facebook登录随机报错 Error Domain=com.

facebook报错：
Error Domain=com.facebook.sdk.login Code=308 "(null)"

我当前解决方法是：找到这个文件FBSDKUtility.m 大概第 63 行开始，用以下代码替换这两个方法即可

+ (NSString *)URLDecode:(NSString *)value
{
  value = [value stringByReplacingOccurrencesOfString:@"+" withString:@" "];
#pragma clang diagnostic push
#pragma clang diagnostic ignored "-Wdeprecated-declarations"
  value = [value stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
#pragma clang diagnostic pop
  return value;
}

#pragma clang diagnostic push
#pragma clang diagnostic ignored "-Wdeprecated-declarations"
+ (NSString *)URLEncode:(NSString *)value
{
  return (__bridge_transfer NSString *)CFURLCreateStringByAddingPercentEscapes(NULL,
                                                                               (CFStringRef)value,
                                                                               NULL, // characters to leave unescaped
                                                                               CFSTR(":!*();@/&?+$,='"),
                                                                               kCFStringEncodingUTF8);
}
#pragma clang diagnostic pop
