在寫項目時,要實現一個從下移上來的一個快顯功能表,並且背景變深的這麼一個效果,在此分享給大家。
主要說一下思路及一些核心代碼貼出來,要想下載源碼,

一個簡單,效果好,比較實用的菜單彈出效果的實現,:
實現方式:將self.view當前頁面縮小,在當前頁的上面添加一個菜單的view,即在self.view.superview添加。
[cpp] view plaincopy
- //顯示
- - (void) show:(UIView*)parent
- {
- parentView = parent;
-
- //先隱藏backView,table
- backView.alpha = 0;
- _table.alpha = 0;
-
- //移動table
- [_table setTransform:CGAffineTransformMakeTranslation(0, _table.frame.size.height)];
-
- //父視窗添加本view,---這個會調用viewDidLoad
- [parentView.superview addSubview:self.view];
-
- //添加動畫,添加到父視窗中,使之從下移動上
- [UIView animateWithDuration:0.3 animations:^{
- //父視窗縮小
- CGAffineTransform t = CGAffineTransformMakeScale(0.9, 0.9);
- [parentView setTransform:t];
-
- //顯示backview,table
- backView.alpha = 1;
- _table.alpha = 1;
-
- //移動table,CGAffineTransformIdentity還原原始座標
- [_table setTransform:CGAffineTransformIdentity];
-
- } completion:^(BOOL finished) {
-
- }];
-
-
- }
- //隱藏
- - (void) hide
- {
- //添加動畫,添加到父視窗中,使之從下移動上
- [UIView animateWithDuration:0.3 animations:^{
- //父視窗還原
- CGAffineTransform t = CGAffineTransformIdentity;
- [parentView setTransform:t];
-
- //顯示backview,table
- backView.alpha = 0;
- _table.alpha = 0;
-
- //移動table
- [_table setTransform:CGAffineTransformMakeTranslation(0, _table.frame.size.height)];
-
- } completion:^(BOOL finished) {
- [self.view removeFromSuperview];
- }];
- }
-
- - (void)viewDidLoad
- {
- [super viewDidLoad];
-
- self.view.backgroundColor = [UIColor clearColor];
-
- //背影黑罩
- backView = [[UIView alloc]initWithFrame:self.view.bounds];
- backView.backgroundColor = [UIColor colorWithRed:0 green:0 blue:0 alpha:0.3];
- [self.view addSubview:backView];
-
- //算出table的CGRect
- CGRect rect = self.view.bounds;
- int height = _titleArray.count * 44;
- rect.origin.y = rect.size.height - height;
- rect.size.height = height;
-
- _table = [[UITableView alloc]initWithFrame:rect];
- _table.delegate = self;
- _table.dataSource = self;
- [self.view addSubview:_table];
-
- }

這個菜單你可以任意自訂,我這裡是一個tableView,你可以寫一些有圖和文字的添加上去。只需要把原始碼稍改,就ok!
