This section shows you how to handle all kinds of errors when loading a table view
- Internet connection error
- Server error
- Request error
- JSON parsing error
- Data-binding error
- Validation error
ALTableView has a new delegate designed for status update <ALTableViewLoadingDelegate>.
The delegate provides two optional protocols for will/did load.
Objective-C
Swift
func willLoadTableView(with request: URLRequest!) -> URLRequest!
func didLoadTableViewWithError(_ error: Error!)
- (NSURLRequest *)willLoadTableViewWithRequest:(NSURLRequest *)request;
(void)didLoadTableViewWithError:(NSError *)error;
Set loadingDelegate to one of your objects, then implement any of those methods accordingly.
Objective-C
Swift
tableView.loadingDelegate = self
self.tableView.loadingDelegate = self;
If the error object is empty, then no error occurred.
Otherwise, you can check the error.statusCode or print out the error.localizedString to check the error details.
