我有這樣的:的NSMutableArray NSDictionary的從
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"];
,我想這樣做:
- (void)tableView:(UITableView *)tableView commitEditingStyle:
(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath
{
[tableData removeObjectAtIndex:indexPath.row];
[thumbnails removeObjectAtIndex:indexPath.row];
[tableData removeObjectAtIndex:indexPath.row];
[tableView reloadData];
}
但它失敗:

如何正確地將字典變成mutableArray?
試試這個 tableData =(NSMutableArray *)[[dict objectForKey:@「RecipeName」] mutableCopy] –
每個'objectForKey'返回什麼? – Popeye
