Question

我编写了一个代码，可以将数据输入到tableView中，并过滤用户键入的内容。我的问题是如何将每个tableView单元格推送到新的viewController或DetailView。

这是代码。

#import "SearchBar.h"

@interface SearchBar ()

@end

@implementation SearchBar

{
NSMutableArray *totalStrings;
NSMutableArray *filteredStrings;
BOOL isFiltered;
}

- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view.

{
    self.mySearchBar.delegate = self;
    self.myTableView.delegate = self;
    self.myTableView.dataSource = self;

    totalStrings = [[NSMutableArray alloc]initWithObjects:


                    @"Apple - AAPL - Buy", @"Zacks Rank: Hold                        AAPL : Apple",
                    @"The Street Rank: Buy                AAPL : Apple",

据我所知，您希望显示有关在新UIViewcontroller上选择的UItableviewcell的详细信息。如果是这样，那么你需要使用

- (void)tableView:(UITableView *)tableView accessoryButtonTappedForRowWithIndexPath:(NSIndexPath *)indexPath{
[self performSegueWithIdentifier:@"yourSegueNameHere" sender:self];
}

然后

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
if ([segue.identifier isEqualToString:@"yourSegueNameHere"]){
//pass the data to the ViewController
}
}

希望这有帮助。

使用搜索将表视图单元格推送到详细信息视图
