Rayfleck is on right track.

When you want to close the keyboard due to a textfield somewhere in your view, use following & let iOS handle the responder chain

[self.view endEditing:YES];

This is really helpful when there is a table in the view and the table has textfields everywhere.

From Apple Doc:

- (BOOL)endEditing:(BOOL)force

Description Causes the view (or one of its embedded text fields) to resign the first responder status. This method looks at the current view and its subview hierarchy for the text field that is currently the first responder. If it finds one, it asks that text field to resign as first responder. If the force parameter is set to YES, the text field is never even asked; it is forced to resign. Parameters
force
Specify YES to force the first responder to resign, regardless of whether it wants to do so. Returns YES if the view resigned the first responder status or NO if it did not.
