有人可以描述如何使用“NSURLErrorCancelled = -999”.
解决方法
来自Apple文档:
NSURLErrorCancelled (-999)
“Returned when an asynchronous load is canceled. A Web Kit framework
delegate will receive this error when it performs a cancel
operation on a loading resource. Note that an NSURLConnection or
NSURLDownload delegate will not receive this error if the download is
canceled.”
你可以做的最好的事情就是忽略这个错误
if ([error code] != NSURLErrorCancelled) { //here you'll get a real error }
