使用参数传递URL

Question

我在这个url中传递带有一些字符串值和粗体值的url，但是当我将breakpoint放在this和I选项卡上时，它会以粗体显示这条消息exc-bad-access我给了粗体请看‘url’我想要传递的值：

[ NSInteger day,NSInteger day1,NSString *fromDate1, NSString *fromDate1,NSString *OriginCode,NSString *DestinCode]。

当我放置breakpoint时，我在url上获得了所有的值，但是当我进入breakpoint时，我的应用程序崩溃了，为什么它崩溃了？帮帮我。我哪里错了？

-(void)sendRequest

{    








   stringWithFormat:@"http://www.google.com?AvailabilitySearchInputFRSearchView%24ButtonSubmit=Search%20For%20Flights%20&AvailabilitySeast=",day,day1,DestinCode,"2011-09","2011-09",OriginCode];
   NSString *urlString = [NSString stringWithFormat:@"http://www.bookairways tickt.com/Sales/FRSearch.aspx?AvailabilitySearchInputFRSearchView%24ButtonSubmit=Search%20For%20Flights%20&AvailabilitySearchInputFRSearchView%24DropDownListMarketDay1=**%i**&AvailabilitySearchInputFRSearchView%24DropDownListMarketDay2=**%i**&AvailabilitySearchInputFRSearchView%24DropDownListMarketDestination1=**%@**&AvailabilitySearchInputFRSearchView%24DropDownListMarketMonth1=**%@**&AvailabilitySearchInputFRSearchView%24DropDownListMarketMonth2=**%@**&AvailabilitySearchInputFRSearchView%24DropDownListMarketOrigin1=**%@**&AvailabilitySearchInputFRSearchView%24DropDownListPassengerType_ADT=1&AvailabilitySearchInputFRSearchView%24DropDownListPassengerType_CHD=0&AvailabilitySearchInputFRSearchView%24DropDownListPassengerType_INFANT=0&AvailabilitySearchInputFRSearchView%24RadioButtonFlowSelector=FlightAndCar&AvailabilitySearchInputFRSearchView%24RadioButtonMarketStructure=RoundTrip&AvailabilitySearchInputFRSearchView%24discountPax=0&__EVENTARGUMENT=&__EVENTTARGET=&__VIEWSTATE=%2FwEPDwUBMGRkg4UKvNNb1NbM14%2F2n9zUxhNQ%2B%2BA%3D&errorlist=",day,day1,DestinCode,fromDate1,fromDate2,OriginCode];
   //urlString=[urlString stringByAddingPercentEscapesUsingEncoding:NSASCIIStringEncoding];
   NSURL *url = [NSURL URLWithString:urlString];
   NSLog(@"************url:%@",url);

    NSURLRequest *theRequest=[NSURLRequest requestWithURL:url
                                   cachePolicy:NSURLRequestUseProtocolCachePolicy
                                timeoutInterval:60.0];
   NSURLConnection *theConnection=[[NSURLConnection alloc] initWithRequest:theRequest delegate:self];
   if (theConnection) {
      webData = [[NSMutableData data] retain];
      NSLog(@"%@",webData);
   } else {

   }

Harish这将帮助你在创建网址检查这我们的http://wiki.akosma.com/IPhone_URL_Schemes如下

 NSString *template = @"appigotodo://com.example.xyzapp/import?name=%@&note=%@&due-date=%@&priority=%@&repeat=%@";
NSString *name = @"Buy%20some%20milk";
NSString *note = @"Stop%20on%20the%20way%20home%20from%20work.";
NSString *dueDate = @"2009-07-16";
NSString *priority = @"1";
NSString *repeat = @"101";
NSString *stringURL = [NSString stringWithFormat:template, name, note, dueDate, priority, repeat];
NSURL *url = [NSURL URLWithString:stringURL];

[UIApplication sharedApplication openURL:url]；

让你的url像这样：

NSURL *url = [NSURL URLWithString:[*yourstring* stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];

两件事：

1. 网址中有许多未用作占位符的%符号。代码中不在'**‘之间的%符号需要像这样转义：%%。换句话说，SearchInputFRSearchView%24Button应该是使用%i将整数放入字符串的。您应该改用%d。
