我試圖設置我的searchBar.text當我從視圖1太視圖2.我傳遞一個字符串到視圖2成功但是我想設置字符串爲searchBar.text過濾我的表格。這是我的代碼到目前爲止,但似乎沒有工作。設置searchBar.text在視圖中加載
- (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];
}
搜索工具已經被過濾原始表干擾。我只想在第一個視圖中設置搜索文本,並將該字符串推送到第二個視圖中的searchBar。字符串傳遞正常我似乎不能設置searchBar文本字符串self.search。 – Bradley
