Question

这是我的问题。

我似乎无法弄清楚如何访问＆＃34;详细信息＆＃34;键入与＆＃34;名称＆＃34;相同的级别;密钥一旦搜索特定的名称密钥。也许我错过了什么？

我知道你可以得到＆＃34;细节＆＃34;通过private void btnUpload_Click(object sender, EventArgs e) { DataTable dt = new DataTable(); string strSelect = "SELECT serial, upc, man_date, location, product, created_by, created_date, serial from schema.table where rownum < 2"; string strInsert = "INSERT INTO schema.table (serial, upc, man_date, location, product, created_by, created_date, serial) VALUES (:serial, :upc, :man_date, :location, :product, :created_by, :created_date, :serial)"; string conStr = ConfigurationManager.ConnectionStrings["connection"].ConnectionString; OracleConnection connection = new OracleConnection(conStr); connection.Open(); if (connection.State != ConnectionState.Open) { return; } OracleDataAdapter adapter = new OracleDataAdapter(strSelect, conStr); OracleCommandBuilder builder = new OracleCommandBuilder(adapter); adapter.Fill(dt); dt.Columns["SERIAL"].Unique = true; dt.Merge(dtUpload); dt.Rows.Remove(dt.Rows[0]); foreach (DataRow row in dt.Rows) { row.SetAdded(); } try { adapter.Update(dt); } catch (Exception ex) { string x = ex.Message + ex.StackTrace; throw; } finally { connection.Close(); connection.Dispose(); } }，但我不确定如何获得与搜索到的相同级别的那个。

代码：

[dict objectForKey:@"Details"]

plist中：

- (IBAction)ScoringButtonView:(id)sender {
    ScoringViewController *svController = [[ScoringViewController alloc] initWithNibName:@"ScoringView" bundle:[NSBundle mainBundle]];
    [self.navigationController pushViewController:svController animated:YES];

    UIButton *scoringButton = (UIButton*)sender;
    NSLog(@"Scoring is %@ ", scoringButton.currentTitle);
    svController.ScoringName = scoringButton.currentTitle;
    NSString *path = [[NSBundle mainBundle] pathForResource:@"Scoring" ofType:@"plist"];
    NSArray *plistData = [NSArray arrayWithContentsOfFile:path];
    for (NSDictionary *dict in plistData) {
        if ([[dict objectForKey:@"Name"] isEqualToString:scoringButton.currentTitle]) {
            NSLog(@"Scoring ==  %@ ", scoringButton.currentTitle);
//            svController.ScoringInfo = 
        }
    }

我不确定是什么混淆。您已经知道如何获取Name密钥的值。获取Details密钥的值是相同的：

for (NSDictionary *dict in plistData) {
    if ([dict[@"Name"] isEqualToString:scoringButton.currentTitle]) {
        NSString *details = dict[@"Details"];
    }
}

请注意我是如何使用现代Objective-C语法而不是使用objectForKey:的旧样式。

//此方法应该可以正常工作

//枚举方法优于循环

  NSString *filePath = [[NSBundle mainBundle] pathForResource:@“LanguageList” ofType:@"json"];
    NSString *myJSON = [[NSString alloc] initWithContentsOfFile:filePath encoding:NSJSONReadingAllowFragments error:NULL];
    NSError *error =  nil;
    NSDictionary * dict = [NSJSONSerialization JSONObjectWithData:[myJSON dataUsingEncoding:NSUTF8StringEncoding] options:kNilOptions error:&error];


   [dict[@"result"] enumerateObjectsUsingBlock:^(id  _Nonnull objList, NSUInteger idx, BOOL * _Nonnull stop) {

            NSLog(@“Values %@”,obj);
            *stop = YES;

        }
    }];

从objective-c获取plist文件的详细信息
