objective-c - 从 NSString 解析 NSDate 时出错

Question

当我点击一行时，我的应用程序卡住，这是 didSelectRowAtIndexPath 的代码，stringDate等于这样的字符串:Feb 4 .

EditView *editController = [[EditView alloc] initWithNibName:nil bundle:nil];
[self.navigationController pushViewController:editController animated:YES];

NSDictionary *cellValue = [self.array objectAtIndex:[indexPath row]];
editController.savedString = [cellValue objectForKey:@"label"];

NSDateFormatter *df = [[NSDateFormatter alloc] init];
NSString *stringDate = [cellValue valueForKey:@"date"];

NSDate *parsedDate = [df dateFromString:stringDate];
editController.savedDate = parsedDate;

[editController release];

[self.tableView deselectRowAtIndexPath:indexPath animated:YES];

点击 NSString *stringDate = [cellValue valueForKey:@"date"]; 行上的行时出现此错误出现此错误:

* Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Invalid parameter not satisfying: date'

更新:解析的日期设置为 UIDatePicker使用日期和时间模式，我只是将字符串日期转换为 NSDate与 [timePicker setDate:savedDate animated:YES]; 一起使用

我创建了cellValue作为NSDictionary它基本上访问 plist我在哪里创建了 NSDictionary然后用格式化的 NSString 写入它。和array显示plist数组，所以我可以使用 [cellValue objectForKey:@"date"] 访问它

NSDictionary *cellValue = [self.array objectAtIndex:[indexPath row]];

您需要告诉格式化程序您的字符串满足的格式

应该是这样的:

NSDateFormatter *df = [[NSDateFormatter alloc] init];
[df setDateFormat:@"MMM d"];
