1.获取屏幕大小：

CGSize dispViewSize = [[UIScreen mainScreen] bounds].size;

2。一个小的子View显示，disable 背景的大View

在背景的大View上添加一个半透明的button，在显示子View

3.添加Navigate：

UIBarButtonItem *leftButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemCancel target:self action:@selector(gotoPresentationView:)];
    self.navigationItem.leftBarButtonItem = leftButton;
    
    UIBarButtonItem *rightButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:@selector(openCloudView:)];
    self.navigationItem.rightBarButtonItem = rightButton;

4.定义view的推出方向为从右到左：

-(void)navigationLeftToRightAnimation
{
    CATransition *transition = [CATransition animation];
    transition.duration = 0.5;
    transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
    transition.type = kCATransitionMoveIn;
    transition.subtype = kCATransitionFromBottom;
    transition.delegate = self;
    [self.navigationController.view.layer addAnimation:transition forKey:nil];
    
    self.navigationController.navigationBarHidden = NO;
    [self.navigationController pushViewController:documentViewcontroller animated:YES];
    
}

5.在任意文件中获取当前工程的delegate：

KWAppDelegate* pApp = (KWAppDelegate*)[UIApplication sharedApplication].delegate;

6.隐藏UITableView没有的cell的横线：

-(void)setExtraCellLineHidden
{
    UIView *view = [[UIView alloc] init];
    view.backgroundColor = [UIColor clearColor];
    [self.mTableView setTableFooterView:view];
    [view release];
}
