Converting NSString to unichar in iOS

Question

I have seen questions in stackoverflow that convert unichar to NSString but now I would like to do the reverse.

How do i do it?

Need some guidance.. Thanks

For example, I have an array of strings:[@"o",@"p",@"q"];

These are strings inside. How do i convert it back to unichar?

Answer 1

The following will work as long as the first character isn't actually two composed characters (in other words as long as the character doesn't have a Unicode value greater than \UFFFF):

unichar ch = [someString characterAtIndex:0];

Answer 2

You could convert it to a buffer in NSData:

if ([string canBeConvertedToEncoding:NSUnicodeStringEncoding]) {
    NSData * data = [string dataUsingEncoding:NSUnicodeStringEncoding];
    const unichar* const ptr = (const unichar*)data.bytes;
    ...
}
