解决方法
好.以下是动画要求的示例代码.
- (void) showView
{
[self.view addSubview:yourDatePickerView];
yourDatePickerView.frame = CGRectMake(0,-250,320,50);
[UIView animateWithDuration:1.0
animations:^{
yourDatePickerView.frame = CGRectMake(0,152,260);
}];
}
以下是隐藏DatePickerView的方法
- (void) hideView
{
[UIView animateWithDuration:0.5
animations:^{
yourDatePickerView.frame = CGRectMake(0,50);
} completion:^(BOOL finished) {
[yourDatePickerView removeFromSuperview];
}];
}
- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField
{
if(textField == yourDateTextField)
{
[self showView];
return NO; // preventing keyboard from showing
}
return YES;
}
- (void)textFieldDidEndEditing:(UITextField *)textField
{
if(textField == yourDateTextField)
{
[self hideView];
}
}
这就是你所需要的一切.
