使用UIPicker在UITableViewController中创建所需的行数

Question

I have a view with my UIPicker that will push to my UITableViewController when my start button is pressed.

I want to create a certain number of rows per section in my UITableViewController from my UIPicker .

Here is the relevant code. I'm not getting errors. My UITableViewController just doesn't have any rows in its sections. Any advice or examples on how I could get this to work would be great. Or if someone knows a better way of going about this that would be equally appreciated.

from PushView.m

    @interface WorkoutPushViewController ()
{
NSArray *_PickerData;
}

- (void)viewDidLoad {
[super viewDidLoad];

//picker
_PickerData = @[@"1",@"2",@"3",@"4",@"5",@"6",@"7",@"8",@"9",@"10"];
self.setsPicker.dataSource = self;
self.setsPicker.delegate = self;
}

from TableView.h

    @interface TableViewController : UITableViewController
    @property (nonatomic, retain) PushViewController *pushReference;
    @end

from TableView.m

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

return ([self.pushReference.setsPicker selectedRowInComponent:0]+1);
// +1 because index 0 is 1 row. 
}

Thanks!

As Nitin Gohel said: In your TableView.h

@interface TableViewController : UITableViewController
@property (nonatomic) NSInteger numberOfRows;
@end

And in your TableView.m

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
   return self.numberOfRows;
}

Don't forget to assign the value of number of rows when your start button is tapped.
