如何在uitableview中获取这种类型的时区列表？
How to get this type of timezone list in uitableview?
我正在处理一个应用程序，我必须在 tableview 中显示这种类型的 timezone 列表。
我已经试过了:-
NSMutableArray *timeZoneArray = [[NSMutableArray alloc] initWithArray:[NSTimeZone knownTimeZoneNames]];
NSMutableArray *abbreviationArray = [[NSMutableArray alloc] init];
for (int count = 0; count < [timeZoneArray count] - 1; count = count + 1) {
NSString *timeZoneStr = [timeZoneArray objectAtIndex:count];
[abbreviationArray addObject: [timeZoneStr stringByAppendingFormat:@"(%@)",[[NSTimeZone timeZoneWithName: timeZoneStr] abbreviation]]];
}
NSLog(@"Abbreviation : %@",abbreviationArray);
我得到了这种类型的列表
但我想要这种类型的列表
请帮帮我
NSMutableArray *timeZoneArray = [[NSMutableArray alloc] initWithArray:[NSTimeZone knownTimeZoneNames]];
NSMutableArray *abbreviationArray = [[NSMutableArray alloc] init];
for (int count = 0; count < [timeZoneArray count] - 1; count = count + 1) {
NSString *timeZoneStr = [timeZoneArray objectAtIndex:count];
[abbreviationArray addObject: [timeZoneStr stringByAppendingFormat:@"(%@)",[[NSTimeZone timeZoneWithName: timeZoneStr] abbreviation]]];
}
NSLog(@"Abbreviation : %@",abbreviationArray);

iOS 框架中没有任何方法可以直接为您提供此类列表。
这两个选项可能是：
你必须维护一个plist。 （但它会随着白天的变化而失败）。
您的 API 提供商向您提供此列表。
或者你直接用这个作为 API geoname.

另一种方式google earth tools
Google API documentation
NSTimeZoneclass会提供很多你需要的，这就是Apple documentation，或者阅读Xcode.
class 方法 + knownTimeZoneNames 将提供系统的已知时区名称列表 - 您会在该列表中看到类似 "America/New_York" 的名称。
使用这些名称，您可以为每个名称创建一个 NSTimeZone 实例。
这些实例有一个 属性 secondsFromGMT，它将为您提供格式化 GMT 偏移量所需的数据。
有一种方法 localizedName:locale: 可以为您提供比 "America/New_York" 更漂亮的多种样式的时区名称。如果 none 这些样式适合您，那么您必须为名称编写自己的漂亮打印机。
以上将为您提供一个 NSTimeZone 实例数组，您可以使用 NSComparator 块对其进行排序（请参阅 NSArray documentation）。您有双键排序，主键是 GMT 偏移量，次键是名称（使用本地化比较）。
将以上内容放在一起，您就有了区域列表。

试试这个，它返回的结果类似于
"(GMT+00:00)Africa/Abidjan"
NSMutableArray *arrResult = [NSMutableArray new];
NSDateFormatter *dateFormatter = [NSDateFormatter new];
NSDate *myDate = [NSDate date];
[dateFormatter setDateStyle:NSDateFormatterLongStyle];
[dateFormatter setTimeStyle:NSDateFormatterLongStyle];
[dateFormatter setDateFormat:@"ZZZ"];
[[NSTimeZone knownTimeZoneNames] enumerateObjectsUsingBlock:^(NSString * _Nonnull obj, NSUInteger idx, BOOL * _Nonnull stop) {
NSTimeZone *timeZone = [NSTimeZone timeZoneWithName:obj];
[dateFormatter setTimeZone:timeZone];
NSString *dateString = [dateFormatter stringFromDate: myDate];
NSMutableString *mu = [NSMutableString stringWithString:dateString];
[mu insertString:@":" atIndex:3];
NSString *strResult = [NSString stringWithFormat:@"(GMT%@)%@",mu,obj];
[arrResult addObject:strResult];
}];
NSLog(@"%@", arrResult);
试试这个代码：
NSMutableArray *arrResult = [NSMutableArray new];
NSDateFormatter *dateFormatter = [NSDateFormatter new];
NSDate *myDate = [NSDate date];
[dateFormatter setDateStyle:NSDateFormatterLongStyle];
[dateFormatter setTimeStyle:NSDateFormatterLongStyle];
[dateFormatter setDateFormat:@"ZZZ"];
[[NSTimeZone knownTimeZoneNames] enumerateObjectsUsingBlock:^(NSString * _Nonnull obj, NSUInteger idx, BOOL * _Nonnull stop) {
NSTimeZone *timeZone = [NSTimeZone timeZoneWithName:obj];
[dateFormatter setTimeZone:timeZone];
NSString *dateString = [dateFormatter stringFromDate: myDate];
NSMutableString *mu = [NSMutableString stringWithString:dateString];
[mu insertString:@":" atIndex:3];
NSString *strResult = [NSString stringWithFormat:@"(GMT%@)%@",mu,obj];
[arrResult addObject:strResult];
}];
NSSortDescriptor* sortOrder = [NSSortDescriptor sortDescriptorWithKey: @"self" ascending: NO];
NSMutableArray *arr = [[NSMutableArray alloc] initWithArray:[arrResult sortedArrayUsingDescriptors: [NSArray arrayWithObject: sortOrder]]];
NSMutableArray *sortArr = [[NSMutableArray alloc] init];
for (int i = 0 ; i < arr.count; i++) {
NSString *str = [arr objectAtIndex:i];
NSRange range = [str rangeOfString:@"+"];
if (range.location == NSNotFound)
{
[sortArr addObject:str];
}
}
for (int i = arr.count -1 ; i >= 0; i--) {
NSString *str = [arr objectAtIndex:i];
NSRange range = [str rangeOfString:@"+"];
if (range.location != NSNotFound)
{
[sortArr addObject:str];
}
}
NSLog(@"%@",sortArr);

