我正在使用 UIScrollView 进行分页,我注意到我分页的后续视图都没有调用它们的数据源/委托。我将它作为数据源/委托连接到他们的 XIB 中,并在代码中以这种方式设置它,但它仍然没有被调用。
我猜问题出在这里......我在哪里进行分页并插入第二和第三个视图。委托/数据源都不能处理被分页的第二个或第三个视图。
requestDetailTwoViewController *controller = [viewControllers objectAtIndex:1];
requestDetailThreeViewController *controller2 = [viewControllers objectAtIndex:2];
if ((NSNull *)controller == [NSNull null])
{
if(page == 1)
{
controller = [[requestDetailTwoViewController alloc] initWithRequestNumber:[request objectForKey:@"RequestID"] forID:self.employeeIDfromHome];
[viewControllers replaceObjectAtIndex:page withObject:controller];
CGRect frame = scrollView.frame;
frame.origin.x = frame.size.width * 1;
frame.origin.y = 0;
controller.view.frame = frame;
[scrollView addSubview:controller.view];
}
}
if ((NSNull *)controller2 == [NSNull null])
{
if(page == 2)
{
controller2 = [[requestDetailThreeViewController alloc] initWithRequestNumber:[request objectForKey:@"RequestID"]];
[viewControllers replaceObjectAtIndex:page withObject:controller2];
[self addChildViewController:controller2];
CGRect frame = scrollView.frame;
frame.origin.x = frame.size.width * 2;
frame.origin.y = 0;
controller2.view.frame = frame;
[scrollView addSubview:controller2.view];
[controller2 didMoveToParentViewController:self];
}
}
谢谢!
