我是最近接触的百度读图开发，百度地图的相关sdk api开发写的很简单，有很多都是写的不是很详细，但是如果我们想深究就会遇到很多问题，有许多我们想获得都东西往往都没法获得。直接步入正题吧，遇到问题如下：

一：我新申请的key，为啥没有用？地图没法加载，这个很有可能是你申请的key，有了，但是没有认证开发者，这就导致你的key没有用，地图没有加载出来，这个问题困扰了我很久才发现。

二：第一次使用百度地图的时候，必要的就是看Demo怎么使用这些方法。在使用官方Demo的时候地图真机测试就会出错，这个错误我大概记得，一个别忘申请新的key，二，别忘了选择证书，往往这个会导致错误

CodeSign error: code signing is required for product type 'Application' in SDK 'iOS 9.2'

这个就是证书没有选择的错误

三：按照官方文档创建地图后以及写了相关方法，这里我就不多说了，值得注意的是如果我们如果想获取当前的经纬度的话就得引入定位服务，通过

[self.myLocationService startUserLocationService];

设置BMKLocationService

的代理人通过代理方法开启定位服务后就会执行updatelocation方法获取当前的经纬度，设置为地图中心点。值得注意的事，要在这停止定位服务，要不然的你的如何移动地图，地图的中心点会在隔几秒会回到原处。这是我个人的方法，不对的话，给我提出来。同事显示定位的图层

 self.myLocationService = [[BMKLocationService alloc]init];[self.myLocationService startUserLocationService];//开始定位服务
//    self.mapView.showsUserLocation = NO;
//    self.mapView.userTrackingMode = BMKUserTrackingModeFollow;
//    self.mapView.showsUserLocation = YES;self.myMapView.showsUserLocation = NO;self.myLocationService.delegate = self;self.myMapView.userTrackingMode = BMKUserTrackingModeFollow;//设置定位的状态self.myMapView.showsUserLocation = YES;//显示定位图层

四：自定义定位图层的图标，也许你们应该使用过百度的导航服务，仔细的人就会发现，地位图标是跟随样式，如果要因为这个图标旋转，就引入导航的SDK那就有点大材小用，导致APP的包过大，其实在我们可以重写这个

BMKLocationViewDisplayParam

这个类对象，根据将其中的imagename改成你的那个替换图片就行

 BMKLocationViewDisplayParam *param = [[BMKLocationViewDisplayParam alloc] init];param.isRotateAngleValid = YES;param.isAccuracyCircleShow = YES;param.locationViewImgName = @"icon_center_point1";param.locationViewOffsetX = 0;param.locationViewOffsetY = 0;[self.myMapView updateLocationViewWithParam:param];

icon_center_poin这个是boudle资源中的定位图层的那个图片名称，可以换成你想要的图片名称就行

五：自定义大投标，这个就需要你自己写一个类继承

BMKAnnotationView

这个类就行，然后就在其中创建你想要的一些信息，也可以创建paopaoView这个就是你点击这个大头针弹出的时候，你就可以自定义视图，想展示什么内容就展示什么内容。这个是我自定义大投标的的那个类。m文件中主要的方法

@interface LL_MapViewAnnotationView()
@property(nonatomic,strong)UIImageView *myHeadImageView;
@end
@implementation LL_MapViewAnnotationView
@synthesize headViewName;
-(id)initWithAnnotation:(id<BMKAnnotation>)annotation reuseIdentifier:(NSString *)reuseIdentifier
{self = [super initWithAnnotation:annotation reuseIdentifier:reuseIdentifier];if (self) {[self setBounds:CGRectMake(0, 0, 50, 55)];UIButton *button = [[UIButton alloc]initWithFrame:CGRectMake(0, 0, 50, 55)];[button setBackgroundImage:[UIImage imageNamed:@"btn_确定"] forState:UIControlStateNormal];[self addSubview:button];self.myHeadImageView = [[UIImageView alloc]initWithFrame:CGRectMake(2, 5, 45, 45)];self.myHeadImageView.clipsToBounds = YES;self.myHeadImageView.layer.cornerRadius = 22.5;[button addSubview:self.myHeadImageView];button.userInteractionEnabled = NO;BMKActionPaopaoView *paopaoView = [[BMKActionPaopaoView alloc]initWithCustomView:[self createPaopaoViewWithModel]];self.paopaoView = paopaoView;}return self;
}

