Question

我正在尝试使用故事板实现2个Web视图，这两个视图都链接到另一个在线网页。出于某种原因，我没有得到任何错误，但只有PriceViewController工作。另一个VC生成白页......

我正在使用这4个文件：

PricesViewcontroller.h

#import <UIKit/UIKit.h>

 @interface PricesViewController : UIViewController

 {
     IBOutlet UIWebView *WebView; }

 @property (nonatomic, retain) UIWebView *WebView;

 @end

PricesViewController.m

 #import "PricesViewController.h"

 @interface PricesViewController ()

 @end

 @implementation PricesViewController @synthesize WebView;

 - (void)viewDidLoad {
    [WebView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@"http://www.sparein.be/full_pricelist.pdf"]]];
      [super viewDidLoad];

 }


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

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

 @end

ReservationsViewController.h

#import <UIKit/UIKit.h>

 @interface ReservationsViewController : UIViewController

 {
     IBOutlet UIWebView *WebView2; }

 @property (nonatomic, retain) UIWebView *WebView2;

 @end

ReservationsViewController.m

#import "ReservationsViewController.h"

 @interface ReservationsViewController ()
   @end

 @implementation ReservationsViewController @synthesize WebView2;

 - (void)viewDidLoad {
     [WebView2 loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@"http://www.google.be"]]];

     [super viewDidLoad];
     }


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

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

 @end

这可能无法解决您的问题，但请尝试此操作。同样更改您的PricesViewController.h和ReservationsViewController.h。此外，您使用的是什么版本的Xcode，以及您定位的iOS版本是什么？如果您使用的是最新版本的Xcode和iOS，则不应该在.m中使用@synthesize。

@interface PricesViewController : UIViewController

@property (nonatomic, weak) IBOutlet UIWebView *WebView;

@end

不应保留

IBOutlet，因为这会导致保留周期。可能不是原因，但无论如何都是良好的编程习惯。

两个uiwebview，但只有一个工作
