的cocos2d每個CCMenuItem

Question

林像這樣建立一個CCMenu，與菜單項：

CCLabelTTF *label1 = [CCLabelTTF labelWithString:@"level 1" fontName:@"Marker Felt" fontSize:32]; 
    CCLabelTTF *label2 = [CCLabelTTF labelWithString:@"level 2" fontName:@"Marker Felt" fontSize:32]; 
    CCLabelTTF *label3 = [CCLabelTTF labelWithString:@"level 3" fontName:@"Marker Felt" fontSize:32]; 
    CCLabelTTF *label4 = [CCLabelTTF labelWithString:@"level 4" fontName:@"Marker Felt" fontSize:32]; 

    CCMenuItem *level1 = [CCMenuItemLabel itemWithLabel:label1 target:self selector:@selector(levelSelect:)]; 
    level1.tag = 1; 
    CCMenuItem *level2 = [CCMenuItemLabel itemWithLabel:label2 target:self selector:@selector(levelSelect:)]; 
    level2.tag = 2; 
    CCMenuItem *level3 = [CCMenuItemLabel itemWithLabel:label3 target:self selector:@selector(levelSelect:)]; 
    level3.tag = 3; 
    CCMenuItem *level4 = [CCMenuItemLabel itemWithLabel:label4 target:self selector:@selector(levelSelect:)]; 
    level4.tag = 4; 
    CCMenu *menu = [CCMenu menuWithItems:level1, level2, level3, level4, nil]; 
    [menu alignItemsVerticallyWithPadding:20]; 

有沒有一種方法可以讓我sewt一個for循環，要經過各CCMenuItem？我想基本上想要將其設置爲否，如果它的標籤比其他東西更少。例如：

for (ALL MENU ITEMS) { 
    if (THAT MENU ITEM.tag < 4) { 
     THAT MENU ITEM.enabled = NO; 
    } 
} 

在此先感謝

CCMenuItems添加爲您CCMenu的孩子，所以爲了通過他們迭代，你可以do.-

for (CCMenuItem *item in [menu children]) { 
    if (item.tag < 4) { 
     item.enabled = NO; 
    } 
}
