1.在摸個界面完全禁用IQKeyboard

- (void)viewWillAppear:(BOOL)animated {
    [super viewWillAppear:animated];

    //TODO: 頁面appear 禁用
   [[IQKeyboardManager sharedManager] setEnable:NO];
}

- (void)viewWillDisappear:(BOOL)animated {
    [super viewWillDisappear:animated];

    //TODO: 頁面Disappear 啟用
   [[IQKeyboardManager sharedManager] setEnable:YES];
}

2.在摸個界面完全禁用IQKeyboard 的 Toolbar (完成、切換箭頭)

- (void)viewWillAppear:(BOOL)animated {
    [super viewWillAppear:animated];

    //TODO: 頁面appear 禁用
   [[IQKeyboardManager sharedManager] setEnableAutoToolbar:NO];
}

- (void)viewWillDisappear:(BOOL)animated {
    [super viewWillDisappear:animated];

    //TODO: 頁面Disappear 啟用
   [[IQKeyboardManager sharedManager] setEnableAutoToolbar:YES];
}

3.在摸個界面完全禁用IQKeyboard 的 Toolbar 的 切換箭頭(切換輸入框)

typedef NS_ENUM(NSUInteger, IQPreviousNextDisplayMode) {
    IQPreviousNextDisplayModeDefault,        默認一界面多輸入框顯示切換箭頭  單輸入框不顯示
    IQPreviousNextDisplayModeAlwaysHide,     隱藏切換箭頭
    IQPreviousNextDisplayModeAlwaysShow,     一直顯示切換箭頭(不受輸入框個數(shù)限制) 
};

- (void)viewWillAppear:(BOOL)animated {
    [super viewWillAppear:animated];

    //TODO: 頁面appear 禁用
   [IQKeyboardManager sharedManager] .previousNextDisplayMode = IQPreviousNextDisplayModeAlwaysHide;
}

- (void)viewWillDisappear:(BOOL)animated {
    [super viewWillDisappear:animated];

    //TODO: 頁面Disappear 啟用
   [IQKeyboardManager sharedManager] .previousNextDisplayMode = IQPreviousNextDisplayModeAlwaysShow;
}
