Local Declaration Hides Instance Variable - tableView Not Synthesized

I have read about using underscores to fix compiler warnings that say "Local declaration hides instance variable," but I have not been able to implement a fix. The solutions I have read about say to use an underscore in my .h file, and the @synthesize part of in my .m file. However, I do not synthesize my tableView. Please see my header file below:

.h File

@interface ListViewController : GAITrackedViewController <UISearchDisplayDelegate, 
UISearchBarDelegate, UITableViewDataSource, UITableViewDelegate> {

IBOutlet UITableView *tableView;

}

.m File

//SYNTHESIZE
@synthesize listItems, filteredListItems, savedSearchTerm, savedScopeButtonIndex, 
searchWasActive, mapView, loadingImageView, loadingActivity;



- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {

 //FIRST WARNING for tableView HERE

if (tableView == self.searchDisplayController.searchResultsTableView){
    return [self.filteredListItems count];
    }
    else{
        return [self.listItems count];
    }
}

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {

    //SECOND WARNING for tableView HERE

    [tableView setRowHeight: 60.00];
    return 1;

}

I do also spent lot of time on this issue. Finally I could solve this problem. The thing is we should take care of outlets which are created by us. If you change outlets names then you must connect them properly after change.In my case after lot of struggle I could finish this issue hope it will help others.... For example if You have an outlet/property named tableView and your delegate method also contains tableView.

So you need to change either of them. Typically you go to change the argument names of delegate and datasource as Change :

IBOutlet UITableView *tableView;

To :

IBOutlet UITableView *tableView1;

Change :

IBOutlet UITableView *tableView;

To :

IBOutlet UITableView *tableView1;

Make the same required changes in your .m file also. This warning is coming because in below delegate method:

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section

There is a reference of UITableView with name tableView and you have given the same name. Scope of this variable is function level where as scope of your variable declare in .h is class level.
