我有一个UITableView,它有一个搜索栏,搜索栏可以使用,但结果不会链接到我的详细信息视图。代码如下:
#import "firstTableViewController.h"
#import "detailViewCell.h"
#import "DetailViewController.h"
@interface firstTableViewController ()
@end
@implementation firstTableViewController
@synthesize craftingItems1;
@synthesize bigImages;
@synthesize theText;
@synthesize searchDisplayController;
@synthesize searchResults;
- (id)initWithStyle:(UITableViewStyle)style
{
self = [super initWithStyle:style];
if (self) {
// Custom initialization
}
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
self.craftingItems1 = [[NSArray alloc] initWithObjects:
@"Item 1",
@"Item 2",
@"Item 3",
@"Item 4",
@"Item 5", nil];
self.theText = [[NSArray alloc] initWithObjects:
@"Description 1",
@"Description 2",
@"Description 3",
@"Description 4",
@"Description 4", nil];
self.bigImages = [[NSArray alloc] initWithObjects:
@"Image 1.png",
@"Image 2.png",
@"Image 3.png",
@"Image 4.png",
@"Image 5.png", nil];
}
- (void)viewDidUnload
{
[super viewDidUnload];
// Release any retained subviews of the main view.
// e.g. self.myOutlet = nil;
}
- (BOOL)shouldAutorotateToInterfaceOrientation: (UIInterfaceOrientation)interfaceOrientation
{
return (interfaceOrientation == UIInterfaceOrientationPortrait);
}
#pragma mark - Table view data source
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
// Return the number of sections.
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection: (NSInteger)section
{
// Return the number of rows in the section.
NSInteger rows = 0;
if ([tableView
isEqual:self.searchDisplayController.searchResultsTableView]){
rows = [self.searchResults count];
}
else{
rows = [self.craftingItems1 count];
}
return rows;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = @"tableCell";
UITableViewCell *cell = [tableView
dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc]
initWithStyle:UITableViewCellStyleDefault
reuseIdentifier:CellIdentifier];
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
}
/* Configure the cell. */
if ([tableView isEqual:self.searchDisplayController.searchResultsTableView]){
cell.textLabel.text =
[self.searchResults objectAtIndex:indexPath.row];
}
else{
cell.textLabel.text =
[self.craftingItems1 objectAtIndex:indexPath.row];
}
return cell;
}
// Configure the cell...
-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
if ([[segue identifier] isEqualToString:@"ShowCrafting"])
{
DetailViewController *theDetailViewController =
[segue destinationViewController];
NSIndexPath *myIndexPath = [self.tableView
indexPathForSelectedRow];
theDetailViewController.craftingModel = [[NSArray alloc]
initWithObjects: [self.craftingItems1
objectAtIndex:[myIndexPath row]],
[self.theText objectAtIndex: [myIndexPath row]],
[self.bigImages objectAtIndex:[myIndexPath row]],
nil];
}
}
- (void)filterContentForSearchText:(NSString*)searchText
scope:(NSString*)scope
{
NSPredicate *resultPredicate = [NSPredicate
predicateWithFormat:@"SELF contains[cd] %@",
searchText];
self.searchResults = [self.craftingItems1 filteredArrayUsingPredicate:resultPredicate];
}
#pragma mark - UISearchDisplayController delegate methods
-(BOOL)searchDisplayController:(UISearchDisplayController *)controller
shouldReloadTableForSearchString:(NSString *)searchString
{
[self filterContentForSearchText:searchString
scope:[[self.searchDisplayController.searchBar scopeButtonTitles]
objectAtIndex: [self.searchDisplayController.searchBar
selectedScopeButtonIndex]]];
return YES;
}
- (BOOL)searchDisplayController:(UISearchDisplayController *)controller
shouldReloadTableForSearchScope:(NSInteger)searchOption
{
[self filterContentForSearchText:[self.searchDisplayController.searchBar text]

return YES;
}
@end
详细视图与表格一起正常工作,但在使用搜索时,项目列表不会链接到详细信息视图。
