Discussion of [NSString NSUTF32BigEndianStringEncoding]

These values represent the various character encodings supported by the NSStringclasses. This is an incomplete list. Additional encodings are defined in String Programming Guide for Core Foundation (see CFStringEncodingExt.h); these encodings can be used with NSString by first passing the Core Foundation encoding to the CFStringConvertEncodingToNSStringEncoding function.

Example of [NSString NSUTF32BigEndianStringEncoding]

NSString *str = @"😄 H€llö Wòrld";
NSData *data = [str dataUsingEncoding:NSUTF32BigEndianStringEncoding];
NSLog(@"%@", data);

const uint8_t *bytes = [data bytes]; // pointer to converted bytes
NSUInteger length = [data length];   // number of converted bytes

Example of [NSString NSUTF32BigEndianStringEncoding]

- (void)GetData
{
    url = [NSURL URLWithString:@"http://ar2.co/savola/"];
    jsonreturn = [[NSString alloc] initWithContentsOfURL:url];
    NSLog(jsonreturn);
    jsonData = [jsonreturn dataUsingEncoding:NSUTF32BigEndianStringEncoding];
    dict = [[[CJSONDeserializer deserializer] deserializeAsDictionary:jsonData error:&error] retain];
    rows = [dict objectForKey:@"savola"];
    NSLog(@"Array: %@",rows);

   [yourTable reloadData];
}

Example of [NSString NSUTF32BigEndianStringEncoding]

NSString* result = [[NSString alloc] initWithBytes: (const void*)buffer 
                                            length: sizeof(wchar_t) * numberOfCharsInBuffer
                                          encoding: NSUTF32BigEndianStringEncoding];
