Objective c 获取错误：从NSUserDefaults对象检索数据时，将无法识别的选择器发送到实例0x7fe2b1e71b90

获取错误：从NSUserDefaults对象检索数据时，将无法识别的选择器发送到实例0x7fe2b1e71b90

Mycode是：

NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
NSMutableArray *archiveArray = [[NSMutableArray alloc] init];
[_StarredImageUrl addObject:[_photoURLsLargeImage  objectAtIndex:gesture.view.tag]];

NSData *personEncodedObject = [NSKeyedArchiver archivedDataWithRootObject:_StarredImageUrl];
[archiveArray addObject:personEncodedObject];
[defaults setObject:archiveArray forKey:@"items"];
[defaults synchronize];
NSLog(@"Starred URL : %@",_StarredImageUrl);

NSLog(@"Starred URL : %@",personEncodedObject);
NSUserDefaults *defaults1 = [NSUserDefaults standardUserDefaults];
NSData *encodedObject = [defaults1 objectForKey:@"items"];
NSLog(@"%@",encodedObject);
_SavedArray = [NSKeyedUnarchiver unarchiveObjectWithData:encodedObject];

我正在尝试将photoUrl的数组保存在NSUserDefaults中，并从相同的NSUserDefaults加载数据，以验证是否正确保存了数据

但我在最后一行代码中遇到错误，在各种门户网站上搜索过，无法解决，请有人帮忙

完全错误：

你遗漏了错误的重要部分。显示问题中的完整错误，并指出导致错误的具体行。您好，我已经添加了完整错误，我在最后一行代码中得到了此错误：_SavedArray=[NSKeyedUnarchiver unarchiveObjectWithData:encodedObject]；您正在将

NSArray

而不是

NSData

传递给

unarchiveObjectWithData:

方法。
