I have NSNumber * year
property of NSManagedObject
, it's type in data model is Integer 16
.
I try to check with NSPredicate
for this year, but can't find the right one.
What I tried:
NSPredicate *p = nil;
NSNumberFormatter *nf = [[NSNumberFormatter alloc] init];
NSNumber *yearNo = [nf numberFromString:term];
if (yearNo) {
p = [NSPredicate predicateWithFormat:@"(cars.year == %i)", yearNo.intValue];
}
I also tried:
NSPredicate *p = nil;
NSNumberFormatter *nf = [[NSNumberFormatter alloc] init];
NSNumber *yearNo = [nf numberFromString:term];
if (yearNo) {
p = [NSPredicate predicateWithFormat:@"(cars.year == %@)", yearNo];
}
In both cases app crashes.
If you provide more details for your model, we could help you.
But I think the problem is due to cars
. If cars
is to-many you need a modifier for this
[NSPredicate predicateWithFormat:@"ANY cars.year == %@", yearNo];
