Ios 如何使用SLRequest获取twitter时间线
我正在尝试将Twitter时间线添加到我的iOS应用程序中。 Twitter在此处提供了官方示例代码：Ios 如何使用SLRequest获取twitter时间线,ios,twitter,Ios,Twitter,我正在尝试将Twitter时间线添加到我的iOS应用程序中。 Twitter在此处提供了官方示例代码： 我的问题是：在第70行 if (timelineData) { NSLog(@"Timeline Response: %@\n", timelineData); } 时间线数据已成功打印到控制台。 我试图补充 self.dict = timelineDate; 及 在函数末尾，但实际上它返回一个空字典。 我注意到这个过程是在另一个线程中完成的，所以我尝试了 dispatch_as
我的问题是：在第70行
if (timelineData) {
NSLog(@"Timeline Response: %@\n", timelineData);
}
self.dict = timelineDate;
dispatch_async(dispatch_get_main_queue(), ^{
self.dict = timelineDate;
};
这可能很容易解决，但我真的无法从苹果或Twitter上找到任何资源。有人能帮忙吗？我使用此功能在我的应用程序中加载推文（与twitter api v1.1兼容，但需要在设备中同步推文帐户）。我使用TWRequest进行此操作。您也可以使用SLRequest进行此操作

希望它有用。问题是对api的调用是异步的。这意味着当您重新运行数组时，它还没有被填充。Satheeshwara的答案是解决这个问题的一种方法：在下载完成时发送通知。另一种方法是创建一个在downloa之后调用的委托方法D
这是一种经常出现的模式。brainray提供了一种解决方案。如果您在TableViewController中加载推文，则更简单的方法是只需调用
[self.tableView reloadData]dispatch_async//include twitter.framework
