See the "Set and Ar
You can use key-path collection operators, assuming someTrips is a property of
self:
NSNumber *minPrice = [self
valueForKeyPath:@"sometri...@min.adultfinalprice"];
NSNumber *maxPrice = [self
valueForKeyPath:@"sometri...@max.adultfinalprice"];
By the way, minValue and maxValue in your e
Yes, as already suggested by Preston, key path operators are very expressive.
Thanks for the suggestions.

You could get even less, more expressive code, using key path operators:
NSNumber *minValue = [someTrips

Hi,
I want to use blocks to extract the min price and the max price from
an NSArray of trips. I've found the following way:
float minValue = 0.0;
[someTrips enumerateObjectsUsingBlock:^(id obj, NSUInteger idx,
BOOL *stop) {
if (minValue == 0.0 || [[obj adultFinalPrice] floatValue] <
