Sprintf-Objective C

Question

I have this code.

sprintf((char *)pData,"%c%02X%c%02X% 02X",ASCII_STX,m_uSessionId,m_chSequenceChar,m_nMessageId,m_uVersion); NSLog("%@",pData); 

But its not printing me contents pData. Tried with %d as a format specifier.

Answer 1

Try the following. It may not recognize pData as a string:

 NSLog( @"%s", pData ); 

Answer 2

Perhaps you will use the Obj-C method?

 NSString *pData = [NSString stringWithFormat:@"%c%02X%c%02X%02X", ASCII_STX, m_uSessionId, m_chSequenceChar, m_nMessageId, m_uVersion]; NSLog(@"%@",pData);
