how can i write the code for iphone 3.5 inches screen and 4 inches screen for ios6 & ios7

Question

I am developing an app. In the app I wrote the code for a 3.5-inches screen and 4-inches screen for ios7&ios6. I took one view controller; in this view controller I want to display two images, one for the top and another for the bottom. On the ios7 3.5-inch screen and 4 inches screen there is no problem with the display. But on the ios6 screen for 4-inches screen and 3.5 inches screen, there is a display problem. The two images are not displayed properly. I don't know how to write the same code for both the ios6 and ios7 for 4-inches& 3.5 inches screen. Please give me ideas, anyone. I am new to programming. Thanks in advance.

The below is my code.

Viewcontroller.m (3.5 inches and 4-inches screen for ios7 & ios6).

if ([[UIScreen mainScreen] bounds].size.height == 568)
{
    imgLogo=[[UIImageView alloc]initWithFrame:CGRectMake(75, 65, 162, 57)];

    imgLogo.image=[UIImage imageNamed:@"Logo-01.png"];

    [self.view addSubview:imgLogo];

    imgBuilding=[[UIImageView alloc]initWithFrame:CGRectMake(8, 415, 300, 153 )];

    imgBuilding.image=[UIImage imageNamed:@"image-02.png"];

    imgBuilding.alpha=0.4;

    [self.view addSubview:imgBuilding];
}
else
{
    imgLogo=[[UIImageView alloc]initWithFrame:CGRectMake(75, 70, 162, 57)];

    imgLogo.image=[UIImage imageNamed:@"Logo-01.png"];

    [self.view addSubview:imgLogo];

    imgBuilding=[[UIImageView alloc]initWithFrame:CGRectMake(0, 345, 320,140 )];

    imgBuilding.image=[UIImage imageNamed:@"image-02.png"];

    imgBuilding.alpha=0.4;

    [self.view addSubview:imgBuilding];
}

You have to check whether os is IOS 7 or Earlier and depending upon that you have set your imageView.

    UIImageView *imgLogo;
    UIImageView *imgBuilding;
    if ([[UIScreen mainScreen] bounds].size.height == 568)
    {
        if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7)
        {
            imgLogo=[[UIImageView alloc]initWithFrame:CGRectMake(75, 65, 162, 57)];
            imgBuilding=[[UIImageView alloc]initWithFrame:CGRectMake(8, 415, 300, 153 )];
        }
        else
        {
            imgLogo=[[UIImageView alloc]initWithFrame:CGRectMake(75, 45, 162, 57)];
            imgBuilding=[[UIImageView alloc]initWithFrame:CGRectMake(8, 395, 300, 153 )];

        }
        imgLogo.image=[UIImage imageNamed:@"icon.png"];

        [self.view addSubview:imgLogo];
        imgBuilding.image=[UIImage imageNamed:@"icon.png"];

        imgBuilding.alpha=0.4;

        [self.view addSubview:imgBuilding];
    }
    else
    {
        if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7)
        {
            imgLogo=[[UIImageView alloc]initWithFrame:CGRectMake(75, 70, 162, 57)];
            imgBuilding=[[UIImageView alloc]initWithFrame:CGRectMake(0, 345, 320,140 )];
        }
        else
        {
            imgLogo=[[UIImageView alloc]initWithFrame:CGRectMake(75, 50, 162, 57)];
            imgBuilding=[[UIImageView alloc]initWithFrame:CGRectMake(0, 325, 320,140 )];
        }
        imgLogo.image=[UIImage imageNamed:@"icon.png"];

        [self.view addSubview:imgLogo];
        imgBuilding.image=[UIImage imageNamed:@"icon.png"];

        imgBuilding.alpha=0.4;

        [self.view addSubview:imgBuilding];
    }

You can do this via autoResizing aka 'Spring and Struts' or by utilizing the latest 'Autolayout' feature.
Either way allows you to maintain a single xib file while the positioning and sizing of the subViews remains the same (depending on the way you have set it up)

They can be set up via xib/storyboard as well as programmatically.

Springs and Struts was the previous method but it's still available:

Spring is the stretching ability of the subView
Strut is the placement or you can say, the hugging ability. (i.e. it hugs the top bound or the bottom bound or left or right)

Links:

Autolayout requires you to be comfortable with the concept of constraints
It's a tad bit more effort but hey, if apple says it's better, it sure is.

Links"

NOTE: You can't use both together. You have to disable Autolayout feature on the view if you want to use Springs & Struts

Can you provide some more details please? – Preet Sangha Nov 30 '13 at 08:05 — Preet Sangha, Nov 30 '13 at 08:05
