In Java I have a byte array representation which in iOS I have represented as NSData.
Everything works fine - it's just that some access methods seem rather clumsy in iOS compared to Java.
Accessing a single byte in Java: byteArray[i]
while in iOS I keep using this where byteArray is a NSData:
Byte b;
[byteArray getBytes: &b range: NSMakeRange( i, 1 )];
Isn't there a more direct way of writing this similar to Java?
Well considering not using a NSData Object you could transform it to a const void* like this.
NSdata *data = your data stuff
NSUInteger i = 1;
const char * array = [data bytes];
char c = array[i];
Note This kind of array is read only! (const void *)
Otherwise you'll have to use the functions you already mentioned or some others Apple provides.
Edit
Or you could add some category to NSData
@interface NSData(NSDataAdditions)
- (char)byteAtIndex:(NSUInteger)index;
@end
@implementation NSData(NSDataAdditions)
- (char)byteAtIndex:(NSUInteger)index {
char c;
[self getBytes: &c range: NSMakeRange( index, 1 )];
return c;
}
@end
And then access your Array like this:
NSdata *data = your data stuff
char c = [data byteAtIndex:i];
