TextField遮挡问题

问下，如何接收点击TextField的消息？或者当我点击textfield时候弹出键盘的消息？？？键盘在输入时候的事件我如何响应啊？？？？？？？？？我会c＋＋不会objective－c，求大神帮忙啊？？？？？？？？？？？？？？ --------------------编程问答-------------------- 在TextField所在的UIViewController里实现UITextFieldDelegate协议

- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField;        // return NO to disallow editing.

- (void)textFieldDidBeginEditing:(UITextField *)textField;           // became first responder

- (BOOL)textFieldShouldEndEditing:(UITextField *)textField;          // return YES to allow editing to stop and to resign first responder status. NO to disallow the editing session to end

- (void)textFieldDidEndEditing:(UITextField *)textField;             // may be called if forced even if shouldEndEditing returns NO (e.g. view removed from window) or endEditing:YES called



- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string;   // return NO to not change text



- (BOOL)textFieldShouldClear:(UITextField *)textField;               // called when clear button pressed. return NO to ignore (no notifications)

- (BOOL)textFieldShouldReturn:(UITextField *)textField;

只要在头部实现了代理就可以调出键盘的，如果想有其他的操作则对代理类下的代码进行实现。 --------------------编程问答-------------------- 除 --------------------编程问答-------------------- 除
