ios - UIButton modifying titlelabel seems to change its frame -

-

something strange happening. basically, trying recreate messaging app. when trying send button change grey blue when user has typed in @ least 1 character.

the problem comes when trying change titlelabel, button disappear. later found out reverts old position (when keyboard not shown).

why this? if not modify titlelabel works usual. however, if do, uibutton goes original location. if need sample code let me know, not sure put on here it's [self.button.titlelabel settextcolor: [uicolor bluecolor]; in uitextviewdidchange it's acting strange.

thanks! alan

you might fighting against auto-layout. saw similar behavior, , answered question here: why uibutton resize when access titlelabel property?. basically, suggested forego auto-layout or only use auto-layout (never set frames programmatically).

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.
