NSDictionary *result = value[@"data"];

if (![result isKindOfClass:[NSDictionary class]]) {

NSLog(@"data 不是字典");

if ([result isKindOfClass:[NSString class]]) {

NSData *data = [(NSString *)result dataUsingEncoding:NSUTF8StringEncoding];// 将数据格式转为UTF8

if (data) {

result = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingAllowFragments error:NULL];

} else {

result = @{};

}

NSLog(@"解析data: %@", result);

} else {

result = @{};

}

// 数组里面放了每个字典

commentlist = "[{\"user_id\":\"1\",

\"content\":\"[\\u998b\\u5634][\\u6293\\u72c2]\",

\"createtime\":\"1970-01-01 08:00:00\",
