iOS(Swift3)中添加通讯录、添加图片到图库、添加视频到图库

1. 添加通讯录联系人

/**
 添加联系人
 */
+ (void)addContact:(CNContact *)contact {
    // 创建联系人请求
    CNSaveRequest *saveRequest = [[CNSaveRequest alloc] init];
    
    [saveRequest addContact:[contact mutableCopy] toContainerWithIdentifier:nil];
    // 写入联系人
    CNContactStore *store = [[CNContactStore alloc] init];
    [store executeSaveRequest:saveRequest error:nil];
}
           

2. 添加图片到图库中

let image = UIImage.init(data: successObject as! Data)!
                PHPhotoLibrary.shared().performChanges({
                    PHAssetChangeRequest.creationRequestForAsset(from: image)
                }, completionHandler: { (isCompleted, error) in
                    if error != nil {
                        myPrint(message: "image save error")
                    }
                })
           

3. 添加视频到图库中

PHPhotoLibrary.shared().performChanges({
                    PHAssetChangeRequest.creationRequestForAssetFromVideo(atFileURL: successObject as! URL)
                }, completionHandler: { (isCompleted, error) in
                    if error != nil {
                        myPrint(message: "video save error")
                    }
                })
