【iOS 开发】自定义融云选取地位页面和地位信息页面的导航栏

1. 选取地位页面

• 创立 RCLocationPickerViewController 的子类：RCDLocationViewController，能够实现自定义导航栏左右按钮

- (void)viewDidLoad {[super viewDidLoad];
    self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"自定义左按钮" style:UIBarButtonItemStyleDone target:self action:@selector(leftItemDidPressed:)];
    self.navigationItem.leftBarButtonItem.tintColor = [UIColor redColor];
    self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"自定义右按钮" style:UIBarButtonItemStyleDone target:self action:@selector(rightItemDidPressed:)];
    self.navigationController.navigationBar.barTintColor = [UIColor blueColor];
}
- (void)leftItemDidPressed:(id)sendr {[self dismissViewControllerAnimated:YES completion:nil];
}
- (void)rightItemDidPressed:(id)sendr {[super rightBarButtonItemPressed:nil];
}

• 在聊天页子类重写以下办法，并设置代理，present 到子类的对象中。

/*!
 扩大性能板的点击回调

 @param pluginBoardView 输出扩大性能板 View
 @param tag             输出扩大性能 (Item) 的惟一标示
 */
- (void)pluginBoardView:(RCPluginBoardView *)pluginBoardView clickedItemWithTag:(NSInteger)tag {switch (tag) {
           case PLUGIN_BOARD_ITEM_LOCATION_TAG: {RCDLocationViewController *vc = [[RCDLocationViewController alloc] init];
               vc.delegate = self;
               UINavigationController *navi = [[UINavigationController alloc] initWithRootViewController:vc];
               [self presentViewController:navi animated:YES completion:nil];
           }
               break;
               
           default:
               [super pluginBoardView:pluginBoardView clickedItemWithTag:tag];
               break;
       }
}

• 聊天页子类须要遵循代理 RCLocationPickerViewControllerDelegate，并实现办法：

/*!
 地理位置抉择实现之后的回调

 @param locationPicker 地理位置选取的 ViewController
 @param location       地位的二维坐标
 @param locationName   地位的名称
 @param mapScreenShot  地位在地图中的缩略图

 @discussion
 如果您须要重写地理位置抉择的界面，当抉择地理位置实现后，须要调用此回调告诉 RCConversationViewController 定位已实现，能够进一步生成地位音讯并发送。*/
- (void)locationPicker:(RCLocationPickerViewController *)locationPicker
     didSelectLocation:(CLLocationCoordinate2D)location
          locationName:(NSString *)locationName
         mapScreenShot:(UIImage *)mapScreenShot {
    RCLocationMessage *locationMessage =
    [RCLocationMessage messageWithLocationImage:mapScreenShot location:location locationName:locationName];
    [self sendMessage:locationMessage pushContent:nil];
}

1. 地位信息页面

• 创立 RCLocationViewController 的子类 LocationViewController

- (void)viewDidLoad {[super viewDidLoad];
    self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"自定义左按钮" style:UIBarButtonItemStyleDone target:self action:@selector(leftItemDidPressed:)];
    self.navigationItem.leftBarButtonItem.tintColor = [UIColor redColor];
    
    self.navigationController.navigationBar.barTintColor = [UIColor blueColor];
}
- (void)leftItemDidPressed:(id)sendr {[self dismissViewControllerAnimated:YES completion:nil];
}

• 在会话页面重写点击地位音讯的回调

/**
 *  关上地理位置。开发者能够重写，本人依据经纬度关上地图显示地位。默认应用内置地图
 *
 *  @param locationMessageContent 地位音讯
 */
- (void)presentLocationViewController:(RCLocationMessage *)locationMessageContent {
    // LocationViewController 为 RCLocationViewController 的子类
    LocationViewController *locationViewController = [[LocationViewController alloc] init];
    locationViewController.locationName = locationMessageContent.locationName;
    locationViewController.location = locationMessageContent.location;
    locationViewController.modalPresentationStyle = UIModalPresentationFullScreen;
    UINavigationController *navc = [[UINavigationController alloc] initWithRootViewController:locationViewController];
    navc.modalPresentationStyle = UIModalPresentationFullScreen;
    [self presentViewController:navc animated:YES completion:NULL];
}