{UIView *view = [[UIView alloc]initWithFrame:CGRectMake(0, 0, 250,143)];UIView *lineView = [[UIView alloc]initWithFrame:CGRectMake(0, 0, 1, 143)];[view addSubview:lineView];UIView *allView = [[UIView alloc]initWithFrame:CGRectMake(0, 0, 250, 143)];[lineView addSubview:allView];
//    view.alpha = 0.4;allView.backgroundColor = [[Unity getColor:@"#000000"] colorWithAlphaComponent:0.4];//头像UIImageView *imageView = [[UIImageView alloc]initWithFrame:CGRectMake(15, 8, 100, 100)];[imageView setImage:[UIImage imageNamed:@"img1"]];imageView.clipsToBounds = YES;imageView.layer.cornerRadius = 50;[view addSubview:imageView];//删除buttonUIButton *deleateBut =[[UIButton alloc]initWithFrame:CGRectMake(view.frame.size.width -5-20, 8, 20, 20)];[deleateBut setBackgroundImage:[UIImage imageNamed:@"ic_btn_Deleate"] forState:UIControlStateNormal];deleateBut.tag = 1001;[view addSubview:deleateBut];[deleateBut addTarget:self action:@selector(buttonAction:) forControlEvents:UIControlEventTouchDown];//距离LableUILabel *distence = [[UILabel alloc]initWithFrame:CGRectMake(CGRectGetMaxX(imageView.frame)+20, 14, 101, 20)];[view addSubview:distence];NSMutableAttributedString *string = [[NSMutableAttributedString alloc]init];//添加图片的NSTextAttachment *attach = [[NSTextAttachment alloc]init];attach.image = [UIImage imageNamed:@"ic_find_Distence"];attach.bounds =CGRectMake(0, -5, 30, 20);NSAttributedString *attachString = [NSAttributedString attributedStringWithAttachment:attach];[string appendAttributedString:attachString];NSString *tempStr = [NSString stringWithFormat:@"  距离"];NSMutableAttributedString *textStr = [[NSMutableAttributedString alloc]initWithString:tempStr];[textStr addAttribute:NSForegroundColorAttributeName value:[Unity getColor:@"#FFFFFF"] range:NSMakeRange(0, tempStr.length)];[textStr addAttribute:NSFontAttributeName value:[UIFont systemFontOfSize:13] range:NSMakeRange(0, tempStr.length)];[string appendAttributedString:textStr];distence.attributedText = string;//距离数量LableUILabel *distenceNum = [[UILabel alloc]initWithFrame:CGRectMake(CGRectGetMinX(distence.frame), CGRectGetMaxY(distence.frame), view.frame.size.width-CGRectGetMinX(distence.frame)-40, 30)];NSString *distenceNumText = [NSString stringWithFormat:@"153  米"];NSMutableAttributedString *distenceString = [[NSMutableAttributedString alloc]initWithString:distenceNumText];[distenceString addAttribute:NSForegroundColorAttributeName value:[Unity getColor:@"#FFFFFF"] range:NSMakeRange(0, 3)];[distenceString addAttribute:NSFontAttributeName value:[UIFont systemFontOfSize:19] range:NSMakeRange(0, 3)];[distenceString addAttribute:NSForegroundColorAttributeName value:[Unity getColor:@"#FDB100"] range:NSMakeRange(5, 1)];[distenceString addAttribute:NSFontAttributeName value:[UIFont systemFontOfSize:11] range:NSMakeRange(5, 1)];distenceNum.attributedText = distenceString;distenceNum.textAlignment = NSTextAlignmentCenter;[view addSubview:distenceNum];UIView *downLoadView = [[UIView alloc]initWithFrame:CGRectMake(0, 90, 250, 53)];downLoadView.backgroundColor = [[Unity getColor:@"#4D4D4D"] colorWithAlphaComponent:0.5];[view addSubview:downLoadView];UIView *sexBackView = [[UIView alloc]initWithFrame:CGRectMake(0, 0, 35, 53)];[sexBackView setBackgroundColor:[Unity getColor:@"#FFB300"]];[downLoadView addSubview:sexBackView];UIImageView *sexImageView = [[UIImageView alloc]initWithFrame:CGRectMake(5, 14, 25, 25)];[sexBackView addSubview:sexImageView];sexImageView.clipsToBounds = YES;sexImageView.layer.cornerRadius = 12.5;[sexBackView addSubview:sexImageView];[sexImageView setImage:[UIImage imageNamed:@"ic_男"]];//姓名lableUILabel *nameLable = [[UILabel alloc]initWithFrame:CGRectMake(CGRectGetMaxX(sexBackView.frame)+12, 8, 120, 25)];nameLable.textColor = [Unity getColor:@"#FFFFFF"];nameLable.font = [UIFont systemFontOfSize:18];nameLable.text = @"张三";[downLoadView addSubview:nameLable];//个性签名UILabel *mySignText = [[UILabel alloc]initWithFrame:CGRectMake(CGRectGetMinX(nameLable.frame), CGRectGetMaxY(nameLable.frame), 120, 20)];mySignText.textColor = [Unity getColor:@"#FFFFFF"];mySignText.font = [UIFont systemFontOfSize:12];mySignText.text = @"个性签名";[downLoadView addSubview:mySignText];//查看buttonUIButton *lookButton = [[UIButton alloc]initWithFrame:CGRectMake(downLoadView.frame.size.width-10-80, 20, 80, 30)];[lookButton setImage:[UIImage imageNamed:@"ic_look_detail"] forState:UIControlStateNormal];[lookButton setTitle:@"查看" forState:UIControlStateNormal];[lookButton setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];lookButton.tag = 1002;[lookButton addTarget:self action:@selector(buttonAction:) forControlEvents:UIControlEventTouchDown];[downLoadView addSubview:lookButton];return view;
}

