如何使用UIWebView识别单个点击

您可以使用TouchShoulDBegin:withEvent:inContentView:UIScrollView中定义的方法 documentation .

- (BOOL)touchesShouldBegin:(NSSet *)touches withEvent:(UIEvent *)event inContentView:(UIView *)view {
// DO SOMETHING
return NO;}

@皮埃尔

@implementation UIViewTouch

. . .

- (BOOL)touchesShouldBegin:(NSSet *)touches withEvent:(UIEvent *)event inContentView:(UIView *)view 
{
    // DO SOMETHING
    return NO;
}

-(void)viewDidLoad
{

    CGRect frame = CGRectMake(0, 0, 500, 1000);     
    UIViewTouch *viewTouch = [[UIViewTouch alloc]initWithFrame:frame];

    NSString *urlAddress = [[NSBundle mainBundle] pathForResource:@"page1" ofType:@"pdf"];  
    NSURL *url = [NSURL fileURLWithPath:urlAddress];
    NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
    [viewTouch loadRequest:requestObj]; [self.view addSubview:viewTouch];

}

创建 UIView 包含整体的子类 UIWebView . 然后事件 hitTest 触动网络视图将被解雇。

@interface myWebViewContainer : UIView
... ...
@end

然后重写hitTest事件:

-(UIView*) hitTest:(CGPoint)point withEvent:(UIEvent *)event
{
    NSLog(@"Hit test %@", [event description]);
    UIView * returnView = [super hitTest:point withEvent:event];
    [delegate userDidTapWebView];// notify the delegate that UIWebView is being touched by some naughty user :P


    return  returnView;
}
