如何通过单击按钮来控制选项卡栏项目？

Question

我面临一些严重的问题。所以我正在非常具体地解释。

1. 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。

2. 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]。

这是代码我

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];

现在该怎么做我的问题是当我单击控制器 B 的按钮时然后选项卡栏选定的索引将更改，并且该视图控制器将显示在屏幕中。这意味着当我单击屏幕顶部滚动按钮中的 order 按钮时，它将显示订单控制器和选项卡栏项目索引将会改变并且与标签栏控制器 [A 控制器]

注意： A 和 B 控制器将包含相同的视图按钮和相同的控制器。我不知道该怎么做？我想要一个详细的答案。

另请参见：

如果不可能，请告诉我如何添加按钮的滚动菜单栏添加选项卡栏控制器的每个控制器，并且滚动按钮将像选项卡栏控制器项目一样重定向相同的控制器？ 现在，我希望我能得到我的解决方案。

哈哈哈.....当我解决它时真是太有趣了。无论我以不同的方式解决这个问题，我都没有使用滚动视图按钮控制器作为控制器，在每个控制器中我都对按钮中的按钮进行了功能滚动视图创建和按钮操作我刚刚更改了选项卡栏控制器的选定索引。

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];

}
