如何检查iOS设备中的Facetime支持(硬件检查)

问题描述

我想检查我使用的iOS设备是否支持Facetime通话.我不想检查设备上的iOS版本，而是要检查设备是否具有发起Facetime通话的硬件支持.

I want to check if iOS device I am using has support for Facetime call. I don't want to check the iOS version on the device, rather if the device has the hardware support to initiate a Facetime call.

例如:我有一台iOS 1和更高版本的iPad 1，但没有摄像头(或前置摄像头)的iOS 4.0，则不应启动Facetime通话.我该怎么办?

For example: I have an iPad 1 with iOS version 4.0 and above, but if I don't have a camera (or a front camera), the Facetime call should not initiate. How can I do this?

推荐答案

尝试通过FaceTime方案使用canOpenUrl方法，如下所示:

Try using canOpenUrl method with FaceTime scheme, as follows:

[[UIApplication sharedApplication] canOpenURL: [NSURL URLWithString: @"facetime://5555555555"]];
