{
for (int i = 0; i < [self.tableview1 numberOfSections]; i++) {
for (int j = 0; j < [self.tableview1 numberOfRowsInSection:i]; j++) {
NSUInteger ints[2] = {i,j};
NSIndexPath *indexPath = [NSIndexPath indexPathWithIndexes:ints length:2];
cell = (DemoTableViewCell *)[self.tableview1 cellForRowAtIndexPath:indexPath];
//Here is your code
UIButton *btn = cell.button;
if( [[btn imageForState:UIControlStateNormal] isEqual:[UIImage imageNamed:#"checked.png"]])
{
[btn setImage:[UIImage imageNamed:#"unchecked.png"] forState:UIControlStateNormal];
// other statements
}

[btn setImage:[UIImage imageNamed:#"checked.png"] forState:UIControlStateNormal];

My question is:
1) select all option select all "checkbox" that is done but when i "uncheck" any item of them select all option also be "uncheck".
2) Not display "checbox" in image 2 UITablevieCell.
3) When i "uncheck" item3 and click again select all option deselect all "checkbox" except item3 and item3 is checked.

Answer 1

Solution to 2) Not display "checbox" in image 2 UITablevieCell
You need to create a different prototype cell with no checkbox.
Then in cellRowAtIndexPath method use that cell if button 2 was clicked
For other questions, you need to store the state of each checkbox (in array or dictionary) . Then in cellRowAtIndexPath method depending on the state of checkbox in that row, tick or untick the checkbox of the cell
1) Have NSMutableArray in your ViewController where you would store all your checkboxes state (ticked or unticked).
2) In the method that is called when checkbox is ticked/unticked, update 1 or 0 in the array like:
- (void) actionCheckbox {
self.mydata[indexPath.row] = 1; // set 0 or 1
[self.tableview reloadRowsAtIndexPath ...]; // Don't remember exact method name
}
3) In cellRowAtIndexPath,
if(self.mydata[indexPath.row] == 1) {
// tick checkbox for this row
} else {
// untick checkbox for this row
}
