IOS 在iphone中PopoverViewController的使用

@property(nonatomic,retain)PopoverViewController *myPopover;

-(void)popover{

    _myPopover = [[PopoverViewControlleralloc]initWithNibName:@"PopoverViewController"bundle:nil];

    _myPopover.preferredContentSize =CGSizeMake(297,165);

    _myPopover.modalPresentationStyle =UIModalPresentationPopover;

    _myPopover.popoverPresentationController.sourceView =rightButton; //rect参数是以view的左上角为坐标原点（0，0）

    _myPopover.popoverPresentationController.sourceRect =rightButton.bounds;//指定箭头所指区域的矩形框范围（位置和尺寸），以view的左上角为坐标原点

//    CGRect frame = CGRectMake(50, 80, 297, 165);

//    myPopover.popoverPresentationController.sourceRect = frame;

    

    _myPopover.popoverPresentationController.permittedArrowDirections =UIPopoverArrowDirectionUp;//箭头方向

    NSMutableArray *saveArr = [[NSUserDefaultsstandardUserDefaults]objectForKey:@"saveColor"];

    if(saveArr.count){

        if([saveArr[0] floatValue] ==0.0){

            _myPopover.popoverPresentationController.backgroundColor = [UIColor colorWithRed:46.0/255.0 green:46.0/255.0 blue:46.0/255.0 alpha:1.0];

        }else{

            _myPopover.popoverPresentationController.backgroundColor = [UIColor whiteColor];

        }

    }else{

        _myPopover.popoverPresentationController.backgroundColor = [UIColor whiteColor];

    }

    _myPopover.popoverPresentationController.delegate = self;

    [self presentViewController:_myPopover animated:YES completion:nil];

}

- (UIModalPresentationStyle)adaptivePresentationStyleForPresentationController:(UIPresentationController *)controlle

{

    

    return UIModalPresentationNone;

}

在PopoverViewController.m  中完成布局及设置

    self.popoverView.frame =CGRectMake(50,80, 297, 165);
