iOS下拉刷新：BMYCircularProgressPullToRefresh

BMYCircularProgressPullToRefresh 是下拉刷新，带有圆形进程视图，类似 Beamly iOS 应用。

此版本的下拉刷新特性可以再 UITableViews 和 UICollection 上使用，灵感来源于 Sam Vermette's SVPlullToRefresh。

简单用法:

• 复制在BMYCircularProgressPullToRefresh文件夹中的所有类至你的项目中。
• import BMYCircularProgressPullToRefresh.h in your (view controller) class
• add the pull to refresh feature as so (you probably want to do to in the viewDidLoad method):

UIImage *logoImage = [UIImage imageNamed:@"bicon.png"];  UIImage *backCircleImage = [UIImage imageNamed:@"light_circle.png"];  UIImage *frontCircleImage = [UIImage imageNamed:@"dark_circle.png"];    BMYCircularProgressView *progressView = [[BMYCircularProgressView alloc] initWithFrame:CGRectMake(0, 0, 25, 25)                                                                                    logo:logoImage                                                                         backCircleImage:backCircleImage                                                                        frontCircleImage:frontCircleImage];    [self.scrollView setPullToRefreshWithHeight:60.0f actionHandler:^(BMYPullToRefreshView *pullToRefreshView){      // reload logic, call the following line when work is done       [pullToRefreshView stopAnimating];  }];    [self.scrollView.pullToRefreshView setPreserveContentInset:YES];  [self.scrollView.pullToRefreshView setProgressView:progressView];    - (void)dealloc {      [self.scrollView tearDownPullToRefresh];  }
