1.百度地图开发中添加标注[_mapView addAnnotations:annotations]与[_mapView addAnnotation: annotation] 的不同

/** 
*向地图窗口添加标注，需要实现BMKMapViewDelegate的-mapView:viewForAnnotation:函数来生成标注对应的View 
*@param annotation 要添加的标注
 */
- (void)addAnnotation:(id )annotation;
/** 
*向地图窗口添加一组标注，需要实现BMKMapViewDelegate的-mapView:viewForAnnotation:函数来生成标注对应的View *@param annotations 要添加的标注数组 
*/
- (void)addAnnotations:(NSArray *)annotations;addAnnotation是每次添加一个标注，之后在- (BMKAnnotationView *)mapView:(BMKMapView *)mapView viewForAnnotation:(id )annotation;
中paopaoView的显示内容是不同的，addAnnotation是添加一个标注数组，之后(BMKAnnotationView *)mapView:(BMKMapView *)mapView viewForAnnotation:(id )annotation;

paopaoview显示的内容是数组最后一个元素的内容。

2.百度地图api自定义paopaoView，push到一个新的界面，返回之后再点击paopaoView不在有反应，解决办法：

下面这两个方法(void)mapView:(BMKMapView *)mapView didAddAnnotationViews:(NSArray *)views;
和

• (void)mapView:(BMKMapView*)mapView annotationViewForBubble:(BMKAnnotationView *)view;
  不要使用， 在自定义的泡泡view里最上面覆盖一个透明的按钮，之后在- (BMKAnnotationView )mapView:(BMKMapView)mapView viewForAnnotation:(id )annotation这个方法里初始化自定义的View，之后为view里的按钮添加一个监听事件，为button设置tag值，之后在点击方法里

//pragma mark paopao按钮点击
-(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; //计算所选坐标和当前位置之间的距离 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]; 
} 
}
}

就可以跳转到对应的界面了。

3.设置状态栏为白色的方法

//pragma mark 设置状态栏的为白色
-(void)navigationController:(UINavigationController *)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated{
 [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];
}

//pragma mark 设置状态栏的为白色
-(void)navigationController:(UINavigationController *)navigationController didShowViewController:(UIViewController *)viewController animated:(BOOL)animated{
 [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];
}

---

4.自定义导航栏侧滑返回失效

-(void)viewDidLoad { 
[super viewDidLoad];
__weak typeof (self) weakSelf = self; 
if ([self respondsToSelector:@selector(interactivePopGestureRecognizer)]) { 
self.interactivePopGestureRecognizer.delegate = weakSelf; 
}
}

---

iOS7之后可以添加一个手势,要设置代理UIGestureRecognizerDelegate

//支持右滑手势 
if ([[[UIDevice currentDevice] systemVersion] floatValue]>=7) { 
self.navigationController.interactivePopGestureRecognizer.delegate=self;
 }

5.BMKMapPoint * temppoints = new BMKMapPoint[planPointCounts]; ‘delete []temppoints;’报错

解决办法:new和delete是c++里的语法。要么把源文件后缀名改成.mm要么用c的malloc。这其实是objc开发的问题了，不算百度SDK的问题。
