如何检查子视图是否为按钮

Question

我正在开发一个应用程序.在那里我获得了UITableViewCell的所有子视图.

这个代码是:

    (void)listSubviewsOfView:(UIView *)view {

    // Get the subviews of the view
         NSArray *subviews = [view subviews];

    // Return if there are no subviews
    if ([subviews count] == 0) return;

    for (UIView *subview in subviews) {

        NSLog(@"%@", subview);

        // List the subviews of subview
        [self listSubviewsOfView:subview];
    }
}

但我的问题是如何找出该子视图列表中的按钮.请告诉我如何解决这个问题.

Answer 1

您可以遍历所有这样的子视图.

for (id subview in subviews) {
   if ([subview isKindOfClass:[UIButton class]]) {
      //do your code
   }
}

Answer 2

迅速

for subview in view.subviews {
    if subview is UIButton {
        // this is a button
    }
}
