How to put elements from NSMutableArray into C char?

Question

I have a NSMutableArray and I need to sort its elements into separate C char.

How to accomplish that? Or is it better to put the elements into NSStrings?

I've tried this, and it crashes when I try to log the result:

NSMutableArray *array = [[NSMutableArray alloc] init];

... do something to fill the array ...

NSString *string;

string = [array objectAtIndex:0];

NSLog(@"String: %@", string);

*I really prefer putting the elements of the array into C char, because I already have some woking code using char instead of NSStrin*g.

Thanks!

Please explain, so is array full of NSStrings and you want an array of const char * to sort, or do you actually want a single C char from the strings in your array or what? — Joe

Dont see any specific reason to convert NSString to C chars. To sort an array full of NSStrings try this method -

NSMutableArray *array = [[NSMutableArray alloc] init];
sortedArray = [array sortedArrayUsingSelector:@selector(localizedCaseInsensitiveCompare:)];
NSString *string = [sortedArray objectAtIndex:0];
NSLog(@"String: %@", string);

I receive the warning "Semantic Issue: Incompatible pointer types assigning to 'NSMutableArray *' from 'NSArray *'"

@Winston both arrays sortedArray & array have to be of the same type NSMutableArray or NSArray. Change that & i dont see a reason for this to not work...

I verified that and I only have NSMutableArray. When I "Jump to Definition" on xCode for sortedArrayUsingSelector I get: "- (NSArray *)sortedArrayUsingSelector:(SEL)comparator;"
