SIGABRT启动 [英] SIGABRT on startup

问题描述

我根本不明白这一点.我发现的是一些论坛上的帖子，上面写着我不知道如何解决此问题".我开始了一个简单的看法.然后，我添加了ASIHTTPRequest以使用对php脚本的请求调用与数据库进行通信.在编译之前，我必须添加Reachability.h.当我实际尝试运行它时，我得到的只是模拟器上的空白屏幕，并且主要是XCode中的SIGABRT错误.

I simply don't understand this. All I find is a number of forum posts that say "I don't know how to fix this". I started out a simple view. I then added ASIHTTPRequest to communicate with a database using a request call to a php script. I had to add Reachability.h before it would compile. When I actually tried to run it, all I got was a blank screen on the simulator, and the SIGABRT error in XCode in the main.

以下是输出:

推荐答案

确定要复制正确的输出吗?粘贴的输出显示您添加了一个对象作为UITableViewController的委托，但是没有在以下方法中实现强制性的方法:

Are you sure you copied the right output? The pasted output shows that you added an object as the delegate of a UITableViewController, but without implementing the obligatory methods in:

-[ViewInfoViewController tableView:numberOfRowsInSection:]:

-[ViewInfoViewController tableView:numberOfRowsInSection:]:

除此之外，而且缺少帮助您的代码，我唯一想到的就是您没有添加必需的ASIHTTP框架，或者您安装了错误的可达性(ASI带有它自己的可达性，在另一个文件夹中，它不同于Apple的Reachability，btw).

Aside from that, and the lack of code to help you out, the only thing I can think of is that you didn't add the required Frameworks for ASIHTTP, or you installed the wrong reachability (ASI comes with it's own reachability, inside another folder, it is different from Apple's Reachability, btw).
