NSInteger counts times 4?

Question

I don't understand why this NSInteger counter increments to exactly 4 times the true value of database rows. Maybe this is stupid but I really just don't get it...

Thanks so far :)

NSInteger *i;
i = 0;

for ( NSDictionary *teil in gText ) {

    //NSLog(@"%@", [teil valueForKey:@"Inhalt"]);

    [databaseWrapper addEntry:[teil valueForKey:@"Inhalt"] withTyp:[teil valueForKey:@"Typ"] withParagraph:[teil valueForKey:@"Paragraph"]];

    i+=1;
}

NSLog(@"Number of rows created: %d", i);

Answer 1

Because i is a pointer and you are incrementing the pointer value which will most likely be in steps of 4 (size of NSInteger pointer). Just remove the pointer * reference and you should be good.

NSInteger i = 0;

for ( NSDictionary *teil in gText ) {

In theory you COULD do this the hard way.

NSInteger *i;
*i = 0;
for ( NSDictionary *teil in gText ) {
...
*i = *i + 1;
...
