如何更改FBSDKLoginButton iOS 8.3 / Swift 1.2的默认设计？（fb location above 4g设置）
我目前正在开发App，我需要更改Facebook
SDK提供的Facebook按钮的默认设计。我成功地使提供的按钮透明，并将其粘贴在设计视图上方，并且效果很好（现在设计已经匹配，Facebook
SDK按钮的功能也很好）。我这样做之后出现了问题，因为按钮丢失了它的Ui效果（单击时未突出显示）。如果有人可以帮助我，请给此设计的按钮添加突出显示效果。让我们澄清一下：我已经将UIView设计为按钮，在其上面放置了一个透明的Facebook
SDK按钮，结果是我的设计形状和Facebook按钮的功能同时出现，但失去了：单击时没有突出显示效果。
答案1
小编典典我尝试了以下代码，它以正确的方式提供了功能。但是，单击按钮后，我未能给按钮赋予突出显示效果。这是代码：
{ if (FBSDKAccessToken.currentAccessToken() != nil) { // if user logged in then handleTap func will run instead of button functionality let tap = UITapGestureRecognizer(target: self, action: "handleTap:") self.btnSignUpwithFaceBook.addGestureRecognizer(tap) } else { let loginView : FBSDKLoginButton = FBSDKLoginButton() self.view.addSubview(loginView) loginView.center = self.btnSignUpwithFaceBook.center loginView.frame.size.width = self.btnSignUpwithFaceBook.frame.width loginView.frame.size.height = self.btnSignUpwithFaceBook.frame.height loginView.frame.origin.x = self.btnSignUpwithFaceBook.frame.origin.x loginView.frame.origin.y = self.btnSignUpwithFaceBook.frame.origin.y for subView in loginView.subviews { subView.removeFromSuperview() } loginView.layer.shadowColor = UIColor.clearColor().CGColor loginView.setBackgroundImage(nil, forState: UIControlState.Normal) loginView.setBackgroundImage(nil, forState: UIControlState.Application) loginView.setBackgroundImage(nil, forState: UIControlState.allZeros) loginView.setBackgroundImage(nil, forState: UIControlState.Highlighted) loginView.setBackgroundImage(nil, forState: UIControlState.Reserved) loginView.setBackgroundImage(nil, forState: UIControlState.Selected) loginView.setImage(nil, forState: UIControlState.Normal) loginView.setImage(nil, forState: UIControlState.Application) loginView.setImage(nil, forState: UIControlState.allZeros) loginView.setImage(nil, forState: UIControlState.Highlighted) loginView.setImage(nil, forState: UIControlState.Reserved) loginView.setImage(nil, forState: UIControlState.Selected) loginView.backgroundColor = UIColor.clearColor() // just for test self.btnSignUpwithFaceBook.layer.borderWidth = 1 self.btnSignUpwithFaceBook.layer.borderColor = UIColor.whiteColor().CGColor loginView.layer.backgroundColor = UIColor.clearColor().CGColor loginView.readPermissions = ["public_profile", "email", "user_friends"] loginView.delegate = self loginView.setTranslatesAutoresizingMaskIntoConstraints(false) var constX = NSLayoutConstraint(item: loginView, attribute: NSLayoutAttribute.CenterX, relatedBy: NSLayoutRelation.Equal, toItem: self.btnSignUpwithFaceBook, attribute: NSLayoutAttribute.CenterX, multiplier: 1, constant: 0) view.addConstraint(constX) var constY = NSLayoutConstraint(item: loginView, attribute: NSLayoutAttribute.CenterY, relatedBy: NSLayoutRelation.Equal, toItem: self.btnSignUpwithFaceBook, attribute: NSLayoutAttribute.CenterY, multiplier: 1, constant: 0) view.addConstraint(constY) let views = ["loginView": loginView] var constH = NSLayoutConstraint.constraintsWithVisualFormat("H:[loginView(57)]", options: NSLayoutFormatOptions(0), metrics: nil, views: views) view.addConstraints(constH) var constW = NSLayoutConstraint.constraintsWithVisualFormat("V:[loginView(281)]", options: NSLayoutFormatOptions(0), metrics: nil, views: views) view.addConstraints(constW)}实际上，主要问题是facebookLogInButton是FBSDK的自定义类，而swift并不将其视为uiButton，这就是为什么没有突出显示属性的原因。因此，我希望您的帮助人员能够找到它的要点是找到一种方法，使facebookLoginButton迅速被视为uiButton。
Android的默认样式(特别是ButtonBar和ButtonBar.Button)是如何呈现的？
在ICS按钮栏的大多数示例中,即Google工程师的这个示例：
https://gist.github.com/2357306
我看到了对这些样式的引用：
https://www.jb51.cc/tag/buttonbar/" target="_blank">buttonbarStyle"https://www.jb51.cc/tag/buttonbar/" target="_blank">buttonbarButtonStyle"
所以我打开了Android的attrs.xml,这就是我所看到的：
<!-- Style for buttons within button bars -->
<attr name="buttonbarButtonStyle" format="reference" />
<!-- Style for button bars -->
<attr name="buttonbarStyle" format="reference" />
而已.所以也许这是一种风格,对吧？这是styles.xml：
<style name="Widget.Holo.buttonbar">
<item name="android:divider">?android:attr/dividerVertical</item>
</style>
<style name="Widget.Holo.buttonbar.Button">
</style>
咦？然而Eclipse和设备能够像这样呈现它们：
那么如何获得正确的尺寸和东西呢？我需要它们的原因是我想在Gingerbread及其下面使用这种类型的按钮栏,它缺少buttonbarStyle属性.因此,他们犯了错误：
解决方法
这是因为样式继承. Widget.Holo.buttonbar也继承了“Widget.Holo”和“Widget”的所有样式.

