如何重新加载一个表视图行选择然后另一个tableview重新加载？

Question

以下是我的示例代码。如何重新加载tblview（tableview）？请帮帮我。

@interface NewUIViewController : UIViewController<UITableViewDataSource,UITableViewDelegate> 
@property (nonatomic, strong) NSMutableArray *dataArray; 
@property (weak, nonatomic) IBOutlet UITableView *tblview; 
- (IBAction)btnAddRow:(id)sender; 
@property (weak, nonatomic) IBOutlet UITableView *tblviewProject; 
@property (nonatomic, strong) NSMutableArray *projectArray; 
@end 
@interface NewUIViewController() 
    { } 
@end 
@implementation NewUIViewController 
- (void)viewDidLoad { 
    [super viewDidLoad]; 
    // Do any additional setup after loading the view. 
    self.dataArray = [[NSMutableArray alloc] initWithObjects:@"Tiger",@"Leopard",@"Snow Leopard",@"Lion",nil]; 
    self.projectArray = [[NSMutableArray alloc] initWithObjects:@"test1",@"test12",@"test1 Leopard",@"test13",nil];];  
    self.tblview.delegate= self; 
    self.tblview.dataSource=self; 
    self.tblviewProject.delegate= self; 
    self.tblviewProject.dataSource =self; 
    self.tblviewProject.frame = CGRectMake(50, 150, 600, 600); 
} 
-(BOOL)shouldAutorotate 
{ 
    return YES; 
} 
- (NSUInteger) supportedInterfaceOrientations 
{ 
    return (UIInterfaceOrientationMaskLandscape); 
} 
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section 
{ 
    if (tableView == self.tblview) 
    { 
    return [self.dataArray count]; 
    } 
    else if (tableView == self.tblviewProject) 
    { 
     return [self.projectArray count]; 
    } 
    return 0; 
} 
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {  
    static NSString *CellIdentifier = @"Cell";  
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; 
    if (cell == nil) { 
     cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier]; 
     cell.editingAccessoryType = YES; 
     if (tableView == self.tblview) 
     { 
      cell.textLabel.text = [self.dataArray objectAtIndex:indexPath.row]; 
     } 
     else if (tableView == self.tblviewProject) 
     { 
      cell.textLabel.text = [self.projectArray objectAtIndex:indexPath.row]; 
     }   
    } 
    return cell; 
} 
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath 
{ 
    if(tableView == self.tblviewProject) 
    {  
     NSMutableDictionary *newDic = [[NSMutableDictionary alloc] init]; 
     NSDictionary *rowchange = (NSDictionary *) [self.dataArray objectAtIndex:[self.projIndexPath intValue]]; 
     [newDic addEntriesFromDictionary:rowchange]; 
     [newDic setObject:pname forKey:project];  
     [self.tblview beginUpdates]; 
     [self.dataArray replaceObjectAtIndex:[self.projIndexPath intValue] withObject:newDic];   
     [self.tblview reloadData]; 
     [self.tblview endUpdates]; 
    } 
} 
@end  

Answer 1

在你didSelectRowAtIndexPath方法FUNC，什么pname和projIndexPath
而self.dataArray是NSString的数组，但你replaceObjectAtIndex与字典，这是不正确
我不知道你想要什么？

更新：你的功能乳宁，但并不意味着它是正确的
在Cellforrowatindexpath设置

cell.textLabel.text = [self.dataArray objectAtIndex:indexPath.row]; 

但你在self.dataArray与字典替换项目==>你认为，这在工作吗？
尝试：

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath 
{ 
    if(tableView == self.tblviewProject) 
    { 
     [self.dataArray replaceObjectAtIndex:indexPath.row withObject:self.projectArray[indexPath.row]]; 
     [self.tblview reloadData]; 
    } 
} 

并根据需要更换pnam和projIndexPath

AXXXXXXXXXXX 更新cellforrowat

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { 
    static NSString *CellIdentifier = @"Cell"; 
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; 
    if (cell == nil) { 
     cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier]; 
     cell.editingAccessoryType = YES; 
    } 
    if (tableView == self.tblview) 
    { 
     cell.textLabel.text = [self.dataArray objectAtIndex:indexPath.row]; 
    } else if (tableView == self.tblviewProject){ 
     cell.textLabel.text = [self.projectArray objectAtIndex:indexPath.row]; 
    } 
    return cell; 
} 

我的肯定，这工作，当你reloaddata的实现代码如下，细胞不为零，所以，它不是单元格的设置数据
