lassen Sie uns dies versuchen und Ausgabe überprüfen,

ViewDidLoad

UITapGestureRecognizer *tapGesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(refreshData:)]; 
tapGesture.delegate = self; 
[self.view addGestureRecognizer:tapGesture]; 

#pragma mark Gesture delegate 
- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch { 
if (touch.view == self.view) 
    return YES; 
    return NO; 
} 

- (IBAction)refreshData:(id)sender 
{ 
    isfiltered=NO; 
    [tabvw reloadData]; 
}
