ios - 按顺序显示编辑的NSString

Question

在这个很棒的社区的帮助下，我已经为此工作了几天。

我有一个NSArray，我需要在其中编辑NSStrings。我设法检测到字符串中的标记并将其加粗。但是，现在我尝试按字符串在NSArray中的顺序显示它们，同时保持添加到特定字符串的粗体。

我可以显示单个粗体字符串'string'，但我需要将其显示在数组中。我知道stringByAppendingString，但这会放在结尾。

任何方向都将是辉煌的。

for (NSString *testWord in legislationArray) {
            if ([testWord rangeOfString:@"BOLDME"].location != NSNotFound) {

            //Remove Marker
            NSString *stripped = [testWord stringByReplacingOccurrencesOfString:@"BOLDME" withString:@""];

            //Get string and add bold
            NSMutableAttributedString *string = [[NSMutableAttributedString alloc] initWithString:stripped];

            NSRange selectedRange = [stripped rangeOfString:(stripped)];

            [string beginEditing];

            [string addAttribute:NSFontAttributeName
                           value:[UIFont fontWithName:@"Helvetica-Bold" size:18.0]
                           range:selectedRange];

            [string endEditing];

            //Where to go now with string?

        }
    }
    cell.dynamicLabel.text = [legislationArray componentsJoinedByString:@"\n"];

根据下面的答案，我可以正常工作，但是粗体方法会调用此错误:

只需使用其他数组即可。将您的代码更改为

NSMutableAttributedString *attrString = [[NSMutableAttributedString alloc] init];
for (NSString *testWord in legislationArray) {
    if ([testWord rangeOfString:@"BOLDME"].location != NSNotFound) {

        //Remove Marker
        NSString *stripped = [testWord stringByReplacingOccurrencesOfString:@"BOLDME" withString:@""];

        //Get string and add bold
        NSMutableAttributedString *string = [[NSMutableAttributedString alloc] initWithString:stripped];

        NSRange selectedRange = [stripped rangeOfString:(stripped)];

        [string beginEditing];

        [string addAttribute:NSFontAttributeName
                       value:[UIFont fontWithName:@"Helvetica-Bold" size:18.0]
                       range:selectedRange];

        [string endEditing];

        //Where to go now with string?
        [attrString appendAttributedString:string];
    }
    else
    {
        [attrString appendAttributedString:[[NSAttributedString alloc] initWithString:testWord]];
    }
    // NEW LINE
    [attrString appendAttributedString:[[NSAttributedString alloc] initWithString:@"\n"]];
}
cell.dynamicLabel.attributedText = attrString;

您的其他问题不是错误-这是XCode在调试窗口中显示属性字符串的一种方式:
