如何自定义FBLoginVIew? [英] How to customize FBLoginVIew?

问题描述

为了在我的 ios 应用程序中连接到 facebook，我使用来自 iOS 版 Facebook SDK.

In order to connect to facebook in my ios app i'm using FBLoginVIew from Facebook SDK for iOS.

它显示了一个不错的 FB 登录按钮，但我想使用我自己的图像和文本作为登录按钮.问题是我在任何地方都看不到如何对其进行自定义.

It shows a nice FB Login Button, but I want to use my own image and text for the login button. The problem is that I don't see anywhere how to customize that.

我设法通过覆盖 FacebookSDKResources.bundle/FBLoginView/images 中的图像来更改登录按钮背景图像，但我找不到更改登录按钮文本和位置的位置，因此它保持登录"...

I've managed to change the login button background image by overriding the images in FacebookSDKResources.bundle/FBLoginView/images, but I couldn't find where to change the login button text and position, so it's stays "Log in"...

解决方案，有人吗?

谢谢

推荐答案

答案是查看 FBLoginView 子视图，找到按钮和标签并对其进行自定义.

The answer is to go over the FBLoginView subviews, find the button and the label and customize them.

代码如下:

FBLoginView *loginview = 
[[FBLoginView alloc] initWithPermissions:[NSArray arrayWithObject:@"publish_actions"]];


loginview.frame = CGRectMake(4, 95, 271, 37);
for (id obj in loginview.subviews)
        {
            if ([obj isKindOfClass:[UIButton class]])
            {
                UIButton * loginButton =  obj;
                UIImage *loginImage = [UIImage imageNamed:@"YourImg.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 = UITextAlignmentCenter;
                loginLabel.frame = CGRectMake(0, 0, 271, 37);
            }
        }

loginview.delegate = self;

[self.view addSubview:loginview];
