Flutter (半年开发经验)- iOS原生导航栏、iOS主动

AppDelegate.m

/** iOS原生导航栏 */

///原生导航栏
ExpressNavigationController *nav = [[ExpressNavigationController alloc ]initWithRootViewController:controller];
 self.window.rootViewController = nav;
 [self.window makeKeyAndVisible];
///隐藏原生导航栏，因为要使用Flutter的导航栏。
 [controller.navigationController setNavigationBarHidden:YES animated:YES];

/** iOS主动通知Flutter -注册通知 */

最新微信SDK处理-universalLink配置网上一大堆

处理Flutter通知原生-图片压缩(需要image_Picker)

FlutterMethodChannel *shareChannel = [FlutterMethodChannel methodChannelWithName:@"NativeCode" binaryMessenger:controller];
    [shareChannel setMethodCallHandler:^(FlutterMethodCall * _Nonnull call, FlutterResult  _Nonnull result) {
      
      ///使用原生导航栏-跳转原生界面
      if ([call.method isEqualToString:@"Webview"]){
            ScanWebViewController *webView = [[ScanWebViewController alloc]init];
            webView.webUrl = call.arguments;
            webView.hidesBottomBarWhenPushed = YES;
            ///原生导航栏 ExpressNavigationController *nav = [[ExpressNavigationController alloc ]initWithRootViewController:controller];
            [nav pushViewController:webView animated:YES];
        }
        if ([call.method isEqualToString:@"imageEdit"]){
            //原图地址
            NSString *originalImageFile = call.arguments;
            NSData *originalImageData = [NSData dataWithContentsOfFile:originalImageFile];
            UIImage *originalImage = [UIImage imageWithData:originalImageData];
            CGFloat soriginalKB = originalImageData.length / 1024.0;
            NSLog(@"原图地址：%@,图片大小：%.2fKB",originalImageFile,soriginalKB);
            if (soriginalKB < 500){
                result(originalImageFile);
            } else{
                //处理后图片
                NSData *imageDate = [NetworkingRequest reSizeImageData:originalImage maxImageSize:0 maxSizeWithKB:500];
                UIImage *editImage = [UIImage imageWithData:imageDate];
                ///用imagePicker保存图片，返回路径
                NSString *imagePath = [FLTImagePickerPhotoAssetUtil saveImageWithOriginalImageData:originalImageData image:editImage maxWidth:[NSNumber numberWithFloat:originalImage.size.width] maxHeight:[NSNumber numberWithFloat:originalImage.size.height] imageQuality:[NSNumber numberWithInt:1]];
                //处理后图片大小
                CGFloat sizeOriginKB = imageDate.length / 1024.0;
                NSLog(@"现图地址：%@,图片大小：%.2fKB",imagePath,sizeOriginKB);
                result(imagePath);
            }
        }
    }];

Flutter端处理

static const BasicMessageChannel<dynamic> iosMessage =
const BasicMessageChannel(
"XlbBasicMessageNSDictionary_Plugin", StandardMessageCodec());

@override
void initState() {
super.initState();
iosMessage.setMessageHandler((dynamic value) {
print('收到iOS原生消息:' + value.toString());
//我原生传过来的是NSDictionary，所以Flutter用Map接收
Map dic = value;
});
}
