我有一个类似这样的JSON文件。
{
"Team Name" : "Team",
"Images" : "images",
"Players" : [
{
"Number" : "61",
"Height" : "6'5\"",
"Position" : "P",
"DOB" : "Feb 22, 1989",
"First Name" : "Chris",
"Weight" : "210",
"Last Name" : "Shmoe",
"Bats" : "R",
"Throws" : "R"
},
{
"Number" : "54",
"Height" : "6'3\"",
"Position" : "P",
"DOB" : "Dec 31, 1982",
"First Name" : "Ronald",
"Weight" : "240",
"Last Name" : "Peter",
"Bats" : "R",
"Throws" : "R"
},
{
"Number" : "67",
"Height" : "6'4\"",
"Position" : "P",
"DOB" : "Sep 24, 1984",
"First Name" : "Scott",
"Weight" : "215",
"Last Name" : "Tim",
"Bats" : "R",
"Throws" : "R"
},
这是我的内容。
var downloadFailed = false
var error: NSError? = nil
let navigationController = self.window!.rootViewController as! UINavigationController
let masterController = navigationController.childViewControllers[0] as! PlayerViewController
if let url = NSURL(string: " ") {
if let urlData = NSData(contentsOfURL: url) {
let jsonString = NSString(data: urlData, encoding: NSUTF8StringEncoding)
println(jsonString)
var result = NSJSONSerialization.JSONObjectWithData(urlData, options: NSJSONReadingOptions.allZeros, error: nil) as? NSDictionary
print("dictionary created")
if let players = result?.objectForKey("Players") as? [[String:AnyObject]]
{
for dictionary in players{
let fname = players["First Name"]
let lname = array["Players"]?["Last Name": String]
let number = array["Players"]?["Number"]
let position = array["Players"]?["Position"]
let bats = array["Players"]?["Bats"]?!.string
let throws = array["Players"]?["Throws"]?!.string
let height = array["Players"]?["Height"]?!.string
let weight = array["Players"]?["Weight"]?!.string
let DOB = array["Players"]?["DOB"]?!.string
masterController.objects.append(Players(fName: (fname as String?)!, lname: (lname as String?)!, position: (position as String?)!, bats: (bats as String?)!, throws: (throws as String?)!, height: (height as String?)!, weight: (weight as String?)!, DOB: (DOB as String?)!, number: (number as String?)!))}
目前我认为唯一不正确的是我不知道如何使代码正确读取,以便使用键“Players”并从JSON文件中读取正确的信息。
编辑:
我已经在努力解决问题,现在很少出现错误,只是没有停止崩溃。
if let dict = array as? [String: AnyObject]
但这是我新的加载数据函数代码:
但这是我的新的“加载数据”函数的代码:
func preloadData() {
var downloadFailed = false
var error: NSError? = nil
let navigationController = self.window!.rootViewController as! UINavigationController
let masterController = navigationController.childViewControllers[0] as! PlayerViewController
if let url = NSURL(string: "removed for reasons") {
if let urlData = NSData(contentsOfURL: url) {
if let array: AnyObject! = NSJSONSerialization.JSONObjectWithData(urlData, options: nil, error: &error)
{
print (array)
if let dict = array as? [String: AnyObject]
{
if let players = dict["Players"] as? [AnyObject]
{
for dictionary in players {
let fname = dictionary["First Name"]
let lname = dictionary["Last Name"]
let number = dictionary["Number"]
let position = dictionary["Position"]
let bats = dictionary["Bats"]
let throws = dictionary["Throws"]
let height = dictionary["Height"]
let weight = dictionary["Weight"]
let DOB = dictionary["DOB"]
masterController.objects.append(Players(fName: fname as! String, lname: lname as! String, position: position as! String, bats: bats as! String, throws: throws as! String, height: height as! String, weight: weight as! String, DOB: DOB as! String, number: number as! String))
}
}
}
//masterController.objects.sort({$0.courseNumber < $1.courseNumber})
}
else
{
downloadFailed = true
}
} else {
downloadFailed = true
}
} else {
downloadFailed = true
}
if downloadFailed {
let alert = UIAlertView(title: "Error", message: "Unable to download course data", delegate: nil, cancelButtonTitle: "OK")
alert.show()
}
}
