how can i set all variables from my NSMutableArray to zero?

I want to set integer variables that I have put in an NSMutableArray to zero, here is my code so far but it doesn't work:

[self.pressCountArray addObject:[NSNumber numberWithInt:self.presscount1]];
[self.pressCountArray addObject:[NSNumber numberWithInt:self.presscount2]];
[self.pressCountArray addObject:[NSNumber numberWithInt:self.presscount3]];
[self.pressCountArray addObject:[NSNumber numberWithInt:self.presscount4]];
[self.pressCountArray addObject:[NSNumber numberWithInt:self.presscount5]];

for (NSInteger i = 0; i < [self.pressCountArray count]; i++){

    [[self.pressCountArray objectAtIndex:i] integerValue]  == 0;

}

You are comparing integer value with 0 and not assigning.

Just this code can accomplish your task

self.pressCountArray[i] = @0;

[self.pressCountArray objectAtIndex:i] integerValue] == 0

compares the current value with zero. To set a new value, use just

self.pressCountArray[i] = @0;

@0 is a "NSNumber literal" and equivalent to [NSNumber numberWithInt:0], see http://clang.llvm.org/docs/ObjectiveCLiterals.html.

You can also simplify your existing code with "boxed expressions":

[self.pressCountArray addObject:@(self.presscount1)];
// ...
