@"[view1]-20-[view2]"
                                        options:NSLayoutFormatDirectionRightToLeft
                                        metrics:nil
                                          views:views]

Also you will be able to group layouts settings, mix VFL and not VFL constraints. Parus able to prevent common mistakes, differentiate location and parameters constriaints, and provide great auto-completion support.
