-(UIImage*)createImageWithColor:(UIColor*)color{
CGRect rect=CGRectMake(0.0f,0.0f,1.0f,1.0f);UIGraphicsBeginImageContext(rect.size);
CGContextRef context = UIGraphicsGetCurrentContext();
CGContextSetFillColorWithColor(context,[color CGColor]);
CGContextFillRect(context,rect);UIImage *theImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();returntheImage;
}
调用：
[self createImageWithColor:[UIColor whiteColor]]
