我正在使用 Xcode6-beta5 将触摸 ID 身份验证集成到我自己的应用程序中。在真实设备 iphone5s(iOS8-beta5) 上运行，使用以下代码。已经#import。
LAContext *myContext = [[LAContext alloc] init];
NSError *authError = nil;
NSString *myLocalizedReasonString = @"use touch id to unlock app";
if ([myContext canEvaluatePolicy:LAPolicyDeviceOwnerAuthenticationWithBiometrics error:&authError]) {
[myContext evaluatePolicy:LAPolicyDeviceOwnerAuthenticationWithBiometrics
localizedReason:myLocalizedReasonString
reply:^(BOOL success, NSError *error) {
if (success) {
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"success" message:@"pass auth" delegate:self cancelButtonTitle:NSLocalizedString(@"OK", @"OK button") otherButtonTitles:nil];
[alert show];
[alert release];
// User authenticated successfully, take appropriate action
} else {
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"fail" message:@"fail auth" delegate:self cancelButtonTitle:NSLocalizedString(@"OK", @"OK button") otherButtonTitles:nil];
[alert show];
[alert release];
// User did not authenticate successfully, look at error and take appropriate action
}
}];
} else {
// Could not evaluate policy; look at authError and present an appropriate message to user
}
但是当我编译并运行它显示构建失败：
