Moved a toolbar -44 and now the button doesn't work

I made a toolbar over a UIDatePicker and for it to look proper I had to
move it up. After I did this the bar item stopped working and was
unresponsive.
Working fine :
UIToolbar *pickerToolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0,
-29, 320, 22)];
Not working
UIToolbar *pickerToolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0,
-44, 320, 22)];
It also doesnt work at 30, so 29 must be the stopping point
