从超级视图中删除多个视图

Question

使用此方法时，我需要同时删除几个UIViews窗体superview ：

[view1 , view 2 , vie3 removeFromSuperview]; 

编译器警告我：

 **warning: Unused Entity Issue: Expression result unused** 

怎么做对？

Answer 1

或者，如果要从某个视图中删除所有子视图：

for (UIView *subview in view.subviews) {
    [subview removeFromSuperview];
}

Answer 2

迅速

view.subviews.forEach { $0.removeFromSuperview() }

目标C

[view.subviews makeObjectsPerformSelector:@selector(removeFromSuperview)];
