Since you want to remove diacritic marks, you could use this method in combination with the common string manipulating methods, like this:

/* create a locale where diacritic marks are not considered important, e.g. US English */
NSLocale *locale = [[[NSLocale alloc] initWithLocaleIdentifier:@"en-US"] autorelease];

NSString *input = @"Àlter";

/* get first char */
NSString *firstChar = [input substringToIndex:1];

/* remove any diacritic mark */
NSString *folded = [firstChar stringByFoldingWithOptions:NSDiacriticInsensitiveSearch locale:locale];

/* create the new string */
NSString *result = [[folded uppercaseString] stringByAppendingString:[input substringFromIndex:1]];
