【问题描述】：

嗨，我想增加 ios 上 UIPAgeControl 的大小...在谷歌上我找到了这个http://www.onidev.com/2009/12/02/customisable-uipagecontrol/

想知道有没有其他方法......？

【参考方案1】：

我使用了这个代码：

来源：http://apptech.next-munich.com/2010/04/customizing-uipagecontrols-looks.html

// header
@interface StyledPageControl : UIPageControl  

@end

// implementation
@implementation StyledPageControl

- (void) setCurrentPage:(NSInteger)page 
 [super setCurrentPage:page];

 NSString* imgActive = [[NSBundle mainBundle] pathForResource:IMG_PAGE_ACTIVE ofType:nil];
 NSString* imgInactive = [[NSBundle mainBundle] pathForResource:IMG_PAGE_INACTIVE ofType:nil];
 for (NSUInteger subviewIndex = 0; subviewIndex < [self.subviews count]; subviewIndex++) 
  UIImageView* subview = [self.subviews objectAtIndex:subviewIndex];
  if (subviewIndex == page) [subview setImage:[UIImage imageWithContentsOfFile:imgActive]];
  else [subview setImage:[UIImage imageWithContentsOfFile:imgInactive]];
 


- (void) setNumberOfPages:(NSInteger)pages 
 [super setNumberOfPages:pages];

 NSString* img = [[NSBundle mainBundle] pathForResource:IMG_PAGE_INACTIVE ofType:nil];
 for (NSUInteger subviewIndex = 0; subviewIndex < [self.subviews count]; subviewIndex++) 
  UIImageView* subview = [self.subviews objectAtIndex:subviewIndex];
  [subview setImage:[UIImage imageWithContentsOfFile:img]];
