我正在设置滚动视图,在该视图上我有两个按钮,但是,按钮没有显示在图像视图上。当我设置滚动视图。我想要一个图像上的按钮:
-(void)addScrollView{
scrollview.contentSize=CGSizeMake(1280,960);
CGRect fullScreenRect=[[UIScreen mainScreen] applicationFrame];
scrollview=[[UIScrollView alloc] initWithFrame:fullScreenRect];
scrollview.contentSize=CGSizeMake(320,758);
imageview = [[UIImageView alloc]initWithImage:
[UIImage imageNamed:@"IPHome Page Final.jpg"]];
[scrollview addSubview:imageview];
scrollview.minimumZoomScale = 0.5;
scrollview.maximumZoomScale = 3;
scrollview.contentSize = CGSizeMake(imageview.frame.size.width,
imageview
.frame.size.height);
scrollview.delegate = self;
[imageview addSubview:CameraButton];
[imageview addSubview:SoundButton];
[self.view addSubview:scrollview];
}
我该怎么做?

您的代码会处理按钮上发生的事件(例如在内部/外部触摸..etc)您必须先创建按钮。通过UIButton *button = [[UIButton alloc] initWithFrame:CGRectMake(0, 0, 44, 44)]
以编程方式创建按钮,或将其添加到“界面”构建器并为其创建IBOutlet
。
