iPhone 開發教學 發訊息到 Facebook 塗鴉牆 用 Facebook Connect 架構
How To: Implement Facebook Connect on the iPhone in 5 minutes from Cat Lee on Vimeo.若想要開發一些 iPhone 小軟體，並將一些訊息發佈到 Facebook 上面，可以先逛逛這些頁面：
Mobile - Facebook Developer Wiki Facebook Connect for iPhone - Facebook Developer Wiki Facebook Connect - Facebook Developer Wiki [*]iPhone FBConnect: Facebook Connect Tutorial
剩下的就仿造 Facebook Connect for iPhone - Facebook Developer Wiki 所提到的設定，先到 facebook's facebook-iphone-sdk at master - GitHub 下載相關程式碼，可在右邊直接按 Download Source 下載。http://farm3.static.flickr.com/2697/4453745186_13e285ee2f.jpg以下參考 iPhone 開發教學 - 環境設置和第一支程式 Hello World 範例，建立一個簡單的範例後，接著去打開下載回來的檔案，此例為 facebook-facebook-iphone-sdk-5382dcd.zip ，並且解開後找其子目錄 src 中，點選開啟 FBConnect.xcodeproj ，接著將 FBConnect 拖拉到 HelloWorld 上頭，並且使用預設選項不勾選 copy items 囉http://farm5.static.flickr.com/4024/4453745250_a6faa08d9c.jpg接著，設定 HelloWorld 這個專案，->->->->-> 點選右邊空白，增加你下載的 facebook-iphone-sdk 程式碼的位置，在此使用 /Users/uid/Downloads/facebook-facebook-iphone-sdk-5382dcd/src，弄完接著就可以對 HelloWorld 進行編譯看看，->-> ，在此只看到一個 warning ，先暫時不管他。
開始正式測試 Facebook 與 iPhone 的結合啦
原樣：
HelloWorldAppDelegate.h
#import <UIKit/UIKit.h>
@interface HelloWorldAppDelegate : NSObject <UIApplicationDelegate> {
UIWindow *window;
IBOutlet UILabel *showLabel;
IBOutlet UIButton *actionButton;
}
@property (nonatomic, retain) IBOutlet UIWindow *window;
- (IBAction)updateLabel;
@end
HelloWorldAppDelegate.m
#import "HelloWorldAppDelegate.h"
@implementation HelloWorldAppDelegate
@synthesize window;
- (void)applicationDidFinishLaunching:(UIApplication *)application {
// Override point for customization after application launch
;
}
- (void)awakeFromNib {
showLabel.text = @"Hello World!";
}
- (IBAction)updateLabel {
static int count = 0;
showLabel.text = ;
}
- (void)dealloc {
;
;
}
@end
更改後：
HelloWorldAppDelegate.h
#import <UIKit/UIKit.h>
#import "FBConnect/FBConnect.h"
#import "FBConnect/FBSession.h"
#define FB_APP_KEY @"YOUR_APP_KEY"
#define FB_SEC_KEY @"YOU_SEC_KEY"
@interface HelloWorldAppDelegate : NSObject <UIApplicationDelegate>{
UIWindow *window;
IBOutlet UILabel *showLabel;
IBOutlet UIButton *actionButton;
IBOutlet FBLoginButton *fbButton;
FBSession *fbSession;
id<FBRequestDelegate> delegate;
int status;
}
@property (nonatomic, retain) IBOutlet UIWindow *window;
@property (nonatomic, retain) IBOutlet FBLoginButton *fbButton;
@property (nonatomic, retain) FBSession *fbSession;
@property(nonatomic,assign) id<FBRequestDelegate> delegate;
- (IBAction)updateLabel;
@end
HelloWorldAppDelegate.m
#import "HelloWorldAppDelegate.h"
@implementation HelloWorldAppDelegate
@synthesize window;
@synthesize fbButton;
@synthesize fbSession;
@synthesize delegate;
- (void)applicationDidFinishLaunching:(UIApplication *)application {
status = 0 ;
// Override point for customization after application launch
;
}
- (void)awakeFromNib {
showLabel.text = @"Hello World!";
if ( self.fbSession == nil ) {
self.fbSession = ;
}
}
- (void)session:(FBSession*)session didLogin:(FBUID)uid {
status = 1;
NSString* fql = ;
NSDictionary* params = ;
[ call:@"facebook.fql.query" params:params];
}
- (void)request:(FBRequest*)request didLoad:(id)result {
if () {
NSString * username = [ ((NSDictionary*)[(NSArray*)result objectAtIndex:0 ]) objectForKey:@"name"] ;
showLabel.text = ;
}
}
- (IBAction)updateLabel {
if ( status == 0 ) { // do login
FBLoginDialog* dialog = [[ initWithSession:self.fbSession] autorelease];
;
}
else { // do post to Wall
FBStreamDialog* dialog = [[ init] autorelease];
dialog.delegate = self;
dialog.userMessagePrompt = @"Example prompt";
dialog.attachment = @
"{"
"\"name\":\"Facebook Connect for iPhone\","
"\"href\":\"http://developers.facebook.com/connect.php?tab=iphone\","
"\"caption\":\"Caption\","
"\"description\":\"Description\","
"\"media\":[{"
"\"type\":\"image\","
"\"src\":\"http://img40.yfrog.com/img40/5914/iphoneconnectbtn.jpg\","
"\"href\":\"http://developers.facebook.com/connect.php?tab=iphone/\"}],"
"\"properties\":{"
"\"another link\":{"
"\"text\":\"Facebook home page\","
"\"href\":\"http://www.facebook.com\""
"}"
"}"
"}";
// dialog.targetId = @"999999"; // replace this with a friend's UID
;
}
}
- (void)dealloc {
;
;
;
;
}
@end
一開始
http://farm3.static.flickr.com/2800/4452967555_5c0e9291e9.jpg按下按鈕，進入登入畫面
http://farm3.static.flickr.com/2796/4453745380_da50868755.jpg登入後，顯示暱稱
http://farm3.static.flickr.com/2774/4452967685_0be0d4a6b7.jpg按下按鈕，進入發佈到塗鴉牆的過程
http://farm5.static.flickr.com/4022/4452967789_73869d263c.jpg輸入資料中
http://farm5.static.flickr.com/4015/4453745632_31b732aaca.jpg在 Facebook 上的顯示
http://farm3.static.flickr.com/2791/4453745658_cc946ced86_o.png程式解說：
透過 status 變數控制，當 status ==0 時按下 button 時，歸類在做 login 的動作，等到登入成功後，則 status 更新為 1 ，當 status == 1 時，按下 button 後，則進入發佈到塗鴉牆的動作。目前程式有點類似拼湊起來的，編譯上會有 warning： Class 'HelloWorldAppDelegate' does not implement the 'FBSesionDelegate' protocol
Class 'HelloWorldAppDelegate' does not implement the 'FBRequestDelegate' protocol
Class 'HelloWorldAppDelegate' does not implement the 'FBDialogDelegate' protocol 建議可以看看 iPhone FBConnect: Facebook Connect Tutorial 所規劃的程式範例，上頭有作架構上的切割，在此只是純粹測試 Facebook API ，除了全部擠在一起外，還有些函數寫的不謹慎，只是恰好此情況不會出現什麼問題囉！ {:5_6:}人在做天在看，推到天上......
知道了 ~~~
