43 | RxWebViewController* webViewController = [[RxWebViewController alloc] initWithUrl:[NSURL URLWithString:urlStr]]; 44 | [self.navigationController pushViewController:webViewController animated:YES]; 45 | 46 | ####and if you want to do some custom things with webview,just subclass it 如果你需要webview的更进一步自定义，子类化即可 47 | 48 | 49 | @interface myWebViewController : RxWebViewController 50 | 51 | //do your custom things 52 | 53 | @end 54 | 55 | 56 | ####navigation bar tint color and back button style 导航栏的颜色和返回按钮样式 57 | 58 | 59 | 导航栏中出现的 返回 和 关闭 ，均会继承你的 navigationController 中对 navigationBar 的设置，比如： 60 | 61 | UIColor* tintColor = [UIColor whiteColor]; 62 | UIColor* barTintColor = [UIColor blueColor]; 63 | self.navigationController.navigationBar.tintColor = tintColor; 64 | self.navigationController.navigationBar.barTintColor = barTintColor; 65 | [self.navigationController.navigationBar setTitleTextAttributes:@{ NSForegroundColorAttributeName:tintColor 66 | }]; 67 | 68 | 这样来自定义你的navigationBar各控件颜色，webViewController中会遵循此设置，如图 69 | ![image](http://img.hb.aicdn.com/4287d071d7fa4dd8e1276506ed904093a7489352da24-56cRLk_fw658) 70 | 71 | 72 | **也可以像微信那样在你的 navigationBar 中使用自定义的 backButtonBackgroundImage，如图** 73 | 74 | ![image](http://img.hb.aicdn.com/ab84843887791178ba8764b9bde04f4b34f338cc10f8e-1umnI5_fw658) 75 | 76 | 77 | ###Thanks 78 | 79 | ------- 80 | 81 | **I used [NJKWebViewProgress](https://github.com/ninjinkun/NJKWebViewProgress) to make navigation progress, it helps a lot** 82 | -------------------------------------------------------------------------------- /RxWebViewController/RxWebViewController.h: -------------------------------------------------------------------------------- 1 | // 2 | // RxWebViewController.h 3 | // RxWebViewController 4 | // 5 | // Created by roxasora on 15/10/23. 6 | // Copyright © 2015年 roxasora.
