从 NSString 解析 NSDate 时出错
当我点击一行时，我的应用程序冻结，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];
在 NSString *stringDate = [cellValue valueForKey:@"date"]; 行点击行时出现此错误，并出现以下错误：
* 由于未捕获的异常“NSInternalInconsistencyException”而终止应用程序，原因：“无效参数不满足：日期”
更新： 解析的日期设置为 UIDatePicker 带有日期和;时间模式，我只是将字符串日期转换为 NSDate 以便与 [timePicker setDate:savedDateanimated:YES];
我创建了 cellValue code> 作为一个 NSDictionary ，它基本上访问一个 plist ，我在其中创建了一个 NSDictionary ，然后用格式化的 NSString 编写它>。 array 显示 plist 数组，因此我可以使用 [cellValue objectForKey:@"date"] 访问它
NSDictionary *cellValue = [self.array objectAtIndex:[indexPath row]];
My app freezes when I tap a row, here is the code for didSelectRowAtIndexPath, the stringDate is equal to a string like this: 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];
I get this error when tapping the row, on the line NSString *stringDate = [cellValue valueForKey:@"date"]; with this error:
* Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Invalid parameter not satisfying: date'
UPDATE: The parsed date is set to a UIDatePicker with date & time mode, and I am simply converting the string date to a NSDate to be used with [timePicker setDate:savedDate animated:YES];
I created cellValue as a NSDictionary which basically accesses a plist where I created a NSDictionary and then wrote it with a formatted NSString. And array displays the plist array, so I can access it using [cellValue objectForKey:@"date"]
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
它应该是这样的：
You need to teach the formatter the format your string fulfills
It should be something like:
