Finding maximum numeric value in NSArray

Question

I have an NSArray of NSNumbers and want to find the maximum value in the array. Is there any built in functionality for doing so? I am using iOS4 GM if that makes any differ

Answer 1

NSArray *  test= @[@3, @67, @23, @67, @67];
int maximumValue = [[test valueForKeyPath: @"@max.self"] intValue];
 NSLog(@" MaximumValue = %d", maximumValue);

// Maximum = 67
