按顺序显示编辑的 NSString [英] Display edited NSString in order

问题描述

在这个伟大社区的帮助下，我已经为此工作了几天.

I have been working on this for a few days with help from this great community.

我有一个 NSArray，我需要在其中编辑 NSStrings.我已经设法检测到字符串中的标记并将其设为粗体.但是现在我试图按照它们在 NSArray 中的顺序显示字符串，同时保持添加到特定字符串的粗体.

I have a NSArray that I need to edit NSStrings within. I have managed to detect a marker in the string and make it bold. However now I am trying to display the strings in the order that they are within the NSArray whilst maintaining the Bold that was added to the specific strings.

我可以显示单个粗体字符串 'string' 但我需要它，以便它在数组中.我知道 stringByAppendingString 但这会把它放在最后.

I can display the individual Bold String 'string' but I need it to be in order that it is within the array. I know of stringByAppendingString but this would put it at the end.

任何方向都会很棒.

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，我得到了它的工作，但是大胆的方法调用了这个错误:

Based on the answers below I got it working however the bold method invokes this error:

推荐答案

只需使用额外的数组.将您的代码更改为

Just use additional array. Change your code to

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;

更新:

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

Your additional issue is not a error - this is a way how XCode shows attributed strings in debug window:
