布局第一个控件
-
VFL
字典中的V和H一定要大写let dict : [String:AnyObject] = ["iconView":iconView,"loginView":loginBTN] iconView.translatesAutoresizingMaskIntoConstraints = false addConstraint(NSLayoutConstraint(item: iconView, attribute: NSLayoutAttribute.CenterX, relatedBy: NSLayoutRelation.Equal, toItem: self, attribute: NSLayoutAttribute.CenterX, multiplier: 1, constant: 0)) addConstraint(NSLayoutConstraint(item: iconView, attribute: NSLayoutAttribute.CenterY, relatedBy: NSLayoutRelation.Equal, toItem: self, attribute: NSLayoutAttribute.CenterY, multiplier: 1, constant: 0)) loginBTN.translatesAutoresizingMaskIntoConstraints = false addConstraints(NSLayoutConstraint.constraintsWithVisualFormat("V:[iconView]-(10)-[loginView]", options: [], metrics: nil, views:dict )) 背景颜色

首页动画
//lazy必须要用计算属性 有等号 = 就是计算属性 //并且 在尾部要加() private lazy var iconView : UIImageView = { let imageView = UIImageView(image: UIImage(named: "visitordiscover_feed_image_smallicon")) let anim = CABasicAnimation(keyPath: "transform.rotation") anim.toValue = 2 * M_PI anim.repeatCount = MAXFLOAT anim.duration = 20 //不让动画释放 anim.removedOnCompletion = false imageView.layer.addAnimation(anim, forKey: nil) return imageView }() 不同控制器显示不同图片
在visitor中创建loadInfo 方法 为外部提供修改内部字和图片的方法
在baseController中 添加visitor属性
每个一级控制器添加loadInfo方法,并赋值监听方法
给两个按钮添加代理 监听方法-
加载oauth视图
加载oauth的网址 放在网络工具类中,定义一个属性
var authURL : NSURL {
let url = "https://api.weibo.com/oauth2/authorize?client_id=(clientId)&redirect_uself.self.ri=(redirectUri)"return NSURL(string: url)! } 封装AFN
-
自动填充
// 自动填充用户信息
@objc private func autoFill() {
let js = "document.getElementById('userId').value = 'xxxxxxxx@sina.cn';" +
"document.getElementById('passwd').value = 'xxxxxx';"webView.stringByEvaluatingJavaScriptFromString(js) } -
实现代理方法，跟踪重定向 URL
返回**<NSMutableURLRequest: 0x7fca5ae4a4a0> { URL: https://api.weibo.com/oauth2/authorize?client_id=2075091997&redirect_uri=http://www.baidu.com }** **<NSMutableURLRequest: 0x7fca5d0545e0> { URL: https://api.weibo.com/oauth2/authorize }** **<NSMutableURLRequest: 0x7fca5af41e00> { URL: https://api.weibo.com/oauth2/authorize# }** **<NSMutableURLRequest: 0x7fca5add0950> { URL: https://api.weibo.com/oauth2/authorize }** **<NSMutableURLRequest: 0x7fca5aead420> { URL: http://www.baidu.com/?code=76a5c99f5e12685e18f760679eaff44a }** **<NSMutableURLRequest: 0x7fca5aebef80> { URL: https://m.baidu.com/?code=76a5c99f5e12685e18f760679eaff44a&from=844b&vit=fps }** **<NSMutableURLRequest: 0x7fca5d123d00> { URL: about:blank }**
可以发现code后面就是accesstoken
获取请求码
func webView(webView: UIWebView, shouldStartLoadWithRequest request: NSURLRequest, navigationType: UIWebViewNavigationType) -> Bool {
let urlString = request.URL!.absoluteString
//1.判断URL开头是否是回调地址,如果是 则继续加载
if !urlString.hasPrefix(NetworkingTools.sharedTools.redirectUri){
return true
}
//2.是回调地址,截取code
//query是回调URL 问号后面的所有字符串
if let query = request.URL!.query where query.hasPrefix("code=") {
let code = query.substringFromIndex("code=".endIndex)
print(code)
}else
{
//取消
}
return false
}
-
accesstoken
得到code后 再发送给服务器 得到accesstoken
在网络工具类中写loadaccestokenfunc loadAccessToken(code : String)->RACSignal{ let urlstring = "https://api.weibo.com/oauth2/access_token" let param = ["client_id": clientId, "client_secret": appSecret, "grant_type": "authorization_code", "code": code, "redirect_uri": redirectUri] //提交 参数 用post return request(.post, urlString: urlstring, param: param) }
在oauth控制器中 订阅信号
func webView(webView: UIWebView, shouldStartLoadWithRequest request: NSURLRequest, navigationType: UIWebViewNavigationType) -> Bool {
let urlString = request.URL!.absoluteString
//1.判断URL开头是否是回调地址,如果是 则继续加载
if !urlString.hasPrefix(NetworkingTools.sharedTools.redirectUri){
return true
}
//2.是回调地址,截取code
//query是回调URL 问号后面的所有字符串
if let query = request.URL!.query where query.hasPrefix("code=") {
let code = query.substringFromIndex("code=".endIndex)
print(code)
//发送请求 获取accesstoken
//订阅信号
NetworkingTools.sharedTools.loadAccessToken(code).subscribeNext({ (result) -> Void in
print(result)
//成功获得accesstoken
}, error: { (error) -> Void in
print(error)
})
