[BMKGradient generateColorMap:resultColorMap:]: unrecognized selector sent to...
: unrecognized selector sent to instance 0x7fae64f32260如题，这么恶心的一个问题，找了好久，百度上也找不到相关答案，最后还是问Google问出来的！
解决方案是在Build Settings--Linking--中添加一个“-ObjC”,即可搞定！
附加百度添加热力图的demo方法：
BMKHeatMap* heatMap = [ init];
NSMutableArray* data = ;
int num = 1000;
for(int i = 0; i<num; i++)
{
//创建BMKHeatMapNode
BMKHeatMapNode* heapmapnode_test = [ init];
//此处示例为随机生成的坐标点序列，开发者使用自有数据即可
CLLocationCoordinate2D coor;
float random = (arc4random()%1000)*0.001;
float random2 = (arc4random()%1000)*0.003;
float random3 = (arc4random()%1000)*0.015;
float random4 = (arc4random()%1000)*0.016;
if(i%2==0){
coor.latitude = 39.915+random;
coor.longitude = 116.403+random2;
}else{
coor.latitude = 39.915-random3;
coor.longitude = 116.403-random4;
}
heapmapnode_test.pt = coor;
//随机生成点强度
heapmapnode_test.intensity = arc4random()*900;
//添加BMKHeatMapNode到数组
;
}
//将点数据赋值到热力图数据类
heatMap.mData = data;
//调用mapView中的方法根据热力图数据添加热力图
;
