WKWebView使用中遇到的坑
1.在调试中，H5内置弹出框， 在原生中运行不弹出
解决方案：加上下面几行代码
- (void)webView:(WKWebView*)webView runJavaScriptAlertPanelWithMessage:(NSString*)message initiatedByFrame:(WKFrameInfo*)frame completionHandler:(void(^)(void))completionHandler{
UIAlertController *alertController = [UIAlertController alertControllerWithTitle:@"提示" message:message?:@"" preferredStyle:UIAlertControllerStyleAlert];
[alertControlleraddAction:([UIAlertAction actionWithTitle:@"确认" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
completionHandler();
}])];
[self presentViewController:alertController animated:YES completion:nil];
}
- (void)webView:(WKWebView*)webView runJavaScriptConfirmPanelWithMessage:(NSString*)message initiatedByFrame:(WKFrameInfo*)frame completionHandler:(void(^)(BOOL))completionHandler{
// DLOG(@"msg = %@ frmae = %@",message,frame);
UIAlertController *alertController = [UIAlertController alertControllerWithTitle:@"提示" message:message?:@"" preferredStyle:UIAlertControllerStyleAlert];
[alertControlleraddAction:([UIAlertAction actionWithTitle:@"取消" style:UIAlertActionStyleCancel handler:^(UIAlertAction * _Nonnull action) {
completionHandler(NO);
}])];
[alertControlleraddAction:([UIAlertAction actionWithTitle:@"确认" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
completionHandler(YES);
}])];
[self presentViewController:alertController animated:YES completion:nil];
}
- (void)webView:(WKWebView*)webView runJavaScriptTextInputPanelWithPrompt:(NSString*)prompt defaultText:(NSString*)defaultText initiatedByFrame:(WKFrameInfo*)frame completionHandler:(void(^)(NSString*_Nullable))completionHandler{
UIAlertController *alertController = [UIAlertController alertControllerWithTitle:prompt message:@"" preferredStyle:UIAlertControllerStyleAlert];
[alertControlleraddTextFieldWithConfigurationHandler:^(UITextField*_NonnulltextField) {
textField.text= defaultText;
}];
[alertControlleraddAction:([UIAlertAction actionWithTitle:@"完成" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
completionHandler(alertController.textFields[0].text?:@"");
}])];
[self presentViewController:alertController animated:YES completion:nil];
}
2.设置cookie ,有时候H5会获取不到
解决办法：
-(void)setTheCookieOfWebView
{
NSDictionary *dic = [NSDictionary dictionaryWithObjectsAndKeys:self.baoFu_token,@"token", nil];
NSHTTPCookieStorage *cookieStorage = [NSHTTPCookieStorage sharedHTTPCookieStorage];
//先删除Userid和isbind的cookie
[_webView evaluateJavaScript:[NSString stringWithFormat:@"document.cookie ='json=%@'",[UIViewController convertToJsonData:dic]] completionHandler:nil];
NSArray*cookieArray = [NSArrayarrayWithArray:[cookieStoragecookies]];
for(idobjincookieArray) {
[cookieStoragedeleteCookie:obj];
}
}
+(NSString*)convertToJsonData:(NSDictionary*)dict{
NSError*error;
NSData *jsonData = [NSJSONSerialization dataWithJSONObject:dict options:kNilOptions error:&error];
NSString*jsonString;
if(!jsonData) {
NSLog(@"%@",error);
}else{
jsonString = [[NSString alloc]initWithData:jsonData encoding:NSUTF8StringEncoding];
}
NSMutableString*mutStr = [NSMutableStringstringWithString:jsonString];
NSRangerange = {0,jsonString.length};
//去掉字符串中的空格
[mutStrreplaceOccurrencesOfString:@" " withString:@"" options:NSLiteralSearch range:range];
NSRangerange2 = {0,mutStr.length};
//去掉字符串中的换行符
[mutStrreplaceOccurrencesOfString:@"\n" withString:@"" options:NSLiteralSearch range:range2];
returnmutStr;
}
