环境：xcode5.1+ios7.1+openflow+ipad

说明：在view 添加openflow，xib是其他视图为自动布局；ipad横屏时 水平线未满屏；修改openflow的refreshCoverFlow方法如下：

//设置openflow的大小     AFOpenFlowView *coverFlowView = [[AFOpenFlowView alloc] initWithFrame:CGRectMake(0, 50, self.view.frame.size.width, self.view.frame.size.height-100)];              coverFlowView.translatesAutoresizingMaskIntoConstraints = NO;  //禁用自动布局     NSDictionary *viewsbg = NSDictionaryOfVariableBindings(self.view,coverFlowView);     [self.view addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"|-0-[coverFlowView]-0-|" options:0 metrics:0 views:viewsbg]];     //    [self.view addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"|-0-[bgImage]-0-|" options:0 metrics:0 views:viewsbg]];     [self.view addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"V:|-50-[coverFlowView]-50-|" options:0 metrics:0 views:viewsbg]];

  

ios openflow 自动布局及大小
