Turn multiple values from NSCollectionView into one NSString

Question

This checks my collection view if there is something called "BETA". When this is the case, it should look what the itemID of it is. This should be brought together and return something like "2 4" in a plist file.

In my log I get "Teststring 2" and "Teststring 4" but what I need is that it logs "Teststring 2 4". So it needs to bring those two values together.

  self.content = [NSMutableArray arrayWithObjects:
                      @{@"itemTitle":@"Passave",
                        @"itemVersion":@"1.2.0.1",

                    nil];

The Code:

if ([[self.representedObject valueForKey:@"itemPrice"] isEqualToString:@"BETA"]) {
            NSLog(@"BETA YES ID : %@", [self.representedObject valueForKey:@"itemID"]);

            NSMutableString *teststring = [[NSMutableString alloc]init];
            [teststring appendString:[self.representedObject valueForKey:@"itemID"]];
            NSLog(@"Teststring %@", teststring);
            [Functions saveDataToPlist:plistPathSMSettings OfType:@"String" Value:teststring ForKey:betaDef];
        }

what's your question? If you put the above code in loop and change self.representedObject to an iterator, you will find all your 'BETA' cases. — john elemans, Jun 27 '16 at 21:28
Oh, I see. You need to create your string 'teststring' outside of the search loop. Then just append hits onto it inside the loop. — john elemans, Jun 27 '16 at 21:38
oh ok thanks, how can i get that string out of any code? Should i first write it onto the .h file? — Damian Van de Kauter, Jun 27 '16 at 22:06
you can write it to a file if you need to save it between different uses of the application. Otherwise why do you need to save it? — john elemans, Jun 27 '16 at 22:18
it still doesn't work, i have added an NSMutableString to the .h file and the I say to append the MutableString to the newstring, but it still is not good. Look at the answer i have given below. — Damian Van de Kauter, Jun 27 '16 at 22:38
It doesn't matter where to declare it, but where to alloc it. You have create it outside of the search loop. — john elemans, Jun 27 '16 at 22:39

.h file

NSMutableString *teststring;

.m file

teststring = [[NSMutableString alloc]init];
NSLog(@"Teststring 1: %@", teststring);

NSString* LibraryPath = [NSSearchPathForDirectoriesInDomains(NSLibraryDirectory, NSUserDomainMask, YES) objectAtIndex:0];
NSString *plistPathSMSettings = [LibraryPath stringByAppendingString:stormarManagerSettingsPlistPath];

NSString *betaKeyDef = [SMSettingsDEF stringByAppendingString:@"BETA's"];
NSString *betaDef = [SMInAppCommunicationDEF stringByAppendingString:@"BETA App Id"];

NSString *isBeta = [Functions readDataFromPlist:plistPathSMSettings ForKey:betaKeyDef];

if ([isBeta isEqualToString:@"YES"]) {
    [Functions saveDataToPlist:plistPathSMSettings OfType:@"String" Value:@"" ForKey:betaDef];
}
else if ([isBeta isEqualToString:@"NO"]) {
    if ([[self.representedObject valueForKey:@"itemPrice"] isEqualToString:@"BETA"]) {
        NSLog(@"BETA YES ID : %@", [self.representedObject valueForKey:@"itemID"]);
        NSLog(@"Teststring 2: %@", teststring);
        NSString *theString = [teststring stringByAppendingString:[self.representedObject valueForKey:@"itemID"]];
        NSLog(@"Teststring 2 1: %@", theString);
        [teststring appendString:theString];
        NSLog(@"Teststring 3: %@", teststring);
        //[Functions saveDataToPlist:plistPathSMSettings OfType:@"String" Value:teststring ForKey:betaDef];
    }
}
