NSArray full of NSDictionaries. How to find the index of an object?

Question

I have an array that is populated with NSDictionaries . I want to find the index one of the dictionaries, but what I know about this dictionary is only the value for the key @"name". How can I do it?

Answer 1

Find the index of the first dictionary in theArray whose value for @"name" is equal to theValue :

 NSUInteger index = [theArray indexOfObjectPassingTest: ^BOOL(NSDictionary *dict, NSUInteger idx, BOOL *stop) { return [[dict objectForKey:@"name"] isEqual:theValue]; } ]; 

index will be NSNotFound if no matching object is found.

Answer 2

  NSArray *temp = [allList valueForKey:@"Name"]; NSInteger indexValue = [temp indexOfObject:YourText]; NSString *name = [[allList objectAtIndex:indexValue] valueForKey:@"Name"]
