问题描述
我正在使用下面的代码使用用户名，密码和个人资料图片来注册用户.
I am using the code below to sign up a user with username, password, and a profile picture.
func createUserwithAllFields() {
let profileImageData = UIImageJPEGRepresentation(profileAvatar.image, 0.6)
//let profileImageData = UIImageJPEGRepresentation(profileImg, 0.6)
let profileImageFile = PFFile(data: profileImageData)
if tv_username.text != ""
&& tv_password.text != ""
{
var user = PFUser()
user.username = tv_username.text
user.password = tv_password.text
user["profileImage"] = profileImageFile
user.signUpInBackgroundWithBlock({ (success, error) -> Void in
if error == nil {
//if SignUp is successful
let installation = PFInstallation.currentInstallation()
installation["user"] = user
installation.saveInBackgroundWithBlock(nil)
//self.showChatOverview()
self.goToMainScreen()
} else {
}
})
}else{
}
}
当我在parse.com上查看他的User类时，有一个文件已上传(请参见下面的屏幕截图)
When I look at he User class on parse.com there is a file that get's uploaded (see screenshot below)
尽管有一个文件，但是当我单击并下载它时，我将其打开以查找空白(即白色)图像.
Although there is a file, when I click on it and download it, I open it to find a blank (i.e. white) image.
profileAvatar是ViewController中的UIImageView，它确实指向有效的图像，因为运行应用程序时我可以看到它.
The profileAvatar is a UIImageView in the ViewController and it does point to a valid image because I can see that when I run the app.
这是我看到的空白图片:
This is the blank image that I see:
推荐答案
在解析中，您需要先保存用户，然后保存图像，然后修改代码以实现以下目的:
In parse you need to first save the user and after save the image, I modify your code to accomplish that:
func createUserwithAllFields() {
let profileImageData = UIImageJPEGRepresentation(profileAvatar.image, 0.6)
let profileImageFile = PFFile(data: profileImageData)
if tv_username.text != "" && tv_password.text != "" {
var user = PFUser()
user.username = tv_username.text
user.password = tv_password.text
user.signUpInBackgroundWithBlock({ (success, error) -> Void in
if error == nil {
/println("SignUp is successful")
user["profileImage"] = profileImageFile
user.signUpInBackgroundWithBlock({ (success, error) -> Void in
if error == nil {
println("Image Saved")
} else {
println("Fail to Save Image")
}
)}
} else {
println("Fail to Sign up")
}
})
}else{
println("Invalid username and password")
}
}
