Question

我正在加载项目列表

NSMutableArray *listOfItems;
    Items *items = [ItemParser loadItemsForALevel:selectedLevel fromASuperLevel:selectedSuperLevel];

在我的for循环中，我添加到NSMutableArray以便将其显示到我的菜单层

for (Item *item in items.items) {

//Initialing a CCMenuItem and calling a removeMethod
CMenuItem *anItem = [[CCMenuItemSprite itemFromNormalSprite:[CCSprite spriteWithFile:item.picture]
 selectedSprite:[CCSprite spriteWithFile:item.picture]
target:self
selector:@selector(removeMethod:)] retain];

NSString *textToDisplay;
textToDisplay = item.ItemText;
[listOfItems addObject:textToDisplay];

}

-(void)removeMethod:(id)sender {
CCMenuItemSprite *pointedItem = (CCMenuItemSprite *)sender;

//Now I'm removing only from the layer
[CCCallFunc actionWithTarget:pointedItem selector:@selector(removeFromParentAndCleanup:)]

//How do I remove it from array?

}

如何从listOfItems数组中删除所选项并更新它？

Answer 1

将'textToDisplay'设为全局变量..在removeMethod中。您可以使用

将其从数组中删除

[listOfItems removeObjectAtIndex：[listOfItems indexOfObject：textToDisplay]];
