與_tableview1我的應用程序添加SearchDisplayController後開始崩潰。 我在同一個控制器類中有兩個tableview。普萊斯提出好的建議來處理這個......

多的tableview編碼編輯：

- (void)viewDidLoad { 
appDelegate = (ShowroomLocatorAppDelegate *)[[UIApplication sharedApplication] delegate]; 

NSArray *items = [[NSArray alloc] initWithObjects: 
        @"Sydney Airport (SYD), Mascot NSW 2020, Australia", 
        @"Sydney NSW, Australia'", 
        @"Smithfield NSW 2164, Australia", 
        @"Smithfield SA 5114, Australia", 
        @"Smithfield QLD 4878, Australia", 
        nil]; 

self.allItems = items; 
[items release]; 
    self._tableView1.scrollEnabled = YES; 
_tableView1.hidden = YES; 
_tableView.hidden = YES; 
[self._tableView reloadData]; 

self._tableView.rowHeight = 80.0; 
[ self.view addSubview:_tableView] ; 
_tableView.delegate = self; 
_tableView.dataSource = self; 
_tableView1.delegate = self; 
_tableView1.dataSource = self; 
} 
- (void)viewWillAppear:(BOOL)animated 
{ 
[self._tableView reloadData]; 
[self._tableView1 reloadData]; } 


- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { 
if(tableView ==_tableView && tableView ==_tableView1 ) 
{ 
    return 1; 
} 
} 

- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section { 
if(tableView ==_tableView) 
{ 
if(section == 0) 
    return [NSString stringWithFormat:NSLocalizedString(@"ShowRooms[%d]", @"Showroom format"), [appDelegate.markers count]]; 

} 
} 



// Customize the number of rows in the table view. 
- (NSInteger)tableView:(UITableView *)tableview numberOfRowsInSection:(NSInteger)section { 

if(tableview ==_tableView) 
{ 
return [appDelegate.markers count]; 
} 
if(tableview ==_tableView1) 
{ NSInteger rows = 0; 

if ([_tableView1 
    isEqual:self.searchDisplayController.searchResultsTableView]){ 
    rows = [self.searchResults count]; 
} 
else{ 
    rows = [self.allItems count]; 
} 

return rows; 
} 
    } 

在我_tableview Web服務數據得到填補，並與地址_tableview1陣列數據得到填補..... 上述錯誤是在添加_tableview1未來.....

Answer 1

我懷疑，在viewWillAppear，你做的reloadData指定self而非self.tableView。
