如何在tableview传递数据

//count duplication data in
NSMutableArray *totaluniqarray = [NSMutableArray arrayWithArray:column2Array];
orderedSet = [NSOrderedSet orderedSetWithArray:totaluniqarray];
uniqtotal = [[orderedSet set] allObjects]; 
countedSet = [[NSCountedSet alloc] initWithArray:totaluniqarray]; 
for(int i=0;i<[uniqtotal count];i++)
{ 
   NSLog(@"%@ %lu",[uniqtotal objectAtIndex:i], (unsigned long)[countedSet countForObject: [uniqtotal objectAtIndex:i]]);
}

此代码用于计数数组中的重复项。 这是输出。 我只希望countForObject显示在tableView 。

Answer 1

首先在tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section返回

return [uniqtotal count]

然后在cellForRowAtIndexPath执行以下操作：

cell.textLabel.text =[@((unsigned long)[countedSet countForObject: [uniqtotal objectAtIndex:i]]) stringValue]
