ios - 如何将字符串拆分为两行标签

Question

我在标签的文本中有一个带有符号的两个单词的字符串，类型为“&”或“/”，如何将第一个带有符号的字符串放在第一行，第二个字符串放在第二行？

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){
            //.....
        }
  }

我哪里错了？

在代码示例中，您firstString使用secondString. 您要做的是添加text一次设置属性并\n在字符串之间添加一个：

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){
            //.....
        }
  }
