What is the need to resize subviews programmatically when using storyboards?

问题

I am well versed with custom views. Today I have started using storyboards & I am not able to convince myself on the usage of storyboard.

Problem: - I have set up by View Controller in storyboard. - Running on simulator 4 inch, I am good to Go with the layouts of Views. - Running on simulator 3.5 inch, I am upset, as my view is partially visible.

Here are screen shots.

My SotryBaord (Look at the "Delete User" Button).
Delete User button frame:
Running on Simulator 4 inch
Running on Simulator 4 inch (I have problem)

how do I get the frame adjusted with layouts so that it runs clear in both size iPhones. My delete user button should not go off the screen.

Mate, Auto layout is somewhat complex, you need to master it while giving lot of time, but if you want to finish it in minutes, just uncheck the auto-layout, select every UI element and set its auto-resizing like this

You can change the auto-layout differently, and can see the changes by just tapping this button

Hope this will help and save time.

Very good question. I had ran into exactly same issues as you have with every single app of mine when I upgraded them to support iphone 5 screen size.

What I ended up doing was disable autolayout but I still use story board to place all my buttons, views, images etc. I make sure that I am using 3.5in in my storyboard while placing all the items. I then connect those UILabel or UIButton etc to an IBoutLet and then in my ViewDidLoad I check to see if its iphone 4 vs iPhone 5 and re position all the buttons accordingly.

for example.

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.

    if(UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone)
        {
            CGSize result = [[UIScreen mainScreen] bounds].size;
            if(result.height == 480)
            {
                // iPhone Classic

            }
            if(result.height == 568)
            {
                // iPhone 5 this is the offset I am using
                int yInt = 50;

                [blurSlider setFrame:CGRectMake(31, 406+yInt, 271, 34)];
                [alphaSlider setFrame:CGRectMake(31, 447+yInt, 271, 34)];

                [blurLabel setFrame:CGRectMake(33, 392+yInt, 71, 24)];
                [alphaLabel setFrame:CGRectMake(33, 436+yInt, 71, 24)];
            }
        }
}

Could I have done all the coding without ever using story board? of course I could have but I find the visual aspect of story board appealing and seeing exactly where everything fits on the screen.
