Split NSString multiple times on the same separator

Question

I am currently receiving a string like this:

@"Sam|26,Hannah|22,Adam|30,Carlie|32,Jan|54"

And I am splitting it like this:

testArray = [[NSArray alloc] init];
NSString *testString = [[NSString alloc] initWithFormat:@"Sam|26,Hannah|22,Adam|30,Carlie|32,Jan|54,Steve|56,Matty|24,Bill|30,Rob|30,Jason|33,Mark|22,Stuart|54,Kevin|30"];
testArray = [testString componentsSeparatedByString:@","];

dict = [NSMutableDictionary dictionary];
for (NSString *s in testArray) {

    testArray2 = [s componentsSeparatedByString:@"|"];
    [dict setObject:[testArray2 objectAtIndex:1] forKey:[testArray2 objectAtIndex:0]];
}

I will now be receiving a string like this:

@"Sam|26|Developer,Hannah|22|Team Leader,Adam|30|Director,Carlie|32|PA,Jan|54|Cleaner"

Can I (and how) use the same method as above to separate the string more than once using the "|" separator?

Answer 1

The following line...

testArray2 = [s componentsSeparatedByString:@"|"];

will cause the array to now contain 3 items, instead of 2..... no need to split again!

Answer 2

do like this.

NSString *testString = [[NSString alloc] initWithFormat:@"Sam|26,Hannah|22,Adam|30,Carlie|32,Jan|54,Steve|56,Matty|24,Bill|30,Rob|30,Jason|33,Mark|22,Stuart|54,Kevin|30"];
    NSArray *testArray = [testString componentsSeparatedByString:@","];
    NSLog(@"%@",testArray);
    for(int i=0;i<[testArray count];i++){
        NSString *str=[testArray objectAtIndex:i];
    NSArray *aa=[str componentsSeparatedByString:@"|"];
    NSLog(@"%@",aa);
    }

No need of retain the array.
