(簡(jiǎn)書能不能出個(gè)視頻轉(zhuǎn)換成gif的功能,或者上傳視頻...好吧 好像都不顯示,湊合看吧---示意圖)

需求:視圖可能會(huì)彈在任何頁面上,要求不能阻礙底部視圖的響應(yīng),點(diǎn)擊關(guān)閉按鈕可以關(guān)閉視圖

1.可以禁止視圖的userInteractionEnabled,但是按鈕也要計(jì)算好 也是添加到window上,比較low
2.重寫彈出視圖的hitTest

- (UIView *)hitTest:(CGPoint)point withEvent:(UIEvent *)event {
    int count = (int)self.subviews.count;
    //遍歷子視圖
    for (int i = count - 1; i >= 0; i--){

        UIView *cV = self.subviews[i];
        //轉(zhuǎn)換坐標(biāo)
        CGPoint cP =[self convertPoint:point toView:cV];
        
        UIView *fitView =[cV hitTest:cP withEvent:event];
        
        if (fitView) {
            return fitView;
        }
    }
    //window會(huì)遍歷到 底部視圖 讓底部視圖響應(yīng)
    return nil;
}
