小编Sat*_*ish的帖子

我正在使用iOS聊天客户端.有人可以帮我多用户聊天吗？

我已经实现了Robbiehanson的XMPPFramework.

谁能告诉我如何获取组列表并使用此框架在服务器中创建组？

提前致谢.

我在ubuntu 10.04上配置并安装了couchdb 1.6.1.虽然配置和安装它说成功完成了.但是,当我启动couchdb时,它给了我错误.

什么时候开始..

Apache CouchDB 1.6.1 (LogLevel=info) is starting.

Apache CouchDB has started. Time to relax.

**[info] [<0.32.0>] Apache CouchDB has started on http://127.0.0.1:5984/**

再次开始时

 Apache CouchDB 1.6.1 (LogLevel=info) is starting.

我正在开发一个项目,其中我使用了AudioUnitRender,它在模拟器中运行良好,但在设备中出现-50错误.

如果有人遇到类似的问题,请给我一些解决方案.

RIOInterface* THIS = (RIOInterface *)inRefCon;
COMPLEX_SPLIT A = THIS->A;
void *dataBuffer = THIS->dataBuffer;
float *outputBuffer = THIS->outputBuffer;
FFTSetup fftSetup = THIS->fftSetup;

uint32_t log2n = THIS->log2n;
uint32_t n = THIS->n;
uint32_t nOver2 = THIS->nOver2;
uint32_t stride = 1;
int bufferCapacity = THIS->bufferCapacity;
SInt16 index = THIS->index;

AudioUnit rioUnit = THIS->ioUnit;
OSStatus renderErr;
UInt32 bus1 = 1;

renderErr = AudioUnitRender(rioUnit, ioActionFlags, 
    inTimeStamp, bus1, inNumberFrames, THIS->bufferList);
NSLog(@"%d",renderErr);
if (renderErr < 0) {
    return renderErr;
}

有关样本大小和框架的数据......

bytesPerSample = sizeof(SInt16);
asbd.mFormatID = …

我在服务器上有ubuntu 10.04.我正在尝试设置蛋糕php项目,但它给了我以下错误

   Cake is NOT able to connect to the database.

   Datasource class MySQL could not be found.

我在网上搜索了很多相关内容.我的配置文件看起来像这样

  class DATABASE_CONFIG {

public $default = array(
    'datasource' => 'Database/MySQL',
    'persistent' => false,
    'host' => 'localhost',
    'login' => 'root',
    'password' => 'mypassword',
    'database' => 'dbname',
    'prefix' => '',
    //'encoding' => 'utf8',
);
 }

我检查了服务器已经设置了所有设置连接作为PDO我运行以下脚本,它工作正常.

    $conn = new PDO('mysql:host=localhost;dbname=dbname', $username, $password);

然后我进一步改变了蛋糕php的Mysql.php文件,它位于"lib\Cake\Model\Datasource\Database"中

我试图在Mysql.php中提供静态连接,但这也不起作用.我确实退出了Mysql.php,似乎控制页面没有到达这里.

    $this->_connection = new PDO('mysql:host=localhost;dbname=dbname', $username, $password);
$this->connected = true;

如果我遗漏任何东西,请告诉我.
