iOS应用程序自动调整内容大小以适合不同的屏幕尺寸

Question

I'm going to implement an ios application design. The design is made with iphone 5 screen size in mind (640 x 1136 px).

I want to automatically resize all the content to fit screen size of the display it will be running on, including: font size, bitmap size, subview size.

Ideally I want to code only once that assume the width of the device is 320 points regardless the actual width of the device. Iphone 6 and 6s have bigger displays but still have the same aspect ratio.

For example if I create a box of UIView in my viewcontroller:

UIView *box = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 10)];
box.backgroundColor = [UIColor redColor];
[self.view addSubView:box];

will always draw a red box spanning full width of the screen regardless device screen size (in iphone 6 & 6s). I do most of the visual component and layouting using code like above including for creating UILabel, etc.

Basically it is functioning like 'display zoom' feature in iphone 6, 6plus, but only for this application. (not globally)

What trick to do to get the desired result ? If possible I don't want to use autolayout.

Thanks,

@night_coder, i am not sure about what ur trying to say, but based up on my understand i am answering you.

You can go for Visual Layouts (If you trying programatically)

or

you can go Auto Resizing, by disabling auto layouts and subviews (If you trying threw story board)
