隱藏鍵盤總結

1. [view endEditing:YES]  

2. [textFiled resignFirstResponder]  

3.重寫touch事件來實現對鍵盤的隱藏

    [self.view setUserInteractionEnabled:YES];
    UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(tapAction:)];
    [self.view addGestureRecognizer:tap];
    [tap release];

- (void)tapAction:(UITapGestureRecognizer *)tap
{
    NSLog(@"隱藏鍵盤");
    [_text_name resignFirstResponder];
    [_text_number resignFirstResponder];
}
