是否仅为ios7调用了错误

didFailLoadWithError

仅为iOS7调用。
iOS6不调用此方法

记录的错误是：

---

错误：错误域=NSURLErrorDomain代码=-999“操作失败 无法完成。（NSURErrorDomain错误-999）。” UserInfo=0xcd0e200 {nserrorfailingurkey=bsp.gov.ph/statistics/sdds/exchrate.htm， nserrorfailingurstringkey=bsp.gov.ph/statistics/sdds/exchrate.htm}

错误代码

-999

显然是一个

URL取消请求

，但我在iOS6中使用了相同的代码，效果非常好

为什么它显示ios7的错误

---

我使用的代码是：

- (void)viewDidLoad
{
     [super viewDidLoad];                
     isFirstTime=TRUE;                

     ratesArray=[[NSArray alloc]initWithObjects:@"In",@"USD",@"JPY",@"GBP",@"HKD",@"CAD",@"SGD",@"AUD",@"SAR",@"THB",@"AED",@"CNY",@"KRW",@"EUR",@"MYR",@"TWD", nil];

     NSLog(@"rates.count = %d",ratesArray.count);
     defaults = [NSUserDefaults standardUserDefaults];
     [self loadServerData];
}
