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

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];
    }

Hope this will help you.

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.

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