问题描述
我最近使用开发人员测试版在 Xcode 8 中更新到 Swift 3.我正在尝试实施 Firebase 身份验证,一切顺利.
I've recently updated to Swift 3 in Xcode 8 using the developer beta.I'm trying to implement Firebase Auth, and everything's going well.
我的问题:
我正在尝试将图片作为用户的个人资料图片上传到 Firebase 数据库.
I'm trying to upload an image as a user's profile picture to a Firebase database.
我以为我可以使用 UIImagePickerController
来做到这一点,但是当我这样做时,我得到了一个
I thought I could use the UIImagePickerController
to do this, but when I do, I get a
"线程 7:信号 SIGABRT
我知道这通常表示什么,但我检查过,当我点击它时,我的图像确实打印了我的测试语句.
I know what this would normally indicate, but I checked, and my image does indeed print my test statement when I tap it.
我失败的方法:
ViewController.swift
ViewController.swift
import UIKit
import Firebase
import Photos
class ViewController: UIViewController, UITextFieldDelegate, UIImagePickerControllerDelegate, UINavigationControllerDelegate{
@IBOutlet weak var imageView: UIImageView!
@IBOutlet var emailTextField: UITextField!
@IBOutlet var passWordTextField: UITextField!
@IBOutlet var nameTextField: UITextField!
override func viewDidLoad() {
super.viewDidLoad()
if FIRAuth.auth()?.currentUser?.uid != nil {
let storyboard = UIStoryboard(name: "Main", bundle: nil)
let view = storyboard.instantiateViewController(withIdentifier: "ProfileViewController")
self.present(view, animated: true, completion: nil)
}
imageView.addGestureRecognizer(UITapGestureRecognizer(target: self, action: #selector(handleSelectProfileImageView)))
imageView.isUserInteractionEnabled = true
self.emailTextField.delegate = self;
self.passWordTextField.delegate = self;
self.nameTextField.delegate = self;
}
func handleSelectProfileImageView() {
let picker = UIImagePickerController()
picker.delegate = self
picker.allowsEditing = true
present(picker, animated: true, completion: nil)
}
我不确定这是否只是 Swift 3 和开发人员 Xcode 8 beta 的问题,或者我是否只是为 swift 3 做错了.
I'm not sure yet if this is just a problem with Swift 3 and the developer Xcode 8 beta, or if I'm just doing it the wrong way for swift 3.
我正在使用 xcode8 的 GM 版本,但仍然遇到同样的错误.
I'm using the GM Version of xcode8, but still get that same error.
推荐答案
我认为您需要在 info.plist
中为相机和照片库添加 privacy - key
文件来自 xcode 8
.例如,
I think you need to add privacy - key
for camara and photo library in your info.plist
file as from xcode 8
. for example,
Key : Privacy - Media Library Usage Description
Value : YES
Key : Privacy - Photo Library Usage Description
Value : YES
Key : Privacy - Camara Usage Description
Value : YES
这里的值是 string
而不是 Boolean
.
here value is string
not Boolean
.
所以试试这个.
