How to check if subview is button or not - ios

Question

I am developing an application. In that I get all subviews of UITableViewCell.
The code for this one is:
(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];
}
}
But my problem is how to find out button from that subviews list. Please tell me how to solve this one.

Answer 1

You can iterate through all subviews like this.
for (id subview in subviews) {
if ([subview isKindOfClass:[UIButton class]]) {
//do your code
}
}

Answer 2

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

Answer 3

Check if the subview is a button with is AnyClass, isKind(of aClass: AnyClass) or isMember(of aClass: AnyClass) API.
Using is-
for subview in self.view.subviews{
if subview is UIButton{
//do whatever you want
}
}
Using isMember(of:)-
for subview in self.view.subviews{
if subview.isMember(of: UIButton.self){
//do whatever you want
}
}
Using isKind(of:)-
for subview in self.view.subviews{
if subview.isKind(of: UIButton.self){
//do whatever you want
}
}

Answer 4

To expand on the 'do your code' part of Martin's answer. Once I got the subview, I wanted to test whether it was the right button and then remove it. I can't check the titleLabel of the button directly by using subview.titleLabel so I assigned the subview to a UIButton and then checked the button's titleLabel.
- (void)removeCheckboxes {
for ( id subview in self.parentView.subviews ) {
if ( [subview isKindOfClass:[UIButton class]] ) {
UIButton *checkboxButton = subview;
if ( [checkboxButton.titleLabel.text isEqualToString:#"checkBoxR1C1"] ) [subview removeFromSuperview];
}
}
}
