Android 判断是否是是全汉字、全字母、全数字、数字和字母等(代码)

直接看代码吧！！！

#pragma mark 判断只能为中文的
- (bool) zsstringinputonlyischinese:(nsstring*)string
{
  nsstring *regex = @"[\u4e00-\u9fa5]+";
  nspredicate *pred = [nspredicate predicatewithformat:@"self matches %@",regex];
  if ([pred evaluatewithobject:string]) {
    return yes;
  }
  return no;
}
#pragma mark 判断只能为数字的
- (bool) zsstringinputonlyisnumber:(nsstring*)string
{
  nsstring *regex =@"[0-9]*";
  nspredicate *pred = [nspredicate predicatewithformat:@"self matches %@",regex];
  if ([pred evaluatewithobject:string]) {
    return yes;
  }
  return no;
}
#pragma mark 判断只能为字母的
- (bool) zsstringinputonlyisletter:(nsstring*)string
{
  nsstring *regex =@"[a-za-z]*";
  nspredicate *pred = [nspredicate predicatewithformat:@"self matches %@",regex];
  if ([pred evaluatewithobject:string]) {
    return yes;
  }
  return no;
}

#pragma mark 判断只能为字母或数字的
- (bool) zsstringinputonlyisnumber:(nsstring*)string
{
  nsstring *regex =@"[a-za-z0-9]*";
  nspredicate *pred = [nspredicate predicatewithformat:@"self matches %@",regex];
  if ([pred evaluatewithobject:string]) {
    return yes;
  }
  return no;
}

以上所述是小编给大家介绍的android 判断是否是是全汉字、全字母、全数字、数字和字母等，希望对大家有所帮助
