iOS跳转到Touch ID设置界面

1.首先去info.plist 设置：

 

2.代码

        NSURL *url = [NSURL URLWithString:@"App-Prefs:root=TOUCHID_PASSCODE"];
        if ([[UIApplication sharedApplication] canOpenURL:url])
        {
            [[UIApplication sharedApplication] openURL:url];
        }

　　

其它设置界面同理，url换成对应系统界面的参数 即可。

3.touch id 代码示例

- (void)touchID {
    LAContext *context = [[LAContext alloc]init];
    NSError *error = nil;
    if ([context canEvaluatePolicy:LAPolicyDeviceOwnerAuthenticationWithBiometrics error:&error]) {
        [context evaluatePolicy:LAPolicyDeviceOwnerAuthenticationWithBiometrics
                localizedReason:@"为了保证数据安全性，必须开启指纹认证才能使用，谢谢！"
                          reply:^(BOOL success, NSError *error) {
                              if (error) {
                                  NSLog(@"操作失败");
                              }
                              if (success) {
                                  NSLog(@"验证成功");

                              } else {
                                  NSLog(@"验证失败");
                              } 
                          }]; 
    } else {
        NSLog(@"TouchID设备不可用");
    }
}
