以阿拉伯语提交文本字段时，iOS 应用程序崩溃 [英] iOS app crashing when submitting textfield in Arabic

问题描述

我的应用是电子商务应用.当我从 iOS 添加新产品时，如果我用英文填写描述字段，它会成功发布产品，但是当我尝试使用阿拉伯语并单击提交按钮后，它会崩溃并显示 Thread 1: EXC_BAD_INSTRUCTION (code=EXC_I386_INVOP, subcode=0x0)

My app is an e-commerce app. When I add a new product from iOS if I fill the description field in English it post the product successfully, but when I try Arabic and after clicking the submit button it crashes with Thread 1: EXC_BAD_INSTRUCTION (code=EXC_I386_INVOP, subcode=0x0)

removeQuotesFromHTML 在调用时中断

removeQuotesFromHTML breaks when called

    (NSString *)removeQuotesFromHTML:(NSString *)html {
  
        html = [html stringByReplacingOccurrencesOfString:@"\"" withString:@"\\\""];
        html = [html stringByReplacingOccurrencesOfString:@""" withString:@"""];
        html = [html stringByReplacingOccurrencesOfString:@""" withString:@"""];
        html = [html stringByReplacingOccurrencesOfString:@"\r"  withString:@"\\r"];
        html = [html stringByReplacingOccurrencesOfString:@"\n"  withString:@"\\n"];
        return html;
}

第一个断点发生在下面的代码中，在 delegat.postProductArray 我认为当 getHTML 被调用时它实际上会中断

the first breakpoint happens in the following code, at delegat.postProductArray i think it actually break when getHTML is called

(void) SaveProductBtnTapped
{
    [self.view endEditing:YES];
  [delegate.postProductArray replaceObjectAtIndex:3 withObject:[self getHTML]];
      NSString * message=@"";
    if([delegate.addProductPhotos count]==0){
        message=[delegate.languageDict objectForKey:@"uploadimage"];
    }else if([[delegate.postProductArray objectAtIndex:2] isEqualToString:@""] || [[delegate.postProductArray objectAtIndex:2] isEqualToString:[delegate.languageDict objectForKey:@"what_are_you_selling"]]){
        message=[delegate.languageDict objectForKey:@"titlecannotblank"];
    }else if([[self getText] isEqualToString:@""]){
        message=[delegate.languageDict objectForKey:@"descriptioncannotblank"];
    }else if([[NSString stringWithFormat:@"%@",[delegate.postProductArray objectAtIndex:4]] isEqualToString:@""]&&!freeProduct){
        message=[delegate.languageDict objectForKey:@"pricecannotblank"];
    }
    else if([[delegate.postProductArray objectAtIndex:4]integerValue]==0&&!freeProduct)
    {
        //Entrez le prix valide
        message=[delegate.languageDict objectForKey:@"entervalidprice"];
    }
    else if([[NSString stringWithFormat:@"%@",[delegate.postProductArray objectAtIndex:5]] isEqualToString:@""]){
        message=[delegate.languageDict objectForKey:@"currencycodenotselected"];
    }else if([[NSString stringWithFormat:@"%@",[delegate.postProductArray objectAtIndex:0]] isEqualToString:@""]){
        message=[delegate.languageDict objectForKey:@"select_category"];
    }else if([[delegate.postProductArray objectAtIndex:7] isEqualToString:@""]||[[delegate.postProductArray objectAtIndex:7]isEqualToString:@"North Atlantic Ocean"]){
        message[delegate.languageDictobjectForKey:@"locationnotselected"];

调用 removeQuotesFromHTML 时出现以下中断

and the following breaks when calling removeQuotesFromHTML

(NSString *)getHTML
{
    NSString *html = [self stringByEvaluatingJavaScriptFromString:@"zss_editor.getHTML();"];
    //NSString *html = [editorView stringByEvaluatingJavaScriptFromString:@"zss_editor.getHTML();"];
    html = [self removeQuotesFromHTML:html];
    html = [self tidyHTML:html];
    return html;
}

推荐答案

试试这个:

NSString * newHTML = [NSString stringWithFormat:@"%@", html];

newHTML = [newHTML stringByReplacingOccurrencesOfString:@"\"" withString:@"\\\""];
//...... all replaces

return newHTML;
