iOS 自定义UITextField1、在TextField的右侧添加view+手势 左侧和右侧同理2、在TextField在键盘上添加‘完成’按钮

引用

NHTextFieldKeyWord *textField = [[NHTextFieldKeyWord alloc] init];

textField.NHKeyWordDelegate = self;

其他设置按继承类使用

代理方法

完成按钮点击

- (void)doneBtnWithTextFile:(UITextField *)textField{}

右侧添加按钮点击

- (void)addBtnActionWithTextFile:(UITextField *)textField{}
