Mutual conversion between NSString and NSDate objects

NSString to NSData object

[Cpp] NSData * xmlData = [@ "testdata" dataUsingEncoding: NSUTF8StringEncoding];
NSData * xmlData = [@ "testdata" dataUsingEncoding: NSUTF8StringEncoding]; NSData is converted to an NSString object

[Cpp] NSData * data;
NSString * result = [[NSString alloc] initWithData: data encoding: NSUTF8StringEncoding];
NSData * data;
NSString * result = [[NSString alloc] initWithData: data encoding: NSUTF8StringEncoding]; NSData is converted to char *

[Cpp] NSData * data;
Char * test = [data bytes];
NSData * data;
Char * test = [data bytes]; char * is converted to an NSData object.
[Cpp] byte * tempData = malloc (sizeof (byte) * 16 );
NSData * content = [NSData dataWithBytes: tempData length: 16];
Byte * tempData = malloc (sizeof (byte) * 16 );
NSData * content = [NSData dataWithBytes: tempData length: 16];
