UISearchDisplayController 定位问题

Question

当我点击 UISearchBar 时，它改变了它的位置，并且 tableview 与 UISearchBar 重叠。我改变了它的位置，但它不起作用。

-(void)searchDisplayControllerWillBeginSearch:(UISearchDisplayController *)controller {

if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7.0) {

 CGRect statusBarFrame =  [[UIApplication sharedApplication] statusBarFrame];
 [UIView animateWithDuration:0.25 animations:^{
 for (UIView *subview in self.view.subviews)
 subview.transform = CGAffineTransformMakeTranslation(0, statusBarFrame.size.height);
    subview.frame=CGRectMake(0, -200, 320, 64);
 }];
 }

}
