在MKMap View中显示附近的餐厅
在我的iphone应用程序中，我必须在Map View中靠近餐馆，目前我正在使用Google地图url。
但我怎么能显示附近的餐馆与5000米的当地位置与本地MKMap视图（我发现了我的当前位置lat＆long）
我想学习如何实现在下面的屏幕截图（通过点击注解去细节）
任何帮助？ 提前致谢
在iOS 6.1中，您可以使用标准iOS MapKit.framework的一部分MKLocalSearch：
MKLocalSearchRequest *request = [[MKLocalSearchRequest alloc] init]; request.naturalLanguageQuery = @"restaurant"; request.region = mapView.region; MKLocalSearch *localSearch = [[MKLocalSearch alloc] initWithRequest:request]; [localSearch startWithCompletionHandler:^(MKLocalSearchResponse *response, NSError *error) { NSMutableArray *annotations = [NSMutableArray array]; [response.mapItems enumerateObjectsUsingBlock:^(MKMapItem *item, NSUInteger idx, BOOL *stop) { CustomAnnotation *annotation = [[CustomAnnotation alloc] initWithPlacemark:item.placemark]; annotation.title = item.name; annotation.subtitle = item.placemark.addressDictionary[(NSString *)kABPersonAddressStreetKey]; annotation.phone = item.phoneNumber; [annotations addObject:annotation]; }]; [self.mapView addAnnotations:annotations]; }];
我的自定义注释只是一个MKPlacemark加上一个标题和副标题：
@interface CustomAnnotation : MKPlacemark @property (strong, nonatomic) NSString *title; @property (strong, nonatomic) NSString *subtitle; @property (strong, nonatomic) NSString *phone; @end
如果您想要在标注上看到披露指标（以便您可以转换到其他控制器查看详细信息，则可以：
- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id<MKAnnotation>)annotation { if (![annotation isKindOfClass:[CustomAnnotation class]]) return nil; MKAnnotationView *annotationView = [[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"CustomAnnotationView"]; annotationView.canShowCallout = YES; annotationView.rightCalloutAccessoryView = [UIButton buttonWithType:UIButtonTypeDetailDisclosure]; return annotationView; }
如果您想在用户单击标注附件时打开其他视图，请执行以下操作：
- (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control { if (![view.annotation isKindOfClass:[CustomAnnotation class]]) return; CustomAnnotation *annotation = (CustomAnnotation *)view.annotation; ABRecordRef person = ABPersonCreate(); ABRecordSetValue(person, kABPersonOrganizationProperty, (__bridge CFStringRef) annotation.title, NULL); if (annotation.phone) { ABMutableMultiValueRef phoneNumberMultiValue = ABMultiValueCreateMutable(kABMultiStringPropertyType); ABMultiValueAddValueAndLabel(phoneNumberMultiValue, (__bridge CFStringRef) annotation.phone, kABPersonPhoneMainLabel, NULL); ABRecordSetValue(person, kABPersonPhoneProperty, phoneNumberMultiValue, nil); CFRelease(phoneNumberMultiValue); } ABMutableMultiValueRef address = ABMultiValueCreateMutable(kABMultiDictionaryPropertyType); ABMultiValueAddValueAndLabel(address, (__bridge CFDictionaryRef) annotation.addressDictionary, kABWorkLabel, NULL); ABRecordSetValue(person, kABPersonAddressProperty, address, NULL); ABUnknownPersonViewController *personView = [[ABUnknownPersonViewController alloc] init]; personView.unknownPersonViewDelegate = self; personView.displayedPerson = person; personView.allowsAddingToAddressBook = YES; [self.navigationController pushViewController:personView animated:YES]; CFRelease(address); CFRelease(person); } - (void)unknownPersonViewController:(ABUnknownPersonViewController *)unknownPersonView didResolveToPerson:(ABRecordRef)person { }
有关更多信息（例如，自定义注释视图，确定设备位置等），请参阅位置感知编程指南 。
看到一个简单的例子https://github.com/robertmryan/MKMapView-custom-annotations 。
使用谷歌API的结果与json或xml格式
参考这个链接
首先引用此Google API链接https://developers.google.com/places/documentation/search ，然后获取id并将其添加到googleId的参数中，只需设置具有5000值的radious参数以及types设置值餐厅。
看我的波纹pipe的例子..
