[IOS development] Customize the navigation bar of the Rongyun selection location page and location information page
- Select location page
- Create a subclass of RCLocationPickerViewController: RCDLocationViewController, you can customize the left and right buttons of the navigation bar
- (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];
}
- Override the following methods in the chat page subclass, and set the proxy to present to the object of the subclass.
/*!
扩展功能板的点击回调
@param pluginBoardView 输入扩展功能板View
@param tag 输入扩展功能(Item)的唯一标示
*/
- (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;
}
}
-
The chat page subclass needs to follow the proxy RCLocationPickerViewControllerDelegate and implement the method:
/*! 地理位置选择完成之后的回调 @param locationPicker 地理位置选取的ViewController @param location 位置的二维坐标 @param locationName 位置的名称 @param mapScreenShot 位置在地图中的缩略图 @discussion 如果您需要重写地理位置选择的界面,当选择地理位置完成后,需要调用此回调通知RCConversationViewController定位已完成,可以进一步生成位置消息并发送。 */
- (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];
}
2. 位置信息页面
- 创建 RCLocationViewController 的子类LocationViewController
```objective-c
- (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];
}
- Override the callback of the click location message on the conversation page
/**
- Open geographic location. Developers can rewrite and open the map to display the location based on the latitude and longitude. Use built-in map by default
- @param locationMessageContent location message
*/- (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];
}
- (void)presentLocationViewController:(RCLocationMessage )locationMessageContent {
