nsinputstream到字符串？

Question

无论如何都要查看nsinputstream中的值，例如将其转换为字符串？

Answer 1

I'll assume you mean the data that's returned from NSInputStream:

- (NSInteger)read:(uint8_t *)buffer maxLength:(NSUInteger)len;

Try this:

NSInteger bytesRead = [myInputStream read:&byteBuffer maxLength:4096];
NSString *stringFromData = [[NSString alloc] initWithBytes:byteBuffer length:bytesRead encoding:NSUTF8StringEncoding];

Answer 2

If you are reading the data from a stream that is pointing at a file or a URL, you could NSString methods:

+ stringWithContentsOfFile:encoding:error:
+ stringWithContentsOfURL:encoding:error:

See the NSString class reference for the documentation of these methods.
