I run my app in ios simulator with different simulators for ios 7.0 (Iphone Retina 3.5 inch , Iphone Retina 4 inch , Iphone Retina 4 inch 64-bit) and i check the device bounds. According to the bounds i place the components of each viewcontroller to specific positions. Although today i tried to run my app in different version of ios(ios 6.0) and items seem to be repositioned by own at wrong positions although screen has the same bounds. Here is the method that handles the position of components.
     if(self.view.bounds.size.height==480){
        self.view.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"background2.png"]];
        float positionScrollBar= self.view.bounds.size.height-72;
        _scroller.frame = CGRectMake(0, positionScrollBar, 320, 72);
        _scroller.contentSize = CGSizeMake(450, 0);
        _scroller.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"toolbar.png"]];
        [self.logo setFrame:CGRectMake(30,100,260,260)];
        int xCoord=10;
        int yCoord=10;
        int buttonWidth=50;
        int buttonHeight=50;
        int buffer = 22;
        self.grBtn.frame = CGRectMake(xCoord,yCoord, buttonWidth, buttonHeight);
        xCoord += buttonWidth + buffer;
        self.enBtn.frame = CGRectMake(xCoord,yCoord, buttonWidth, buttonHeight);
        xCoord += buttonWidth + buffer;
        self.frBtn.frame = CGRectMake(xCoord,yCoord, buttonWidth, buttonHeight);
        xCoord += buttonWidth + buffer;
        self.gerBtn.frame = CGRectMake(xCoord,yCoord, buttonWidth, buttonHeight);
        xCoord += buttonWidth + 10;
        self.rightArrowBtn.frame = CGRectMake(xCoord,15, 27, 44);
        xCoord += buttonWidth-4;
        self.leftArrowBtn.frame = CGRectMake(xCoord,15, 27, 44);
        xCoord += buttonWidth;
        self.ispBtn.frame = CGRectMake(xCoord,yCoord, buttonWidth, buttonHeight);
        xCoord += buttonWidth + buffer;
        self.ruBtn.frame = CGRectMake(xCoord,yCoord, buttonWidth, buttonHeight);
        xCoord += buttonWidth + buffer;
        self.itBtn.frame = CGRectMake(xCoord,yCoord, buttonWidth, buttonHeight);
        xCoord += buttonWidth + 55;
        _scroller.contentSize = CGSizeMake(xCoord, 0);
        self.rightArrowBtn.hidden=NO;
        self.leftArrowBtn.hidden=NO;
    }
    else
    {
        self.view.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"background2.png"]];
        float positionScrollBar= self.view.bounds.size.height-72;
        _scroller.frame = CGRectMake(0, positionScrollBar, 320, 72);
        _scroller.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"toolbar.png"]];
        [self.logo setFrame:CGRectMake(20,150,280,280)];
        int xCoord=10;
        int yCoord=10;
        int buttonWidth=50;
        int buttonHeight=50;
        int buffer = 22;
        self.grBtn.frame = CGRectMake(xCoord,yCoord, buttonWidth, buttonHeight);
        xCoord += buttonWidth + buffer;
        self.enBtn.frame = CGRectMake(xCoord,yCoord, buttonWidth, buttonHeight);
        xCoord += buttonWidth + buffer;
        self.frBtn.frame = CGRectMake(xCoord,yCoord, buttonWidth, buttonHeight);
        xCoord += buttonWidth + buffer;
        self.gerBtn.frame = CGRectMake(xCoord,yCoord, buttonWidth, buttonHeight);
        xCoord += buttonWidth + 10;
        self.rightArrowBtn.frame = CGRectMake(xCoord,15, 27, 44);
        xCoord += buttonWidth-4;
        self.leftArrowBtn.frame = CGRectMake(xCoord,15, 27, 44);
        xCoord += buttonWidth;
        self.ispBtn.frame = CGRectMake(xCoord,yCoord, buttonWidth, buttonHeight);
        xCoord += buttonWidth + buffer;
        self.ruBtn.frame = CGRectMake(xCoord,yCoord, buttonWidth, buttonHeight);
        xCoord += buttonWidth + buffer;
        self.itBtn.frame = CGRectMake(xCoord,yCoord, buttonWidth, buttonHeight);
        xCoord += buttonWidth + 55;
        _scroller.contentSize = CGSizeMake(xCoord, 0);
        self.rightArrowBtn.hidden=NO;
        self.leftArrowBtn.hidden=NO;
    }
I do not use Auto-Layout and i can not use it.
Any advice is appreciated.
