從自定義UITableViewCell中委託製表符

Question

我已經創建了一個包含UITabBar屬性的特定列表的自定義單元格。這個單元格有其特定的類叫做RecomandationCell，我已經聲明瞭這些屬性。

我用這個自定義單元格來創建多個小區不同的對象，我也想知道，當我在一個特定的行點擊該標籤欄的項目稱之爲來自代表團的<UITabBarControllerDelegate>這是

- (void)tabBar:(UITabBar *)tabBar didSelectItem:(UITabBarItem *)item 
{ 
    if (item.tag==0) 
    { 
     NSLog(@"Likes Clicked"); 
    } 
    if (item.tag==1) 
    { 
     NSLog(@"Comments Clicked"); 
    } 
    if (item.tag==2) 
    { 
     NSLog(@"Shares Clicked"); 
    } 
    if (item.tag==3) 
    { 
     NSLog(@"Add Clicked"); 
    } 
    if (item.tag==4) 
    { 
     NSLog(@"Ratings Clicked"); 
    } 
} 

其方法

問題是，這種方法不會被解僱，因爲我不知道在哪裏委託它，甚至如果我委託它，我不知道在特定索引點擊了哪個標籤欄。

任何建議，或者如果您需要更多的信息，請不要猶豫，評論

OKY u能做到這樣

在CustomCell.h

@interface CustomTabedCell : UITableViewCell<UITabBarDelegate>//confirms to delegate 

in CustomCell.m file

#import "CustomTabedCell.h" 

    @implementation CustomTabedCell 

    - (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier 
{ 
    self = [super initWithStyle:style reuseIdentifier:reuseIdentifier]; 
    if (self) { 
    // Initialization code 

    UITabBarItem *firstItem = [[UITabBarItem alloc]initWithTitle:@"1" image:nil tag:10];//you can specify image hear i put nil 
    UITabBarItem *secondItem = [[UITabBarItem alloc]initWithTitle:@"2" image:nil tag:11]; // ... give tag number 
    UITabBar *tabBar = [[UITabBar alloc]initWithFrame:CGRectMake(0, 0, 320, 70)]; //leave this if u are added in xib 
    tabBar.delegate = self; //delegate to custom cell itself 
    tabBar.tag = 100;//leave 
    tabBar.items = [NSArray arrayWithObjects:firstItem,secondItem, nil];//add to tab bar 
    [self.contentView addSubview:tabBar]; 

    } 
    return self; 
} 

    //in custom cell u are getting the delegate call's 

- (void)tabBar:(UITabBar *)tabBar didSelectItem:(UITabBarItem *)item 
    { 
    if (item.tag==10) //compare using tages as u added to tabed bar 
    { 
     NSLog(@"Likes Clicked"); 
    } 
    if (item.tag==11) 
    { 
     NSLog(@"Comments Clicked"); 
    } 
    if (item.tag==12) 
    { 
     NSLog(@"Shares Clicked"); 
    } 
    if (item.tag==13) 
    { 
     NSLog(@"Add Clicked"); 
    } 
    if (item.tag==14) 
    { 
     NSLog(@"Ratings Clicked"); 
    } 
} 

在此之後ü可以調用自定義的委託方法到控制器作進一步處理

Answer 2

第一：你已經在爲電池中，當你可能想指定UITabBarDelegate接口指定UITabBarControllerDelegate。

第二：創建選項卡時設置委託。您提供的代碼不會顯示此內容。你需要在某處初始化tabbar，然後在其上設置一個委託。

第三：在單元格中設置特定內容的位置將在tableviewcontroller的cellForRowAtIndexPath中。

第四：要獲得抽頭的TabBar項的指數，你可以做的是，在didSelectItem方法：

NSUInteger indexOfTab = [[tabBar items] indexOfObject:item]; 
NSLog(@"Tab index = %u", indexOfTab);
