WKWebView提示框不顯示問題
記得,關(guān)聯(lián)wkUIdelegate，添加<WKUIDelegate>
wkWebView.UIDelegate=self;
#pragma mark =========wkUIdelegate實(shí)現(xiàn)：
- (void)webView:(WKWebView *)webView runJavaScriptAlertPanelWithMessage:(NSString *)message initiatedByFrame:(WKFrameInfo *)frame completionHandler:(void (^)(void))completionHandler {
NSLog(@"我是“警告”提示框");
NSLog(@"%@", message);
// 確定按鈕
UIAlertAction *alertAction = [UIAlertAction actionWithTitle:@"OK" style:UIAlertActionStyleCancel handler:^(UIAlertAction * _Nonnull action) {
/*
默認(rèn)為yes。completionHandler(YES),允許加載 允許用戶選擇后的操作
completionHandler(NO),不允許加載 返回用戶選擇前的操作
*/
completionHandler();
}];
// alert彈出框
UIAlertController *alertController = [UIAlertController alertControllerWithTitle:message message:nil preferredStyle:UIAlertControllerStyleAlert];
[alertController addAction:alertAction];
[self presentViewController:alertController animated:YES completion:nil];
}
#pragma mark Confirm選擇框
- (void)webView:(WKWebView *)webView runJavaScriptConfirmPanelWithMessage:(nonnull NSString *)message initiatedByFrame:(nonnull WKFrameInfo *)frame completionHandler:(nonnull void (^)(BOOL))completionHandler {
NSLog(@"我是 選擇 提示框");
NSLog(@"%@", message);
// 按鈕
UIAlertAction *alertActionCancel = [UIAlertAction actionWithTitle:@"取消" style:UIAlertActionStyleCancel handler:^(UIAlertAction * _Nonnull action) {
// 返回用戶選擇前的信息
completionHandler(NO);
}];
UIAlertAction *alertActionOK = [UIAlertAction actionWithTitle:@"確定" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
completionHandler(YES);
}];
// alert彈出框
UIAlertController *alertController = [UIAlertController alertControllerWithTitle:message message:nil preferredStyle:UIAlertControllerStyleAlert];
[alertController addAction:alertActionCancel];
[alertController addAction:alertActionOK];
[self presentViewController:alertController animated:YES completion:nil];
}
#pragma mark TextInput輸入框
- (void)webView:(WKWebView *)webView runJavaScriptTextInputPanelWithPrompt:(nonnull NSString *)prompt defaultText:(nullable NSString *)defaultText initiatedByFrame:(nonnull WKFrameInfo *)frame completionHandler:(nonnull void (^)(NSString * _Nullable))completionHandler {
NSLog(@"我是輸入提示框3");
NSLog(@"%@", message);
// alert彈出框
UIAlertController *alertController = [UIAlertController alertControllerWithTitle:prompt message:nil preferredStyle:UIAlertControllerStyleAlert];
// 輸入框
[alertController addTextFieldWithConfigurationHandler:^(UITextField * _Nonnull textField) {
textField.placeholder = defaultText;
}];
// 確定按鈕
[alertController addAction:[UIAlertAction actionWithTitle:@"確定" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
// 返回用戶輸入的信息
UITextField *textField = alertController.textFields.firstObject;
completionHandler(textField.text);
}]];
// 顯示
[self presentViewController:alertController animated:YES completion:nil];
