[英]How to get variable outside of IF statement in init Swift
If I set the variable inside the if statement when I try to access the variable outside on the init I get the error "Instance member 'friendcomparison' cannot be used on type 'User'". 如果我尝试在init外部访问变量时在if语句中设置变量,则会收到错误消息“实例成员'friendcomparison'不能用于'User'类型”。 Any help would be appreciated, thank you.
任何帮助,将不胜感激,谢谢。
let friendcomparison: String
func getfriendname() {
if frienddeeper == Auth.auth().currentUser?.uid {
let friendcomparison = "yes"
}
let link = URL.init(string: credentials["profilePicLink"]!)
URLSession.shared.dataTask(with: link!, completionHandler: { (data, response, error) in
if error == nil {
let profilePic = UIImage.init(data: data!)
let user = User.init(name: name, username: username, email: email, id: id, friendstatus: friendcomparison, token: token!, profilePic: profilePic!)
completion(user)
}
}
func getfriendname() {
if frienddeeper == Auth.auth().currentUser?.uid {
friendcomparison = "yes"
}
let link = URL.init(string: credentials["profilePicLink"]!)
URLSession.shared.dataTask(with: link!, completionHandler: { [weak self] (data, response, error) in
if error == nil {
let profilePic = UIImage.init(data: data!)
let friendcomparison = self?.friendcomparison
let user = User.init(name: name, username: username, email: email, id: id, friendstatus: friendcomparison, token: token!, profilePic: profilePic!)
completion(user)
}
}
Just remove let
from let friendcomparison = "yes"
只需从
let friendcomparison = "yes"
删除let
and use [weak self]
with let friendcomparison = self?.friendcomparison
并使用
let friendcomparison = self?.friendcomparison
[weak self]
