我正在尝试使用情节提要实现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,我没有收到任何错误,但是只有PriceViewController有效。
另一个VC生成白页……
我正在使用以下4个文件:
PriceViewcontroller.h
#import <UIKit/UIKit.h>
@interface PricesViewController : UIViewController
{
IBOutlet UIWebView *WebView; }
@property (nonatomic, retain) UIWebView *WebView;
@end
PriceViewController.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
最佳答案
这可能无法解决您的问题,但是请尝试此操作。相似地更改PricesViewController.h
和ReservationsViewController.h
。另外,您使用的是哪个版本的Xcode,以及您定位的是哪个iOS版本?如果您使用的是Xcode和iOS的最新版本,则.m中不需要@synthesize
。
@interface PricesViewController : UIViewController
@property (nonatomic, weak) IBOutlet UIWebView *WebView;
@end
不应保留
IBOutlet
,因为这可能会导致保留周期。可能不是原因,但无论如何还是好的编程习惯。
