Hey,
I´m a new developer in iphone´s world, develop in actionScript (flash OOP)
and build adGames and python too.
I always wanted to develop for mobile plataform, and now, with the iphone,
wich is a good gadget, I decided to join in new and long journey.
I´m studying objective-C around one month and have some doubts.
Follows the code with the doubts:
*Classe.h
*#import <UIKit/UIKit.h> //importa a classe UIKit
//constuctor of the class with type NSObject that extends a
UIApplicationDelegate, it is right?
@interface Classe : NSObject <UIApplicationDelegate> {
//variable type UIWindow (I think that create a screen application)
IBOutlet UIWindow *window;
//I don´t know what id IBOutlet
}
//I don't understand this line
@property (nonatomic, retain) UIWindow *window;
@end
*Classe.m*
//importa o header (que seria o contructor da classe certo?)
//import the header (is that a constructor of the class?)
#import "teste2AppDelegate.h"
//implement the interface in content
@implementation teste2AppDelegate;
//instance window in content?
@synthesize window;
//metodo chamado quando o aplicativo é executado e não retorna nada(void),
ele recebe como parâmetro um UIApplicaton (pq?)
//metod called when the application run, don´t return nothing(void), recives
one parameter UIApplicaton
- (void)applicationDidFinishLaunching:(UIApplication *)application {
//create a textField
//Is it the same that "var _txt:UITextField = new UITextField()" ???
UITextField *_txt = [[UITextField alloc] init];
[_txt setTextColor:[UIColor redColor]]; //set color in red color, this color
return from UIColor class
[_txt setText:@"teste"]; //set text
}
//Why do is metod ?
- (void)dealloc {
[window release];
[super dealloc];
}
@end
In my journey I understand that execute one function I use
[nameFunction:param1, p:param2. Pp:param3], right?
When compiling this script don't show error and open iPhone emulator, but
show a whit screen and not show the text.
Ok, any help will be good help.
Thanks…
