Unable to convert comma separated string to an array

Question

I am using the following code to convert a comma separated string to an array.

NSString *domanIdStr = [Settings getSetting:@"selectedDomainId"];
NSLog(@"%@",domanIdStr);
NSArray *domainIds = [domanIdStr componentsSeparatedByString:@","];

NSLog(@"%@",domanIdStr); prints

(
    "1,2"
)

But then the third line componentsSeparatedByString throws the following error,

[__NSCFArray componentsSeparatedByString:]: unrecognized selector sent to instance 0x1702650c0

How can I be able to sort this out ?

Answer 1

NSLog(@"%@",domanIdStr); prints

(
    "1,2"
)

domanIdStr is not a string, it is an array. So, to properly get the domanIdStr, use this

NSArray * domanIdStr = [Settings getSetting:@"selectedDomainId"];
NSString *firstTag = domanIdStr[0]; //this would be "1"

or else if you want to extract then do like

 NSArray *domanIdStr = [Settings getSetting:@"selectedDomainId"];
 NSString *getString = domanIdStr[0];
NSArray *domainIds = [getString componentsSeparatedByString:@","];
NSLog(@"%@",domanIdStr[0]);
