Question

我将iCarousel集成到我的应用程序中。它工作正常。但我的要求是在单个视图中显示两个按钮，并为这两个按钮显示特定操作。我将按钮显示为

- (UIView *) carousel:(iCarousel *)carousel viewForItemAtIndex:(NSUInteger)index reusingView:(UIView *)view{

 UIView *sampleView=[[UIView alloc]initWithFrame:CGRectMake(0, 0, 250, 300)];
    sampleView.backgroundColor=[UIColor whiteColor];

UIButton*  btntrans=[UIButton buttonWithType:UIButtonTypeCustom];
    [btntrans setFrame:CGRectMake(45, 40, 105, 50)];

    [btntrans setBackgroundColor:[UIColor clearColor]];
    btntrans.titleLabel.font = [UIFont fontWithName:@"Arial-BoldMT" size:15];
    [btntrans setTitle:@"" forState:UIControlStateNormal];
    [btntrans setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];
    [sampleView addSubview:btntrans]; 
UIButton*  btntrans1=[UIButton buttonWithType:UIButtonTypeCustom];
    [btntrans1 setFrame:CGRectMake(45, 90, 105, 50)];

    [btntrans1 setBackgroundColor:[UIColor clearColor]];
    btntrans1.titleLabel.font = [UIFont fontWithName:@"Arial-BoldMT" size:15];
    [btntrans1 setTitle:@"" forState:UIControlStateNormal];
    [btntrans1 setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];
    [sampleView addSubview:btntrans1]; 
return sampleView;
}

我们可以使用

-(void)carousel:(iCarousel *)carousel didSelectItemAtIndex:(NSInteger)index
{
    NSLog(@"ITEM SELECTED");
}

用于整个视图选择。但如何为这两个按钮设置两个特定的操作？

提前致谢。

Answer 1

在创建项目视图时将按钮操作绑定到视图控制器，然后在操作方法中使用indexForViewOrSubview：carousel方法来确定按下了哪个按钮。

如果您使用nib创建视图，请查看iCarousel示例项目中包含的控件示例，了解如何执行此操作。

你为什么不试试这个：

[btntrans addTarget:self
             action:@selector(first_action)
   forControlEvents:UIControlEventTouchUpInside];

类似地，

[btntrans1 addTarget:self
              action:@selector(second_action)
    forControlEvents:UIControlEventTouchUpInside];

相应的事件：

- (void)first_action:(id)sender{

    //This will get you the index of the selected view

    NSInteger index = [self.carousel indexOfItemViewOrSubview:sender];
                 .......
    //Do whatever you feel like

}
