阿新 • • 發佈：2019-02-07
一.先前準備
這就是公司的需求,上面欄目點選重新整理地圖標註,類目二根據類目一的變化而變化,標註可點選進個人資料,點選下單也可跳轉.
1.2).在用到的vc匯入,還有遵循協議<MAMapViewDelegate>,這裡還要謝謝簡書一位仁兄,因為最後兩個檔案我也是參考他的
二.上程式碼 2.1).先定義一些需要用到的小寶寶
2.2).viewDidLoad裡的幾個方法
實現這幾個方法:
2.2.1).- (void)initMapView { [AMapServices sharedServices].apiKey = @"你的key"; self.mapView = [[MAMapView alloc] initWithFrame:CGRectMake(0, 64+60, CGRectGetWidth(self.view.bounds), self.view.bounds.size.height-64-60)]; self.mapView.delegate = self; self.mapView.showsCompass = NO; self.mapView.showsScale = NO; self.mapView.zoomLevel = 17; self.mapView.showsUserLocation = YES; [self.view addSubview:self.mapView]; self.isLocated = NO; } 2.2.2).- (void)initSearch { self.searchPage = 1; //c6375c001facf8ec415c6b087ba4a364 [AMapServices sharedServices].apiKey = @"你的key"; self.search = [[AMapSearchAPI alloc] init]; } 2.2.3).- (void)initRedWaterView { self.redWaterView = [[UIView alloc]initWithFrame:CGRectMake((kScreenWidth-60)/2, self.mapView.bounds.size.height/2-50, 60, 60)]; self.redWaterView.center = CGPointMake(CGRectGetWidth(self.view.bounds) / 2, CGRectGetHeight(self.mapView.bounds) / 2 - CGRectGetHeight(self.redWaterView.bounds) / 2); self.redWaterView.backgroundColor = kAppClearColor; UIImage *image = [UIImage imageNamed:@"[email protected]"]; UIImageView *ImageV = [[UIImageView alloc]initWithFrame:CGRectMake((60-image.size.width)/2, 30, image.size.width, image.size.height)]; ImageV.image = image; UIButton *BTn = [UIButton buttonWithType:UIButtonTypeCustom]; BTn.frame = CGRectMake(0, 0, 60, 25); BTn.layer.cornerRadius = 10; BTn.layer.masksToBounds = YES; BTn.backgroundColor = kAppGoodColor; [BTn setTitle:@"點選下單" forState:UIControlStateNormal]; [BTn setTitleColor:kAppWhiteColor forState:UIControlStateNormal]; BTn.titleLabel.font = [UIFont systemFontOfSize:13]; [BTn addTarget:self action:@selector(AddOrder:) forControlEvents:UIControlEventTouchUpInside]; [self.redWaterView addSubview:BTn]; [self.redWaterView addSubview:ImageV]; [self.view addSubview:self.redWaterView]; } 2.2.4).- (void)initLocationButton //這是左下角的定位按鈕 { self.imageLocated = [UIImage imageNamed:@"[email protected]"]; self.imageNotLocate = [UIImage imageNamed:@"[email protected]"]; self.locationBtn = [[UIButton alloc] initWithFrame:CGRectMake(CGRectGetWidth(self.mapView.bounds)*0.8+10, CGRectGetHeight(self.mapView.bounds)*0.8+64, 40, 40)]; self.locationBtn.autoresizingMask = UIViewAutoresizingFlexibleTopMargin; self.locationBtn.backgroundColor = [UIColor colorWithRed:239.0/255 green:239.0/255 blue:239.0/255 alpha:1]; self.locationBtn.layer.cornerRadius = 3; [self.locationBtn addTarget:self action:@selector(actionLocation) forControlEvents:UIControlEventTouchUpInside]; [self.locationBtn setImage:self.imageNotLocate forState:UIControlStateNormal]; [self.view addSubview:self.locationBtn]; }
2.3).一些協議方法和自己定義的方法
/* 移動視窗彈一下的動畫 */
- (void)redWaterAnimimate
{
[UIView animateWithDuration:0.5
delay:0
options:UIViewAnimationOptionCurveEaseOut
animations:^{
CGPoint center = self.redWaterView.center;
center.y -= 20;
[self.redWaterView setCenter:center];}
completion:nil];
[UIView animateWithDuration:0.45
delay:0
options:UIViewAnimationOptionCurveEaseIn
animations:^{
CGPoint center = self.redWaterView.center;
center.y += 20;
[self.redWaterView setCenter:center];}
