Ios 如何将textfield输入视图设置为搜索栏?
我已经尝试得到正确的解决方案,但我不能任何程序员请给我一个想法如何使 1.是否可以将uitextfield设置为uisearchbarIos 如何将textfield输入视图设置为搜索栏?,ios,objective-c,uitextfield,uisearchbar,Ios,Objective C,Uitextfield,Uisearchbar,我已经尝试得到正确的解决方案,但我不能任何程序员请给我一个想法如何使 1.是否可以将uitextfield设置为uisearchbar UISearchBar *search=[[UISearchBar alloc]init]; search.delegate=self; [_txtLocation setInputView:search]; 2.当用户键入所需的值时,我会在文本字段底部将其显示为覆盖 3.请帮我找出解决办法 In.h文件 #import <UIKit/
UISearchBar *search=[[UISearchBar alloc]init];
search.delegate=self;
[_txtLocation setInputView:search];
2.当用户键入所需的值时,我会在文本字段底部将其显示为覆盖
3.请帮我找出解决办法 In.h文件
#import <UIKit/UIKit.h>
@interface SEMainVC : UIViewController <UITextFieldDelegate>{
NSMutableArray *dummyArray;
NSMutableArray *searchArray;
NSString *searchTextString;
}
@property (weak, nonatomic) IBOutlet UITextField *searchTextField;
@property (weak, nonatomic) IBOutlet UITableView *contentTableView;
- (void) setupData;
@end
要使文本字段像搜索栏一样工作,请实现
-(BOOL)textField:(UITextField*)textField
应更改字符范围:(NSRange)范围
replacementString:(NSString*)string
UITextField的委托方法。所以,基本上,您需要实现自动完成功能,这就是您如何做到的。
要检测触发了哪个textfield,请将标记分配给textfield

对于表视图,我想再添加一个视图控制器或当前视图控制器就足够了。这取决于您的要求。您可以再添加一个视图控制器或当前视图控制器就足够了。您可以直接使用textfield进行搜索您是否希望自动填充该文本字段,对吗?@ShrikantKankatti是您更正了确定您希望自动填充UItextfield,对吗?所以我可以发布我的答案。是的,发布你的答案对我有帮助@Shrikantkankatii有疑问,4 uitextfeld被放在我的故事板中,我如何为特定的文本字段给出这个所有方法都可以使用@selector?@KishoreKumar请检查我的答案。@KishoreKumar更新了2个文本字段的答案。检查一下。我按照你的建议给出了所有内容@Rumin,但没有发生任何事情我认为我这边有问题。@KishoreKumar如果你尝试其他人的答案,请评论他/她的答案。不管怎样,你试过我的吗?
