标签：动手做 alloc nil -- NSLog self 甚靠 mapView void
1：申请key,在appdelegate中加入相应的代码。比如。
appdelegate.h中：
#import <UIKit/UIKit.h>
#import <FMDB.h>
#import <BaiduMapAPI_Base/BMKBaseComponent.h>//引入base相关所有的头文件
#import <BaiduMapAPI_Map/BMKMapComponent.h>//引入地图功能所有的头文件
@interface AppDelegate : UIResponder <UIApplicationDelegate>
{
BMKMapManager *_mapManager;
}
@property (nonatomic,strong)NSMutableArray *contactsArray;
@property (strong,nonatomic) UIWindow *window;
@property (nonatomic,strong)FMDatabase * db;
@end
在appdelegate.m中增加对应的初始化：
//百度地图
_mapManager = [[BMKMapManageralloc]init];
// 如果要关注网络及授权验证事件，请设定 generalDelegate参数
BOOL ret = [_mapManagerstart:@"xxxxxxxxxxxxx" generalDelegate:nil];
if (!ret) {
NSLog(@"manager start failed!");
}
注：这个xxxxxxxx是自己当时申请的。
如果在appdelegate里面不增加的话，就会导致整个程序页面假死，程序不崩溃就是直接僵死在那儿，而且还会影响到整个手机的性能。
2：info.plist中需要增加两个字段（）
NSLocationWhenInUseUsageDescription
NSLocationAlwaysUsageDescription
字段需要增加，但是值的话可以为空。-----这两个字段如果不加的话，会出现百度地图总是自动定位到北京天安门的问题。--天安门上红旗飘~~~~~~
3：地图控制器的代码
.h代码
#import <UIKit/UIKit.h>
#import <BaiduMapAPI_Base/BMKBaseComponent.h>//引入base相关所有的头文件
#import <BaiduMapAPI_Map/BMKMapComponent.h>//引入地图功能所有的头文件
#import <BaiduMapAPI_Search/BMKSearchComponent.h>//引入检索功能所有的头文件
#import <BaiduMapAPI_Location/BMKLocationComponent.h>//引入定位功能所有的头文件
@interface LocationViewController : UIViewController{
BMKMapManager *_mapManager;
}
@property (nonatomic,copy) NSString * titleString;
@end
.m代码
//
// LocationViewController.m
// TeamTalk
//
#import "common.h"
#import "LocationViewController.h"
#import "LocationRecordViewController.h"
