在我的应用程序中,我与Web服务有联系,我想创建一个加载视图,以便在每次连接开始时显示,直到它返回响应。
在我的应用程序中放置此视图的最佳位置在哪里?实现它的最佳方法是什么?
谢谢,

NSURL * url = [NSURL URLWithString:@“http://.....?WSDL”];
NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:url];
NSString *msgLength = [NSString stringWithFormat:@"%d", [soapMessage length]];
[theRequest addValue: @"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
[theRequest addValue: msgLength forHTTPHeaderField:@"Content-Length"];
[theRequest setHTTPMethod:@"POST"];
[theRequest setHTTPBody: [soapMessage dataUsingEncoding:NSUTF8StringEncoding]];
NSURLConnection *theConnection = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self];
[theConnection start];
- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data {
[webData appendData:data];
}
