Question

可能重复：
How can i add more than 10 buttons on a navigationbar in iphone application development?

我想在导航栏上设置一个UIScrollView，其中包含八个按钮，当我按下下一个或上一个按钮时，此导航栏还包含leftbaritem和rightbaritem，然后scrollview必须使用此按钮滚动，因为某些按钮将会出现滚动视图框架。

到目前为止，我已经制作了滚动视图和按钮，但问题是按钮现在正在显示。任何人都可以通过举例或发送源代码来帮助我。

先谢谢

修改

topToolBar = [UIToolbar new];
[topToolBar sizeToFit];
topToolBar.frame = CGRectMake(0,0, 280, 50);
topToolBar.barStyle = UIBarStyleBlackTranslucent;

segmentedControllerView = [[UIView alloc] initWithFrame:CGRectMake(5, 0, 280, 50)];
segmentedControllerView.clipsToBounds = YES;

UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[button addTarget:self 
           action:@selector(aMethod:)
 forControlEvents:UIControlEventTouchDown];
[button setTitle:@"Show View" forState:UIControlStateNormal];
button.frame = CGRectMake(0,0, 60.0, segmentedControllerView.frame.size.height -10);
button.clipsToBounds = YES;
[segmentedControllerView addSubview:button];

UIButton *button2 = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[button2 addTarget:self 
           action:@selector(aMethod2:)
 forControlEvents:UIControlEventTouchDown];
[button2 setTitle:@"Show View2" forState:UIControlStateNormal];
button2.frame = CGRectMake(60,0, 60.0, segmentedControllerView.frame.size.height - 10);
[segmentedControllerView addSubview:button2];

UIButton *button3 = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[button3 addTarget:self 
           action:@selector(aMethod3:)
 forControlEvents:UIControlEventTouchDown];
[button3 setTitle:@"Show View" forState:UIControlStateNormal];
button3.frame = CGRectMake(120,0, 60.0, segmentedControllerView.frame.size.height -10 );
[segmentedControllerView addSubview:button3];

UIButton *button4 = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[button4 addTarget:self 
           action:@selector(aMethod4:)
 forControlEvents:UIControlEventTouchDown];
[button4 setTitle:@"Show View" forState:UIControlStateNormal];
button4.frame = CGRectMake(180,0, 60.0, segmentedControllerView.frame.size.height -10 );
[segmentedControllerView addSubview:button4];

[topToolBar addSubview:segmentedControllerView];
self.navigationItem.titleView = topToolBar;

我也接近结果，但问题是当我按下下一个或上一个按钮然后它移动到下一个或上一个按钮但它应该在视图下移动....

这是动画代码：

   -(void)previousBarButtonAction{

[UIView beginAnimations: @"moveField"context: nil];
[UIView setAnimationDelegate: self];
[UIView setAnimationDuration: 0.5];
[UIView setAnimationCurve: UIViewAnimationCurveEaseInOut];
segmentedControllerView.frame = CGRectMake(segmentedControllerView.frame.origin.x - 50,
                                   segmentedControllerView.frame.origin.y,
                                   segmentedControllerView.frame.size.width,
                                   segmentedControllerView.frame.size.height);
[UIView commitAnimations];


}
-(void)nextBarButtonAction{

[UIView beginAnimations: @"moveField"context: nil];
[UIView setAnimationDelegate: self];
[UIView setAnimationDuration: 0.5];
[UIView setAnimationCurve: UIViewAnimationCurveEaseInOut];
segmentedControllerView.frame = CGRectMake(segmentedControllerView.frame.origin.x + 50,
                              segmentedControllerView.frame.origin.y,
                              segmentedControllerView.frame.size.width,
                              segmentedControllerView.frame.size.height);
[UIView commitAnimations];

}

我解决这个问题的方式略有不同......

在viewDidLoad我已经取了scrollView并调用了我的函数

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


[self createMenuWithButtonSize:CGSizeMake(70.0, 30.0) withOffset:20.0f noOfButtons:7];

然后在我的function我创建了我的菜单buttons，它看起来像navigation bar上的按钮

-(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];

    [button addTarget:self action:@selector(mybuttons:) forControlEvents:UIControlEventTouchUpInside];
    if(i==0){
    [button setTitle:[NSString stringWithFormat:@"Dashboard"] forState:UIControlStateNormal];//with title
    }
    else if(i==1){
        [button setTitle:[NSString stringWithFormat:@"Order"] forState:UIControlStateNormal];//with title
    }
    else if(i==2){
        [button setTitle:[NSString stringWithFormat:@"Product"] forState:UIControlStateNormal];//with title
    }
    else if(i==3){
        [button setTitle:[NSString stringWithFormat:@"Customers"] forState:UIControlStateNormal];//with title
    }
    else if(i==4){
        [button setTitle:[NSString stringWithFormat:@"Content"] forState:UIControlStateNormal];//with title
    }
    else if(i==5){
        [button setTitle:[NSString stringWithFormat:@"Site Analysis"] forState:UIControlStateNormal];//with title
    }
    else if(i==6){
        [button setTitle:[NSString stringWithFormat:@"Store Settings"] forState:UIControlStateNormal];//with title
    }
    else if(i==7){
        [button setTitle:[NSString stringWithFormat:@"CMS Settings"] forState:UIControlStateNormal];//with title
    }
    button.frame = CGRectMake(i*(offset+buttonSize.width), 8.0, buttonSize.width, buttonSize.height);
    button.clipsToBounds = YES;
    button.showsTouchWhenHighlighted=YES;
    button.layer.cornerRadius = 0;//half of the width
    //button.layer.borderColor=[UIColor clearColor];
    button.layer.backgroundColor=[UIColor blueColor].CGColor;
    button.titleLabel.font = [UIFont systemFontOfSize:10];
    button.layer.borderWidth=0.0f;
    button.tag=i;
    [menuScrollView addSubview:button];
}
menuScrollView.contentSize=CGSizeMake((buttonSize.width + offset) * totalNoOfButtons, buttonSize.height);
[self.view addSubview:menuScrollView];

}

它解决了...快乐编码......：））
