我在从Crashlytics进来的问题。 我有，所以我看到有什么参数调试参数。
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];
从crashlytics未来的系统崩溃日志显示，日期的格式正确
RESADDDATE: 20120621 12:00 AM
上发生崩溃datePicker.date = [dateFormatter dateFromString:dateTimeString];
这是为什么崩溃如果日期格式是存在的，正确的吗？
