Essential Objects and Their Commonly Used Methods
NSObject
  • - (id)init
NSObject *newNSObject = [[NSObject alloc] init];
  • - (NSString *)description
    • NSLog(@"Open Source Account Number: %d is %@", i, accountToPrint);

    is equivalent to

  • - (BOOL)isEqual:(id)that
    • // compares the logic written in the isEqual methods
if ([this isEqual:that]) { ... }

    may not be equivalent to 

    // compares the values of the two pointers
this == that;
    NSArray
    • - (NSUInteger)count
    NSArray *nsarray = [NSArray initWithObjects:@"Open Source!", nil];

NSUInteger *count;
count = [nsarray count];
  • - (id)objectAtIndex:(NSUInteger)index
    • NSArray *nsarray = [NSArray initWithObjects:@"Open Source!", nil];
