Question

我面临一些严重的问题。所以我非常具体地解释。

两个视图控制器A）UITabbar控制器B）包含按钮滚动视图的视图控制器。
我在A控制器的导航栏上有子视图B控制器[图像中的蓝色按钮] [图像下方图像的黑色按钮]。

enter image description here

这是代码我该怎么做呢

scrollButtonView = [[scrollViewButtons alloc] initWithNibName:@"scrollViewButtons" bundle:nil];
CGRect frame = CGRectMake(0, 20, 320, 43);
scrollButtonView.view.frame = frame;
scrollButtonView.view.userInteractionEnabled =YES;
[self.navigationController.view addSubview:scrollButtonView.view];

现在我的问题是当我点击控制器B的按钮然后tabbarbar选择索引将改变并且视图控制器将显示在screen.thats意味着我将点击滚动按钮中的order按钮屏幕顶部然后它将显示订单控制器和tabbar项目索引将更改，与tabbar控制器相同[A控制器]

注意： A和B控制器都将包含相同的视图按钮和相同的控制器。我不知道怎么办？我想以详细的方式回答。

还请参见：

如果不可能那么告诉我如何添加滚动菜单栏的按钮添加标签栏控制器的每个控制器和滚动按钮将重定向像tabbar控制器项目相同的控制器？现在，我希望我能得到我的解决方案。

哈哈哈......当我解决它时，它真是太有趣了。无论我以不同的方式解决了这个问题，我都没有使用scrollview按钮控制器来控制器，在每个控制器中我都将功能发挥到了哪里滚动视图中的按钮创建和按钮的操作我只需更改选项卡控制器的选定索引。

在-(void)viewDidload我写了这段代码

     UIView *scrollViewBackgroundView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 45)];
scrollViewBackgroundView.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"topmenu_bg.png"]];

menuScrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(5,0,320,40)];
menuScrollView.showsHorizontalScrollIndicator = FALSE;
menuScrollView.showsVerticalScrollIndicator = FALSE;
menuScrollView.bounces = TRUE;
[scrollViewBackgroundView addSubview:menuScrollView];
[self.view addSubview:scrollViewBackgroundView];

[self createMenuWithButtonSize:CGSizeMake(92.0, 30.0) withOffset:5.0f noOfButtons:7];

这里是按钮创建和操作

-(void)mybuttons:(id)sender{    
NSLog(@"mybuttons called");
UIButton *button=(UIButton *)sender;
NSLog(@"button clicked is : %iBut \n\n",button.tag);
int m = button.tag;
for(int j=0;j<8;j++){
    if(button.tag == m){
        self.tabBarController.selectedIndex = m;
        [button setBackgroundImage:[UIImage imageNamed:@"btn_topmenu_hover.png"] forState:UIControlStateHighlighted]; //sets the background Image]            
    }
    if(button.tag != m){
        [button setBackgroundImage:[UIImage imageNamed:@"btn_topmenu_normal.png"] forState:UIControlStateNormal]; //sets the background Image]
    }
}
}       

 -(void)createMenuWithButtonSize:(CGSize)buttonSize withOffset:(CGFloat)offset noOfButtons:(int)totalNoOfButtons{

NSLog(@"inserting into the function for menu bar button creation"); 
for (int i = 0; i < totalNoOfButtons; i++) {

    UIButton *button = [[UIButton buttonWithType:UIButtonTypeCustom] retain];
    [button addTarget:self action:@selector(mybuttons:) forControlEvents:UIControlEventTouchUpInside];
    (button).titleLabel.font =  [UIFont fontWithName:@"Arial" size:12];
    if(i==0){
        [button setTitle:[NSString stringWithFormat:@"Dashboard"] forState:UIControlStateNormal];//with title
        [button setBackgroundImage:[UIImage imageNamed:@"btn_topmenu_hover.png"] forState:UIControlStateNormal]; //sets the background Image]
    }
    if(i==1){
        [button setTitle:[NSString stringWithFormat:@"Order"] forState:UIControlStateNormal];//with title
        [button setBackgroundImage:[UIImage imageNamed:@"btn_topmenu_normal.png"] forState:UIControlStateNormal]; //sets the background Image]

    }
    if(i==2){
        [button setTitle:[NSString stringWithFormat:@"Product"] forState:UIControlStateNormal];//with title
        [button setBackgroundImage:[UIImage imageNamed:@"btn_topmenu_normal.png"] forState:UIControlStateNormal]; //sets the background Image]

    }
    if(i==3){
        [button setTitle:[NSString stringWithFormat:@"Customers"] forState:UIControlStateNormal];//with title
        [button setBackgroundImage:[UIImage imageNamed:@"btn_topmenu_normal.png"] forState:UIControlStateNormal]; //sets the background Image]

    }
    if(i==4){
        [button setTitle:[NSString stringWithFormat:@"Content"] forState:UIControlStateNormal];//with title
    }
    if(i==5){
        [button setTitle:[NSString stringWithFormat:@"Site Analysis"] forState:UIControlStateNormal];//with title
        [button setBackgroundImage:[UIImage imageNamed:@"btn_topmenu_normal.png"] forState:UIControlStateNormal]; //sets the background Image]

    }
    if(i==6){
        [button setTitle:[NSString stringWithFormat:@"Store Settings"] forState:UIControlStateNormal];//with title
        [button setBackgroundImage:[UIImage imageNamed:@"btn_topmenu_normal.png"] forState:UIControlStateNormal]; //sets the background Image]

    }
    if(i==7){
        [button setTitle:[NSString stringWithFormat:@"CMS Settings"] forState:UIControlStateNormal];//with title
        [button setBackgroundImage:[UIImage imageNamed:@"btn_topmenu_normal.png"] forState:UIControlStateNormal]; //sets the background Image]

    }
    button.frame = CGRectMake(i*(offset+buttonSize.width), 6.0, buttonSize.width, buttonSize.height);
    button.clipsToBounds = YES;
    button.showsTouchWhenHighlighted=YES;
    button.layer.cornerRadius = 5;//half of the width
    button.layer.borderColor=[UIColor clearColor].CGColor;
    button.layer.borderWidth=0.0f;
    button.tag=i;
    [menuScrollView addSubview:button];
}
menuScrollView.contentSize=CGSizeMake((buttonSize.width + offset) * totalNoOfButtons, buttonSize.height);
[self.view addSubview:menuScrollView];

}

如何通过按钮点击控制标签栏项目？
