    }]
}, {
    "EventDate": "2015-02-20",
    "PubEvents": [{
        "Title": "Pat Kelly",
        "Description": "Pat Kelly from Ireland has extensive experience in entertaining all nationalities, as he has travelled around the world from New York to Amsterdam.

    }],
    "Matches": []
},

格式为：

的事件数组

var eventDate : String?
var pubEvents : Array<PubEvent>?
var matches : Array<Match>?

numberOfSectionsInTableView是eventarray.count，因为每个日期都是不同的

我正在努力使用numberOfRowsInSection。它应该是

self.eventarray[section].pubEvents?.count or self.eventarray[section].matches?.count

取决于哪个具有最高计数。

这是我第一次尝试做Swift，我很欣赏正确的方向。我试过这个：

func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        var returncount : Int = 1
        if let pubeventscount = self.eventarray[section].pubEvents?.count{
            if let sportscount = self.eventarray[section].matches?.count{
                if pubeventscount > sportscount{
                    returncount = pubeventscount
                }
                else{
                    returncount = sportscount
                }
            }
        }
        return returncount

    }

但没有结果

Answer 1

我不知道“没有结果”是什么意思，但是。

您的功能可以简化为：

func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    let event = self.eventarray[section]
    let matchesCount = event.matches?.count ?? 0
    let pubEventsCount = event.pubEvents?.count ?? 0
    return max(matchesCount, pubEventsCount, 1)
}

numberofRowsInSection有2个计数
