Invalid parameter not satisfying: date
nsdate, nsdateformatter, objective-c
Solution
Note that you may be getting bit by the locale "feechure". You need to set the locale of your NSDateFormatter.
Set up a phone with US locale and then set the 12/24 setting to 24. Also set a phone with European locale and then set the 12/24 setting to 12. Likely one or the other or both will fail.
Problem
I'm having an issue coming in from Crashlytics. I have debugging parameters on so I am seeing what parameters there are. ``` datePicker = [[UIDatePicker alloc] initWithFrame:CGRectMake(0, 40, 0, 0)]; NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init]; NSString *startTimeString = [MathFunctions minutesToTimeString:[appointment.start_time integerValue]]; NSLog(@"Time: %@",startTimeString); NSLog(@"Date: %@", appointment.date); [dateFormatter setDateFormat:@"yyyyMMdd h:mm a"]; [Crashlytics setObjectValue:[NSString stringWithFormat:@"%@ %@", appointment.date, startTimeString] forKey:@"ResAddDate"]; NSString *dateTimeString = [NSString stringWithFormat:@"%@ %@", appointment.date, startTimeString]; NSLog(@"Date String: %@", dateTimeString); datePicker.date = [dateFormatter dateFromString:dateTimeString]; ``` The crashlog coming from crashlytics shows that the date is formatted properly `RESADDDATE: 20120621 12:00 AM` The crash occurs on `datePicker.date = [dateFormatter dateFromString:dateTimeString];` Why is this crashing if the date format is there and correct?
