问题描述
我有一个处理字符串并将其转换为未知格式并将其插入NSData的库。在库中检查NSData是否为空的代码的一部分,如果不是,它发送到服务器:
I have a library that process a string and converts it to an unknown format and insert it into a NSData. In a part of the code that library check if the NSData is empty, if not it sends to the server:
if (!dataToSend) {
return;
}
我认为存储的值是字符串或base64,因为测试了以下代码:
I thought the stored value would be a string or base64, for that tested the following codes:
NSLog(@"To string -> %@",[NSString stringWithUTF8String:[dataToSend bytes]]);
NSString *decodedString = [[NSString alloc] initWithData:dataToSend encoding:NSUTF8StringEncoding];
NSLog(@"Decode String Value: %@", decodedString);
在控制台中我继续收到(null)
,但是当我从 return;
中插入下面的代码后,数据不为空。我如何检查NSData存储的类型?
In console I continue receiving (null)
, but the data is not null once I insert that code below from return;
. How I can check the type of that NSData stores?
推荐答案
- 检查NSData的类型

if([yourData isKindOfClass:[NSData class]])
