The "Cannot connect to iTunes Store" issue may be due to one or more of the following reasons:

• The sandbox may be unreachable. Check the System Status for the status of the iTunes Sandbox.
• Your app does not have a bundle version (CFBundleVersion). See Setting the Version Number and Build String for more information.
• Your app is running in the Simulator, which does not support in-app purchase.
• You are attempting to purchase a product that is unavailable for sale. See Query the App Store for product information before presenting your app’s store UI for more information.

經(jīng)過排查，發(fā)現(xiàn)項(xiàng)目雖然填寫了build值，但是plist文件的Bundle Version字段丟失了值。

填上對應(yīng)的數(shù)值后，再進(jìn)行測試，就沒有問題了。
