CLGeocoder：美国各州名称以短代码形式出现

Question

我正在使用 iOS 8.0 开发应用程序。

通过下面的链接，我正在分配位置对象， How can I get current location from user in iOS

我的目标是通过当前位置找出城市、州和国家/地区的名称。 使用此链接的答案，我得到了 Apple 地理编码器中使用的地标对象。 Get current city and country from CLGeocoder?

我一切都好，只是

当我得到 Country United States 的州名时。 它给了我简码，而不是给我完整的州名。

例如对于Alaska，它给了我AK 对于Alabama，它给了我AL

就像这是我的日志，

 North Kingstown, RI, United States

我想要完整的州名，因为我想在我的项目中使用完整的州名。

我通过此代码获取州名，

 NSString *stateName=myPlacemark.administrativeArea;

@Arpit B Parekh 有 Swift 3 版本的答案：

let stateCodes = ["AL","AK","AZ","AR","CA","CO","CT","DE","DC","FL","GA","HI","ID","IL","IN","IA","KS","KY","LA","ME","MD","MA","MI","MN","MS","MO","MT","NE","NV","NH","NJ","NM","NY","NC","ND","OH","OK","OR","PA","RI","SC","SD","TN","TX","UT","VT","VA","WA","WV","WI","WY"]
let fullStateNames = ["Alabama","Alaska","Arizona","Arkansas","California","Colorado","Connecticut","Delaware","District of Columbia","Florida","Georgia","Hawaii","Idaho","Illinois","Indiana","Iowa","Kansas","Kentucky","Louisiana","Maine","Maryland","Massachusetts","Michigan","Minnesota","Mississippi","Missouri","Montana","Nebraska","Nevada","New Hampshire","New Jersey","New Mexico","New York","North Carolina","North Dakota","Ohio","Oklahoma","Oregon","Pennsylvania","Rhode Island","South Carolina","South Dakota","Tennessee","Texas","Utah","Vermont","Virginia","Washington","West Virginia","Wisconsin","Wyoming"]

func shortStateName(_ state:String) -> String {
    let lowercaseNames = fullStateNames.map { $0.lowercased() }
    let dic = NSDictionary(objects: stateCodes, forKeys: lowercaseNames as [NSCopying])
    return dic.object(forKey:state.lowercased()) as? String ?? state}

func longStateName(_ stateCode:String) -> String {
    let dic = NSDictionary(objects: fullStateNames, forKeys:stateCodes as [NSCopying])
    return dic.object(forKey:stateCode) as? String ?? stateCode
}

Answer 3

因为，我只使用 Apple 的 GeoCoder。它只给了我美国各州的短代码。例如加利福尼亚州的 CA。

我用过google，但解析起来相当困难。 解决方案来自维基百科。https://en.wikipedia.org/wiki/List_of_states_and_territories_of_the_United_States

我已准备以下来源以使用短代码中的全名。

NSArray *arrayShortCodes=[[NSArray alloc] initWithObjects:@"AL",@"AK",@"AZ",@"AR",@"CA",@"CO",@"CT",@"DE",@"DC",@"FL",@"GA",@"HI",@"ID",@"IL",@"IN",@"IA",@"KS",@"KY",@"LA",@"ME",@"MD",@"MA",@"MI",@"MN",@"MS",@"MO",@"MT",@"NE",@"NV",@"NH",@"NJ",@"NM",@"NY",@"NC",@"ND",@"OH",@"OK",@"OR",@"PA",@"RI",@"SC",@"SD",@"TN",@"TX",@"UT",@"VT",@"VA",@"WA",@"WV",@"WI",@"WY",nil];
    NSArray *arrayFullNames=[[NSArray alloc] initWithObjects:@"Alabama",@"Alaska",@"Arizona",@"Arkansas",@"California",@"Colorado",@"Connecticut",@"Delaware",@"District of Columbia",@"Florida",@"Georgia",@"Hawaii",@"Idaho",@"Illinois",@"Indiana",@"Iowa",@"Kansas",@"Kentucky",@"Louisiana",@"Maine",@"Maryland",@"Massachusetts",@"Michigan",@"Minnesota",@"Mississippi",@"Missouri",@"Montana",@"Nebraska",@"Nevada",@"New Hampshire",@"New Jersey",@"New Mexico",@"New York",@"North Carolina",@"North Dakota",@"Ohio",@"Oklahoma",@"Oregon",@"Pennsylvania",@"Rhode Island",@"South Carolina",@"South Dakota",@"Tennessee",@"Texas",@"Utah",@"Vermont",@"Virginia",@"Washington",@"West Virginia",@"Wisconsin",@"Wyoming", nil];

     dictionaryStateNames =[[NSDictionary alloc] initWithObjects:arrayFullNames forKeys:arrayShortCodes];

现在，我们可以使用 NSDictionary 的 valueForKey 方法轻松地从短代码中获取全名。
