ios - Objective-C - InputStream 到 NSString

Question

我是 Objective C 的新手，所以我正在尝试做我通常在 Java 中做的事情，比如将 InputStream 转换为 String。基本上，我想在 Objective C 中编写这段 Java 代码...

InputStream in = … //An inputStream i got from http request

BufferedReader reader = new BufferedReader(new InputStreamReader(in));
StringBuilder str = new StringBuilder();
String line = null;

while ((line = reader.readLine()) != null) {
    str.append(line);
}

String myString = str.toString();
in.close();

希望我的问题描述的足够清楚! :)

谢谢!

好吧，Caleb 是对的，但要回答这个问题:

NSInputStream *inputStream = [[NSInputStream alloc] init];
uint8_t buffer[1024];
int len;
NSMutableString *total = [[NSMutableString alloc] init];
while ([inputStream hasBytesAvailable]) {
    len = [inputStream read:buffer maxLength:sizeof(buffer)];
    if (len > 0) {
        [total appendString: [[NSString alloc] initWithBytes:buffer length:len encoding:NSASCIIStringEncoding]];
    }
}

您的编码参数可能不同。