completion:nil];
}
#pragma mark - Utility
/* 根據中心點座標來搜周邊的POI. */
- (void)searchPoiByCenterCoordinate:(CLLocationCoordinate2D )coord
{
AMapPOIAroundSearchRequest*request = [[AMapPOIAroundSearchRequest alloc] init];
request.location = [AMapGeoPoint locationWithLatitude:coord.latitude longitude:coord.longitude];
request.radius = 500;//自己定義搜尋半徑
request.sortrule = 1;
request.page = self.searchPage;
[self.search AMapPOIAroundSearch:request];
}
- (void)searchReGeocodeWithCoordinate:(CLLocationCoordinate2D)coordinate
{
AMapReGeocodeSearchRequest *regeo = [[AMapReGeocodeSearchRequest alloc] init];
regeo.location = [AMapGeoPoint locationWithLatitude:coordinate.latitude longitude:coordinate.longitude];
regeo.requireExtension = YES;
[self.search AMapReGoecodeSearch:regeo];
}
#pragma mark - MapViewDelegate
- (void)mapView:(MAMapView *)mapView regionDidChangeAnimated:(BOOL)animated
{
if (!self.isMapViewRegionChangedFromTableView && self.mapView.userTrackingMode == MAUserTrackingModeNone)
{
[self searchReGeocodeWithCoordinate:self.mapView.centerCoordinate];
[self searchPoiByCenterCoordinate:self.mapView.centerCoordinate];
self.searchPage = 1;
[self redWaterAnimimate];
}
self.isMapViewRegionChangedFromTableView = NO;
}
#pragma mark - userLocation
- (void)mapView:(MAMapView *)mapView didUpdateUserLocation:(MAUserLocation *)userLocation updatingLocation:(BOOL)updatingLocation
{
if(!updatingLocation)
return ;
if (userLocation.location.horizontalAccuracy < 0)
{
return ;
}
// only the first locate used.
if (!self.isLocated)
{
self.isLocated = YES;
[self.mapView setCenterCoordinate:CLLocationCoordinate2DMake(userLocation.location.coordinate.latitude, userLocation.location.coordinate.longitude)];
NSLog(@"latitude : %f,longitude: %f",userLocation.location.coordinate.latitude, userLocation.location.coordinate.longitude);
}
}
- (void)mapView:(MAMapView *)mapView didChangeUserTrackingMode:(MAUserTrackingMode)mode animated:(BOOL)animated
{
if (mode == MAUserTrackingModeNone)
{
[self.locationBtn setImage:self.imageNotLocate forState:UIControlStateNormal];
}
else
{
[self.locationBtn setImage:self.imageLocated forState:UIControlStateNormal];
}
}
- (void)mapView:(MAMapView *)mapView didFailToLocateUserWithError:(NSError *)error
{
//NSLog(@"error = %@",error);
}
#pragma mark - Handle Action
- (void)actionLocation
{
if (self.mapView.userTrackingMode == MAUserTrackingModeFollow)
{
[self.mapView setUserTrackingMode:MAUserTrackingModeNone animated:YES];
}
else
{
self.searchPage = 1;
[self.mapView setCenterCoordinate:self.mapView.userLocation.coordinate animated:YES];
dispatch_after(dispatch_time(DISPATCH_TIME_NOW, 0.5 * NSEC_PER_SEC), dispatch_get_main_queue(), ^{
[self.mapView setUserTrackingMode:MAUserTrackingModeFollow animated:YES];
});
}
}
2.4).獲取資料以及生成UI
-(void)createData
{根據介面獲取到類目資料 生成UI [self createUI]}
實現這個方法,就是上面類目UI的實現
-(void)createUI
{
FbwManager *Manger = [FbwManager shareManager];
for (NSDictionary *dic in _TwoDataArray[0]) {//資料已經獲取到
[_DataArray2 addObject:dic[@"name"]];
[_DataArray2Id addObject:dic[@"id"]];
}
__weak __typeof(self)weakSelf = self;
UIScrollView *topScrollView = [[UIScrollView alloc]init];
[self.view addSubview:topScrollView];
[topScrollView mas_makeConstraints:^(MASConstraintMaker *make) {
make.top.equalTo(@64);
make.left.equalTo(weakSelf.view);
