場景
在下面回調(diào)函數(shù)中下斷點，當(dāng)前使用 UIWebview 加載 mp4 格式視頻時叼风，會捕捉到異常。
- (void)webView:(UIWebView *)webView didFailLoadWithError:(NSError *)error {
...
}

解決方案
可忽略此錯誤，同理還有其他同類錯誤:
-
當(dāng)網(wǎng)頁內(nèi)部鏈接跳轉(zhuǎn)時
[error.domain isEqualToString:@"NSURLErrorDomain"] && error.code == NSURLErrorCancelled -
當(dāng)網(wǎng)頁包含
appstore鏈接時[error.domain isEqualToString:@"WebKitErrorDomain"] && error.code == 102 -
當(dāng)鏈接就視頻路徑時（不影響視頻正常播放）
[error.domain isEqualToString:@"WebKitErrorDomain"] && error.code == 204
具體代碼
- (void)webView:(UIWebView *)webView didFailLoadWithError:(NSError *)error {
if ([error.domain isEqualToString:@"NSURLErrorDomain"] && error.code == NSURLErrorCancelled) {
NSLog(@"Canceled request: %@", webView.request.URL);
return;
}
else if ([error.domain isEqualToString:@"WebKitErrorDomain"] && (error.code == 102 || error.code == 204)) {
NSLog(@"ignore: %@", error);
return;
}
[ViewUtils simpleAlertView:self Title:@"error" Message:[error localizedDescription] ButtonTitle:@"sure"];
}
其他錯誤
解決上述問題時假夺，發(fā)現(xiàn)這個問題 Domain=WebKitErrorDomain Code=101 "The operation couldn’t be completed. "
原因是鏈接字符串中含未轉(zhuǎn)義的字符，比如空格斋攀、豎線已卷、百分號、中文字等淳蔼。
解決方案
// [error.domain isEqualToString:@"WebKitErrorDomain"] && error.code == 101
urlString =[urlString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSURL *url = [NSURL URLWithString:urlString];
