Xcode 7 Warning – directory not found for option – iPhoneSimulator9.0.sdk

You need to do this:

1. Click on your project (targets)
2. Click on Build Settings
   • if your error includes the -L flag, then delete the values in Library Search Paths
   • if your error includes the -F flag, then delete the values in Framework Search Paths

And regarding the second error, sorry i can't help you out with that one. Hope someone else can help you out.

Just to clarify, I assume you're using OwnerDrawVariable style for your combobox. If I understood your question correctly, there are couple of ways to do what you need:

• Call RefreshItems method of the combobox which would recreate items and trigger onMeasureItem event for each item. This method is protected for the ComboBox class, so below is an example on how you could do it using reflection:

    MethodInfo method = comboBox1.GetType().GetMethod(
        "RefreshItems", BindingFlags.Instance | BindingFlags.NonPublic);
    if (method != null) method.Invoke(comboBox1, null);

• Send the CB_SETITEMHEIGHT message to the control with the new height of the item whenever you want to change it:

    public const int CB_SETITEMHEIGHT = 0x0153;
    [DllImport("user32.dll", CharSet = CharSet.Auto)]
    static extern IntPtr SendMessage(IntPtr hWnd, UInt32 Msg, int wParam, int lParam);
    ...
    // this will set height to 100 for the item with index 2 
    SendMessage(comboBox1.Handle, CB_SETITEMHEIGHT, 2, 100); 

Hope this helps, regards
