Question

This probably sounds harder than it is. I’m actually trying to chain some animations together to make it look smooth. What I’m doing is some basic animation of a UIPickerView that slides from the bottom of the screen and when it is dismissed it slides back to the bottom of the screen. I handle this functionality in two methods - (void)showPicker and - (void)hidePicker

Directly after the picker has been hidden I want to show the keyboard, but I don’t want to show the keyboard before the picker has been hidden.

Also I want to this the other way around, directly after the keyboard has been hidden I want to show the UIPickerView. I know I can observe notifications of UIKeyboardDidShowNotification and UIKeyboardDidHideNotification

So what would be the best way to deal with this so that these animations are chained together in a smooth way?

Answer 1

For the path picker->keyboard try

[UIView animateWithDuration:0.3
                 animations:^{
                     [self hidePicker];
                 }
                 completion:^(BOOL finished){
                     [yourInputView becomeFirstResponder];
                 }];

The other way around listen to UIKeyboardDidHideNotification and invoke showPicker in the callback.
