UIPopoverController 取消箭头

UIPopoverController *popViewController = [[UIPopoverController alloc] initWithContentViewController:exchange_ViewController];

popViewController.contentViewController.view.backgroundColor = [UIColor whiteColor];

[popViewController setPopoverContentSize:CGSizeMake(400, 430) animated:YES];

popViewController.delegate = self;

[popViewController presentPopoverFromRect:CGRectMake(312, 95, 400, 430) inView:detailImageView permittedArrowDirections:0 animated:YES];

取消箭头

permittedArrowDirections:0

代理方法

- (void)popoverControllerDidDismissPopover:(UIPopoverController *)popoverController

{

[popViewController release];

}

// we finished rotating, if a popover is allocated, show it again in the new orientation

//popoverRect的中心点是用来画箭头的，如果中心点如果出了屏幕，系统会优化到窗口边缘

[self.popoverControllerpresentPopoverFromRect:savedPopoverRect

inView:self.view//上面的矩形坐标是以这个view为参考的

permittedArrowDirections:UIPopoverArrowDirectionAny//箭头方向

animated:YES];
