關(guān)于導(dǎo)入百度地圖SDK出現(xiàn)的問(wèn)題(二)
1.百度地圖開發(fā)中添加標(biāo)注[_mapView addAnnotations:annotations]與[_mapView addAnnotation: annotation] 的不同
/**
*向地圖窗口添加標(biāo)注，需要實(shí)現(xiàn)BMKMapViewDelegate的-mapView:viewForAnnotation:函數(shù)來(lái)生成標(biāo)注對(duì)應(yīng)的View
*@param annotation 要添加的標(biāo)注
*/
- (void)addAnnotation:(id <BMKAnnotation>)annotation;
/**
*向地圖窗口添加一組標(biāo)注，需要實(shí)現(xiàn)BMKMapViewDelegate的-mapView:viewForAnnotation:函數(shù)來(lái)生成標(biāo)注對(duì)應(yīng)的View *@param annotations 要添加的標(biāo)注數(shù)組
*/
- (void)addAnnotations:(NSArray *)annotations;addAnnotation是每次添加一個(gè)標(biāo)注，之后在- (BMKAnnotationView *)mapView:(BMKMapView *)mapView viewForAnnotation:(id <BMKAnnotation>)annotation;
中paopaoView的顯示內(nèi)容是不同的，addAnnotation是添加一個(gè)標(biāo)注數(shù)組，之后(BMKAnnotationView *)mapView:(BMKMapView *)mapView viewForAnnotation:(id <BMKAnnotation>)annotation;
paopaoview顯示的內(nèi)容是數(shù)組最后一個(gè)元素的內(nèi)容。
2.百度地圖api自定義paopaoView，push到一個(gè)新的界面，返回之后再點(diǎn)擊paopaoView不在有反應(yīng)，解決辦法：
下面這兩個(gè)方法(void)mapView:(BMKMapView *)mapView didAddAnnotationViews:(NSArray *)views;
和
- (void)mapView:(BMKMapView*)mapView annotationViewForBubble:(BMKAnnotationView *)view;
不要使用， 在自定義的泡泡view里最上面覆蓋一個(gè)透明的按鈕，之后在- (BMKAnnotationView )mapView:(BMKMapView)mapView viewForAnnotation:(id )annotation這個(gè)方法里初始化自定義的View，之后為view里的按鈕添加一個(gè)監(jiān)聽事件，為button設(shè)置tag值，之后在點(diǎn)擊方法里
//pragma mark paopao按鈕點(diǎn)擊
-(void)btnClick:(UIButton *)button{
for (int i = 0; i < self.annotations.count; i++) {
HXMenDList *menDList = self.annotations[i];
if (button.tag == [menDList.ID integerValue]) {
HXDetailsController *detailsV = [[HXDetailsController alloc] init];
detailsV.menDList = menDList; //計(jì)算所選坐標(biāo)和當(dāng)前位置之間的距離 CLLocationCoordinate2D
currentAnno = CLLocationCoordinate2DMake([menDList.weid doubleValue], [menDList.jind doubleValue]); BMKMapPoint mp1 =
BMKMapPointForCoordinate(currentAnno);
BMKMapPoint mp2 = BMKMapPointForCoordinate(self.userLocation.location.coordinate);
CLLocationDistance distance = BMKMetersBetweenMapPoints(mp1, mp2);
distance = [Tools formatDistance:distance];
menDList.distance = distance;
NSLog(@"detailsV.menDList.dianm==%@",detailsV.menDList.dianm);
[self.navigationController pushViewController:detailsV animated:YES];
}
}
}
就可以跳轉(zhuǎn)到對(duì)應(yīng)的界面了。
3.設(shè)置狀態(tài)欄為白色的方法
//pragma mark 設(shè)置狀態(tài)欄的為白色
-(void)navigationController:(UINavigationController *)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated{
[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];
}
//pragma mark 設(shè)置狀態(tài)欄的為白色
-(void)navigationController:(UINavigationController *)navigationController didShowViewController:(UIViewController *)viewController animated:(BOOL)animated{
[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];
}
4.自定義導(dǎo)航欄側(cè)滑返回失效
-(void)viewDidLoad {
[super viewDidLoad];
__weak typeof (self) weakSelf = self;
if ([self respondsToSelector:@selector(interactivePopGestureRecognizer)]) {
self.interactivePopGestureRecognizer.delegate = weakSelf;
}
}
iOS7之后可以添加一個(gè)手勢(shì),要設(shè)置代理UIGestureRecognizerDelegate
//支持右滑手勢(shì)
if ([[[UIDevice currentDevice] systemVersion] floatValue]>=7) {
self.navigationController.interactivePopGestureRecognizer.delegate=self;
}
5.BMKMapPoint * temppoints = new BMKMapPoint[planPointCounts]; ‘delete []temppoints;’報(bào)錯(cuò)
解決辦法:new和delete是c++里的語(yǔ)法。要么把源文件后綴名改成.mm要么用c的malloc。這其實(shí)是objc開發(fā)的問(wèn)題了，不算百度SDK的問(wèn)題。
