Customkeyboard用FPGA实现的UISearchBar？(Customkeyboard

我尝试实施customkeyboard用的UISearchBar。首先我所有mainclass.h在哪里我使用的UISearchBar是这个样子

#import <UIKit/UIKit.h>
#import <QuartzCore/QuartzCore.h>

@class PashtoKeyboard;
@class SearchBar;
@interface MainViewController : UIViewController<UISearchBarDelegate > {
  IBOutlet SearchBar *searchBar;
  PashtoKeyboard            *pashtoKeyboard;
}
@property(nonatomic,retain)     PashtoKeyboard  *pashtoKeyboard;
@property (nonatomic,retain) SearchBar *searchBar;
@end

现在我mainclass.m

#import "MainViewController.h"
#import "PashtoKeyboard.h"
#import "SearchBar.h"
@implementation MainViewController
@synthesize pashtoKeyboard,searchBar;
- (void)viewDidLoad
{
[super viewDidLoad];
//Create Pashto Keyboard
 PashtoKeyboard *pashtoKey = [[PashtoKeyboard alloc] initWithFrame:CGRectMake(0.0, 460.0-216.0, 320.0, 216.0)];
[pashtoKey loadView];
//[self.view addSubview:hebKey];
[pashtoKey addTarget:self action:@selector(pashtoKeyboard_clicked:) forControlEvents:1001];
[pashtoKey addTarget:self action:@selector(pashtoKeyboardBackspace_clicked:) forControlEvents:1002];
[pashtoKey addTarget:self action:@selector(pashtoKeyboardEnter_clicked:) forControlEvents:1003];
[self setPashtoKeyboard:pashtoKey];
//[hebKey setHidden:YES];
[pashtoKey release];
    searchBar.inputView = pashtoKey;
    searchBar.delegate=self;
    searchBar.userInteractionEnabled=YES;
   }

#pragma mark Pashto Keyboard Methods
 - (void) pashtoKeyboard_clicked:(id)sender{    
   [searchBar setText:[pashtoKeyboard keyboardText]];
   }
 - (void) pashtoKeyboardBackspace_clicked:(id)sender{   
   [searchBar setText:[pashtoKeyboard keyboardText]];
   }
 - (void) pashtoKeyboardEnter_clicked:(id)sender{   
   [searchBar setText:[pashtoKeyboard keyboardText]];
   }

在SearchBar.h

#import <UIKit/UIKit.h>
@interface SearchBar : UISearchBar {
}
@property (readwrite, retain) UIView *inputView;
@end

在SearchBar.m

#import "SearchBar.h"
@implementation SearchBar
@synthesize inputView;
- (void)dealloc {
[super dealloc];
}
@end

然后最后我有PashtoKeyboard.h和PashtoKeyboard.m哪里创建我的自定义键盘，由于大的编码不是我在这里展示这些类的代码，我测试了它与textveiw和文本框。但它不工作的UISearchBar一些。可一个指导我怎么做this.thanx

您需要设置inputView的的UITextField的UISearchBar是为了获取用户输入使用。您可以通过搜索栏的搜索子视图和寻找文本字段做到这一点。这增加了viewDidLoad你的方法mainclass ：

for (UIView *view in searchBar.subviews) {
    if ([view isKindOfClass: [UITextField class]]) {
        UITextField *textField = (UITextField *)view;
        textField.inputView = // Your custom keyboard (PashtoKeyboard)
        break;
    }
}
