一個讓我不舒服的自定義鍵盤

根據需求做,真的好惡心,但是仔細研究一下蠻簡單的
剛開始做的時候,要關閉原生鍵盤的彈出
self.sellingPricetext.inputView = [[UIView alloc] initWithFrame:CGRectZero];
[self.sellingPricetext setDelegate:self];
self.originalPriceText.inputView = [[UIView alloc] initWithFrame:CGRectZero];
[self.originalPriceText setDelegate:self];

鍵盤輸入的界面我是用xib畫的,簡單,但是後期改動麻煩

輸入的時候需要用NSMutableString來接受輸入的值
self.string1 = [NSMutableString string];
self.string2 = [NSMutableString string];

這些是主要代碼,邏輯並不複雜,剛開始做的時候是不知道該如何下手

• (IBAction)chooseTheDigital:(UIButton *)sender {

  if ([self.keybordType isEqualToString:@”0”]) {
  [self showHint:@”請選擇出售價格或者原價”];
  return;
  }

  if ([self.keybordType isEqualToString:@”1”]) {
  [self.string1 appendString:sender.currentTitle];
  self.sellingPricetext.text = self.string1;//原價
  }

  if ([self.keybordType isEqualToString:@"2"]) {
  
  [self.string2 appendString:sender.currentTitle];
  self.originalPriceText.text = self.string2;//出售價
  }
  

}

• (IBAction)dele:(UIButton *)sender {

  if ([self.keybordType isEqualToString:@”0”]) {
  [self showHint:@”沒輸入原價或者出售價”];
  return;
  }

  if ([self.keybordType isEqualToString:@”1”]) {
  if ([self.sellingPricetext.text isEqualToString:@”“]) {
  [self showHint:@”請輸入原價”];

  }else{
  [self.string1 deleteCharactersInRange:NSMakeRange(self.string1.length-1, 1)];
  self.sellingPricetext.text = self.string1;
  }
  

  }

  if ([self.keybordType isEqualToString:@”2”]) {
  if ([self.originalPriceText.text isEqualToString:@”“]) {

  }else{

      self.originalPriceText.text = self.string2;
  }
  

  }
