mySearchBar.backgroundColor = RGBACOLOR(249,249,249,1); mySearchBar.backgroundImage = [self imageWithColor:[UIColor clearColor] size:mySearchBar.bounds.size]; //取消searchbar背景色- (UIImage *)imageWithColor:(UIColor *)color size:(CGSize)size{ CGRect rect = CGRectMake(0, 0, size.width, size.height); UIGraphicsBeginImageContext(rect.size); CGContextRef context = UIGraphicsGetCurrentContext(); CGContextSetFillColorWithColor(context, [color CGColor]); CGContextFillRect(context, rect); UIImage *image = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); return image;} |
