Below is my code to make the textfield visible when keyboard is up. Now, it's working fine with the code. However, Giving me warning that may not respond to animateTextField:up. can any1 please help me to remove this warning?
- (void)textFieldDidBeginEditing:(UITextField *)textField
{
[self animateTextField:textField up:YES];
}
- (void)textFieldDidEndEditing:(UITextField *)textField
{
[self animateTextField:textField up:NO];
}
- (void) animateTextField: (UITextField*) textField up: (BOOL) up
{
int animatedDistance;
int moveUpValue = textField.frame.origin.y+ textField.frame.size.height;
UIInterfaceOrientation orientation =
[[UIApplication sharedApplication] statusBarOrientation];
if (orientation == UIInterfaceOrientationPortrait ||
orientation == UIInterfaceOrientationPortraitUpsideDown)
{
animatedDistance = 216-(460-moveUpValue-5);
}
else
{
animatedDistance = 162-(320-moveUpValue-5);
}
if(animatedDistance>0)
{
const int movementDistance = animatedDistance;
const float movementDuration = 0.3f;
int movement = (up ? -movementDistance : movementDistance);
[UIView beginAnimations: nil context: nil];
[UIView setAnimationBeginsFromCurrentState: YES];
[UIView setAnimationDuration: movementDuration];
self.view.frame = CGRectOffset(self.view.frame, 0, movement);
[UIView commitAnimations];
}
}
Put an empty category in .m
file and declare your method in @interface
.
@interface TheClass ()
- (void) animateTextField: (UITextField*) textField up: (BOOL) up;
@end
declare your - (void) animateTextField: (UITextField*) textField up: (BOOL) up
method in your @implementation .h file
or
move that animateTextField
function above your textFieldDidBeginEditing
method so the compiler sees it before it hits that function.
