String Conversion between NSString and C strings

NSString *nsstr;
const char *cstr = "Open Source!";

// Convert a C string to a NSString
nsstr = [NSString stringWithUTF8String:cstr];

// Convert a NSString to a C string
cstr  = [nsstr UTF8String];

Automatically Called Methods

• (void)awakeFromNib

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

NSLog(@"Open Source Account Number: %d is %@", i, [accountToPrint description]);

• - (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];

NSObject *nsobject = [nsarray objectAtIndex:0];

• - (id)lastObject

NSArray *nsarray = [NSArray initWithObjects:@"Open Source!", nil];

NSObject *nsobject = [nsarray lastObject];

• - (BOOL)containsObject:(id)that

if ([this containsObject:that]) { ... }

• - (NSUInteger)indexOfObject:(id)that

NSArray *nsarray = [NSArray initWithObjects:@"Open Source!", nil];

NSUInteger *index;
index = [nsarray indexOfObject:@"Open Source!"];

NSMutableArray

• - (void)addObject:(id)that

NSMutableArray *nsmarray = [NSMutableArray initWithObjects:@"Open Source!", nil];

[nsmarray addObject:@"Open Mind!"];

• - (void)addObjectFromArray:(NSArray *)that

NSMutableArray *nmsarray = [NSMutableArray initWithObjects:@"Open Source!", nil];
NSArray *nsarray = [NSArray initWithObjects:@"Open Mind!", nil];

[nsmarray addObjectFromArray:nsarray];

• - (void)insertObject:(id)that atIndex:(NSUInteger)index

NSMutableArray *nsmarray = [NSMutableArray initWithObjects:@"Open Source!", nil];

[nsmarray insertObject:@"Open Mind!" atIndex:1];

• - (void)removeAllObjects

NSMutableArray *nsmarray = [NSMutableArray initWithObjects:@"Open Source!", nil];
[nsmarray addObject:@"Open Mind!"];

[nsmarray removeAllObjects];

• - (void)removeObject:(id)that

NSMutableArray *nsmarray = [NSMutableArray initWithObjects:@"Open Source!", nil];
[nsmarray addObject:@"Open Mind!"];

[nsamrray removeObject:@"Open Source!"];

• - (void)removeObjectAtIndex:(NSUInteger)index

NSMutableArray *nsmarray = [NSMutableArray initWithObjects:@"Open Source!", nil];
[nsmarray addObject:@"Open Mind!"];

[nsmarray removeObjectAtIndex:0];

NSString

• - (id)initWithFormat:(NSString *)format, ...

NSString *nsstring = [NSString initWithFormat:@"Open %@!", @"Source"];

• - (NSUInteger)length
