Question

我使用以下代码计算单词总数

-(NSInteger) getTotalWords{
    NSLog(@"Total Word %lu",[[_editor.attributedText string]length]);
    if ([[_editor.attributedText string]length]==0) {
        return 0;
    }

    NSString *str  =[_editor textInRange:[_editor textRangeWithRange:[self visibleRangeOfTextView:_editor]]];

    NSInteger sepWord = [[[str stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet]]componentsSeparatedByString:@" "] count];
    sepWord += [[[str stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet]]componentsSeparatedByString:@"\n"] count];
    sepWord=sepWord-2;
    return sepWord;
}

这是总字符的代码

 -(NSInteger) getTotalChars{

        NSString *str  =[_editor textInRange:[_editor textRangeWithRange:[self visibleRangeOfTextView:_editor]]];

        NSLog(@"%@",str);

        NSInteger charCount= [[str stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet]]length];

        return charCount=charCount-1;

    }

但是当我输入两行以上时，我得不到完美的计数。它需要换行...

请帮助.. !!!

Answer 1

如果你真的想要计算单词（即“foo，bar”应该算作2个单词然后是6个字符您可以使用NSStringEnumerationByWords的{{1}}选项，它会自动处理所有空格和字分隔符：

enumerateSubstringsInRange

Answer 2

你可以这样做：

NSString *text = @"Lorem ...";

NSArray *words = [text componentsSeparatedByCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];
NSInteger wordCount = [words count];

NSInteger characterCount = 0;
for (NSString *word in words) {
   characterCount += [word length];
}

Answer 3

一旦尝试这样，

 NSString *string = @"123 1 2\n234\nponies";
    NSArray *chunks = [string componentsSeparatedByCharactersInSet:[NSCharacterSet characterSetWithCharactersInString:@" \n"]];
    NSLog(@"%d",[chunks count]);

Answer 4

字数统计......

NSString *str = @"this is a sample string....";
NSScanner *scanner = [NSScanner scannerWithString:str];
NSCharacterSet *whiteSpace = [NSCharacterSet whitespaceAndNewlineCharacterSet];
NSCharacterSet *nonWhitespace = [whiteSpace invertedSet];
int wordcount = 0;

while(![scanner isAtEnd])
{
    [scanner scanUpToCharactersFromSet:nonWhitespace intoString:nil];
    [scanner scanUpToCharactersFromSet:whitespace intoString:nil];
    wordcount++;
}

Answer 5

int characterCount = 0;

使用字数 -

NSArray *array = [txtView.text componentsSeparatedByString:@" "];
int wordCount = [array count];

for(int i = 0; i < [array count]; i++){
    characterCount = characterCount + [[array objectAtIndex:i] length];
}

NSLog(@"characterCount : %i",characterCount);
NSLog(@"wordCount : %i",wordCount);

Answer 6

    str = textView.text;

    NSArray *wordArray = [str componentsSeparatedByString:@" "];

    int wordCount = [wordArray count];
    int charCount=0;

    for (int i=0 ; i < [wordArray count]; i++)
    {
        charCount = charCount + [[wordArray objectAtIndex:0] length];
    }

如何计算textView中的单词和字符总数？