make.right.equalTo(@0);//make.right.equalTo(@-30);
make.height.equalTo(@30);//make.height.equalTo(@30);
}];
topScrollView.backgroundColor = kAppGoodColor;
topScrollView.contentSize = CGSizeMake(_OneDataArray.count * (kScreenWidth-30)/4.f, 0);
UIButton *_lastBtn;
NSInteger i = 0;
for (NSString *title in _OneDataArray) {
UIButton *btn = [UIButton buttonWithType:UIButtonTypeCustom];
btn.frame = CGRectMake(_lastBtn ? _lastBtn.right : 0, 0, (kScreenWidth-30)/4.f, 30);
[topScrollView addSubview:btn];
// [btn mas_makeConstraints:^(MASConstraintMaker *make) {
// make.left.equalTo(_lastBtn ? _lastBtn.mas_right : @0);
// make.top.bottom.equalTo(topScrollView);
// make.width.equalTo(@((kScreenWidth-30)/4.f));
// }];
btn.backgroundColor = kAppClearColor;
[btn setTitleColor:kAppWhiteColor forState:UIControlStateNormal];
[btn setTitle:title forState:UIControlStateNormal];
btn.titleLabel.font = [UIFont boldSystemFontOfSize:14];
[btn addTarget:self action:@selector(btnAction:) forControlEvents:UIControlEventTouchUpInside];
_lastBtn = btn;
i++;
btn.tag = 10+i;
if (btn.tag == 11) {
}}
UIScrollView *bottomScrollView = [[UIScrollView alloc]init];
[self.view addSubview:bottomScrollView];
[bottomScrollView mas_makeConstraints:^(MASConstraintMaker *make) {
make.top.equalTo(topScrollView.mas_bottom);
make.left.right.equalTo(weakSelf.view);
make.height.equalTo(@30);
}];
bottomScrollView.backgroundColor = [UIColor colorWithRed:230/255.f green:230/255.f blue:230/255.f alpha:1];
bottomScrollView.tag = 101;
[self createBottomViewWithArray:_DataArray2];//類目二根據類目一生成
[self createMapAnni];//生成標註
if (_DataArray2.count != 0) {
Manger.YueOrderName = _DataArray2[0];
}
if (_DataArray2Id.count != 0) {
Manger.YueOrderId = _DataArray2Id[0];
}
}
2.4.1).標註的生成以及實現過程
-(void)createMapAnni
{
//根據你的定位座標和設定的搜尋半徑以及類目的ID獲取到該類目下的使用者 獲取到資料 呼叫[self initAnnotations];
}
-(void)initAnnotations{
NSMutableArray *coordinates = [NSMutableArray array];}
for (int i = 0; i < _dataArray.count; i++)
{
ThirdMcModel *model = _dataArray[i];
// MAPointAnnotation *a1 = [[MAPointAnnotation alloc] init];
// a1.coordinate = CLLocationCoordinate2DMake([model.UserX doubleValue],[model.UserY doubleValue]);
// [coordinates addObject:a1];
HQMCustomAnnotation *femaleAnn = [[HQMCustomAnnotation alloc] init];//此方法參考了一位簡書的同仁 很好用,下面會給該檔案的.h .m
femaleAnn.type = CustomAnnotationTypeFemale;
femaleAnn.imagePath = model.UserPic;
femaleAnn.coordinate = CLLocationCoordinate2DMake([model.UserX doubleValue],[model.UserY doubleValue]);
[coordinates addObject:femaleAnn];
}
[self.mapView addAnnotations:coordinates];
- (MAAnnotationView *)mapView:(MAMapView *)mapView viewForAnnotation:(id)annotation//這個方法也少不了 匹配模型資料
{
if ([annotation isKindOfClass:[HQMCustomAnnotation class]]) {
HQMCustomAnnotation *cusAnnotation = (HQMCustomAnnotation *)annotation;
static NSString *cusAnnotationID = @"HQMCustomAnnotation";
HQMCustomAnnotationView *cusAnnotationView = (HQMCustomAnnotationView*)[mapView dequeueReusableAnnotationViewWithIdentifier:cusAnnotationID];
if (!cusAnnotationView) {
cusAnnotationView = [[HQMCustomAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:cusAnnotationID];
}
cusAnnotationView.annotation = cusAnnotation;
// cusAnnotationView.tag = i++;
return cusAnnotationView;
}
return nil;
}
2.4.2)根據點選類目一類目二的實現.
