本文實例為年夜家分享了IOS自界說鍵盤切換的相干代碼，供年夜家參考，詳細內容以下

詳細代碼以下

- (void)viewDidLoad {
  [super viewDidLoad];
  // Do any additional setup after loading the view, typically from a nib.
  self.title = @"小飛哥鍵盤";
  self.textField = [[UITextField alloc] initWithFrame:CGRectMake(50, 168, kScreenWidth - 100, 50)];
  self.textField.delegate = self;
  self.textField.backgroundColor = [UIColor greenColor];
  self.textField.placeholder = @"(默許體系鍵盤)";
   
  [self.view addSubview:self.textField];
   
  UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithtarget:self action:@selector(hidenKeyBoard)];
  [self.view addGestureRecognizer:tap];
   
  UISegmentedControl *segment = [[UISegmentedControl alloc] initWithItems:@[@"鍵盤1",@"鍵盤2",@"鍵盤3",@"體系鍵盤"]];
  segment.frame = CGRectMake(0, 100, kScreenWidth, 50);
  [segment addTarget:self action:@selector(keyBoardTypeAction:) forControlEvents:UIControlEventValueChanged];
  [self.view addSubview:segment];
   
}
 
- (void)keyBoardTypeAction:(id )sender
{
  UISegmentedControl *seg = (UISegmentedControl *)sender;
  NSLog(@"intage = %ld", (long)seg.selectedSegmentIndex);
   
  if (seg.selectedSegmentIndex == 0) {
    self.xfg_keyboard = [[XFG_KeyBoard alloc] initWithNumber:@1];
    self.textField.inputView = self.xfg_keyboard;
    self.xfg_keyboard.delegate = self;
    [self.textField reloadInputViews];
  }
  if (seg.selectedSegmentIndex == 1) {
    self.xfg_keyboard = [[XFG_KeyBoard alloc] initWithNumber:@2];
    self.textField.inputView = self.xfg_keyboard;
    self.xfg_keyboard.delegate = self;
    [self.textField reloadInputViews];
   
  }
   
  if (seg.selectedSegmentIndex == 2) {
    self.xfg_keyboard = [[XFG_KeyBoard alloc] initWithNumber:@3];
    self.textField.inputView = self.xfg_keyboard;
    self.xfg_keyboard.delegate = self;
    [self.textField reloadInputViews];
  }
   
  if (seg.selectedSegmentIndex == 3) {
    self.textField.inputView = nil;
    [self.textField reloadInputViews];
  }
  
}
