pagecontrol indicator custom image instead of Default

How can i change the color of pagination dots of UIPageControl?

In this link the sample code is given.But it shows 3 errors for me...

1'st ERROR:

Line:CGRect currentBounds = self.bounds;

Error:requst for member 'bounds' in something not a structure or union

Method:-(void)drawRect:

2nd Err: same error with same line in touchesBegan method.

3rd Err:@protocol PageControlDelegate

@optional

• (void)pageControlPageDidChange:(PageControl *)pageControl;

@end

Error:Expecte开发者_JS百科d ')' before 'PageControl' .These are the three errors occurs for me...Please help me out to solve this..

I want to change the pagecontrol indicator(dot) color...

Thanks & Regards, Renuga

first error is probably due to the fact that self does not refer to a view (a view controller maybe)

Second error is because PageControl is not yet defined by the time the parser come to your protocol definition.

Typical Class with delegate

@protocol MyProtocol;

@interface myClassWithDelegate
{
  id<MyProtocol> _delagate;
}

@end

@protocol MyProtocol
  -(void)MyClass:(MyClassWithDelegate*)c says(NSString*)message;
@end

I'm the one who wrote the sample code you are using.

I see that VdesmedT has already helped you on the syntax issues you were having. So +1 for that!

As for customizing the dots: The class as provided does not support custom images for the dots. It just draws circles using Core Graphics. The color of the circles is configured using the properties dotColorCurrentPage and dotColorOtherPage.

The default colors are grey dots with a black dot for the current page (because that is what I needed when I wrote it).

Let's say you want a red dot instead of a black dot for the current page and green dots for the other pages. When you create your PageControl instance you simply assign the properties like this:

pageControl.dotColorCurrentPage = [UIColor redColor];
pageControl.dotColorOtherPage = [UIColor greenColor];

... assuming your instance variable is called pageControl. Or use any of the other convenience/initialization methods for creating a UIColor that you like.

Hope this helps.
