iOS 7 如何获取当前选定的 UITextField id

Question

调用 dismissKeyboard 时，我将每个 UITextField 添加到 resignFirstResponder。

有没有办法获取当前选定的 UITextField 的 ID 并使其成为 resignFirstResponder？

#import "NewBabyViewController.h"

@interface NewBabyViewController ()
@property (weak, nonatomic) IBOutlet UITextField *BabyName;
@property (weak, nonatomic) IBOutlet UITextField *BabyNickname;    
@end

@implementation NewBabyViewController

- (void)viewDidLoad
{
    UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc]
                                   initWithTarget:self
                                   action:@selector(dismissKeyboard)
                                   ];
    [self.view addGestureRecognizer:tap];
}

-(void)dismissKeyboard{

    [self.view endEditing:YES];
    //[self.BabyName resignFirstResponder];
    //[self.BabyNickname resignFirstResponder];
}

-(IBAction)textFieldDone:(id)sender
{
    [sender resignFirstResponder];
}

@end

这个问题的解决方案并不十分明显，但实际上非常容易解决。只需使用以下内容:

-(void)dismissKeyboard {
    [self.view endEditing:YES];
}
