// 文件存放目录

NSString *pngDir
= [NSHomeDirectory()stringByAppendingPathComponent:@"Documents"];

NSFileManager *fileMgr = [NSFileManagerdefaultManager];

NSString *FileDir = [NSStringstringWithFormat:@"%@/AnnexFiles",
pngDir];

NSError *err;

[fileMgr createDirectoryAtPath:FileDirwithIntermediateDirectories:YES attributes:nil error:&err];

NSString *FileFullPath = [FileDir stringByAppendingPathComponent:[DBTopicAnnexData Name]];

BOOL bRet = [fileMgrfileExistsAtPath:FileFullPath];

if (bRet) {

//

NSError *err;

[fileMgr removeItemAtPath:FileFullPath error:&err];

}

或者

// 清除本地配置数据

NSArray *paths
= NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);

NSString *documentsDirectory = [paths objectAtIndex:0];

NSFileManager *fileMgr = [NSFileManager defaultManager];

NSString *MapLayerDataPath = [documentsDirectory stringByAppendingPathComponent:@"DBMapLayerData.xml"];

BOOL bRet = [fileMgrfileExistsAtPath:MapLayerDataPath];

if (bRet) {

//

NSError *err;

[fileMgr removeItemAtPath:MapLayerDataPatherror:&err];

}
