添加自定义UIButton到子视图
我有子视图,它通过触摸主视图中的UIbutton触发。 一旦子视图弹出,它就会显示带有我提供的信息的标签。这一切都有效。我只需要一个UIbutton来显示,这样我就可以设置它来关闭子视图并返回到主视图。我搜遍了,并没有发现任何有用的东西。添加自定义UIButton到子视图
这里是我在我的.m文件的代码如下所示:
////Button that Displays Subview with Its Label and Button
- (IBAction)showInfo:(id)sender
/////UI Subview
{UIView *mySubview = [[UIView alloc] initWithFrame:CGRectMake(0, 0,320, 480)];
[self.view addSubview:mySubview];
mySubview.backgroundColor = [UIColor blackColor];
mySubview.alpha = .7f;
//////Label in SubView
{UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(10, 10, 300, 50)];
label.text = @"Here is info";
label.textColor = [UIColor whiteColor];
label.backgroundColor= [UIColor clearColor];
[self.view addSubview:label];
////Button in Subview
//create the button
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
[button setImage:[UIImage imageNamed:@"button-info-x.png"] forState:UIControlStateNormal];
//set the position of the button
button.frame = CGRectMake(120, 252, 68, 68);
//add the button to the view
[self.view addSubview:button];
现在我只需要一个操作添加到UIButton的驳回子视图?
首先将子视图的IBOutlet添加到主视图中。
IBOutlet UIView *subView;
然后,添加的UIButton像这样子视图:
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
//set the position of the button
button.frame = CGRectMake(0, 0, 100, 30);
//set the button's title
[button setTitle:@"Click Me!" forState:UIControlStateNormal];
[btnMenu addTarget:self action:@selector(your MethodName:) forControlEvents:UIControlEventTouchUpInside];
//add the button to the view
[subView addSubview:button];
然后,
-(IBAction)your MethodName:(id)sender {
}
在上述方法中,从主视图中删除子视图。
如果您只是想为UIButton而不是标题设置图片,那么您正在寻找- (void)setImage:(UIImage *)image forState:(UIControlState)state
方法。
您应该检查UIButton reference了解更多信息。
感谢我创建了UIButton的,并有图像了。现在我只需要UIbutton就可以关闭子视图。有什么帮助吗? – Gabriel 2012-03-20 05:50:49
//创建按钮 UIButton * button = [UIButton buttonWithType:UIButtonTypeCustom]; [button setImage:[UIImage imageNamed:@“button-info-x.png”] forState:UIControlStateNormal]; //设置按钮的位置 button.frame = CGRectMake(120,252,68,68); //将按钮添加到视图 [self.view addSubview:button]; – Gabriel 2012-03-20 05:51:41
使用 - (void)addTarget:(id)目标动作:(SEL)动作forControlEvents:(UIControlEvents)controlEvents指定您需要单击按钮时触发哪个方法。现在,在这种方法中,我想你可以关闭子视图。 – Madhu 2012-03-20 05:55:48
添加目标的自定义按钮
{
.....
[button addTarget:self action:@selector(your dismiss:) forControlEvents:UIControlEventTouchUpInside];
.......
}
-(IBAction)your dismiss:(id)sender
{
// write the dismissal code here
}
我编辑了我的代码,并将其放在我的文章中。请看看,然后告诉我如何为按钮做出动作。我有点迷路 – Gabriel 2012-03-20 06:47:34
