NSString with Emojis

Question

I have a NSArray containing NSStrings with emoji codes in the following format: 0x1F463 How can I now convert them into a NSString with the correct format? With this method I am able to generate an "Emoji"-NSString: ``` NSString *emoji = [NSString stringWithFormat:@"\U0001F463"]; ``` But this is only possible with constant NSStrings. How can I convert the whole NSArray?

Accepted Answer

Not my best work, but it appears to work:

```
for (NSString *string in array)
{
    @autoreleasepool {
        NSScanner *scanner = [NSScanner scannerWithString:string];
        unsigned int val = 0;
        (void) [scanner scanHexInt:&val];
        NSString *newString = [[NSString alloc] initWithBytes:&val length:sizeof(val) encoding:NSUTF32LittleEndianStringEncoding];
        NSLog(@"%@", newString);
        [newString release]; // don't use if you're using ARC
    }
}
```

Using an array of four of your sample value, I get four pairs of bare feet.
