resize UISearchDisplayController dimmed black over

问题:

anybody know how to resize the dimmed black overly, once you clicked the search bar ?

i having problem when i clicked cancelled the tableview will expend then animated to disappear.

i using this to resize my result tableview.

-(void)searchDisplayController:(UISearchDisplayController *)controller didShowSearchResultsTableView:(UITableView *)tableView {
   tableView.frame =fTableView.frame;//CGRectMake(26, 100, 280, 310); //fTableView.frame;
    tableView.backgroundColor = [UIColor colorWithRed:243.0/255.0 green:236.0/255.0 blue:212.0/255.0 alpha:1];   
}

when clicked on the search bar, gray overlay are full instead of my defined size.

when clicked cancel button, the view will expend back.

I combined several answers in order to move the dimmed overlay frame.

1: override UISearchDisplayController class

@interface MySearchController : UISearchDisplayController

2: override setActive function

- (void)setActive:(BOOL)visible animated:(BOOL)animated
{
[super setActive: visible animated: animated];

//move the dimming part down
for (UIView *subview in self.searchContentsController.view.subviews) {
    //NSLog(@"%@", NSStringFromClass([subview class]));
    if ([subview isKindOfClass:NSClassFromString(@"UISearchDisplayControllerContainerView")])
    {
        CGRect frame = subview.frame;
        frame.origin.y += 10;
        subview.frame = frame;
    }
}

}

3: change the xib/storyboard Search Display Controller from UISearchDisplayController to MySearchController

回答2:

I thought the searchDisplayController owned a seperate tableview, so my guess is that you would need to resize that one.

Something along the lines of: <yourSearchViewController>.view.frame =self.tableView.frame;

or if you don't have it as class variable, in a method which receives it as argument, eg:

-(void)searchDisplayController:(UISearchDisplayController *)controller didShowSearchResultsTableView:(UITableView *)tableView {
   controller.view.frame = self.tableView.frame;
    tableView.backgroundColor = [UIColor colorWithRed:243.0/255.0 green:236.0/255.0 blue:212.0/255.0 alpha:1];   
}

Alternativily you might want to subclass it and override its view properties locally.

Hope this helps!

The UISearchDisplayController does owns its own tableview which not as easy to tame. I came across something like this and am still looking for a better solution.

-(void)searchDisplayControllerWillBeginSearch:(UISearchDisplayController *)controller
{
    [controller.searchResultsTableView setDelegate:self];   
    CGFloat gr = 12.0;
    controller.searchResultsTableView.backgroundColor = [UIColor colorWithRed:gr green:gr blue:gr alpha:0.0];
    [controller.searchResultsTableView setSeparatorStyle:UITableViewCellSelectionStyleNone];
    CGRect searchTableFrame = CGRectMake(7, 105, 305, 292);
    [controller.searchResultsTableView setFrame:searchTableFrame];
}

The above code does sets the background to transparent but seems to silently ignore the frame size.

EDIT:SOLVED I found the robust solution to this here. This saved my life.
