我的.xml文件中确实需要此标头:
unsigned long currentVCIndex = [self.navigationController.viewControllers indexOfObject:self.navigationController.topViewController];
//previous view controller
UIViewController *view = (UIViewController *)[self.navigationController.viewControllers objectAtIndex:currentVCIndex - 1];
if([view isKindOfClass:[CustomViewController class]])
{
[self runSomething];
}
我无法根据需要创建文件,因为xmlwriter在我的所有尝试中都抛出了错误(尝试了整整一天以来我发现的所有内容)。
这里缺少什么-如何根据需要生成文件?
代码已截断:
<document xsi:schemaLocation="http://www.xxxxx.ch/schema/2.1
http://www.xxxxx.ch/schema/xxxxx_2.1.01.xsd"
xmlns="http://www.xxxxx.ch/schema/2.1"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
谢谢您的提示。

经过反复尝试,我自己找到了解决方案:
代码:
Dim cNameSpace As String = "http://www.xxxxx.ch/schema/2.1"
Dim cSchemaInstance As String = "http://www.w3.org/2001/XMLSchema-instance"
'
Using writer As XmlWriter = XmlWriter.Create(cFileExport, settings)
writer.WriteStartDocument()
writer.WriteStartElement("document", cNameSpace) ------
writer.WriteAttributeString("xmlns", "xsi", "http://www.w3.org/2000/xmlns/", cSchemaInstance)
writer.WriteAttributeString("xsi", "schemaLocation", cSchemaInstance, "http://www.xxxxx.ch/schema/2.1 http://www.xxxxx.ch/schema/xxxxx_2.1.01.xsd")
生成:
<document xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.xxxxx.ch/schema/2.1
http://www.xxxxx.ch/schema/eSchKG_2.1.01.xsd"
xmlns="http://www.xxxxx.ch/schema/2.1">
与示例中的顺序不完全相同,但这无关紧要...
现在,该文件已从系统中被确认为有效文件,我必须将该文件发送至该文件。
