Ios 如何使UITextView文本可单击

我有几个字符串由

/

连接，并放置在

UITextview

中。我必须使

/

之前的每个字符串都可单击。我不知道具体的字符串或它的范围。我用轻拍手势识别器给我触摸过的单词，但我想要整个字符串。例如，我的字符串是“ABC-1234/DEF-1234/ghi-9874”。但当我点击它时，我要么得到“abc”要么得到“ghi”。如何获得整个字符串

以下是我当前的代码，它不能按预期工作：

UITextView *textView =  (UITextView *)tapRecognizer.view;
CGPoint location = [tapRecognizer locationInView:textView];    
CGPoint position = CGPointMake(location.x, location.y);
UITextPosition *tapPosition = [textView closestPositionToPoint:position];

UITextRange *textRange = [textView.tokenizer rangeEnclosingPosition:tapPosition withGranularity:UITextGranularityWord inDirection:UITextLayoutDirectionRight];
// NSString *tappedWord = [textView textInRange:textRange];

我尝试使用NSScanner，但也没有成功。下面是使用

NSScanner

的代码。它只给出最后一个值：

NSString *plainString = self.SelectedTextView.attributedText.string;
NSMutableArray* substrings = [[NSMutableArray alloc]init];
NSScanner *scanner = [[NSScanner alloc]initWithString:plainString];
[scanner scanUpToString:@"/" intoString:nil];

while (![scanner isAtEnd]) {
    NSString* substring = nil;
    [scanner scanString:@"/" intoString:nil];
    NSString* space = @" ";
    if ([scanner scanUpToString:space intoString:&substring]) {
        [substrings addObject:substring];
    }
    [scanner scanUpToString:@"/" intoString:nil];
}

NSLog(@"%@",substrings);

感谢您的帮助。提前感谢。

当字符串被分配给textview时，我调用了一个方法，该方法计算所选textview中的元素

-(void)ElementsInSelectedTextView
{
    localizedStringPieces = [NSArray new];
     localizedStringPieces = [_SelectedTextView.text componentsSeparatedByString:@"/"];
     arrMinMax = [[NSMutableArray alloc] init];
    NSUInteger count = 0;
    for (int i = 0; i <[localizedStringPieces count]; i++) {
        NSString * str =[localizedStringPieces objectAtIndex:i];
        NSUInteger length = count + str.length-1;
        NSMutableDictionary * tempdic = [[NSMutableDictionary alloc]init];
        [tempdic setObject:[NSNumber numberWithUnsignedInteger:count] forKey:@"MinValue"];
        [tempdic setObject:[NSNumber numberWithUnsignedInteger:length] forKey:@"MaxValue"];
        [arrMinMax addObject:tempdic];
        count = length +1;

    }

}

在选择器方法中添加以下代码

- (void)SelectedProductTextViewDetected:(UITapGestureRecognizer *)tapRecognizer
{
 NSUInteger characterIndex;
    NSLayoutManager *layoutManager = _SelectedTextView.layoutManager;
    CGPoint location = [tapRecognizer locationInView:_SelectedTextView];
    characterIndex = [layoutManager characterIndexForPoint:location
                                           inTextContainer:_SelectedTextView.textContainer
                  fractionOfDistanceBetweenInsertionPoints:NULL];

    NSString * strValue;
    for (int j = 0; j<[arrMinMax count]; j++) {
        if (characterIndex >=[[[arrMinMax objectAtIndex:j] objectForKey:@"MinValue"] integerValue]  && characterIndex <=[[[arrMinMax objectAtIndex:j] objectForKey:@"MaxValue"] integerValue]) {
            strValue = [localizedStringPieces objectAtIndex:j];
            SelectedProductIndex = j;
        }
    }
 _SelectedTextView.text = strValue;
     [self.SelectedTextView layoutIfNeeded];
    _SelectedTextView.editable = NO;
}

-（void）SelectedProductTextViewDetected:（UITapgestureRecognitor*）点击识别器
{
NSU整数特征索引；
NSLayoutManager*layoutManager=\u选择的TEXTVIEW.layoutManager；
CGPoint location=[点击识别器位置查看：_SelectedTextView]；
characterIndex=[layoutManager CharacterIndexorPoint:位置
inTextContainer:\u选择了TextView.textContainer
插入点之间距离的分位数：NULL]；
NSString*标准值；
对于（int j=0；j=[[arrMinMax objectAtIndex:j]objectForKey:@“MinValue”]integerValue]&&characterIndex，您解决了这个问题吗？是的，我解决了，等我将答案发布到@Abdul Jamil
- (void)SelectedProductTextViewDetected:(UITapGestureRecognizer *)tapRecognizer
{
 NSUInteger characterIndex;
    NSLayoutManager *layoutManager = _SelectedTextView.layoutManager;
    CGPoint location = [tapRecognizer locationInView:_SelectedTextView];
    characterIndex = [layoutManager characterIndexForPoint:location
                                           inTextContainer:_SelectedTextView.textContainer
                  fractionOfDistanceBetweenInsertionPoints:NULL];

    NSString * strValue;
    for (int j = 0; j<[arrMinMax count]; j++) {
        if (characterIndex >=[[[arrMinMax objectAtIndex:j] objectForKey:@"MinValue"] integerValue]  && characterIndex <=[[[arrMinMax objectAtIndex:j] objectForKey:@"MaxValue"] integerValue]) {
            strValue = [localizedStringPieces objectAtIndex:j];
            SelectedProductIndex = j;
        }
    }
 _SelectedTextView.text = strValue;
     [self.SelectedTextView layoutIfNeeded];
    _SelectedTextView.editable = NO;
}
