我必須做SSL固定,因此需要驗證服務器端SSL證書。 所以我必須使用NSURL代表。我在我所創建方法的輔助類返回我登錄響應:NSUrlConnection委託方法沒有從幫助類中調用
- (NSData *)sendSynchronousRequest:(NSString *)strNewLoginRequest
returningResponse:(NSURLResponse **)response
error:(NSError **)error {
NSMutableURLRequest *finalRequest = nil;
NSURL *url= [NSURL URLWithString:const_url];
finalRequest = [NSMutableURLRequest requestWithURL:url cachePolicy:NSURLRequestReloadIgnoringCacheData timeoutInterval:30.0];
NSData *requestData = [NSData dataWithBytes:[strLoginRequest UTF8String] length:[strLoginRequest length]];
self.connection = [[NSURLConnection alloc] initWithRequest:finalRequest delegate:self startImmediately:NO];
NSRunLoop *currentRunLoop = [NSRunLoop currentRunLoop];
[self.connection unscheduleFromRunLoop:currentRunLoop forMode:NSDefaultRunLoopMode];
[self.connection scheduleInRunLoop:currentRunLoop forMode:@"connectionRunLoopMode"];
[self.connection start];
while ([currentRunLoop runMode:@"connectionRunLoopMode" beforeDate:[NSDate distantFuture]]);
return self.mutableResponse;
}
- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response
{
self.response = response;
}
- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
{
self.mutableResponse = [[NSMutableData alloc]init];
[self.mutableResponse appendData:data];
}
- (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error
{
dispatch_async(dispatch_get_main_queue(), ^{
if (loadingView)
{
[loadingView removeView];
}
UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"Failure" message:@"Network Failure" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil, nil];
[alert show];
});
}
- (void)connectionDidFinishLoading:(NSURLConnection *)connection
{
if (loadingView)
{
[loadingView removeView];
}
self.resultString = [[NSString alloc] initWithData:self.mutableResponse encoding:NSASCIIStringEncoding];
}
和我打電話從所謂的ViewController與代碼另一類這個方法
-(void)doLogin
{
self.service = [[SyncCommunicationService alloc]init];
NSData *data = [self.service sendSynchronousRequest:strNewLoginRequest
returningResponse:&response
error:nil];
}
我試圖調用此方法在後臺和主線程,但仍然委託方法沒有得到調用,我已經嘗試了許多來自同一網站的其他答案,但仍然無法解決這個問題,所以請任何人有線索我做錯了什麼。
我必須驗證服務器證書的SSL固定,所以我必須使用委託方法。 – Vaibhav
在這種情況下,嘗試設置連接委託隊列'setDelegateQueue:' 讓此隊列屬於您的SyncCommunicationService –
並且,您對'while'語句是否有信心等待操作?爲什麼不使用dispatch_semaphore呢?比你的'sendSynchronousRequest:returningResponse:error:'方法不會返回任何內容,並且可以從SyncCommunicationService的屬性中檢索響應數據(這就是我每次都在做的事情,我需要異步檢索數據) –
