iOS添加到購物車的簡單動畫效果
#pragma mark - 添加到購物車的動畫效果
// huangyibiao
- (void)addAnimatedWithFrame:(CGRect)frame {
// 該部分動畫 以self.view為參考係進行
frame = [[UIApplication sharedApplication].keyWindow convertRect:frame fromView:self.RFcell.headBtn];
UIButton *move = [[UIButton alloc] initWithFrame:frame];
[move setBackgroundColor:UIColorFromRGB(0xFFA215)];
[move setTitle:self.RFcell.headBtn.currentTitle forState:UIControlStateNormal];
[move setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];
move.contentMode = UIViewContentModeScaleToFill;
[[UIApplication sharedApplication].keyWindow addSubview:move];
// 加入購物車動畫效果
[UIView animateWithDuration:1.2 animations:^{
move.frame = CGRectMake(320 - frame.size.width - 20, 24,
frame.size.width, frame.size.height);
} completion:^(BOOL finished) {
[move removeFromSuperview];
if (self.cartCategoriesLabel == nil) {
self.cartCategoriesLabel = [[UILabel alloc] initWithFrame:CGRectMake((16 - 8) / 2, (16 - 8) / 2, 8, 8)];
self.cartCategoriesLabel .textColor = [UIColor whiteColor];
self.cartCategoriesLabel .backgroundColor = [UIColor clearColor];
self.cartCategoriesLabel .textAlignment = NSTextAlignmentCenter;
self.cartCategoriesLabel .font = [UIFont systemFontOfSize:9];
UIImageView *imgView = [[UIImageView alloc] initWithFrame:CGRectMake(15, 8, 16, 16)];
imgView.image = [UIImage imageNamed:@"news"];
[imgView addSubview:self.cartCategoriesLabel];
[self.cartButton addSubview:imgView];
}
self.cartCategoriesLabel .text = [NSString stringWithFormat:@"%d", _cartCategories.count];
}];
return;
}
frame參數是按鈕的frame，也就是原來所在父視圖上的Frame
這裏會將原來的frame轉換成window上的frame
在動畫完成後，更新顯示購物車中的商品種類數
