Ios7 NSURLConnection解析问题

数据未被解析 ServerResponse为空--请求未响应NSURLConnection可能为空

请建议如何解决它。

谢谢

将

else

子句添加到

if（error==nil）

并记录

[error localizedDescription]

，您的知识将得到扩展。像这样尝试，但没有用。。。。数据正确，请求（NSMutableURLRequest）也正确。但当我尝试同步到数据时，所有键值都将变为null。请放置断点并检查字符串中是否包含null值。当我尝试打印字符串时，它将以XML格式打印。“服务器拒绝了此请求，因为请求实体的格式不受请求方法的请求资源的支持。”像什么样打印？你能把你在Nslog中得到的东西放在这里吗？有时它会给出类似CFNetwork SSLHandshake failed（-9810）的结果

NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:SPACEREQUESTFINAL_URL] cachePolicy:NSURLRequestUseProtocolCachePolicy
