UIWebView中的PDF无法正常工作

我有两个UIPopoverController。当我点击相应的按钮时,每个人都会在UIWebViewDelegate中打开一个pdf。 但是,只有一个有效。 A和B这两个按钮都具有点击功能的格式(除了按钮B会说ButtonB不是ButtonA)

- (IBAction)openPDF_Pictures_A:(id)sender
{


    ButtonAPDFViewController *DWV =[[ButtonAPDFViewController alloc] initWithNibName:nil bundle:nil];

    self.masterPopOverController = [[UIPopoverController alloc] initWithContentViewController:DWV];

    [self.masterPopOverController presentPopoverFromRect:[sender frame] inView:[sender superview] permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
    [self.masterPopOverController setPopoverContentSize:CGSizeMake(600, 800) animated:NO];




}

在每个UIWebView的UIViewController中,是:

#import "ButtonAViewController.h"

@interface ButtonAViewController ()

@end

@implementation ButtonAViewController

@synthesize buttonAPDFView;

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        // Custom initialization
    }
    return self;
}

- (void)viewDidLoad
{
    [super viewDidLoad];


    NSString *path = [[NSBundle mainBundle] pathForResource:@"partA" ofType:@"pdf"];
    NSURL *targetURL = [NSURL fileURLWithPath:path];
    NSURLRequest *request = [NSURLRequest requestWithURL:targetURL];
    [buttonAPDFView loadRequest:request];



}
- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

@end

按钮A和B都在同一视图上。我确实让其中一个IBActions使用masterPopOverController2和一个masterPopOverController来查看是否会解决任何事情,但它没有。不起作用的那个打开了一个弹出框,但它没有在弹出框中显示PDF。有什么建议吗?

刚才意识到我没有在xib中的UIView中添加UIWebView ...
