Convert NSString separated by comma to NSArray [duplicate]

Convert NSArray to NSString in Objective-C

I have an array of an NSArray myArray, here is the content:

 (
            "<MPConcreteMediaItem: 0x1b7dd0> 8671085923283003246",
            "<MPConcreteMediaItem: 0x1b7e50> 16275751483823231324",
            "<MPConcreteMediaItem: 0x1b7e70> 4976771456698615367"
 )

I used the code below to assign to an NSString myString:

NSString *myString = [myArray description];

And the out put is still as expected:

 (
            "<MPConcreteMediaItem: 0x1b7dd0> 8671085923283003246",
            "<MPConcreteMediaItem: 0x1b7e50> 16275751483823231324",
            "<MPConcreteMediaItem: 0x1b7e70> 4976771456698615367"
 )

Now, say I want to convert myString back to an array named newArray, I used this:

NSArray *newArray = [[NSArray alloc]init];
newArray = [myString componentsSeparatedByString:@","];

But the content of the newArray is now different:

(       
"(
    \"<MPConcreteMediaItem: 0x1b7dd0> 8671085923283003246\"",
        "
    \"<MPConcreteMediaItem: 0x1b7e50> 16275751483823231324\"",
        "
    \"<MPConcreteMediaItem: 0x1b7e70> 4976771456698615367\""
)"
) 

Any idea what I need to do to fix this?

There are two methods

  • - (NSArray *)componentsSeparatedByString:(NSString *)separator
  • - (NSString *)componentsJoinedByString:(NSString *)separator

Use

NSString *myString = [myArray componentsJoinedByString:@","]; //instead of [myArray description];
