本文实例为大家分享了iOS自定义键盘切换的相关代码，供大家参考，具体内容如下

具体代码如下

- (void)viewDidLoad { [super viewDidLoad]; // Do any additional setup after loading the view, typically from a nib. self.title = @"小飞哥键盘"; self.textField = [[UITextField alloc] initWithFrame:CGRectMake(50, 168, kScreenWidth - 100, 50)]; self.textField.delegate = self; self.textField.backgroundColor = [UIColor greenColor]; self.textField.placeholder = @"(默认系统键盘)"; [self.view addSubview:self.textField]; UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(hidenKeyBoard)]; [self.view addGestureRecognizer:tap]; UISegmentedControl *segment = [[UISegmentedControl alloc] initWithItems:@[@"键盘1",@"键盘2",@"键盘3",@"系统键盘"]]; 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]; } }
