mapkit - Creating a dynamic MKAnnotationView in Swift -

-

currently, know how create mkannotationview static pin, image that's added.

does know, or have resources, on how create pin change colors or have number displayed inside of change depending on information business?

for instance, have pin red when business closed, , green when business open. maybe dollar signs inside of pin tell user how expensive is.

edit

i have created class called custompin adopts mkannotation protocol. additionally, i'm not looking have custom mkannotationview image can change. mean i'll have add multiple images mkannotationview in array , have change image everytime details business change?

thank in advance!

you can create custom mkannotationview inheritance. can use class create annotation view delegate method.

here 1 example.

class kdannotationview: mkannotationview {      let titlelabel = uilabel()      convenience init(annotation: mkannotation?) {         self.init(annotation: annotation, reuseidentifier: "indetifier")         self.canshowcallout = false         self.frame = cgrectmake(0, 0, 75.0, 85.0)         self.backgroundcolor = uicolor.clearcolor()         self.centeroffset = cgpointmake(0, 0)          self.titlelabel.backgroundcolor = uicolor.clearcolor()         self.titlelabel.textcolor = uicolor.blackcolor()         self.titlelabel.font = uifont.systemfontofsize(16.0)         self.addsubview(self.titlelabel)     }       override func layoutsubviews() {         super.layoutsubviews()          var frame = cgrectinset(self.bounds, 5.0, 5.0)             frame.size.height = 20.0         self.titlelabel.frame = frame     }       override func drawrect(rect: cgrect) {         super.drawrect(rect)           let path = uibezierpath()         path.movetopoint(cgpoint(x: cgrectgetminx(rect), y: cgrectgetminy(rect)))         path.addlinetopoint(cgpoint(x: cgrectgetmaxx(rect), y: cgrectgetminy(rect)))         path.addlinetopoint(cgpoint(x: cgrectgetmaxx(rect), y: cgrectgetmaxy(rect) - 10.0))         path.addlinetopoint(cgpoint(x: cgrectgetmidx(rect) + 5.0, y: cgrectgetmaxy(rect) - 10.0))         path.addlinetopoint(cgpoint(x: cgrectgetmidx(rect), y: cgrectgetmaxy(rect)))         path.addlinetopoint(cgpoint(x: cgrectgetmidx(rect) - 5.0, y: cgrectgetmaxy(rect) - 10.0))         path.addlinetopoint(cgpoint(x: cgrectgetminx(rect), y: cgrectgetmaxy(rect) - 10.0))         path.closepath()         uicolor.lightgraycolor().setstroke()         uicolor.whitecolor().setfill()         path.stroke()         path.fill()      }       //mark: - public methods     func settext(text:string) {         self.titlelabel.text = text     } }

java - Copying object fields -

-
what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
