我正在尝试使用同步请求读取文本文件。它不起作用,但我也没有错误或警告。
有人可以告诉我我做错了吗?
NSString *url = @"http://pappons.com/test.txt" ;
NSLog(@"getHTTPData: %@" , url ) ;
NSURLResponse* response = nil;
NSURLRequest* urlRequest = [NSURLRequest requestWithURL:[NSURL URLWithString:url] cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0];
NSData* data = [NSURLConnection sendSynchronousRequest:urlRequest returningResponse:&response error:nil] ;
NSString *myString = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
NSLog( @"data: %@" , myString ) ;
输出:

传递NSError
以检查是否发生了错误
NSError *error = nil;
NSData *data = [NSURLConnection sendSynchronousRequest:urlRequest returningResponse:&response error:&error];
