myData is declared like this:
NSData *myData = [NSData dataWithContentsOfFile:thePath];

myData2 is declared like this:
NSData *myData2;

When trying this code I get a error message saying:
*** -[NSConcreteData getBytes:range:]: location 1 exceeds data length 1

// check to see if myData2 holds the right values
for (i = 0; i < 4080; i++)
{
myRange.location = i;
[myData2 getBytes:&buffer1 range:myRange];
NSLog(@"X", buffer1);
}

But looking at myData works. What's the problem here?

Dear list!

I have a NSData object and wonder how I can look at all the bytes inside it with the help of NSLog?

Example: Lets say I have 1000 bytes in the NSData object and I want to look at all the bytes in a loop, how?

Peter
