NSData to NSMutableData conversion

Question

is there some way to convert an NSData object, into an NSMutableData one? Basically I am using NSJSONSerialization which basically takes some JSON data I receive and transforms it into an NSData object instance. Is there anyway to then transform this into an NSMutableData object instance? I need to do this because later on, I will be spawning some threads and within the code blocks I provide, I would like to change the value of the Data object. I can't do that if its NSData but I can if its NSMutableData.

Answer 1

NSMutableData * data = [NSMutableData dataWithData:jsonData];

This should solve your problem.

Answer 2

You can use below code:

NSData *data = ...;
NSMutableData *mutableData = [[NSMutableData alloc] initWithData:data];
