UIText​Checker

NSString *str = @"hipstar";
UITextChecker *textChecker = [[UITextChecker alloc] init];
NSRange misspelledRange = [textChecker rangeOfMisspelledWordInString:str range:NSMakeRange(0, [str length]) startingAt:0 wrap:NO language:@"en_US"];
NSArray *guesses = [NSArray array];
if (misspelledRange.location != NSNotFound) { 
    guesses = [textChecker guessesForWordRange:misspelledRange inString:str language:@"en_US"]; 
    NSLog(@"First guess: %@", [guesses firstObject]);
     // First guess: hipster
} else { 
    NSLog(@"Not found");
}

猜想结果

["hipster", "hip star", "hip-star", "hips tar", "hips-tar"]

学习功能：

// 学习一个新的单词
[UITextChecker learnWord:str];

NSRange misspelledRange = [textChecker rangeOfMisspelledWordInString:str range:NSMakeRange(0, [str length]) startingAt:0 wrap:NO language:@"en_US"];

结果呢？

NSString *partial = @"hipst";
NSArray *completions = [textChecker completionsForPartialWordRange:NSMakeRange(0, [partial length]) inString:partial language:@"en_US"];
// completions == ["hipster", "hipsters"]
