我正在尝试设置我的searchBar.text,当我从视图1推出视图2.我正在将一个字符串成功传递到视图2但是我想将字符串设置为searchBar.text来过滤我的表。这是我的代码到目前为止,但似乎没有工作。
- (void)viewDidLoad
{
[super viewDidLoad];
self.title = NSLocalizedString(@"Places", nil);
self.managedObjectContext = [self getContext];
UIBarButtonItem * sortButton = [[UIBarButtonItem alloc] initWithTitle:@"Sort" style:UIBarButtonItemStyleBordered target:self action:@selector(sort)];
self.navigationItem.rightBarButtonItem = sortButton;
[sortButton release];
//HIT WS TO SEE LAST UPDATED AND COMPARE TO STORED LAST UPDATED DATE
//IF WS HAS NEWER DATE,BLOW CD AWAY AND CALL getRSSDAta
self.searchBar.delegate = self;
self.title = @"Results";
self.navigationController.navigationBarHidden = NO;
__tableView.delegate = self;
__tableView.dataSource = self;
searchedData = [[NSMutableArray alloc]init];
tableData = [[NSMutableArray alloc]init];
[tableData addObjectsFromArray:_PlaceArray];//on launch it should display all the records
[recurringArray initWithObjects:@"Alphabetical",@"Rating Low to High", @"Rating Hight to Low", nil];
UIColor *background = [[UIColor alloc] initWithPatternImage:[UIImage imageNamed:@"background_texture.png"]];
self.view.backgroundColor = background;
[background release];
recurringDate = [[UIPickerView alloc] initWithFrame:CGRectMake(0, 190, 320, 200)];
recurringDate.showsSelectionIndicator = YES;
recurringDate.delegate = self;
[recurringDate selectRow:0 inComponent:0 animated:YES];
[self.view addSubview:recurringDate];
recurringDate.hidden = YES;
NSLog(@"search text is %@", self.search);
searchBar.text = self.search;
[self searchBarSearchButtonClicked:searchBar];
}
- (void)searchBarTextDidBeginEditing:(UISearchBar *)searchBar
{
// only show the status bar’s cancel button while in edit mode
useSearchData = YES;
self.searchBar.showsCancelButton = YES;
self.searchBar.autocorrectionType = UITextAutocorrectionTypeNo;
// flush the previous search content
[tableData removeAllObjects];
}
- (void)searchBarTextDidEndEditing:(UISearchBar *)searchBar
{
self.searchBar.showsCancelButton = NO;
}
- (void)searchBar:(UISearchBar *)searchBar textDidChange:(NSString *)searchText
{
if([searchText isEqualToString:@""] && [__searchBar.text isEqualToString:@""]){ //if nothing is in the search bar show normal table
useSearchData = NO;
[self.tableView reloadData];
[self.searchBar resignFirstResponder];
return;
}
else
{
searchText = __searchBar.text;
useSearchData=YES;
NSPredicate * p = [NSPredicate predicateWithFormat:@"name contains[cd] %@",searchText]; //comparing stored locations to searchText
self.searchResults = [CoreDataBasicService fetchResultsForEnity:@"Place" WithPredicate:p andSortDiscriptor:@"name" Ascending:YES];
[self.tableView reloadData];
}
}
- (void)searchBarCancelButtonClicked:(UISearchBar *)searchBar
{
useSearchData = NO;
[self.searchResults removeAllObjects];
[self.tableView reloadData];
[self.searchBar resignFirstResponder];
self.searchBar.text = @"";
}
-(void)searchBarSearchButtonClicked:(UISearchBar *)_searchBar
{
[searchBar resignFirstResponder];
}
答案 0 :(得分:0)
可能听起来很傻,但要确保你把它连接到IB,我忘了在我干扰某些代码时这样做
