CGImageを使う方法

-(UIImage*)getCUIImage:(UIImage*)img{
    return [UIImage imageWithCGImage:[img CGImage]];
}

CGImageを使わない方法

-(UIImage*)getCopyUIImage:(UIImage*)imageToCopy{
    UIGraphicsBeginImageContext(imageToCopy.size);
    [imageToCopy drawInRect:CGRectMake(0, 0, imageToCopy.size.width, imageToCopy.size.height)];
    UIImage *copiedImage =UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();  
    return copiedImage;
}

UIImageを2枚重ねた状態をUIImageにする

-(UIImage*)getWImage:(UIImage*)bottomImage frontImage:(UIImage*)frontImage{
    int width = bottomImage.size.width;
    int height = bottomImage.size.height;
    
    CGSize newSize = CGSizeMake(width, height);
    UIGraphicsBeginImageContextWithOptions(newSize, NO, 1.0);
    [bottomImage drawInRect:CGRectMake(0,0,newSize.width,newSize.height)];
    [frontImage drawInRect:CGRectMake(0,0,newSize.width,newSize.height) blendMode:kCGBlendModeNormal alpha:1.0];
    
    UIImage *newImage = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();
    
    return newImage;
}

EGODatabaseはスレッドセーフなSQLiteのラッパーです。

-(EGODatabase*)getDB{
    EGODatabase* database = [EGODatabase databaseWithPath:[NSHomeDirectory() stringByAppendingPathComponent:@"Documents/database.db"]];
    return database;
}
EGODatabase* database=[self getDB];
NSString*sql=[NSString stringWithFormat:@"create table if not exists '%@' (id int,gno int,type int,filename varchar);",tableName];
EGODatabaseResult*result= [database executeQuery:sql];
if (result.errorCode) {//failed
        
}else{//success
        
}
