Question

我正在尝试使用Firebase Storage记录的示例代码：

// Reference to an image file in Firebase Storage
let reference = storageRef.child("images/stars.jpg")

// UIImageView in your ViewController
let imageView: UIImageView = self.imageView

// Placeholder image
let placeholderImage = UIImage(named: "placeholder.jpg")

// Load the image using SDWebImage
imageView.sd_setImage(with: reference, placeholderImage: placeholderImage)

在我的应用中如此改编：

  func setImage(_ picid: Int32){

        let imagesRefs = Constants.FirebaseConfig.storageRef.child("images/thumbs/\(getuid())/thumb_\(picid).jpg");
        let placeholderImage = UIImage(named: "placeholder.jpg")

        profilePicIV.sd_setImage(with: imagesRefs, placeholderImage: placeholderImage)
}

但是xcode找不到方法sd_setImage所以我认为我必须使用pod'FirebaseUI / Storage'更新我的podfile但是在修改我的podfile后我得到了这个错误：

[!] Unable to satisfy the following requirements:

- `TwitterCore (~> 2.8.0)` required by `Podfile`
- `TwitterCore (>= 3.0.0)` required by `TwitterKit (3.0.0)`
- `FirebaseUI` required by `Podfile`

Specs satisfying the `FirebaseUI` dependency were found, but they required a higher minimum deployment target.

我的pods文件是这样的，虽然我尝试过其他pod组合，但效果相同或更差：

# Uncomment the next line to define a global platform for your project
platform :ios, '10.3'

# Comment the next line if you're not using Swift and don't want to use dynamic frameworks
use_frameworks!
  target 'StrengthStandards' do
    #Pods for StrengthStandards
    pod 'Firebase'
    pod 'Firebase/Core'
    #pod 'Firebase/Auth'
    #pod 'FirebaseUI/Google'
    #pod 'Firebase/Crash'
    #pod 'Firebase/RemoteConfig'
    pod 'FirebaseUI'
    pod 'Firebase/Database'
    #pod 'FirebaseUI/Database'
    #pod 'Firebase/Storage'
    pod 'FirebaseUI/Storage'
    pod 'TwitterCore', '~>2.8.0'

  target 'StrengthStandardsTests' do
    inherit! :search_paths
    # Pods for testing
  end

  target 'StrengthStandardsUITests' do
    inherit! :search_paths
    # Pods for testing
  end

end

我做错了什么？此外，我的xcode在No such module 'FirebaseAuthUI'行上显示错误import FirebaseAuthUI。

在此问题出现之前，我的Firebase数据库和Firebase Auth正在运行。

我在MacOS 10.12.6上使用Xcode 8.3.3和Swift 3

由于

PS：取得一些进展 - 现在我的podfile是：

# Uncomment the next line to define a global platform for your project
platform :ios, '10.3'

# Comment the next line if you're not using Swift and don't want to use dynamic frameworks

  target 'StrengthStandards' do
    use_frameworks!
    #Pods for StrengthStandards
    #pod 'Firebase'
    pod 'Firebase/Core'
    #pod 'Firebase/Auth'
    pod 'FirebaseUI/Auth'

    pod 'FirebaseUI/Google'
      #pod 'FirebaseUI/Google'
    #pod 'Firebase/Crash'
    #pod 'Firebase/RemoteConfig'
    #pod 'FirebaseUI'
      pod 'Firebase/Database'
      #pod 'FirebaseUI/Database'
    #pod 'Firebase/Storage'
    pod 'FirebaseUI/Storage'
    pod 'TwitterCore', '~>2.8.0'
  target 'StrengthStandardsTests' do
    inherit! :search_paths
    # Pods for testing
  end

  target 'StrengthStandardsUITests' do
    inherit! :search_paths
    # Pods for testing
  end

end

然而我不再得到依赖性问题，xcode现在告诉我方法调用

  profilePicIV.sd_setImage(with: imagesRefs, placeholderImage: placeholderImage)

错了：

/Users/myname/Dev/IOSDev/StrengthStandards/StrengthStandards/Settings.swift:325:40: Cannot convert value of type 'StorageReference' to expected argument type 'URL?'

现在似乎工作，但我承认我不确定它是否完全按照应该的方式完成。对于这里感兴趣的人，到目前为止我所拥有的是： Podfile：

# Uncomment the next line to define a global platform for your project
platform :ios, '10.3'

# Comment the next line if you're not using Swift and don't want to use dynamic frameworks

  target 'StrengthStandards' do
    use_frameworks!
    pod 'Firebase/Core'
    pod 'FirebaseUI/Auth'
    pod 'FirebaseUI/Google'
    pod 'Firebase/Database'
    pod 'FirebaseUI/Storage'
    pod 'TwitterCore', '~>2.8.0'
    pod 'SDWebImage/Core'
  target 'StrengthStandardsTests' do
    inherit! :search_paths
    # Pods for testing
  end

  target 'StrengthStandardsUITests' do
    inherit! :search_paths
    # Pods for testing
  end

end

这是我的功能：

import SDWebImage
func setImage(_ picid: Int32){

        let imagesRefs = Constants.FirebaseConfig.storageRef.child("images/thumbs/\(Constants.getUID())/thumb_\(picid).jpg");

        imagesRefs.downloadURL { url, error in
            if let error = error {
                // Handle any errors
                print("Error getting url for profile pic: \(error)")
            } else {
                // Get the download URL for 'images/stars.jpg'
                let placeholderImage = UIImage(named: "placeholder.jpg")
                self.profilePicIV.sd_setImage(with: url, placeholderImage: placeholderImage)
            }
        }
}

与Firebase的Cocoapods pod文件依赖性问题，特别是FirebaseUI
