Model-View-Controller Design Pattern
*.h file: declare variables, define class
#import <UIKit/UIKit.h>
int count;
// global variable
Key word
@interface ViewController : UIViewController {
IBOutlet UILabel *number;
// variable
Subclass
Superclass
}
- (IBAction)add;
- (IBAction)subtract;
- (IBAction)reset;
- (IBAction)dbl;
- (IBAction)opposite;
@end
// method declaration
Method name
Return type
- : instance method
+: static method
Model-View-Controller Design Pattern
*.m file: implementation of class
Key word
@implementation ViewController
- (IBAction)add {
count++;
number.text = [NSString stringWithFormat:@"%i", count];
}
NSString object

“string” : C-style string

ence/Foundation/Classes/NSString_Class/Reference/NSString.html



The NSString class declares the programmatic interface for an object that manages
immutable strings. An immutable string is a text string that is defined when it is created
and subsequently cannot be changed. NSString is implemented to represent an array of
Unicode characters, in other words, a text string.
NSString class contains 146 methods.
stringWithFormat:
Returns a string created by using a given format string as a template into which the
remaining argument values are substituted.
+ (id)stringWithFormat:(NSString *)format, ...
UILabel Class Reference


The UILabel class implements a read-only text view. You can use
this class to draw one or multiple lines of static text, such as those
you might use to identify other parts of your user interface.
