在初始加载后,我正在尝试在 Safari 中加载任何 URL。对于任何其他网页,此代码都可以正常工作:
-(BOOL)webView:(UIWebView*)webView shouldStartLoadWithRequest:(NSURLRequest*)request navigationType:(UIWebViewNavigationType)navigationType {
NSURL* url = [request URL];
if (UIWebViewNavigationTypeLinkClicked == navigationType)
{
[[UIApplication sharedApplication] openURL:url];
return NO;
}
return YES;
}
但当我访问 m.youtube.com 时,代码不再执行任何操作,YouTube 继续在 UIWebView 中加载。我在网上找不到有关此的任何信息。有什么帮助吗?
这是我的整个 .m 文件:
#import "SecondViewController.h"
@interface SecondViewController ()
@end
@implementation SecondViewController
@synthesize topLayer = _topLayer;
@synthesize layerPosition = _layerPosition;
@synthesize webView = webView;
#define VIEW_HIDDEN 260
- (void)viewDidLoad
{
[super viewDidLoad];
webView.delegate = self;
[webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@"http://m.youtube.com"]]];
[webView setBackgroundColor:[UIColor clearColor]];
[webView setOpaque:NO];
webView.scrollView.bounces = NO;
webView.scrollView.indicatorStyle = UIScrollViewIndicatorStyleWhite;
[self performSelector:@selector(makeTick)];
self->promoteImages.contentSize = CGSizeMake(1920, 101);
UIImageView *imageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"Scroll3.png"]];
[self->promoteImages addSubview:imageView];
[promoteImages setShowsHorizontalScrollIndicator:NO];
// Do any additional setup after loading the view, typically from a nib.
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType {
if (navigationType == UIWebViewNavigationTypeLinkClicked) {
[[UIApplication sharedApplication] openURL:request.URL];
return NO;
}
return YES;
}
@end
这是我的视图控制器的 .h 文件:
#import <UIKit/UIKit.h>
#import <QuartzCore/QuartzCore.h>
#import <Social/Social.h>
@interface SecondViewController : UIViewController <UIWebViewDelegate>
{
IBOutlet UIScrollView *promoteImages;
NSTimer *time;
IBOutlet UIWebView *webView;
}
@property (nonatomic, nonatomic) UIWebView *webView;
@property (weak, nonatomic) IBOutlet UIView *topLayer;
@property (nonatomic) CGFloat layerPosition;
@property(nonatomic,readonly,getter=isDragging) BOOL dragging;
