UIPageControll

设置pageCon的显示风格:

1. 颜色

1 page.pageIndicatorTintColor = [UIColor redColor];
2 page.currentPageIndicatorTintColor = [UIColor greenColor];

2. 平铺图片

1 page.currentPageIndicatorTintColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"dot_selected"]];
2 page.pageIndicatorTintColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"dot_normal"]];

3. 修改属性

1 [page setValue:[UIImage imageNamed:@"compose_keyboard_dot_normal"] forKeyPath:@"pageImage"];
2 [page setValue:[UIImage imageNamed:@"compose_keyboard_dot_selected"] forKeyPath:@"currentPageImage"];
