我正在使用BlackRaccoon从FTP服务器下载文件。以下是代码:
- (IBAction)download:(id)sender {
downloadData = [NSMutableData dataWithCapacity: 1];
downloadFile = [[BRRequestDownload alloc] initWithDelegate: self];
downloadFile.path = @"psnewsletter.pdf";
downloadFile.hostname = @"server";
downloadFile.username = @"user";
downloadFile.password = @"pswd";
[downloadFile start];
}
它给出以下错误
2014-02-20 11:48:43.526 BlackHillPrimarySchool[2036:a0b] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[MainViewController requestFailed:]: unrecognized selector sent to instance 0xcd609f0'
任何帮助将不胜感激。
最佳答案
requestFailed:
是必须在视图控制器中实现的BRRequest
委托方法之一。
- (void)requestFailed:(BRRequest *)request {
BRRequestError *reqError = request.error;
// check the error, handle as needed.
}
我不确定您的代码是如何编译的。这是协议的必需方法。
