UISearchDisplayController "shouldReloadTableForSearchString return NO" reloads table
Why does my UISearchDisplayController show "No results" even if the shouldReloadTableForSearchString method returns NO? Shouldn't it just do nothing and stay black? How can I prevent it from doing so?
#import "RootViewController.h"
@implementation RootViewController
#pragma mark Table view methods
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return 1;
}
// Customize the number of rows in the table view.
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
if (tableView == self.searchDisplayController.searchResultsTableView) {
return 0;
}
return 10;
}
// Customize the appearance of table view cells.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
}
// Configure the cell.
cell.textLabel.text = [NSString stringWithFormat:@"row %d", indexPath.row];
return cell;
}
#pragma mark SearchController stuff
- (BOOL)searchDisplayController:(UISearchDisplay开发者_JAVA技巧Controller *)controller shouldReloadTableForSearchString:(NSString *)searchString {
return NO;
}
- (void)dealloc {
[super dealloc];
}
@end
No, tableViews (including the searchTableView
created by a UISearchDisplayController
) automatically load data when they are displayed. The shouldReloadTableForSearchString:
method will prevent the table from reloading only as characters are typed into the search box.
See my answer to UISearchDisplayContoller – can't prevent table reload on typing in search bar for suggestions on how to deal with this.
