大家好,我正在做一个应用程序,我将在菜单中实现按钮的滑动。像滑块这样包含许多按钮。
我浏览了以下链接
http://blog.sallarp.com/iphone-sliding-menu/
在上面的链接中,他们已经在Appdelegate方法中设置了所有内容...而在我的应用程序中有许多视图将继续进一步..所以任何人都可以帮助我如何实现按钮的滑动菜单栏?
谢谢你。

基本上,您所引用的滑动菜单由包含UIButtons作为子视图的UIScrollView组成。将滚动视图的contentSize设置为CGSizeMake(按钮的总宽度,一个按钮的高度)和enableScrolling为YES。
创建一个控制菜单的视图控制器可能是个好主意。此VC既可以生成滚动视图,也可以生成按钮,并作为按钮操作的目标。

·H
IBOutlet UIScrollView *scrollView;
@property ( nonatomic , retain ) IBOutlet UIScrollView *scrollView;
-(void)AppleVijayAtFacebookDotCom:(id)sender;
-(void)createMenuWithButtonSize:(CGSize)buttonSize withOffset:(CGFloat)offset noOfButtons:(int)totalNoOfButtons;
的.m
@synthesize scrollView;
-(void)AppleVijayAtFacebookDotCom:(id)sender{
NSLog(@"AppleVijayAtFacebookDotCom called");
UIButton *button=(UIButton *)sender;
if (button.tag == 0) {
NSLog(@"hey have clicked first button, this is my tag : %i \n\n",button.tag);
}
else if (button.tag == 1) {
NSLog(@"hey have clicked second button, this is my tag : %i \n\n",button.tag);
}
// ......like this
NSLog(@"button clicked is : %iBut \n\n",button.tag);
}
-(void)createMenuWithButtonSize:(CGSize)buttonSize withOffset:(CGFloat)offset noOfButtons:(int)totalNoOfButtons{
for (int i = 0; i < totalNoOfButtons; i++) {
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
[button addTarget:self action:@selector(AppleVijayAtFacebookDotCom:) forControlEvents:UIControlEventTouchUpInside];
//[button1 setImage:[UIImage imageNamed:@"Button.png"] forState:UIControlStateNormal];//with image
//OR
[button setTitle:[NSString stringWithFormat:@"%iBut",i] 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 = 10;//half of the width
button.layer.borderColor=[UIColor redColor].CGColor;
button.layer.backgroundColor=[UIColor blackColor].CGColor;
button.layer.borderWidth=2.0f;
button.tag=i;
[self.scrollView addSubview:button];
}
self.scrollView.contentSize=CGSizeMake((buttonSize.width + offset) * totalNoOfButtons, buttonSize.height);
//self.navigationItem.titleView=self.scrollView;//if u have navigationcontroller then enable this line
}
不要忘记在界面构建器中连接scrollView
在IB中创建滚动视图时确保你的scrollView高度为44.这是导航栏的默认值。所以它看起来不错。
in viewDidLoad call
[self createMenuWithButtonSize:CGSizeMake(70.0, 30.0) withOffset:20.0f noOfButtons:30];
