我正在尝试为自定义集合视图单元格的某些组件分配值。该数组与自定义集合视图单元格位于同一类中,但是我无法缝隙访问该数组。任何意见,将不胜感激。
import UIKit
import CoreLocation
class eventCell: UICollectionViewCell {
@IBOutlet private weak var eventTitle: UILabel!
@IBOutlet private weak var descriptionLabel:UILabel!
@IBOutlet private weak var eventImage: UIImageView!
var eventArray = [(title:String, location:String, lat:CLLocationDegrees, long:CLLocationDegrees)]()
override func prepareForReuse() {
eventImage.image = nil
}
func lool() {
eventTitle.text = eventArray.title
}
}
但是,当我尝试添加标题时,仍然出现此错误:
类型'[((标题:字符串,位置:字符串,纬度:CLLocationDegrees),长:CLLocationDegrees)]]'的值(又名'Array <(title:字符串,位置:字符串,lat:双精度,长:双精度)> ')没有成员“标题”
任何帮助都会很棒,在此先感谢!

您应该执行以下操作:
class eventCell: UICollectionViewCell {
@IBOutlet private weak var eventTitle: UILabel!
@IBOutlet private weak var descriptionLabel:UILabel!
@IBOutlet private weak var eventImage: UIImageView!
typealias Event = (title:String, location:String, lat:CLLocationDegrees, long:CLLocationDegrees)
var eventArray = [Event]()
override func prepareForReuse() {
eventImage.image = nil
}
func lool() {
var event = Event(title: "a", location:"b", lat:5, long:4)
eventArray.append(event)
eventTitle.text = eventArray[0].title
}
}

为什么不创建一些Struct
?
像这样简单:
struct Event {
var title: String
var location: String
var lat: CLLocationDegrees
var long: CLLocationDegrees
}
然后执行以下操作:
var eventArray = [Event]()
并这样称呼它:
for event in eventArray{
event.title = eventTitle.text
}
