UISearchBar的自定义InputView在iOS7中不起作用

Question

我需要在UISearchBar中设置我的自定义inputView.

所以我写了以下代码,这在iOS5和iOS6中完美运行.

但它在iOS7中不起作用.

for(int i =0; i<[self.searchBar.subviews count]; i++) {
            if([[self.searchBar.subviews objectAtIndex:i] isKindOfClass:[UITextField class]])
            {
                [(UITextField*)[searchBar.subviews objectAtIndex:i] setFont:[UIFont fontWithName:@"MyCustomFont" size:15]];
                UITextField* search=(UITextField*)[searchBar.subviews objectAtIndex:i];
                search.delegate = self;

                [(UITextField*)[self.searchBar.subviews objectAtIndex:i] setInputView:self.customKeyboard];
                [self.customKeyboard setTextView:search];
            }
        }



        [self.sBar reloadInputViews];

我怎样才能做到这一点？

在iOS7中更改了searchBar子视图层次结构,请尝试以下操作:

IOS 7:

NSArray *searchBarSubViews = [[self.searchBar.subviews objectAtIndex:0] subviews];

iOS6及之前:

NSArray *searchBarSubViews =  self.searchBar.subviews;

尝试以下更新功能:

NSArray *searchBarSubViews = [[self.searchBar.subviews objectAtIndex:0] subviews];
for(int i =0; i<[searchBarSubViews count]; i++) {
    if([[searchBarSubViews objectAtIndex:i] isKindOfClass:[UITextField class]])
    {
        UITextField* search=(UITextField*)[searchBarSubViews objectAtIndex:i];
        [search setFont:[UIFont fontWithName:@"MyCustomFont" size:15]];
        search.delegate = self;

        [search setInputView:self.customKeyboard];
        [self.customKeyboard setTextView:search];
    }
}
[self.sBar reloadInputViews];
