方法一：重写setCurrentPage方法即可:
- (void) setCurrentPage:(NSInteger)page {
[super setCurrentPage:page];
for (NSUInteger subviewIndex = 0; subviewIndex < [self.subviews count]; subviewIndex++) {
UIImageView* subview = [self.subviews objectAtIndex:subviewIndex];
CGSize size;
size.height = 12;
size.width = 12;
[subview setFrame:CGRectMake(subview.frame.origin.x, subview.frame.origin.y,
size.width,size.height)];
if (subviewIndex == page) [subview setImage:[UIImage imageNamed:@"BluePoint.png"]];
else [subview setImage:[UIImage imageNamed:@"BlackPoint.png"]];
}
}
