How to control the state of UISwitch programmatically and not by user in Objective-C?
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}
I have a UiSwitch, which I want to disable it from being on and off by user. I want to be aware when user taps on it, and change its state programmatically if I want.
This code disables the switch but makes it faded. I don't want it because I want user tap on it.
[switch setEnabled:NO];

For whatever reason you might want to do that, one way to achieve it by adding UIView over the switch and add a tap recognizer to it to handle the tap, then you can set the switch on or off programatically. Consider the code below:
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
self.switchControl = [[UISwitch alloc] initWithFrame:CGRectMake(10, 100, 0, 0 )];
[self.view addSubview:self.switchControl];
[self.switchControl setOn:YES animated:NO];
UIView *view = [[UIView alloc] initWithFrame:self.switchControl.frame];
[self.view addSubview:view];
UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(didTapSwitch)];
[view addGestureRecognizer:tap];
}
- (void)didTapSwitch {
[self.switchControl setOn:NO animated:YES];
}

{
[super touchesEnded:touches withEvent:event];
UITouch *touch = [[event allTouches] anyObject];
CGPoint touchLocation = [touch locationInView:self.view];
if (CGRectContainsPoint(self.mySwitch.frame, touchLocation)) {
[self.mySwitch setOn:!self.mySwitch.isOn];
}
}

You can do something like this, the main idea is to find coordinates of the switch. If you have your switch in a view you can use hitTest:withEvent: method instead
#import "ViewController.h"
@interface ViewController ()
@property (strong, nonatomic) IBOutlet UISwitch *mySwitch;
@end
@implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
self.mySwitch.userInteractionEnabled = NO;
}
- (void)touchesEnded:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event
{
[super touchesEnded:touches withEvent:event];
UITouch *touch = [[event allTouches] anyObject];
CGPoint touchLocation = [touch locationInView:self.view];
if (CGRectContainsPoint(self.mySwitch.frame, touchLocation)) {
[self.mySwitch setOn:!self.mySwitch.isOn];
}
}
@end
