Number of rows from tableview

I was working with the tableview and I want开发者_如何学运维ed the number of rows (i.e the number of items in tableview). How can I get the number of rows, if available?

Please help me out, thanks in advance.

take a instance variable in your header file.

 - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section      {
     yourHeaderFileVariable = [noOfItemsInArray count];
     NSLog(@"total item in table %d",yourHeaderFileVariable);
     return [noOfItemsInArray count];
}

or try this

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

     NSLog(@"total item in table %d",[noOfItemsInArray count]);
     return [noOfItemsInArray count];
}

The number of rows in table view for a section is what you are returning from (NSInteger)tableView:numberOfRowsInSection:. So if you return something like [mySource count] from this method then the number of rows is [mySource count].

For example:

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
    return [data count];
}

// to get the count 
NSInteger rowCount = [data count];

Now replace [data count] with whatever calculation you have in the delegate method.

You need to implement the delegate method :

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section  
{  
return [yourArray count];  
}  

You can then show the result in the table header by using the following delegate method :

- (NSString *)tableView:(UITableView *)resultTableView titleForHeaderInSection:(NSInteger)section  
{  
    NSString *str=[NSString stringWithFormat:@"%i",[yourArray count]];  
    str=[str stringByAppendingString:@" matches"];  
    return str;  
}  

For example, if you have 7 results in the table, the header will display the text "7 matches"

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

int count; 
    count=0;
     count=[*your array name* count]; 
    NSLog(@"row count=%d",count);
return [*your array name* count];
    }

This function returns the number rows(items) in your tableview

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
    return [listOfItems count];
  }

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



        return numberOfRows;
    }
