iphone:Popover

创建Popover的几种方法：

1、通过Segue：设置Segue的Style是Popover

  

-(void) prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
    if([segue isKindOfClass:[UIStoryboardPopoverSegue class]])
    {
        self.pop = ((UIStoryboardPopoverSegue *)segue).popoverController;
        self.pop.popoverContentSize = CGSizeMake(320, 480);
    }
}

self.pop.popoverContentSize = CGSizeMake(320, 480); //设置Popover的大小

2、代码创建：

@property (strong, nonatomic) UIPopoverController *pop;

 

self.pop = [[UIPopoverControlleralloc]initWithContentViewController:vc];

self.pop.popoverContentSize = CGSizeMake(320, 480);

[self.pop presentPopoverFromRect:myButton.frame inView:self.viewpermittedArrowDirections:UIPopoverArrowDirectionDownanimated:YES];

或者

[self.pop presentPopoverFromBarButtonItem:self.myButtonBarItempermittedArrowDirections:UIPopoverArrowDirectionDownanimated:YES];
