当我使用alertView下面的代码时，它会向我显示警告

warning: Semantic Issue: Method '-addTextFieldWithValue:label:' not found (return type defaults to 'id')

这是代码：

    UIAlertView *alSave=[[UIAlertView alloc]initWithTitle:@"Save as" message:@"Title the note and click Save" delegate:self cancelButtonTitle:@"save" otherButtonTitles:@"cancel", nil];
    NSArray *arr=[noteObj.noteTitle componentsSeparatedByString:@" - "];
    app.longClickId = [noteObj.noteId integerValue];
    [alSave addTextFieldWithValue:[NSString stringWithFormat:@"%@",[arr objectAtIndex:0]] label:@"Note Name"];
   // show me warning at this place

    textField = [alSave textFieldAtIndex:0];
    textField.keyboardType = UIKeyboardTypeAlphabet;
    textField.keyboardAppearance = UIKeyboardAppearanceAlert;
    textField.autocorrectionType = UITextAutocorrectionTypeNo;   // correction automatically

    [alSave show];
    if (app.NotePopOver!= nil) {
        [app.NotePopOver dismissPopoverAnimated:YES];

    }
    [alSave release];

如果您使用私有方法（其中addTextFieldWithValue:之一），那么 Apple 很可能会拒绝您的应用程序。您可以使用以下代码段获得相同的结果，由this answer提供，该链接归功于不再工作的链接：

UIAlertView *myAlertView = [[UIAlertView alloc] initWithTitle:@"Your title here!" message:@"this gets covered" delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"OK", nil];
UITextField *myTextField = [[UITextField alloc] initWithFrame:CGRectMake(12.0, 45.0, 260.0, 25.0)];
[myTextField setBackgroundColor:[UIColor whiteColor]];
[myAlertView addSubview:myTextField];
CGAffineTransform myTransform = CGAffineTransformMakeTranslation(0.0, 130.0);
[myAlertView setTransform:myTransform];
[myAlertView show];
[myAlertView release];

该方法未记录在案。您必须创建自己的文本字段，然后将其添加到警报视图。
