iOS Development-version Difference record

question one: The view location of the details page in the project is 64pt lower in iOS 7 and later.

Reason:

Because the system does not automatically take into account the height of the status bar and the navigation bar when you set the y of frame before iOS 6, but iOS 7 and later, the system will automatically take into account, so you have to consider this difference when you set the y of the frame.

question two: The project itself customized alert popup, causing alert cannot exit, so that the program stays on the alert page.

Reason:

IOS 7 and later versions, no custom alert is allowed.
