Reload tableview inside a UIview

问题

My table view is inside a UI View, this has been done writing codes, now i am trying to reload the data in table view but the table view is not refreshing.

The UIview and the table view declaration are as follows:

@interface
{
 IBOutlet UITableView *tabView;
}

@property (nonatomic, strong) IBOutlet * tabView
@property (nonatomic, strong) UIView * myView;   // in .m file

回答1:

Provided you have linked up the delegate and the data source methods of the table view correctly, you could just do :

[self.tableView reloadData];

Make sure you have done :

self.tableView.dataSource = self;

Ok there could be various mistakes which lead to your problem. First of all do you implement the datasource and delegate methods ?

To do so you should declare your header like this:

@interface MyClass : UIViewController<UITableViewDelegate, UITableViewDataSource> {}

Second you should hook up your tableView with those delegate/datasource methods. To do so drag&drop it in the InterfaceBuilder or in you viewDidLoad method write this:

tableView.delegate = self;
tableView.dataSource = self;

Now make sure to implement all the necessary methods:

  - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {}
  - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {}
  - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {}

If you done all this you should update your tableView like so:

[tableView reloadData];

Also check if you connected your IBOutlet UITableView *tableView; in the Interface Builder.
