ある種のクラッシュが発生しました。クラッシュ スタックは次のとおりです。

および 2 つのコード:

- (void)prepareReaderInWebView:(UIWebView *)webView
{ 
// ...omit some code here

    if ([readableContent length]) {
        self.innerWebView = [[[SeMobWebInternalView alloc] initWithFrame:webView.bounds] autorelease];
        innerWebView.scalesPageToFit = NO;
        innerWebView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
        innerWebView.scrollView.backgroundColor = [UIColor colorWithWhite:0 alpha:0.3];
        innerWebView.scrollView.scrollsToTop = YES;
        innerWebView.delegate = self;
        ...
    }


@interface SeMobWebInternalView : UIWebView
- (id)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if (self) {
    // Initialization code
    UIMenuItem *flag =
    [[UIMenuItem alloc] initWithTitle:@"search" action:@selector(search:)];
    ...
}

クラッシュは常にスーパーの init メソッドで発生します。なぜいつもクラッシュするのですか？助けてください！

@cosmin が述べたように、UIWebView をサブクラス化するつもりはありません。コードからは、外観をカスタマイズしようとしているように見えます。代わりにこのコードを試してください:

webView.backgroundColor = [UIColor clearColor]; // changes to clear colour
webView.opaque = NO;

for(UIView *innerView in [[[webView subviews] objectAtIndex:0] subviews]) { // Hide images that make shadow
     if ([innerView isKindOfClass:[UIImageView class]]) {
         innerView.hidden = YES;
     }
}