首先获取所有可用时区列表，并从 GMT 获取它们各自的时间间隔。将它们添加到字典中并对字典进行排序并打印它们：

我正在处理一个应用程序，我必须在 tableview 中显示这种类型的 timezone 列表。
我已经试过了:-
NSMutableArray *timeZoneArray = [[NSMutableArray alloc] initWithArray:[NSTimeZone knownTimeZoneNames]];
NSMutableArray *abbreviationArray = [[NSMutableArray alloc] init];
for (int count = 0; count < [timeZoneArray count] - 1; count = count + 1) {
NSString *timeZoneStr = [timeZoneArray objectAtIndex:count];
[abbreviationArray addObject: [timeZoneStr stringByAppendingFormat:@"(%@)",[[NSTimeZone timeZoneWithName: timeZoneStr] abbreviation]]];
}
NSLog(@"Abbreviation : %@",abbreviationArray);
我得到了这种类型的列表
但我想要这种类型的列表
请帮帮我
NSMutableArray *timeZoneArray = [[NSMutableArray alloc] initWithArray:[NSTimeZone knownTimeZoneNames]];
NSMutableArray *abbreviationArray = [[NSMutableArray alloc] init];
for (int count = 0; count < [timeZoneArray count] - 1; count = count + 1) {
NSString *timeZoneStr = [timeZoneArray objectAtIndex:count];
[abbreviationArray addObject: [timeZoneStr stringByAppendingFormat:@"(%@)",[[NSTimeZone timeZoneWithName: timeZoneStr] abbreviation]]];
}
NSLog(@"Abbreviation : %@",abbreviationArray);

iOS 框架中没有任何方法可以直接为您提供此类列表。
这两个选项可能是： 你必须维护一个plist。 （但它会随着白天的变化而失败）。
您的 API 提供商向您提供此列表。
或者你直接用这个作为 API geoname.
更多info
另一种方式google earth tools
Google API documentation
NSTimeZoneclass会提供很多你需要的，这就是Apple documentation，或者阅读Xcode.
class 方法 + knownTimeZoneNames 将提供系统的已知时区名称列表 - 您会在该列表中看到类似 "America/New_York" 的名称。
使用这些名称，您可以为每个名称创建一个 NSTimeZone 实例。
这些实例有一个 属性 secondsFromGMT，它将为您提供格式化 GMT 偏移量所需的数据。
有一种方法 localizedName:locale: 可以为您提供比 "America/New_York" 更漂亮的多种样式的时区名称。如果 none 这些样式适合您，那么您必须为名称编写自己的漂亮打印机。
以上将为您提供一个 NSTimeZone 实例数组，您可以使用 NSComparator 块对其进行排序（请参阅 NSArray documentation）。您有双键排序，主键是 GMT 偏移量，次键是名称（使用本地化比较）。
将以上内容放在一起，您就有了区域列表。

首先获取所有可用时区列表，并从 GMT 获取它们各自的时间间隔。将它们添加到字典中并对字典进行排序并打印它们：
-(void) printTimeZones

if(timeZK)
{
NSInteger secFromGmt = [timeZK secondsFromGMT];

// getting gmt time and values in a timeZoneValuesDict
[timeZoneValuesDict setObject:number forKey:key];
}
}
NSLog(@"\n--------Available Time Zones----------");
// sorting the timeZoneValuesDict
