在UISearchBar控件中,是否可以将键盘的“搜索”键标题更改为“完成”?

最佳答案

对于名为表searchbar的搜索栏:

// Set the return key and keyboard appearance of the search bar
        for (UIView *searchBarSubview in [tableSearchBar subviews]) {

            if ([searchBarSubview conformsToProtocol:@protocol(UITextInputTraits)]) {

                @try {

                    [(UITextField *)searchBarSubview setReturnKeyType:UIReturnKeyDone];
                    [(UITextField *)searchBarSubview setKeyboardAppearance:UIKeyboardAppearanceAlert];
                }
                @catch (NSException * e) {

                    // ignore exception
                }
            }
        }
