iOS Swift Segues -

-

what want: when i'm on green screen , push button "pushtobrown" want brown screen "think" i'm coming blue. if push button in brown screen want go blue.

at moment: call green screen programmatically example performseguewithidentifier(..., nil) , can switch brown or implement drag&drop (from button "pushtobrown" brownvc screen). if push "back button" go green. -> how can tell brown should go blue?

segue example

i suppose that's problem navigation controller. me if know tutorials segues or navigationcontroller handlding.

thanks in advance!

the solution problem unwind segue : what unwind segues , how use them?

what should ( can see in link ) add exit point, create unwind method , call 1 instead of simple popviewcontroller. first answer contains both explanation, code examples, , both objective-c , swift

javascript - How to diff two immutable objects -

-
is there way diff objects in immutable ? example: let = immutable.fromjs({ a: 10 }); let b = immutable.fromjs({ b: 10 }); let d = immutable.diff(a, b); // { a: 10 } console.log(d.tojs()); this useful when testing see how objects differ. it doesn't have show what's added/removed explicitly. want see properties a differs b can make them equal again. for example this: console.log(a.tojs()); console.log(b.tojs()); and check logs see differs b. in other thought might show both added , removed properties in same output. main point see not equal. so be: // { a: 10, b: 10 } console.log(d.tojs()); or maybe: // { added: { a: 10 }, removed: { b: 10 } } // console.log(d.tojs());