-(void)createBottomViewWithArray:(NSArray *)array
{
UIScrollView *bottomScrollView = [self.view viewWithTag:101];
for (UIView *subView in bottomScrollView.subviews) {
[subView removeFromSuperview];
}
bottomScrollView.contentSize = CGSizeMake(array.count * (kScreenWidth-30)/6.f, 0);
UIButton *_last1Btn;
NSInteger i = 0;
for (NSString *title in array) {
UIButton *btn = [UIButton buttonWithType:UIButtonTypeCustom];
btn.frame = CGRectMake(_last1Btn ? _last1Btn.right : 0, 0, (kScreenWidth-30)/6.f, 30);
[bottomScrollView addSubview:btn];
// [btn mas_makeConstraints:^(MASConstraintMaker *make) {
// make.left.equalTo(_lastBtn ? _lastBtn.mas_right : @0);
// make.top.bottom.equalTo(topScrollView);
// make.width.equalTo(@((kScreenWidth-30)/4.f));
// }];
btn.backgroundColor = kAppClearColor;
[btn setTitle:title forState:UIControlStateNormal];
// [topScrollView addSubview:btn];
btn.titleLabel.font = [UIFont boldSystemFontOfSize:12];
// [btn setTitleColor:[UIColor colorWithRed:0.3 green:0.3 blue:0.3 alpha:1] forState:UIControlStateNormal];
[btn setTitleColor:kAppBlackColor forState:UIControlStateNormal];
[btn addTarget:self action:@selector(btnAction1:) forControlEvents:UIControlEventTouchUpInside];
_last1Btn = btn;
i++;
btn.tag = 40+i;
if (btn.tag == 41) {
[btn setTitleColor:kAppGoodColor forState:UIControlStateNormal];
self.selectButton = btn;
}
}
}
2.5).點選類目一以及類目二的item
-(void)btnAction:(UIButton *)tb
{
[_DataArray2 removeAllObjects];
[_DataArray2Id removeAllObjects];
for (NSDictionary *dic in _TwoDataArray[tb.tag-11]) {
if (NotNilAndNull(dic[@"name"])) {
[_DataArray2 addObject:dic[@"name"]];
}
if (NotNilAndNull(dic[@"id"])) {
[_DataArray2Id addObject:dic[@"id"]];
}
}
[self createBottomViewWithArray:_DataArray2];
}
.//點選類目二item
-(void)btnAction1:(UIButton *)tb
{
// NSLog(@"按鈕%ld",tb.tag);
if(self.selectButton == tb) {
//上次點選過的按鈕，不做處理
} else{
//本次點選的按鈕設為紅色
[tb setTitleColor:kAppGoodColor forState:UIControlStateNormal];
//將上次點選過的按鈕設為黑色
[self.selectButton setTitleColor:kAppBlackColor forState:UIControlStateNormal];
}
self.selectButton = tb;
[self.mapView removeOverlays:self.mapView.overlays];
[self.mapView removeAnnotations:self.mapView.annotations];
//跟之前的生成標註一樣 移除資料來源 再次重新請求此類目下的使用者資訊
}
2.6).最後就是點選標註進入資訊 根據標註的位置和使用者的位置進行判斷
- (void)mapView:(MAMapView *)mapView didSelectAnnotationView:(MAAnnotationView *)view
{
// clickLocation 位置資訊
CLLocationCoordinate2D clickLocation = view.annotation.coordinate;
for (int i = 0; i < _dataArray.count; ++i)
{
ThirdMcModel *Model = _dataArray[i];
// NSLog(@"我你那麼 %f %f",[Model.UserX doubleValue],[Model.UserY doubleValue]);
if ([Model.UserX doubleValue] == clickLocation.latitude && [Model.UserY doubleValue] == clickLocation.longitude){
PersonalDataVC *person = [[PersonalDataVC alloc]init];
[self.navigationController pushViewController:person animated:YES];
}
}
}
2.7).最後上兩張做好的效果圖吧 上面的demo夠用了
