Facebook FBLoginView自定義loginView按鈕互聯網問題

Question

嗨，大家好，

    I'm developing app,it having login with face book functionality.For this i have used Facebook iOS SDK 3.18.1 version. I have created custom FBLoginView with custom button.every thing work properly. I had one issue if there is no internet connectivity i need to show alert like 'network requires' but when click on custom login button it directly move to safari browser with out checking network.I have written code for check network connectivity using rechablity.When i click on facebook custom login button it directly move to safari browser for facebook login.

那么有人可以幫助我解決這個問題嗎？

這是代碼：

-(void)showFacebookLoginUI
{
    self.loginview =
    [[FBLoginView alloc] initWithReadPermissions:[NSArray arrayWithObjects:@"email",@"publish_actions",@"publish_stream",@"public_profile",@"user_about_me",@"user_hometown",@"user_location",nil]];


    if (IS_IPHONE_5) {
        self.loginview.frame = CGRectMake(80, 380, 200, 40);
    }else if(IS_IPAD){
        self.loginview.frame = CGRectMake(310, 636, 180, 100);
    }else{
       self.loginview.frame = CGRectMake(80, 330, 150, 40);
    }
    for (id obj in self.loginview.subviews)
    {
        if ([obj isKindOfClass:[UIButton class]])
        {
            UIButton * loginButton =  obj;

            UIImage *loginImage = [UIImage imageNamed:@"fbIcon.png"];
            [loginButton setBackgroundImage:loginImage forState:UIControlStateNormal];
             [loginButton setBackgroundImage:nil forState:UIControlStateSelected];
            [loginButton setBackgroundImage:nil forState:UIControlStateHighlighted];
            [loginButton addTarget:self action:@selector(fblogin:) forControlEvents:UIControlEventTouchUpInside];
        }
        if ([obj isKindOfClass:[UILabel class]])
        {
             UILabel *label =obj;
            [label removeFromSuperview];          
        }
    }

    [self.view addSubview:self.loginview];
}
-(void)fblogin:(id)sender
{

    if (![self.sharedObject CheckInternetConnectivity]) {

        [self.sharedObject showAlertWithMessage:kNetworkRequiresMessage];
    }
    else{
        self.loginview.delegate = self;
    }
}

在fblogin方法中，它可以直接導航到野生動物園瀏覽器以登錄人臉書，而無需檢查網絡連接。

如下更改您的代碼。

        loginFacebook =
        [[FBLoginView alloc] initWithPublishPermissions:[NSArray arrayWithObjects:@"email",@"user_friends",nil] defaultAudience:FBSessionDefaultAudienceFriends];

        if (IS_IPHONE_5) {
        self.loginview.frame = CGRectMake(80, 380, 200, 40);
        }else if(IS_IPAD){
        self.loginview.frame = CGRectMake(310, 636, 180, 100);
        }else{
        self.loginview.frame = CGRectMake(80, 330, 150, 40);
        }

        for (id obj in loginFacebook.subviews)
        {
            if ([obj isKindOfClass:[UIButton class]])
            {
                UIButton * loginButton =  obj;

                UIImage *loginImage = [UIImage imageNamed:@"facebook_off_signin.png"];
                [loginButton setBackgroundImage:loginImage forState:UIControlStateNormal];
                [loginButton setBackgroundImage:nil forState:UIControlStateSelected];
                [loginButton setBackgroundImage:nil forState:UIControlStateHighlighted];

                //[loginButton sizeToFit];
            }
            if ([obj isKindOfClass:[UILabel class]])
            {
                UILabel * loginLabel =  obj;
                loginLabel.text =@""; //@"Log in to facebook";
                loginLabel.textAlignment = NSTextAlignmentCenter;
                loginLabel.frame =CGRectMake(123,149, 280, 55);// CGRectMake(0, 0, 271, 37);
            }
        }

        loginFacebook.delegate = self;
      [self.view addSubview:loginFacebook];

當您單擊Facebook的Button時，您不願意添加button的Target，然后調用它的委托。

如果盡管按鈕圖像未顯示，則嘗試刪除[loginButton sizeToFit];注釋[loginButton sizeToFit]; 從代碼。 它工作。
