Question

I have created an UISearchBar and I have to insert a view in inputAccessoryView but the compiler gives me this error :

Assignment to readonly property

why this happens ? :

@property(nonatomic,retain)IBOutlet UISearchBar *searchbar;

@property (retain, nonatomic) IBOutlet UIView *keyView;

 self.searchbar.inputAccessoryView = keyView;

Answer 1

SearchBars have a UITextView inside, you could look for it in a slightly dirty way and set the inputAccessoryView to it. I’m not sure if this will work, but it’s worth a shot

UITextField *searchBarField = nil;
for (UIView *subView in searchBar.subviews) {
    if ([subView conformsToProtocol:@protocol(UITextInputTraits)]) {
        searchBarField = (UITextField *)subView;
        searchBarField.inputAccessoryView = ...
        break;
    }
}
