Question

好的，我有7个NSMutableArrays，它们连接到tableview 第一个表视图告诉第二个表 - 视图加载哪一个，它加载很好，但每个我想能够添加一个项目/单元格，但是我只能为我的一个观点加载它。这是我的NSMutableArrays项目和属性列表。

属性：

@property (nonatomic) NSMutableArray *Movies;

@property (nonatomic) NSMutableArray *Tv_Shows;

@property (nonatomic) NSMutableArray *Resturuants;

@property (nonatomic) NSMutableArray *Video_Games;

@property (nonatomic) NSMutableArray *Concert_Venues;

@property (nonatomic) NSMutableArray *Foods;

@property (nonatomic) NSMutableArray *Recipes

NSMutableArray项目

 _Movies = [[NSMutableArray alloc]initWithObjects:@"Avatar", @"Kung Fu Panda", @"The Matrix", nil];
_Tv_Shows = [[NSMutableArray alloc]initWithObjects:@"Reguluar Show", @"Kung Fu Panda", @"Avatar The last Airbender", nil];
_Resturuants = [[NSMutableArray alloc]initWithObjects:@"Outback Steakhouse", @"Golden Corral", @"Wendy's", nil];
_Video_Games = [[NSMutableArray alloc]initWithObjects:@"black Ops", @"Call Of Duty", @"Modern Warfare", nil];
_Foods = [[NSMutableArray alloc]initWithObjects:@"Baked Bread", @"Pasta", @"Italian Meatballs", nil];
_Recipes = [[NSMutableArray alloc]initWithObjects:@"Chocolate Cookies", @"Brownies", @"Peanutbutter Fudge", nil];
_Concert_Venues = [[NSMutableArray alloc]initWithObjects:@"Pheonix", @"Buckeye", @"Maricopa", nil];

展开到列表方法只会加载第一个项目。

- (IBAction)unwindToTableViewController:(UIStoryboardSegue *)sender {

    AddViewController *addViewController = (AddViewController *)sender.sourceViewController;
    NSString *text = addViewController.textField.text;

    //if NOT blank and NOT whitespace
    if (![text length] == 0 && ![[text stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet]] length] == 0) {

        //Add it to the top of the data source.
        [_Movies insertObject:text atIndex:0];
        NSIndexPath *indexPath = [NSIndexPath indexPathForRow:0 inSection:0];

        //Insert it into the tableview
        [self.tableView beginUpdates];
        [self.tableView insertRowsAtIndexPaths:@[indexPath] withRowAnimation:UITableViewRowAnimationAutomatic];
        [self.tableView endUpdates];

    }
}

Answer 1

//Add it to the top of the data source.

        [_Movies insertObject:text atIndex:0];
        NSIndexPath *indexPath = [NSIndexPath indexPathForRow:0 inSection:0];

正如你所看到的，只有_movies被加载，你必须对_TvShows，Restaurants等做同样的事情......增加值（如不是0）。例如

[_Restaruants insertObject:text atIndex:1];
        NSIndexPath *indexPath = [NSIndexPath indexPathForRow:1 inSection:1];

//you may have to keep inSection:0, try it with 1 anyway

Answer 2

我明白了！

- (IBAction)unwindToTableViewController:(UIStoryboardSegue *)sender {

AddViewController *addViewController = (AddViewController *)sender.sourceViewController;
NSString *text = addViewController.textField.text;

//if NOT blank and NOT whitespace
if (![text length] == 0 && ![[text stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet]] length] == 0) {

    //Add it to the top of the data source.
    [_Movies insertObject:text atIndex:0];
    NSIndexPath *indexPath = [NSIndexPath indexPathForRow:0 inSection:0];

    //Insert it into the tableview
    [self.tableView beginUpdates];
    [self.tableView insertRowsAtIndexPaths:@[indexPath] withRowAnimation:UITableViewRowAnimationAutomatic];
    [self.tableView endUpdates];

}

} 在_Movies下添加项目像这样

[_Movies insertObject:text atIndex:0];

然后添加新的

UnwindToList包含多个NSMutableArrays
