Introduction to iOS Web data download and JSON parsingIn this article, I will give you an introduction to how iOS uses nsurlconnection to download data from the Web, how to parse the downloaded JSON data format, and how to display asynchronous downloads of data and imagesThe knowledge points involved:1.NSURLConnection

whether the current download operation in the download operation cache this step. Unfortunately, it is there because it has not been deleted. If there is nothing else to do, letting go, the pictures that have failed to download will never be downloaded again. Did you forget that piece of code? Look back at the code (see how good I am):if (operation) return;

/self.sumlength; self.progress.progress=progress; 73 74//1.1 points receive data. NSLog (@ "received data from the server! ---%d ", data.length); 76 77//writes data to the created empty file, but cannot use WriteToFile (overwrite) 78//To move to the tail of the file [Self.writehandle Seektoendoffile]; 80//From the current moving position, write Data bayi [Self.writehandle Writedata:data]; 82} 83 84/* 85 * When the server's data is loaded, I/connec
