我有这样的:的NSMutableArray NSDictionary的从
NSMutableArray *tableData;
NSMutableArray *thumbnails;
NSMutableArray *prepTime;
NSString *path = [[NSBundle mainBundle] pathForResource:@"recipes" ofType:@"plist"];
NSDictionary *dict = [[NSDictionary alloc] initWithContentsOfFile:path];
tableData = (NSMutableArray *)[dict objectForKey:@"RecipeName"];
thumbnails = (NSMutableArray *)[dict objectForKey:@"Thumbnail"];
prepTime = (NSMutableArray *)[dict objectForKey:@"PrepTime"];
,我想这样做:
- (void)tableView:(UITableView *)tableView commitEditingStyle:
(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath
{
[tableData removeObjectAtIndex:indexPath.row];
[thumbnails removeObjectAtIndex:indexPath.row];
[tableData removeObjectAtIndex:indexPath.row];
[tableView reloadData];
}
但它失败:

如何正确地将字典变成mutableArray?
试试这个 tableData =(NSMutableArray *)[[dict objectForKey:@“RecipeName”] mutableCopy] –
每个'objectForKey'返回什么? – Popeye
