UISearchBar的自定义InputView无法在iOS7中工作

Question

我需要在UISearchBar中设置自定义inputView。

所以我写了下面的代码，这是在iOS5和iOS6完美工作。

但是它在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]; 

我该怎么做？

搜索栏子视图层次结构中iOS7被更改，请尝试以下：

iOS7：

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

iOS6的之前：

NSArray *searchBarSubViews = self.searchBar.subviews; 

尝试下面更新功能：

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];
