How to read values from NSArray of NSDictionaries - iphone

Question

I have an array of NSDictionary values that looks like this when NSLogged
{
HASMOD = F;
ISLOCKED = F;
ISREGD = F;
MANU = "HORNET";
ID = 706;
},
{
HASMOD = T;
ISLOCKED = F;
ISREGD = T;
MANU = "BANJI";
ID = 225;
},
//etc
I am trying to save these values to my core data object (with correct types). I have been following this tutorial and have reached the point where I am trying to insert the values into each of the objects, However I am not sure how to do this from an array of dictionaries.. as it only shows how to enter one lot of information
So I have attempted doing it myself.. but its more pseudo code than anything... this is as far I have as I done... hopefully it helps make sense of what I am trying to achieve.
// WRITE TO CORE DATA
NSManagedObjectContext *context = [self managedObjectContext];
Manuf *manuf = [NSEntityDescription insertNewObjectForEntityForName:#"Manuf" inManagedObjectContext:context];
int mycount = [parsedDataArrayOfDictionaries count];
while (mycount != 0) {
// Somehow read Dictionaries and put them into their correct value types
BOOL hasModBool;
hasModelBool =
BOOL isLockedBool;
isLockedBool =
BOOL isRegedBool;
isRegedBool =
NSString *manuString = [[NSString alloc] init];
manuString =
int manuIDInt;
manuIDInt =
// pass all the values into the manuf coredata obj
manuf.hasMod = hasModBool;
manuf.isLocked = isLockedBool;
manuf.isReged = isRegedBool;
manuf.manu = manuString;
manuf.manuID = manuIDInt;
count --; // itterate through the array
}
I am hoping someone can help me run through the array of dictionaries and insert them into the variables of my core data object..
any help would be greatly appreciated.

Just use a for-in loop to iterate through your array, and get the values with valueForKey:.
for (NSDictionary *dict in parsedDataArrayOfDictionaries) {
Manuf *manuf = [NSEntityDescription insertNewObjectForEntityForName:#"Manuf" inManagedObjectContext:context];
BOOL hasModelBool;
BOOL isLockedBool;
BOOL isRegedBool;
if([dict valueForKey:#"HASMOD"] isEqualToString:#"T"]) {
hasModelBool = TRUE;
}else{
hasModelBool = FALSE;
if([dict valueForKey:#"ISLOCKED"] isEqualToString:#"T"]) {
isLockedBool = TRUE;
}else{
isLockedBool = FALSE;
......
......
// pass all the values into the manuf coredata obj
manuf.hasMod = hasModBool;
manuf.isLocked = isLockedBool;
manuf.isReged = isRegedBool;
manuf.manu = manuString;
manuf.manuID = manuIDInt;
}
I'm assuming here that the "T" or "F" values in your dictionaries are strings that need to be converted to TRUE or FALSE.