FBSDKLoginManager.loginWithReadPermissions不在iOS上调用处理程序
简化,代码是这样的：
func login() {
NSLog("Will login with read permissions")
FBSDKLoginManager().logInWithReadPermissions(
["public_profile"],handler: {
(result: FBSDKLoginManagerLoginResult!,error: NSError!) -> Void in
NSLog("Handler is called")
})
NSLog("Returning from login")
}
调用它时,它会生成以下日志语句：
2015-05-25 11:35:07.886 MyApp[1213:646722] Will login with read permissions 2015-05-25 11:44:22.048 MyApp[1213:646722] Returning from login
(上面的语句之间的大的时间差异是由于我使用调试器来逐步执行logInWithReadPermissions的内部.没有调试器的运行不会改变行为.)
我已经在安装了Facebook原生应用程序并且我已登录的设备上试过这个,我在没有本机应用程序的设备上试过这个,我从来没有访问过Facebook.我也在模拟器上试过这个.我得到了相同的结果.
我假设这是一个同步调用,但为了以防万一,我试着在调用线程中无限期地等待 – 处理程序仍然没有被调用,并且设备上没有任何可见的事情发生.
我打开了我能找到的所有日志记录：
FBSDKSettings.setLoggingBehavior( [FBSDKLoggingBehaviorAppEvents,FBSDKLoggingBehaviorinformational,FBSDKLoggingBehaviorAccesstokens,FBSDKLoggingBehaviorUIControlErrors,FBSDKLoggingBehaviorgraphAPIDebugWarning,FBSDKLoggingBehaviorgraphAPIDebugInfo,FBSDKLoggingBehaviorNetworkRequests,FBSDKLoggingBehaviorCacheErrors,FBSDKLoggingBehaviorDeveloperErrors])
然后,在启动时,我得到这样的：

无论哪种方式,我的处理程序从未被调用,但logInWithReadPermissions函数返回正常.
我在AppDelegate中实现了以下所有内容：
func application(application: UIApplication,didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
FBSDKApplicationDelegate.sharedInstance().application(
application,didFinishLaunchingWithOptions: launchOptions)
}
func applicationDidBecomeActive(application: UIApplication) {
FBSDKAppEvents.activateApp()
}
func application(application: UIApplication,openURL url: NSURL,sourceApplication: String?,annotation: AnyObject?) -> Bool {
return FBSDKApplicationDelegate.sharedInstance().application(
application,openURL: url,sourceApplication: sourceApplication,annotation: annotation)
}
我在Info.plist中有这些行：
<array>
<dict>
<key>CFBundleURLSchemes</key>
<array>
<string>fb140xxxxxxxxxxxxx</string>
</array>
</dict>
</array>
<key>FacebookAppID</key>
<string>140xxxxxxxxxxxxx</string>
<key>FacebookdisplayName</key>
<string>MyApp</string>
我在上面遗漏了什么？如果没有,我该如何进一步调试呢？我可以打开或关闭的任何日志记录？我在XCode或Facebook方面的应用程序设置中的任何人都可以想到我可以看到的东西？
解决方法
@H_301_60@ 你说：“I tried waiting indefinitely in the calling thread — the handler is
still never called,and nothing visible is happening on the device.”
这个调用绝对不是同步的,如果你让主线程忙于紧密的等待循环,那么它将无法“回电”.
要检查的另一件事是确保您的应用程序委托也没有实现
func application(app: UIApplication,options: [String : AnyObject]) -> Bool {
如果在app delegate中实现此方法,则将忽略其他实现：
func application(application: UIApplication,annotation: AnyObject?) -> Bool
Flutter Web-悬停时如何更改Flatbutton TEXT颜色
您可以在下面复制粘贴运行完整代码
您可以使用MouseRegion的{{1}}属性
代码段
onHover工作演示
完整代码
void _incrementExit(PointerEvent details) {
setState(() {
textColor = Colors.blue;
_exitCounter++;
});
}
void _updateLocation(PointerEvent details) {
setState(() {
textColor = Colors.red;
x = details.position.dx;
y = details.position.dy;
});
}
return MouseRegion(
onEnter: _incrementEnter,onHover: _updateLocation,onExit: _incrementExit,child: FlatButton(
color: Colors.white,textColor: Colors.teal[700],//when hovered text color change
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.circular(5),对于 textButton，我们可以使用 foregroundColor 的 ButtonStyle 属性。
TextButton(
style: ButtonStyle(
foregroundColor: MaterialStateProperty.resolveWith<Color>(
(Set<MaterialState> states) {
if (states.contains(MaterialState.focused))
return Colors.red;
if (states.contains(MaterialState.hovered))
return Colors.green;
if (states.contains(MaterialState.pressed))
return Colors.blue;
return Colors.yellow; // null throus error in flutter 2.2+.
}),),onPressed: () { },child: Text('TextButton with custom overlay colors'),)
也有一个使用MouseRegion实现此功能的软件包。
https://pub.dev/packages/hovering
示例：
HoverButton(
onpressed: () {
print('test');
},color: Colors.green,hoverColor: Colors.red,hoverTextColor: Colors.blue,child: Text('test'),)
您可以像这样更改按钮样式的 foregroundColor 属性：
ElevatedButton.styleFrom().copyWith(
backgroundColor: MaterialStateProperty.resolveWith<Color?>(
(states) {
if (states.contains(MaterialState.hovered)) {
return Colors.blue;
} else if (states.contains(MaterialState.pressed)) {
return Colors.yellow;
}
return Colors.red;
},foregroundColor: MaterialStateProperty.resolveWith<Color?>(
(states) {
if (states.contains(MaterialState.hovered)) {
return Colors.green;
}
return Colors.black;
},);
