courses, credits , points ruby arrays equal size. gpa = (([credits, courses, points].transpose.map {|x| x.reduce(:*)}).inject{|sum,x| sum + x }).round(2) this method prompted error message when trying run it. error message: in 'each': undefined method '*' nil:nilclass (nomethoderror) from error message, seems of data nil . perhaps can attempt force data floats. it's not ideal, might end silent errors, it's worth shot. try: [credits, courses, points].transpose.map {|a| a.map {|n| n.to_f} } .map { |x| x.reduce(:*) } .inject{|sum, x| sum + x} .round(2) it works me strings , weird data (although incompatible data converted zeros, effecting math).

i have custom toolbox foo element. i foo green on class diagram , red on flow chart diagram default. adding more 1 stereotype non- uml type impossible (as far know). is possible create 2 toolboxes- 1 class diagrams , 1 flow charts, specifying default diagram each toolbox in profile? not quite way describe it. toolboxes don't specify diagram open, it's other way around: create custom diagram type , associate toolbox. different custom diagrams may use same custom toolbox. you can create 2 custom diagram types, 1 class ("logical") , 1 flow chart ("activity"), if you're after getting same stereotyped element ( foo ) display differently in diagrams, don't need to. the solution create shape script stereotype, checks diagram type , changes color accordingly. diagram type can queried shape script using diagram.type property (for base uml diagram type), or diagram.mdgtype (for custom diagram type, if you've defined one). th

in 1 of wwdc videos, apple said layout done top down, ie superview subview (after constraints calculated bottom up). display done top down. my questions are: 1. @ point in viewcontroller view's frame (origin , size) determined? tried log size of view (defined using auto layout), 0 0 0 0, odd, because view generated in simulator; for autoresized view, when view.frame available? same question, except time uiimageview.frame. tried log console, though size fit constraints, logged uiimageview frame 0 0 width_of_original_image height_of_original_image. other views labels, frame printed correctly on console. it seems there mysterious auto layout engine performs transform, , nobody knows going on inside engine, check thrown onto simulator display figure out how view rendered engine??? it's not mysterious. it's quite simple! think of constraints instructions written down on pieces of paper - views. every once in while, it's layout time! runtime collects
