12-hour format for Xcode-settings in a "Timepicker" nsdate

I am using the NSDate object and made up my iphone with a 24-hour format, so when I'm testing my app, everything works, but a friend of mine tries the app on his iphone Codego.net, but the 12-hour format, after study, I found the issue was dated, and I don't know why this set date selector and a selector, so I read the values from the database (yes, I've checked the values, they're correct, it's not a value issue), So all the data is formatted and put together as a nsdate, and then I set the date selector and selector with the date I just created

NSDateFormatter *currentDate = [[[NSDateFormatter alloc] init] autorelease];[currentDate setDateFormat:@"yyyy-MM-dd HH:mm"];NSDate * startDate =[currentDate dateFromString:[NSString stringWithFormat:@"%d-%d-%d %d:%d",yearVal,monthVal,dayVal,hourVal,minVal]];[datePicker setDate:startDate];[timePicker setDate:startDate];

So, yearval,monthval,dayval,hourval,minval are all nsintegers ... The problem is that it works perfectly if your iphone/ipod's 24-hour clock is set, but if you have 12-hour format, it crashes and shows that

So please, if you have any ideas on how to solve this problem, I appreciate your help oh, I have read, HH returns time in 24-hour format, OK, I have all the hh, so I don't understand why I've been watching "I" or "PM" in Nslogs i's print debugging first thank you oh, sorry, I almost forgot, if I could.

[datePicker setDate:startDate];[timePicker setDate:startDate];

The app does not crash, but of course, it does not show and the date I need to note: I need 24 hours format, if I decide to choose the morning with the PM format, I will have to change all my apps and make up, I don't have enough

1. Take a look at this like: think the second answer may be the best for you. Then, depending on whether the clock is 12-hour or 24-hour, you can set [the currentdate Setdateformat: ...] accordingly. If you want a 12-hour clock, then set the currentdate as follows:

[currentDate setDateFormat:@"yyyy-MM-dd h:mm:ss a"];

If you want to have a 24-hour system, then set the currentdate as follows:

[currentDate setDateFormat:@"yyyy-MM-dd HH:mm"];
