iOS 微博 OAuth2.0 分享文字微博的方法

这里以新浪的为例子进行说明，后面会陆续添加；

这里同时提供两种方式，一种是通过ASIFormData的方式来完成

NSURL *url = [[NSURLalloc] initWithString:@"https://api.weibo.com/2/statuses/update.json"];

// statuses/upload

ASIFormDataRequest *request = [[ASIFormDataRequestalloc] initWithURL:url];

NSUserDefaults *info = [NSUserDefaultsstandardUserDefaults];

[request addPostValue:SINAAPPKEY forKey:@"source"];

[request addPostValue:Text forKey:@"status"];

[request addPostValue:@"0" forKey:@"lat"];

[request addPostValue:@"0" forKey:@"long"];

[request addPostValue:[selfDecrypt:MyPWDKey :[info objectForKey:@"sina_access_tokenV2"]] forKey:@"access_token"];

[request startSynchronous];

NSString *rst = [request responseString];

[request release];

[url release];

另一个种是通过iOS SDK 来实现

NSAutoreleasePool *pool = [[NSAutoreleasePoolalloc] init];

NSUserDefaults *info = [NSUserDefaultsstandardUserDefaults];

NSString *post=[NSStringstringWithFormat:@"source=%@&status=%@&lat=0&long=0&access_token=%@",SINAAPPKEY,sinaWeiBoText,[selfDecrypt:MyPWDKey :[info objectForKey:@"sina_access_tokenV2"]]];

NSData *postData=[post dataUsingEncoding:NSUTF8StringEncodingallowLossyConversion:YES];

NSString *postLength=[NSString stringWithFormat:@"%d",[postData length]];

NSMutableURLRequest *request=[[NSMutableURLRequestalloc] initWithURL:[NSURLURLWithString:SINASENDTEXT]];

[request setHTTPMethod:@"POST"];

[request setValue:postLength forHTTPHeaderField:@"Content-Length"];

[request setValue:@"application/x-www-form-urlencoded"forHTTPHeaderField:@"Content-Type"];

[request setHTTPBody:postData];

NSURLConnection *conn = [[NSURLConnection alloc] initWithRequest:request delegate:self];

if (conn)

{

NSURLResponse *response;

NSError *error;

NSData *resutlData=[NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];

NSString *resultSting=[[NSStringalloc] initWithData:resutlData encoding:NSUTF8StringEncoding];

NSDictionary *dict = [[NSDictionary alloc] initWithDictionary:[resultSting JSONValue]];

NSLog(@"%@",dict);

if ([dict objectForKey:@"error_code"] != nil) {

int code = [[dict objectForKey:@"error_code"] intValue];

NSLog(@"code = %d",code);

if (code == 20019) {

[self showMessage:@"不能发布相同的微博!"];

}

else {

[self showMessage:@"发送微博失败!"];

}

}

else {

[self showMessage:@"分享新浪微博成功!"];

}

[resultSting release];

[dict release];

}

[conn release];

[request release];

[pool release];

第一种方式更为简洁
