使用swift上传Firebase图像

Question

当我运行代码时，完成处理程序块不起作用。当线路工作mediaFolder.child(userId!).putData(data, metadata: nil) { (metadata, error) in图像文件上传到存储器中，但代码未在块中运行。这是我的代码：

if let data = self.profileImage.image?.jpegData(compressionQuality: 0.5)
{
mediaFolder.child(userId!).putData(data, metadata: nil) { (metadata, error) in
if error != nil {
// errror 
} 
else {
//enter code here 
}
}

请参阅下面的代码将图像数据上传到存储并获得下载url

var imgData: NSData = NSData(data: UIImageJPEGRepresentation((self.img_Photo?.image)!, 0.5)!)
self.uploadProfileImageToFirebase(data: imgData)
func uploadProfileImageToFirebase(data:NSData){
let randomPic = parentVC?.randomString(length: 10)
let storageRef = Storage.storage().reference().child("Profile_Pics").child("(userId ?? randomPic).jpg")
if data != nil {
storageRef.putData(data as Data, metadata: nil, completion: { (metadata, error) in
if(error != nil){
print(error)
return
}
guard let userID = Auth.auth().currentUser?.uid else {
return
}
// Fetch the download URL
storageRef.downloadURL { url, error in
if let error = error {
// Handle any errors
if(error != nil){
print(error)
return
}
} else {
// Get the download URL for 'images/stars.jpg'
let urlStr:String = (url?.absoluteString) ?? ""
print(urlStr)
}
}
})
}
