iOS Date formatting

问题:

I need to have the following date formatted while using the application with an US locale: January 1st, July 2nd, November 28th

How should I do that?

Searched with NSDateFormatter, but I'm not able to set an appropriate format and default formats are too long.

回答1:

NSDateFormatter *format = [[NSDateFormatter alloc] init];
[format setDateFormat:@"MMMM dd'st'"];

NSDate *now = [[NSDate alloc] init];

NSString *dateString = [format stringFromDate:now];
NSLog(@"%@",dateString);

this will give you the required format but you need to add some condition to add proper 'st','nd','rd' etc. like this

might this be helpful to you

NSDateFormatter *format = [[NSDateFormatter alloc] init];
[format setDateFormat:@"MMMM dd"];

NSDate *now = [[NSDate alloc] init];

NSString *dateString = [format stringFromDate:[now dateByAddingTimeInterval:(-60*60*24*10)]];
NSMutableString *tempDate = [[NSMutableString alloc]initWithString:dateString];
int day = [[tempDate substringFromIndex:[tempDate length]-2] intValue];
switch (day) {
    case 1:
    **case 21:
    case 31:**
        [tempDate appendString:@"st"];
        break;
    case 2:
    **case 22:**
        [tempDate appendString:@"nd"];
        break;
    case 3:
    **case 23:**
        [tempDate appendString:@"rd"];
        break;
    default:
        [tempDate appendString:@"th"];
        break;
}
NSLog(@"%@",tempDate);
