有谁知道如何使用 UISearchBar 搜索 MKMapView 上的注释吗？

Question

我已经搜索了几个小时，但什么也没找到。

还有人可以告诉我他们是否知道如何将分组的 uiTableView 中的单元格链接到某个 DetailView 并将不同的单元格链接到另一个 DetailView 吗？

Answer 1

对于地图，如果这是我的注释，我会将搜索代码放在哪里。

- (void)viewDidLoad {
    [super viewDidLoad];

    [mapView setMapType:MKMapTypeStandard];
    [mapView setZoomEnabled:YES];
    [mapView setScrollEnabled:YES];


    // Central Alabama Chapter

    MKCoordinateRegion region = { {0.0, 0.0 }, { 0.0, 0.0 } }; 
    region.center.latitude = 33.45606;
    region.center.longitude = -86.83078;
    region.span.longitudeDelta = 0.01f;
    region.span.latitudeDelta = 0.01f;

    [mapView setRegion:region animated:YES]; 

    [mapView setDelegate:self];

    DisplayMap *ann = [[DisplayMap alloc] init]; 
    ann.title = @"Central Alabama Chapter";
    ann.subtitle = @"721 Hillmoor Lane Homewood, Alabama 35209"; 
    ann.coordinate = region.center; 
    [mapView addAnnotation:ann];


    // Walnut Ridge Fire Department

    MKCoordinateRegion region1 = { {0.0, 0.0 }, { 0.0, 0.0 } }; 
    region1.center.latitude = 36.11493;
    region1.center.longitude = -90.95695;
    region1.span.longitudeDelta = 0.01f;
    region1.span.latitudeDelta = 0.01f;



    DisplayMap *ann1 = [[DisplayMap alloc] init]; 
    ann1.title = @"Walnut Ridge Fire Department";
    ann1.subtitle = @"3217 Highway 67 # B, Walnut Ridge, AR"; 
    ann1.coordinate = region1.center; 
    [mapView addAnnotation:ann1];

对于 UITableView Grouped，如果我的代码如下所示，我将在哪里以及如何使用该代码：

- (void)viewDidLoad {
    [super viewDidLoad];

    //Initialize the array.
    listOfItems = [[NSMutableArray alloc] init];

    NSArray *sectionOneArray = [NSArray arrayWithObjects:@"Mission Statement", @"Become a Member", @"Bible Ministries", @"FCFi on Facebook", @"Chapter Kit (PDF)", @"Corporate Members", @"FDIC Indianapolis", @"9/11/2001", nil];

    NSArray *sectionTwoArray = [NSArray arrayWithObjects:@"About", @"Developer", nil];

    NSArray *websiteArray = [NSArray arrayWithObjects:@"FCFi Website", nil];

    [listOfItems addObject:sectionOneArray];
    [listOfItems addObject:sectionTwoArray];
    [listOfItems addObject:websiteArray];

    //Set the title
    self.navigationItem.title = @"More";
}

Answer 2

搜索注释 -

这取决于您想要如何搜索注释，如果您想按标题搜索它，那么首先使用 MKMapView 的注释属性获取所有注释 -

NSArray *arr = [mapView annotations];

for(int i=0; i<[arr count]; i++)
{ 
     MKAnnotation *ann = [arr objectAtIndex:i];
     if([ann.title isEqualToString:[searchBar text]])
     {
         //do what you want to do after getting a annotation
     }
}

UITableView -

如果您想点击单元格上的链接，然后您可以在

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath

组表中执行此操作，首先检查indexPath.section，然后检查indexPath.row。
