因此,我使用SwiftyJSON从API下载数据。我正在转换它,并循环以获得所有结果。我试图将每个结果的特定部分打印出来,但我似乎无法使其正常工作。
我在下面使用的代码接受json,并循环遍历它并打印出下面的内容。从印刷的内容来看,我只是想得到“主题”。
ListView
然后给出如下值:
do {
let jsonObj = try JSONSerialization.jsonObject(with: data, options: []) as! [String: AnyObject]
let json = JSON(jsonObj)
let pms: NSArray = json["result"]["pms"].arrayValue as NSArray
let arrayLength = pms.count
for var i in (0..<arrayLength) {
let pm = pms[i]
i+=1
}
} catch let error as NSError {
print(error)
}
如果我尝试类似
的话{
"subject" : "Example",
"status" : 1,
"recipient" : 012345,
"recipientusername" : "Example",
"dateline" : "2018-01-01",
"sender" : 012345,
"pmid" : 012345,
"senderusername" : "DoctorSheep"
}
{
"subject" : "Example 2",
"status" : 1,
"recipient" : 678910,
"recipientusername" : "Example 2",
"dateline" : "2018-01-01",
"sender" : 678910,
"pmid" : 678910,
"senderusername" : "Example 2"
}
我收到错误“类型'任何'没有下标成员”。
答案 0 :(得分:0)
let pms = json["result"]["pms"].arrayValue as Array
let arrayLength = pms.count
for var i in (0..<arrayLength) {
let pm = pms[i]
let subject = pm["subject"]
print(subject)
i+=1
}
