碰撞從表視圖除去細胞

Question

- (void)tableView:(UITableView *)tv commitEditingStyle:(UITableViewCellEditingStyle)editingStyle 
forRowAtIndexPath:(NSIndexPath *)indexPath { 
    if(editingStyle == UITableViewCellEditingStyleDelete) { 

     //Get the object to delete from the array. 
     NSLog(@"%@",[[_arrayForTable valueForKey:@"IDS"] objectAtIndex:[indexPath row]]); 

     NSInteger myInteger = [[[_arrayForTable valueForKey:@"IDS"] objectAtIndex:[indexPath row]] integerValue]; 
     NSNumber *selRow = [NSNumber numberWithInt:myInteger]; 
     NSLog(@"%@",selRow); 
     [self removeCell:selRow]; // this is working perfectly it gets remove from database 

     //Delete the object from the table. 
     // app get crash here crash report is pested below 
     [self.table deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade]; 

    } 
} 

- (void) removeCell:(NSNumber *)selRow{ 

     NSLog(@"_arrayForTable%@",_arrayForTable); 
NSInteger myInteger = [selRow integerValue]; 

    [_arrayForTable removeObjectAtIndex:myInteger]; 

    NSLog(@"_arrayForTable%@",_arrayForTable); 



    if(deleteStmt == nil) { 
     const char *sql = "delete from PersonNamesAndBirthDates where ID = ?"; 
     NSLog(@"%s",sql); 
     if(sqlite3_prepare_v2(database1, sql, -1, &deleteStmt, NULL) != SQLITE_OK) 
      NSAssert1(0, @"Error while creating delete statement. '%s'", sqlite3_errmsg(database1)); 
    } 
    NSLog(@"%d",myInteger); 

    //When binding parameters, index starts from 1 and not zero. 
    sqlite3_bind_int(deleteStmt, 1, myInteger); 

    if (SQLITE_DONE != sqlite3_step(deleteStmt)) 
     NSAssert1(0, @"Error while deleting. '%s'", sqlite3_errmsg(database1)); 

    sqlite3_reset(deleteStmt); 
}

請建議一些

我numberofrow方法如下

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

    // Return the number of rows in the section. 


    return _arrayForTable.count; 

} 

應用程序不崩潰每次某個作品的某個時候崩潰

Answer 1

好了，因爲我看到它，你得到一個特定行的ID有：

NSInteger myInteger = 
    [[[_arrayForTable valueForKey:@"IDS"] objectAtIndex:[indexPath row]] integerValue]; 
NSNumber *selRow = [NSNumber numberWithInt:myInteger]; 

然後，您使用的特定行的ID，因爲索引中刪除來自陣列。

NSInteger myInteger = [selRow integerValue]; 
[_arrayForTable removeObjectAtIndex:myInteger]; 

這就是事情出錯的地方。如果數組與您的TableView具有相同的順序，則需要從中刪除indexPath.row。該ID對於您的數據庫是必需的。

試試這個：

- (void)tableView:(UITableView *)tv commitEditingStyle :(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath { 
    if(editingStyle == UITableViewCellEditingStyleDelete) { 

     //Get the object to delete from the array. 
     NSLog(@"%@",[[_arrayForTable valueForKey:@"IDS"] objectAtIndex:[indexPath row]]); 

     NSInteger myInteger = [[[_arrayForTable valueForKey:@"IDS"] objectAtIndex:[indexPath row]] integerValue]; 
     NSNumber *selRow = [NSNumber numberWithInt:myInteger]; 
     NSLog(@"%@",selRow); 

     [self.table beginUpdates];   

     [self removeCell:selRow]; // this is working perfectly it gets remove from database 

     //Delete the object from the table. 
     // app get crash here crash report is pested below 
     [self.table deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade]; 

     [self.table endUpdates]; 

    } 
} 

注意的[self.table beginUpdates];和[self.table endUpdates];圍繞改變tableview的代碼行。

IT「S工作 你commitEditingStyle方法，並加入這一行

[TableViewForFirstView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade];
