iPhone error in delete function - ios

Question

The YApp crashes whenever I press the Delete button from the simulator in iPhone. I have copied some code from my project here. How can I solve the delete bug?
I found a similar question, Error in the delete function of the alarm app in iPhone, but it does not answer my question.
My code is below.
#import "FirstPage.h"
#implementation FirstPage

Answer 1

I think the problem is in the section listed below.
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
// Return the number of rows in the section.
int count = [Array count];
if(self.editing) count++;
//return count;
return [[[UIApplication sharedApplication] scheduledLocalNotifications] count];
}
