如何解析可能采用两种不同日期格式的日期字符串，并在iOS和Android中将其显示为本地时间？

I’m getting a date string in two different time formats as the following:

我正在以两种不同的时间格式获取日期字符串,如下所示:

yyyy-MM-dd’T'HH:mm:ss.SSS'Z’ like 2015-03-05T05:57:58.854Z and yyyy-MM-dd’T’HH:mm:ss.SSSZ like 2015-03-05T11:27:58 +0530.

yyyy-MM-dd'T'HH:mm:ss.SSS'Z'如2015-03-05T05:57:58.854Z和yyyy-MM-dd'T'HH:mm:ss.SSSZ如2015-03- 05T11:27:58 +0530。

I have to parse the string and display the time in the local timezone. How do I parse a date string which may be in two different date formats and display it to local time?

You can try with parsing with a format first, if the it gives you a date object, use that, otherwise use the other format. A rough draft for iOS will be as follow:

您可以先尝试使用格式解析,如果它为您提供了日期对象,请使用该格式,否则使用其他格式。适用于iOS的草稿如下:

NSDate* dateFromString(NSString *string){
    NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
    //try with first format
    [formatter setDateFormat:@"yyyy-MM-dd'T'HH:mm:ss.SSS'Z'"];
    //convert the date
    NSDate *date = [formatter dateFromString:string];

    //check if the first format worked or not
    if (!date) {
        //try with the other format.
        [formatter setDateFormat:@"yyyy-MM-dd'T'HH:mm:ss.SSSZ"];
        //return the converted date
        return [formatter dateFromString:string];
    }
    return date;
}

You'll be calling it like this:

你会这样称呼它:

NSDate *aDate = dateFromString( @"2015-03-05T05:57:58.854Z");
NSDate *anotherDate =dateFromString( @"2015-03-05T11:27:58 +0530");

Use the same technique for android.

对android使用相同的技术。
