[field2 resignFirstResponder];

UITextView沒有事件動作。

Import <UITableViewDelegate, UITableViewDataSource> in header file and use below code to disapear keyboard when click on return button. 

- (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text 
{ 

    if ([text isEqualToString:@"\n"]) { 

     [self.textView resignFirstResponder]; 
     // Return FALSE so that the final '\n' character doesn't get added 
     return NO; 
    } 
    // For any other character return TRUE so that the text gets added to the view 
    return YES; 
}
