Resolved: iOS, Objective-C Declaring Variable to entire Class.

[resetme]

Hi guyz,

i'm new here and i have one doubt about creating variables.

I have a variable that get the screen size of the device declared inside a method, but i need it to be out of the scope to all my methods inside the same class (just for the same class).

I dont want to pass it by arguments to every method, so i need a private visible variable for this class.

How can i do that?
Right now i have:

I declared it only in the .m file

@interface ViewController ()

@end

@implementation ViewController
@synthesize seleccion,button1,button2,button3;

static CGRect screenBound;
static CGFloat screenWidth;
static CGFloat screenHeight;

- (void)viewDidLoad
{

    //Get Screen Size
    screenBound = [[UIScreen mainScreen] bounds];
    screenWidth = screenBound.size.width;
    screenHeight = screenBound.size.height;

   //Lot of methods who use the screen size here 
   bla bla bla

}

It's that correct? i never use static in C#, for me static means visible for ALL class and i dont want that, i just need it for this class. also... it's there a problem for not declaring it at my .h file?

Thanxs!

Yes, that's correct. In Objective-C, static does not mean visible for ALL classes.

ty!


hey, do u know how to delegate?

i need to call a function in class B from classA when an animation is over.


classA:

[UIView animateWithDuration:animateDuration
                          delay:animateDelay
                        options: UIViewAnimationCurveEaseOut
                     animations:^{
                         CGRect frame = obj.frame;
                         frame.origin.x = posX;
                         frame.origin.y = posY;
                         obj.frame = frame;

                     }
                     completion:^(BOOL finished){
                         NSLog(@"Done!");
                         ----> hey CLASS B im DONE do something!
   
                     }
     ];

classB
import classA

-(void)doSomeThing{
}


Srry for asking twice :/

no problem!

i used protocol and delegate!

completion:^(BOOL finished){
                         NSLog(@"Done!");
                         if([obj isKindOfClass:[UIButton class]]){
                             [self.delegate animationDone:(UIButton *)obj];
                         }
                     }