NSString *str=[NSString stringWithFormat:@"https://maps.googleapis.com/maps/api/place/search/json?location=%f,%f&radius=5000&types=%@&sensor=false&key=%@",currentLocation.latitude,currentLocation.longitude,@"restaurant",@"AIzaSyB7YTFTYyk9eb8ULNGxoy06-b_0DUOqdrY"]; NSLog(@"\n\n URL %@",str); NSURL *strurl=[NSURL URLWithString:[str stringByReplacingOccurrencesOfString:@"|" withString:@"%7C"]]; // NSURL *strurl = [NSURL URLWithString:@"https://maps.googleapis.com/maps/api/place/search/json?location=-33.8670522,151.1957362&radius=500&types=food&name=harbour&sensor=false&key=AIzaSyB7YTFTYyk9eb8ULNGxoy06-b_0DUOqdrY"]; ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:strurl]; [request setDelegate:self]; [request startAsynchronous];
并在MKMapView像波纹pipe实现这些整个logging…
- (void)requestFinished:(ASIHTTPRequest *)request { // Use when fetching text data NSString *responseString = [request responseString]; NSLog(@"\n\n>>>>......Response String >>> %@",responseString); if(responseString) { SBJSON *json = [[SBJSON alloc] init]; NSError *error = nil; id result = [json objectWithString:responseString error:&error]; if ([result isKindOfClass:[NSMutableArray class]]) { NSLog(@"\n\n.......This is Mutable Array"); } else { if ([[result objectForKey:@"results"] count]>0) { NSLog(@">>>>>>>> dict keys :%d \nFull Address : %@\n LatLong : %@ \n total result : %d", [[result objectForKey:@"results"] count],[[result objectForKey:@"results"]valueForKey:@"vicinity"],[[[result objectForKey:@"results"]valueForKey:@"geometry"]valueForKey:@"location"],[[result objectForKey:@"results"]count]); for (int i=0; i<[[result objectForKey:@"results"] count]; i++) { ann = [[MyAnnotation alloc] init]; ann.title = [[[result objectForKey:@"results"]objectAtIndex:i]valueForKey:@"name"]; ann.subtitle = [[[result objectForKey:@"results"]objectAtIndex:i]valueForKey:@"vicinity"]; ann.annReferance=[[[result objectForKey:@"results"]objectAtIndex:i]valueForKey:@"reference"]; CLLocationCoordinate2D location; location.latitude = [[[[[[result objectForKey:@"results"]objectAtIndex:i]valueForKey:@"geometry"]valueForKey:@"location"] valueForKey:@"lat"]doubleValue]; location.longitude = [[[[[[result objectForKey:@"results"]objectAtIndex:i]valueForKey:@"geometry"]valueForKey:@"location"] valueForKey:@"lng"] doubleValue]; ann.coordinate=location; ann.annLocation=[NSString stringWithFormat:@"%f,%f",location.latitude,location.longitude]; // NSLog(@"\n\n rating %@",ann.annrating); if ([[[[result objectForKey:@"results"]objectAtIndex:i] allKeys] containsObject:@"rating"]) { // contains key ann.annrating=[[[[result objectForKey:@"results"]objectAtIndex:i]valueForKey:@"rating"]stringValue]; NSLog(@"\n\n rating %@",ann.annrating); } else { ann.annrating=@""; } ann.annaddress=[[[result objectForKey:@"results"]objectAtIndex:i]valueForKey:@"vicinity"]; [mapView addAnnotation:ann]; } } } } }
这是我在我的应用程序中使用的代码，只是做一些改变你的需求，你会得到输出..
我希望这对你有帮助…
