將表格視圖與細節視圖搜索

Question

我寫了一個代碼，它將數據輸入到tableView中並過濾用戶輸入的內容。我的問題是如何將每個tableView單元格推送到新的viewController或DetailView。

這是代碼。

#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",

        @"InvestorPlace Rank: Hold   AAPL : Apple", 
        @"Nasdaq Rank: Buy      AAPL : Apple", 
        @"Target Price: $135     AAPL : Apple",

從我個人理解，你想顯示有關新的UIViewController選擇的UITableViewCell細節。如果多數民衆贊成的話，那麼你需要使用

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

然後

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

希望這有助於。
