那就自定义UIPageControl，现成的代码，送给你，记得继承UIPageControl，试过了，完美符合你的要求
#import "BQCustomPageControl.h"
#define circleWidth 10.0
#define circlePadding 12.5
@implementation BQCustomPageControl
- (void)layoutSubviews{
[super layoutSubviews];
//计算圆点间距
CGFloat marginX = circleWidth + circlePadding;
//计算整个pageControll的宽度
CGFloat newWidth = (self.subviews.count-1)*marginX + circleWidth;
//设置新frame
self.frame = CGRectMake(self.frame.origin.x, self.frame.origin.y, newWidth, self.frame.size.height);
//设置居中
CGPoint center = self.center;
center.x = self.superview.center.x;
self.center = center;
//遍历subview,设置圆点frame
for (int i=0; i<[self.subviews count]; i++) {
UIImageView *dot = [self.subviews objectAtIndex:i];
dot.layer.cornerRadius = circleWidth*0.5;
if (i == self.currentPage) {
[dot setFrame:CGRectMake(i * marginX, dot.frame.origin.y, circleWidth, circleWidth)];
}else {
[dot setFrame:CGRectMake(i * marginX, dot.frame.origin.y, circleWidth, circleWidth)];
}
}
