ios - How can I change the text from another view controller? -

i'm trying

signupviewcontroller *useremail=[[signupviewcontroller alloc] init]; useremail.emailaddress.text=email;

but not working.

it seems emailaddress (assuming uitextfeild) not allocated when called

signupviewcontroller *useremail=[[signupviewcontroller alloc] init];

so, nil @ point of init.

better way be, added 1 public property in signupviewcontroller of nsstring. save value in property. below

signupviewcontroller *useremail=[[signupviewcontroller alloc] init]; useremail.emailstring=email;

in signupviewcontroller.h file add

@property (nonatomic, strong) nsstring *emailstring;

in signupviewcontroller.m file in view did load

- (void)viewdidload{   //if have not used nib or stroyboard init textfield first  emailaddress.text=emailstring;   }
