We are using LAContext evaluatePolicy API to show the TouchID prompt in our App.
- If we place our finger for authentication, then we can see the TouchID prompt and it completes the authentication.
- What's even more strange is that when we can't see the pop-up window, then shake the device can make it appear.
😐
A simple project with code below:
#import "ViewController.h"
#import
@interface ViewController ()
@end
@implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
}
- (void)viewDidAppear:(BOOL)animated{
dispatch_async(dispatch_get_main_queue(), ^{
LAContext *context = [[LAContext alloc] init];
[context evaluatePolicy:LAPolicyDeviceOwnerAuthenticationWithBiometrics localizedReason:@"xxxx" reply:^(BOOL success, NSError *error) {
dispatch_async(dispatch_get_main_queue(), ^{
NSLog(@"Verify successful");
});
}];
});
}
