这是我打开相机的代码：

解决方法 使用以下代码获取从照片库中拍摄的图像并保存在照片库中.

Code Support for Swift 3.1 & 4.0 version:

首先,我们必须在Project的.pList文件中进行权限设置： –

1)相机

<key>NSCameraUsageDescription</key><string>This app will use camera.</string>

2)图片库

<key>NSPhotolibraryUsageDescription</key><string>You can select photos to attach to reports.</string>

3)保存到照片库

<key>NSPhotolibraryAddUsageDescription</key><string>Please allow access to save photo in your photo library</string>

我们需要打开.pilst文件作为源代码类型,然后在里面添加权限 –

Swift 4.2 Code update –