六：在创建大头针的时候也很简单和官方的说法一样，值得注意的就是添加其中的一些方法就行

- (BMKAnnotationView *)mapView:(BMKMapView *)mapView viewForAnnotation:(id <BMKAnnotation>)annotation
{NSString *AnnotationViewID = @"AnimatedAnnotation";LL_MapViewAnnotationView *annotationView = nil;if (annotationView == nil) {annotationView = [[LL_MapViewAnnotationView alloc]initWithAnnotation:annotation reuseIdentifier:AnnotationViewID];[annotationView upHeadViewNameWithString:@"img1"];annotationView.myBlock = ^(NSInteger tag){switch (tag) {case 1001:{NSLog(@"删除按钮");}break;case 1002:{NSLog(@"查看按钮");}break;default:break;}};}return annotationView;}

这段代码是加大头针的方法，里面不要管别的，其他的不用想，想多了就很麻烦，我之前就是那样以为通过什么方法调用就行，其实这个跟tableView一样给个数据，设定高度，cell的数量，然后就是在代理方法中写返回的cell的样式就行

BMKPointAnnotation* annotation = [[BMKPointAnnotation alloc]init];CLLocationCoordinate2D coor;coor.latitude = 39.915;coor.longitude = 116.404;annotation.coordinate = coor;annotation.title = @"这里是北京";[self.myMapView addAnnotation:annotation];

其实还有别的问题，明天再说，今天有点累了，要睡觉了
