Question

I have a string coming from database in a format like

“2,5,5,3”

.
What i am trying to do is, i want to separate every int from this string and assign in a new variable.
Than, on the basis if it i want to show images.
For ex:
i have 5 image views named as

img1,img2,img3 etc

so if i get output from db as “3,2,4 “

than i want to show img3, img2 and img4.
So my images depends on the returned string.
How can i move forward in order to implement it.

Answer 1

Use like this

img1.hidden=YES;
img2.hidden=YES;
img3.hidden=YES;
img4.hidden=YES;
img5.hidden=YES;
NSArray *array = [yourString componentsSeparatedByString:@","];

for (NSString* aNumber in array)
{
   NSInteger i=[aNumber intValue];

  switch(i)
  {

        case 1:
            img1.hidden=NO;
            break;
        case 2:
            img2.hidden=NO;
            break;
        case 3:
            img3.hidden=NO;
            break;
        case 4:
            img4.hidden=NO;
            break;
        case 5:
            img5.hidden=NO;
            break;
  }

}
