Using fgets to read from the keyboard
Getting numbers from strings
• Once we've got a string with a number in it (either from a file or from the user typing) we can use atoi or atof to convert it to a number • The functions are part of stdlib.h
File handling in C
• In C we use FILE * to represent a pointer to a file. • fopen is used to open a file. It returns the special value NULL to indicate that it couldn't open the file.
FILE *fptr; char readfname[1000]; fgets (readfname,1000,stdin); fptr= fopen (readfname,"w"); /* oopsie - file name also has \n */
Even experienced programmers can make this error
char numberstring[]= "3.14"; int i; double pi; pi= atof (numberstring); i= atoi ("12"); Both of these functions return 0 if they have a problem

Review: Methods, Selectors, Messages
Selector
Name for referring to a method ! Includes colons to indicate arguments ! Doesn't actually include arguments or indicate types
Two step process
allocate memory to store the object ! initialize object state
!
+ alloc
!
Class method that knows how much memory is needed Instance method to set initial values, perform other setup
Memory Management
Allocation C Objective-C
malloc alloc
Destruction
free dealloc
Calls must be balanced
!
Otherwise your program may leak or crash One exception, we'll see in a bit...
!
Review: Methods, Selectors, Messages
Method
!
Behavior associated with an object
- (NSString *)name { // Implementation } - (void)setName:(NSString *)name { // Implementation }
200-205, 3:15 - 4:05 PM ! Debugging crash course, not to be missed!
!
Class newsgroup (Stanford-only) at su.class.cs193p
!
No gopher site yet...
Today's Topics
!
Person NSObject (in this case) Name, age, whether they can vote Cast a ballot
Determine the superclass
!
What properties should it have?
!
What actions can it perform?
Questions from Assignment 1A or 1B? Creating Custom Classes Object Lifecycle Autorelease Objective-C Properties
Custom Classes
Design Phase
Create a class
Defining a class
A public header and a private implementation
Header File
Implementation File
Implementing custom class
Implement setter/getter methods Implement action methods
Calling your own methods
#import "Person.h" @implementation Person - (BOOL)canLegallyVote { return ([self age] >= 18); } - (void)castBallot { if ([self canLegallyVote]) { ! ! // do voting stuff } else { ! ! NSLog (@"I'm not allowed to vote!"); } } @end
Finishing Up With an Object
Person *person = nil; person = [[Person alloc] init]; [person setName:@"Alan Cannistraro"]; [person setAge:29]; [person setWishfulThinking:YES]; [person castBallot]; // What do we do with person when we're done?
Superclass methods
As we just saw, objects have an implicit variable named "self"
!
Like "this" in Java and C++
- (void)doSomething { // Call superclass implementation first [super doSomething]; // Then do our custom behavior int foo = bar; // ... }
Class Implementation
#import "Person.h" @implementation Person - (int)age { return age; } - (void)setAge:(int)value { age = value; } //... and other methods @end
Can also invoke superclass methods using "super"
Object Lifecycle
Object Lifecycle
Creating objects Memory management Destroying objects
Object Creation
Less specific ones typically call more specific with default values
- (id)init { return [self initWithName:@"No Name"]; } - (id)initWithName:(NSString *)name { return [self initWithName:name age:0]; }
Enrolled Stanford students can email cs193p@ with any questions ! Submit early! Instructions on the website...
!
!
Delete the "build" directory manually, Xcode won't do it
-dealloc method invoked automatically
However, you'll never call -dealloc directly
!
Reference Counting
Every object has a retain count
Defined on NSObject ! As long as retain count is > 0, object is alive and valid
Defining a class
A public header and a private implementation
Header File
Implementation File
Class file
#import <Foundation/Foundation.h> @interface Person : NSObject { // instance variables NSString *name; int age; } // method declarations - (NSString *)name; - (void)setName:(NSString *)value; - (int)age; - (void)setAge:(int)age; - (BOOL)canLegallyVote; - (void)castBallot; @end
}
} @end
return self;
Multiple init methods
Classes may define multiple init methods
- (id)init; - (id)initWithName:(NSString *)name; - (id)initWithName:(NSString *)name age:(int)age;
Message
The act of performing a selector on an object ! With arguments, if necessary
!
NSString *name = [myPerson name]; [myPerson setName:@"New Name"];
- init
!
Create = Allocate + Initialize
Person *person = nil; person = [[Person alloc] init];
Implementing your own -init method
#import "Person.h" @implementation Person - (id)init { // allow superclass to initialize its state first if (self = [super init]) { age = 0; name = @"Bob"; // do other initialization...
