objective c - Dont work objectsWithPredicate with operator "NOT IN"? -


i need take items array not in database.i'm trying make predicate

nspredicate *predicate = [nspredicate predicatewithformat:@"!(id in %@)", ids];  return[productmodel objectswithpredicate:predicate];

but returns nil, if use predicate without not, works. work in coredata - predicate returns objects not in database. doesn`t work in realm.

try 

nspredicate *predicate = [nspredicate predicatewithformat:@"not (id in %@)", ids];  nsarray *filtered  = [ids filteredarrayusingpredicate:predicate];

Unlimited choices in BASH case statement -

consider simple bash snippet: case $option in 1) image=${options[0]%.tar} ;; 2) image=${options[1]%.tar} ;; 3) image=${options[2]%.tar} ;; 4) image=${options[3]%.tar} ;; *) echo "invalid option" exit 1 esac in real script numbers goes 30. makes pretty long. can somehow specify cases variable? something this: case $option in $i) image=${options[$(($i-1))]%.tar} any pointer appreciated. you can match against multiple patterns in single clause: case $option in 1|2|3: echo "$option one, 2 or three" ;; esac if still typing you, can use simple pattern matching: case $option in # following matches # - single-digit numbers 0-9 # - two-digit numbers starting either 1 or 2 # - number 30 [0-9]|[12][0-9]|30) image=${options[$(($option-1))]%.tar} ;; *) echo "invalid option" 1>&2 exit 1 esac
