我正在尝试从动态 TableView 单元格(作为搜索结果表的一部分)链接到特定的 View Controller
到目前为止我实现的代码是:
SearchViewController.h
import <UIKit/UIKit.h>
@interface SearchViewController : UITableViewController <UISearchDisplayDelegate, UISearchDisplayDelegate>
@property (strong,nonatomic) NSArray *sysTArray;
@property (strong,nonatomic) NSMutableArray *filteredsysTArry;
@property IBOutlet UISearchBar *sysTSearchBar;
@end
SearchViewController.M
#import "SearchViewController.h"
#import "sysT.h"
@interface SearchViewController ()
@end
@implementation SearchViewController
@synthesize sysTArray;
@synthesize filteredsysTArry;
@synthesize sysTSearchBar;
- (id)initWithStyle:(UITableViewStyle)style
{
self = [super initWithStyle:style];
if (self) {
// Custom initialization
}
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
sysTArray = [NSArray arrayWithObjects:
[sysT sysTOfCategory:@"p" name:@"H1"],
[sysT sysTOfCategory:@"p" name:@"W2"],
[sysT sysTOfCategory:@"p" name:@"W3"],
[sysT sysTtOfCategory:@"p" name:@"C4"],
[sysT sysTOfCategory:@"c" name:@"O5"],
[sysT sysTOfCategory:@"c" name:@"C6"],
[sysT sysTOfCategory:@"a" name:@"L7"], nil];
self.filteredSysTArry = [NSMutableArray arrayWithCapacity:[sysTArray count]];
[self.tableView reloadData];
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
if (tableView == self.searchDisplayController.searchResultsTableView) {
return [filteredsysTArry count];
}else{
return [sysTArray count];
}
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
}
- (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];
}
SysT *sysT = nil;
if (tableView == self.searchDisplayController.searchResultsTableView) {
sysT = [filteredsysTArry objectAtIndex:indexPath.row];
}else{
sysT = [sysTArray objectAtIndex:indexPath.row];
}
cell.textLabel.text = sysT.name;
[cell setAccessoryType:UITableViewCellAccessoryDisclosureIndicator];
return cell;
}
#pragma mark Search Filtering
-(void)filterContentForSearchText:(NSString*) searchText scope:(NSString*)scope {
[self.filteredSysTArry removeAllObjects];
NSPredicate *predicate = [NSPredicate predicateWithFormat:@"SELF.name contains[c] %@", searchText];
filteredSysTArry = [NSMutableArray arrayWithArray:[sysTArray filteredArrayUsingPredicate:predicate]];
}
#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 scope:
[[self.searchDisplayController.searchBar scopeButtonTitles] objectAtIndex:searchOption]];
return YES;}
@end
如何根据动态单元格中的数据启动特定的 View Controller ?
更详细地说,如果用户搜索 H1,然后单击该动态单元格,我将如何显示相关的 H1 View Controller ?
正如您可能从我非常粗糙的代码中看出的那样,我正处于陡峭的学习曲线上。如果您能尽可能将您的答案作为婴儿证明,那就太棒了,并且真的会帮助我。 (此外,我正在使用 Storyboard)。
谢谢!
最佳答案
您需要实现 tableView:didSelectRowAtIndexPath: 当您选择一行时调用它。您可以使用传递给该方法的 indexPath 查询数据源来获取该行的数据。然后,您可以使用您需要的任何逻辑来选择下一个要转到的 View Controller 。您可以通过调用 performSegueWithIdentifier 来做到这一点。
