Question

我有一个两个单词的字符串，在“＆amp;”类型的中间有一个符号在标签的文本中左右“/”，如何在第一行中放置带符号的第一个字符串，在第二行中放置第二个字符串？

这是代码

if(self.labelTitle.text.length> self.labelTitle.bounds.size.width){
     self.labelTitle.numberOfLines =2;

       if([self.labelTitle.text rangeOfString:@"&"].location != NSNotFound){
            NSArray * separateString = [self.labelTitle.text componentsSeparatedByString:@"&"];
            NSString * firstString =[separateString objectAtIndex:0];
            NSString *secondString =[separateString objectAtIndex:1];
            self.labelTitle.text = firstString;
            self.labelTitle.text = secondString;

        }else if ([self.labelTitle.text rangeOfString:@"/"].location != NSNotFound){
            //.....
        }
  }

哪里错了？

在代码示例中，您使用firstString覆盖secondString。您要做的是添加一次text属性并在字符串之间添加\n：

if(self.labelTitle.text.length> self.labelTitle.bounds.size.width){
     self.labelTitle.numberOfLines =2;

       if([self.labelTitle.text rangeOfString:@"&"].location != NSNotFound){
            NSArray * separateString = [self.labelTitle.text componentsSeparatedByString:@"&"];
            NSString * firstString =[separateString objectAtIndex:0];
            NSString *secondString =[separateString objectAtIndex:1];
            self.labelTitle.text = [NSString stringWithFormat:@"%@\n%@", firstString, secondString];

        }else if ([self.labelTitle.text rangeOfString:@"/"].location != NSNotFound){
            //.....
        }
  }

如何将字符串拆分为双行标签
