5 years ago syncToKeyboardState:completionHandler: triggered when the keyboard appears . Check out you methodSignatureForSelector: and forwardInvocation: template methods , be careful about the method signature .

The code is: _manager = [[RETableViewManager alloc] initWithTableView:self.tableView]; RETableViewSection *section = [RETableViewSection sectionWithHeaderTitle:@""]; [_manager addSection:section]; _name = [RETextItem itemWithTitle:@"姓名" value:@"123" placeholder:@"姓名"]; [section addItem:_name];
and the crash content is: Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '[NSXPCConnection sendInvocation]: A NULL reply block was passed into a message meant to be sent over a connection.
