UISearchBar在iOS8中自定义InputView崩溃

Question

我有UISearchBar与自定义InputView。现在我无法在iOS8中为UISearchBar设置自定义输入视图。它正在崩溃。

这是我如何设置自定义InputView为的UISearchBar

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

       [[[(UITextField*)[self.sBar.subviews objectAtIndex:0] subviews] objectAtIndex:i] setInputView:MyKeyboard]; 
      } 

这里是崩溃日志。

Could not load the "" image referenced from a nib in the bundle with identifier "com.company.MyApp" 
2014-09-23 13:34:13.816 MyApp[1651:61729] Could not load the "" image referenced from a nib in the bundle with identifier "com.company.MyApp" 

它在iOS 7中正常工作，但现在在iOS8中崩溃。

我该如何解决？

我得到了我自己的问题的答案。

但是，您需要先检查iOS版本iOS8，因为此代码不适用于iOS7。

if([systemVersion isEqualToString:@"8"]) 
    { 
     UITextField *search = (UITextField *)[[[self.sBar.subviews objectAtIndex:0] subviews] objectAtIndex:0]; 
     [search setFont:[UIFont fontWithName:@"MyCustomFont" size:15]]; 
     [search setInputView:self.customKeyboard]; 
     [search setTextColor:[UIColor whiteColor]]; 
     [self.customKeyboard setTextView:search]; 

     [search reloadInputViews]; 
    }
