将char转换为字符串

Question

我的代码工作得很好,直到知道,如果我在文本字段中输入一个双位数字(如12),nslog返回2个单位数字(如1和2).现在我需要将这2个单位数字放入2个字符串中.有人可以帮助我吗 提前致谢.

    NSString *depositOverTotalRwy = [NSString stringWithFormat:@"%@", [deposit text]];
NSArray *components = [depositOverTotalRwy
                       componentsSeparatedByString:@"/"];
NSString *firstThird = [components objectAtIndex:0];
  for(int i = 0; i < [firstThird length]; i++)
{
   char extractedChar = [firstThird characterAtIndex:i];
   NSLog(@"%c", extractedChar);
}

Answer 1

你应该可以使用-stringWithFormat:.

NSString *s = [NSString stringWithFormat:@"%c", extractedChar];

编辑:

您可以将它们存储在一个数组中.

NSMutableArray *digits = [NSMutableArray array];

for ( int i = 0; i < [s length]; i++ ) {
    char extractedChar = [s characterAtIndex:i];

    [digits addObject:[NSString stringWithFormat:@"%c", extractedChar]];
}
