How to resolve this problem

I need data of my png file into 1 NSString

Answer 1

Every subclass of NSObject has a -description method, including NSData:

NSString *finaldata2String = [finaldata2 description];

For NSData this will create an NSString representation of the data, making a string of bytes in hexadecimal format.
