I am trying to implement a "Done" button in a UIPickerView Similar to the one under this link
I looked in the class reference but I couldn t find it
Thanks
The easiest way to do it is to model it in Interface Builder. It is a UIView
containing a UIToolbar
and a UIPickerView
.
Then create an outlet for the UIView
and connect it.
If you then have a UITextField
you can assign your custom view to its inputView
property.
[self.textField setInputView:self.customPicker];
Alternatively you can add the picker to your main view...
- (void)viewDidLoad
{
[super viewDidLoad];
self.customPicker.frame = CGRectMake(0, CGRectGetMaxY(self.view.frame), CGRectGetWidth(self.customPicker.frame), CGRectGetHeight(self.customPicker.frame));
[self.view addSubview:self.customPicker];
}
... and then use this method to show or hide the picker.
- (void)setPickerHidden:(BOOL)hidden
{
CGAffineTransform transform = hidden ? CGAffineTransformIdentity : CGAffineTransformMakeTranslation(0, -CGRectGetHeight(self.customPicker.frame));
[UIView animateWithDuration:0.3 animations:^{
self.customPicker.transform = transform;
}];
}
