nslocale

问题 I've already seen two similar questions to mine, but the answers for those questions do not work for me. I have an old project with a list of countries manually typed out inside a set of square brackets. I can easily use this in my pickerView but I'm wondering if there is a more efficient way to do this? I will be using the list of countries in a UIPickerView. 回答1: You can get a list of countries using the NSLocale class's isoCountryCodes which returns an array of [String] . From there, you

问题 I have an ios app that I'm trying to allow the users to select which currency they want to use. Right now I have the full list of currencies but there seem to be some duplicates there such as: Is there a way to filter out the others? The dollar isn't the only one with multiples some have date ranges listed with them. I'm sure there is some built-in method that does this, but my searching so far hasn't pointed me in the right direction. Here is what I am doing: let locale = NSLocale.current as

问题 I want to add event to native calender.I am having problem in getting date accurate time from string. I have set locale,24 hr format. but still getting the same bug. EKEvent *event = [EKEvent eventWithEventStore:self.eventStore]; NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init]; NSLocale *locale =[[[NSLocalealloc]initWithLocaleIdentifier:@"en_US_POSIX"]autorelease]; [dateFormatter setLocale:locale]; [dateFormatter setDateFormat:@"dd/MM/yyyy HH:mm"]; event.startDate=

问题 I'm having an issue with Swift and the iOS 8 Emulator in XCode 6.1. Indeed when I try to use NSLocale, almost every functions of it return nil. Here is how I use it: let cc = "fr" // Example let locale = NSLocale.currentLocale() let countryName = locale.displayNameForKey(NSLocaleCountryCode, value : cc) println(countryName) // Shows : nil It does work on device, iOS 7 and iOS 8 and on simulator iOS 7. It doesn't work on simulator iOS 8 and on Playground, it even EXC_BAD_ACCESS. I guess it's

问题 I have UIDatePicker in CountdownTimer mode and need to change the wording of hours and min to German locale. I tried both, to set locale to German (Germany) in storyboard and in code, but both failed and the app still shows default english words for hours and min . timePicker.locale = Locale(identifier: "de") When I configure locale on UIDatePicker in Date and Time mode, it correctly respects German locale and displays the date in german format. Any idea why locale does not change in

问题 i am making a currency selecting screen.for that i am displaying the list of currencies using the following code to create an array of currencies from which a tableview is populated NSArray *countryArray = [NSLocale ISOCurrencyCodes]; for(NSString *country in countryArray) { //NSLog(@"%@",[[NSLocale currentLocale] displayNameForKey:NSLocaleCurrencyCode value:country]); if([[NSLocale currentLocale] displayNameForKey:NSLocaleCurrencyCode value:country]) { [countriesArray addObject:[[NSLocale

问题 How can I find out whether an NSDate is a business day? That is to say, whether or not it is a weekend according to the user's current locale and calendar settings - so not hardcoded to just be Monday to Friday? NSCalendar has a firstWeekday property, but that just seems to be a presentational thing; it's Sunday in the US and Monday in the UK. EDIT: I'm not worried about holidays, I just want to be able to shade the weekends of a calendar in the same way as the built-in calendar app. 回答1:

问题 I have a bugreport that states a crash in the following line, where client is an instance of NSMutableDictionary [client setObject:[[NSLocale currentLocale] objectForKey:NSLocaleCountryCode] forKey:@"country"]; My guess is, that NSLocaleCountryCode returns nil in this line, which leads to adding a nil object to an NSDictionary which would lead to a crash. The question is, has anybody experienced an issue like this before? Are there any reasons NSLocaleCountryCode could be nil for the
