uipickerview

I Have an a touchesEnded event that checks for when a UITextField is pressed. What I would like it to do is is hide/show a UIPickerView. How can this be done? - (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event{ UITouch *touch = [[event allTouches] anyObject]; if (CGRectContainsPoint([self.textField frame], [touch locationInView:self.view])) { NSString * error = @"Touched the TextField"; UIAlertView * errorAlert = [[UIAlertView alloc] initWithTitle:@"Selection!" message:error delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil]; [errorAlert show]; //Want to show or hide

I am having a UIPicker, I want to change the color of the selector. Is it possible to change the color of the selector? I suppose you're dealing with the iPhone SDK? There may be some other frameworks which uses this name, so maybe you can add your tags to include uikit, cocoa-touch or something. Anyway, you can set showsSelectionIndicator of the UIPickerView instance to NO, so it hides the selector. Then you can create a new view with the adjusted selection style, and add it to the superview above the UIPickerView. // Some sample code, but you can do this in IB if you want to _pickerView = [
