ios - Objective-c BOOL 总是传递

Question

我如何检查真假，因为这不是

 BOOL *isLoggedIn = [[NSUserDefaults standardUserDefaults] boolForKey:kSignedInBool];
BOOL *userSignedUp = [[NSUserDefaults standardUserDefaults] boolForKey:kHasUserEverSignedUpBool];

if(userSignedUp == NO || isLoggedIn == NO) { // they don't have an account so can't sign in.

    //Show the modal opening screen path

    [self performSegueWithIdentifier:@"showOpeningScreen" sender:self];

} else { //

    // We have signed up before so findNearbyamulanes
    [self performSelector:@selector(findNearByAmbulances) withObject:nil afterDelay:4.0];
}

Answer 1

您不应该使用原始数据类型的指针。

将 BOOL * 更改为 BOOL。
