将日期字符串（2016-04-27T08：06：07.531Z）转换为特定日期格式dd.MM.YYYY

Question

I have date string in the format 2016-04-27T08:06:07.531Z and want to convert into 2016.04.27. I have tried following code

NSString *dateString = @"2016-04-27T08:06:07.531Z";

NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"yyyy-MM-ddTHH:mm:ss.Z"];

NSDate *dateReceived = [dateFormatter dateFromString:dateString];
[dateFormatter setDateFormat:@"dd.MM.YYYY"];

NSString *dateReq = [dateFormatter stringFromDate:dateReceived];

NSLog(@"Date Req:%@",dateReq);

I am getting null in console for NSLog. Any help will be appreciated. Thanks.

Answer 1

use like

NSString *dateString = @"2016-04-27T08:06:07.531Z";
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];

[dateFormatter setDateFormat:@"yyyy-MM-dd'T'HH:mm:ss.SSSZ"];

NSDate *dateReceived = [dateFormatter dateFromString:dateString];
                             // 2016.04.27
[dateFormatter setDateFormat:@"yyyy.MM.dd"];

NSString *dateReq = [dateFormatter stringFromDate:dateReceived];

NSLog(@"Date Req:%@",dateReq);

Plz just change your date formatter's date format

[dateFormatter setDateFormat:@"yyyy-MM-dd'T'HH:mm:ss.SSSZ"];

instead of

[dateFormatter setDateFormat:@"yyyy-MM-ddTHH:mm:ss.Z"];

try this it will help you --

NSString *date = @"2011-02-27T08:06:07.531Z";
NSDateFormatter *dFormat = [[NSDateFormatter alloc] init];

[dFormat setDateFormat:@"yyyy-MM-dd'T'HH:mm:ss.SSSZ"];

NSDate *dReceive = [dFormat dateFromString:dateString];

[dFormat setDateFormat:@"yyyy-MM-ddTHH:mm:ss.Z"];

NSString *dateReq = [dateFormatter stringFromDate:dReceive];

just change date format

[dFormat setDateFormat:@"yyyy-MM-ddTHH:mm:ss.Z"];

使用日期格式为： [dFormat setDateFormat:@"yyyy-MM-ddTHH:mm:ss.Z"];
