- (void)selectRow:(NSInteger)row inComponent:(NSInteger)component animated:(BOOL)animated

Selects a row in a specified component of the picker view.

In button click event you can make use of this.

selectRow:inComponent:animated: - Helps you select particular row in the picker.
numberOfRowsInComponent: - Returns the count of rows in the particluar component.

So inorder to select the last object index, you can make use of this.

[self.pickerView selectRow:[self.pickerView numberOfRowsInComponent:0] inComponent:0 animated:NO];

You can do this using following snippet

[self.pickerView selectRow:MAX_VALUE inComponent:0 animated:NO];

where MAX_VALUE = total no. of rows in component - 1;

Enjoy Programming !!
