当我使用以下代码打开 FBWebDialog 时，一旦打开 FBWebDialog，单击用户名文本字段，如果您旋转 iPad 设备，现在会显示键盘，FBWebDialog 不会自动旋转到横向。
[FBSession setActiveSession: [[FBSession alloc] initWithPermissions:permission] ];
[[FBSession activeSession] openWithBehavior:FBSessionLoginBehaviorForcingWebView completionHandler:^(FBSession *session, FBSessionState status, NSError *error) {
switch (status) {
case FBSessionStateOpen:
[self getMyData];
break;
case FBSessionStateClosedLoginFailed: {
NSString *errorCode = [[error userInfo] objectForKey:FBErrorLoginFailedOriginalErrorCode];
NSString *errorReason = [[error userInfo] objectForKey:FBErrorLoginFailedReason];
BOOL userDidCancel = !errorCode && (!errorReason || [errorReason isEqualToString:FBErrorLoginFailedReasonInlineCancelledValue]);
if(error.code == 2 && ![errorReason isEqualToString:@"com.facebook.sdk:UserLoginCancelled"]) {
UIAlertView *errorMessage = [[UIAlertView alloc] initWithTitle:kFBAlertTitle message:kFBAuthenticationErrorMessage delegate:nil cancelButtonTitle:kOk otherButtonTitles:nil];
[errorMessage performSelectorOnMainThread:@selector(show) withObject:nil waitUntilDone:YES];
errorMessage = nil;
}
}
break;
// presently extension, log-out and invalidation are being implemented in the Facebook class
default:
break; // so we do nothing in response to those state transitions
}
}];
以下是重现此问题的步骤：
- 打开在 iPad 应用程序中打开的 FBWebialog
- 单击用户名文本字段并显示键盘
- 现在，如果您旋转 iPad 设备，FBWebDialog 不会自动旋转到横向。
请帮我解决这个问题....
