iphone - 如何在iPhone SDK中更改日期格式

Question

我从Web服务日期收到响应，例如“2012-08-17T00:00:00”。我只想显示日期，例如17-08-2012。如何更改日期格式并删除该时间...

Answer 1

//String froms web service(ws) 

NSString *stringFromWS =[NSString stringWithString:@"2012-08-17T00:00:00"];


//date formatter for the above string
NSDateFormatter *dateFormatterWS = [[NSDateFormatter alloc] init];
[dateFormatterWS setDateFormat:@"yyyy-MM-dd'T'HH:mm:ss"];

NSDate *date =[dateFormatterWS dateFromString:stringFromWS];


//date formatter that you want 

NSDateFormatter *dateFormatterNew = [[NSDateFormatter alloc] init];
[dateFormatterNew setDateFormat:@"dd-MM-yyyy"];

NSString *stringForNewDate = [dateFormatterNew stringFromDate:date];

NSLog(@"Date %@",stringForNewDate);
