iOS学习笔记12—新浪微博分享

一.申请开发者账号，创建应用

在http://open.t.sina.com.cn / 中申请成为开发者，再创建不同的应用，获得相应的 App
Key  （在下面链接中的source即为app
key）保存好好自己的

kAppKey   kAppSecret  kAppRedirectURI 

二.调用

1.下载官方的SDK解压 并将需要的文件拖到你的工程里面  需要导入的类库现在忘记了 大家应该可以能找到的吧



创建好分享界面



在Appdelegate.h中添加

#import <UIKit/UIKit.h>
#import "SinaWeibo.h"

#import "SinaWeiboRequest.h"
#import "FenXiangViewController.h"
//加入你申请的东西
#define kAppKey             @"******"
#define kAppSecret          @"*****"
#define kAppRedirectURI     @"*****"

#ifndef kAppKey
#error
#endif

#ifndef kAppSecret
#error
#endif

#ifndef kAppRedirectURI
#error
#endif

//#import "LogeViewController.h"
@class SinaWeibo;
@class RootViewController;
@class LogeViewController;
@interface AppDelegate : UIResponder <UIApplicationDelegate,SinaWeiboDelegate,SinaWeiboRequestDelegate>

{
SinaWeibo *_sinaWeibo;

FenXiangViewController *_viewController;

}
@property (strong, nonatomic) UIWindow *window;

@property (strong, nonatomic) FenXiangViewController *fenxiangviewController;
@property (readonly, nonatomic) SinaWeibo *sinaWeibo;

@end

在AppDelegate.m中添加

#import "AppDelegate.h"
#import "RootViewController.h"
#import "SinaWeibo.h"

@implementation AppDelegate
@synthesize sinaWeibo = _sinaWeibo;
@synthesize window = _window;
@synthesize fenxiangviewController = _fenxiangviewController;

- (void)dealloc
{
[_sinaWeibo release];
[_viewController release];
[_window release];

[super dealloc];
}

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
self.window.backgroundColor = [UIColor whiteColor];
[self.window makeKeyAndVisible];
self.window.backgroundColor = [UIColor whiteColor];

//先初始化视图然后在把微博的delegate给视图
_fenxiangviewController =[[FenXiangViewController alloc]init];

_sinaWeibo = [[SinaWeibo alloc] initWithAppKey:kAppKey appSecret:kAppSecret appRedirectURI:kAppRedirectURI andDelegate:_fenxiangviewController];
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
NSDictionary *sinaweiboInfo = [defaults objectForKey:@"SinaWeiboAuthData"];
if ([sinaweiboInfo objectForKey:@"AccessTokenKey"] && [sinaweiboInfo objectForKey:@"ExpirationDateKey"] && [sinaweiboInfo objectForKey:@"UserIDKey"])
{
_sinaWeibo.accessToken = [sinaweiboInfo objectForKey:@"AccessTokenKey"];
_sinaWeibo.expirationDate = [sinaweiboInfo objectForKey:@"ExpirationDateKey"];
_sinaWeibo.userID = [sinaweiboInfo objectForKey:@"UserIDKey"];
}

}

- (void)applicationDidBecomeActive:(UIApplication *)application
{
[self.sinaWeibo applicationDidBecomeActive];
}

- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url
{
return [self.sinaWeibo handleOpenURL:url];
}

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation
{
return [self.sinaWeibo handleOpenURL:url];
}

则在分享界面.h文件中

#import <UIKit/UIKit.h>
#import "SinaWeibo.h"

#import "SinaWeiboRequest.h"

@class SinaWeibo;
@class RootViewController;
@class FenxiangViewController;

NSString *postImageStatusText;

UIActivityIndicatorView *activity;
}

最后需要在Supporting Files 里面的.plist配置文件里面加载



然后点击测试你的程序吧
