自定义手机Facebook登录按钮？

Question

我成功地为web定制了登录按钮，但我怎么能为iOS做到这一点？我一直在寻找，一直没能找到任何东西。

我目前使用的是Facebook SDK 3.0，实现起来相当容易，但FBLoginView按钮的设计像拇指一样突出。我正在试图用一个动画按钮来掩盖它，并向前触摸它背后的真实Facebook按钮。

Apple会在提交时拒绝这种解决方法吗？ 必须有一个更简单的方法，不是吗？

是的，你可以通过下面的代码更改。

for (id obj in loginview.subviews) 
{ 
    if ([obj isKindOfClass:[UIButton class]]) 
    { 
     UIButton * loginButton = obj; 
     [loginButton setBackgroundColor:[UIColor blueColor]]; 
     UIImage *loginImage = [UIImage imageNamed:@"facebook_btn~ipad.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 = @"Login with facebook"; 
     loginLabel.textAlignment = NSTextAlignmentCenter; 
     loginLabel.frame = CGRectMake(0, 30, 600, 30); 
     //loginLabel.text. = [UIFont fontWithName:@"Default" size:30.0]; 
     [loginLabel setFont:[UIFont boldSystemFontOfSize:27]]; 
    } 
}

请阅读Facebook SDK中的README文件。 您必须在info.plist中添加Row - FacebookBundleName并将其命名为您的包。 然后，使用此名称将项目包添加到项目中，并放入名为“lang.lproj”的文件夹中： 例如：en.lproj - it.lproj - fr.lproj - es.lproj .... 将此文件夹您必须添加Localizable.strings文件，然后您可以本地化很多短语，如：

"FBLV:LogOutButton" = "Log Out"; 
"FBLV:LogInButton" = "Log In"; 
"FBLV:LoggedInAs" = "Logged in as: %@"; 
"FBLV:LoggedInUsingFacebook" = "Logged in using Facebook"; 
"FBLV:LogOutAction" = "Log Out"; 
"FBLV:CancelAction" = "Cancel"; 

希望它可以帮助您！

//Add the normal button then add your own image and tittle and give the action the button and use the below code in the button action.
