1.修改大小，创建一个类，继承UIPageControl，重写setCurrentPage方法，可设置圆点大小
- (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 = 10;
size.width = 10;
[subview setFrame:CGRectMake(subview.frame.origin.x, subview.frame.origin.y,
size.width,size.height)];
}
}
2.如果只改变当前选中的点的大小，前面加个判断就可以了：
- (void) setCurrentPage:(NSInteger)page {
[super setCurrentPage:page];
for (NSUInteger subviewIndex = 0; subviewIndex < [self.subviews count]; subviewIndex++) {
if (subviewIndex == page)
{
UIImageView* subview = [self.subviews objectAtIndex:subviewIndex];
CGSize size;
size.height = 10;
size.width = 10;
[subview setFrame:CGRectMake(subview.frame.origin.x, subview.frame.origin.y,
size.width,size.height)];
}
}
}
3.将点显示成图片的方法
[pageCon setValue:[UIImage imageNamed:@"BluePoint.png"] forKeyPath:@"_currentPageImage"];
[pageCon setValue:[UIImage imageNamed:@"black"] forKeyPath:@"_pageImage"];
4.设置点的颜色的方法
pageCon.pageIndicatorTintColor = [UIColor blackColor];
pageCon.currentPageIndicatorTintColor = [UIColor redColor];
