我正在尝试获取要下载的组件URL列表.我正在使用NSURLConnection来获取具有此URL列表的JSON文件.在
- (void)connection:(NSURLConnection *)connection didWriteData:(long long)bytesWritten totalBytesWritten:(long long)totalBytesWritten
我写的总字节数是122239.什么时候
- (void)connectionDidFinishDownloading:(NSURLConnection *)connection destinationURL:(NSURL *)destinationURL
我正在尝试读取url数据以提取JSON文件:
NSData *data = [NSData dataWithContentsOfURL:destinationURL options:NSDataReadingUncached error:&error];
数据总是给我一个零值也有122239字节写在这个文件中,错误打印说明显示"没有这样的文件或目录"
