배경이미지 주기 삽질

1.  배경색 주기
    CGContextRef ctx=UIGraphicsGetCurrentContext();
    CGContextSetRGBFillColor(ctx, 05.f, 0.5f, 0.5f, 0.9f);
    CGContextFillRect(ctx, CGRectMake(5, headHeight-28,self.frame.size.width,30 ));

 2. 이미지 백그라운드 패턴식으로 주기
 UIView *mainTitle = [[UIView alloc] initWithFrame:CGRectMake(5, headHeight-28, 320, 30    )];
 mainTitle.backgroundColor = [[UIColor alloc] initWithPatternImage:[UIImage imageNamed:@"car_bar.png"]];
 
3. 이미지 주기
    UIImageView *mainTitle = [[[UIImageView alloc] initWithImage:[UIImage imageNamed:@"car_bar.png"]] autorelease];
    mainTitle.frame = CGRectMake(5, headHeight-28, mainTitle.frame.size.width,mainTitle.frame.size.height);
    [self addSubview:mainTitle];


4. CGContextDrawImage 사용하기
    CGContextRef ctx=UIGraphicsGetCurrentContext();
    UIImage *c = [UIImage imageNamed:@"car_bar.png"];
    CGImageRef cRef = CGImageRetain(c.CGImage);   
    CGContextDrawImage(ctx, CGRectMake(5, headHeight-28,c.size.width, c.size.height+1), cRef);
    [c drawInRect:CGRectMake(5, headHeight-28,c.size.width, c.size.height+1)];
