我已经创建了一些自定义UIView，并在我的项目中的另一个UIView中实现了。
我在调用某些函数或为某些对象设置值时崩溃，但在设置属性时却没有崩溃。
请参考下面的代码以正确理解代码并提出问题。
class SearchProfileDetailView: UIView {
@IBOutlet weak var userInfoTable: UITableView!
var userObject: UserObject?
override init(frame:CGRect) {
super.init(frame: frame)
loadViewFromNib()
}
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
loadViewFromNib()
}
func loadViewFromNib() {
let bundle = Bundle(for: type(of: self))
let nib = UINib(nibName: "SearchProfileDetailView", bundle: bundle)
let view = nib.instantiate(withOwner: self, options: nil)[0] as! UIView
view.frame = bounds
self.addSubview(view);
}
func setColor() {
self.backgroundColor = UIColor.red
}
}
我已在另一个UIView中将此SearchProfileDetailView与接口构建器和分配的插座一起使用，请参见下面的代码。
class SearchResultView: UIView {
@IBOutlet weak var profileDetailView: SearchProfileDetailView!
var currentIndex: Int?
override init(frame:CGRect) {
super.init(frame: frame)
loadViewFromNib()
}
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
loadViewFromNib()
}
func loadViewFromNib() {
let bundle = Bundle(for: type(of: self))
let nib = UINib(nibName: "SearchResultView", bundle: bundle)
let view = nib.instantiate(withOwner: self, options: nil)[0] as! UIView
view.frame = bounds
self.addSubview(view);
}
func setUserProfile(userObject: UserObject) {
profileDetailView.backgroundColor = UIColor.red // Not Crashed
profileDetailView.userObject = userObject //Crashed with error mentioned in title of question
profileDetailView.setColor() ////Crashed with error mentioned in title of question
}
}
调用profileDetailView.setColor（）和时崩溃
profileDetailView.userObject = userObject但未崩溃
profileDetailView.backgroundColor = UIColor.red
现在，我已通过接口构建器将此SearchResultView用于UIViewController。
class ExploreViewController: UIViewController {
@IBOutlet weak var searchResultView: SearchResultView!
func getResult() {
SearchAPIHandler().search(params: parameters) {[weak self] (responseData) in
DispatchQueue.main.async {
guard let strongSelf = self else {
return
}
if let users = responseData.users, !users.isEmpty {
strongSelf.searchResultView.setUserProfile(userObject: users[0])
}
}
}
}
最佳答案
我已经尝试了很多，现在我已经知道问题出在我的界面生成器上。
没有模块。
我检查了从目标继承模块，一切正常。
