下面你会发现我的.h& .m文件为我的主视图控制器.
我有3个问题.
因为我有多个uitextfields,我必须设置每个自己的resignFirstResponder语句？和2.)我该怎么办,用什么方法？我的语法是否适合辞退第一位回复者？
此外,如果用户点击该字段而不是按返回键,我可以解除键盘,这将是非常好的！
我知道这已经被问到和回答了,但老实说,我还是有点困惑,在哪里.
我正在使用XCode 5和iOS 7的故事板.
=============================
.h文件
@interface ViewController : UIViewController <UITextFieldDelegate,UITableViewDelegate,UITableViewDataSource> @property (weak,nonatomic) IBOutlet UITextField *danceDate; @property (weak,nonatomic) IBOutlet UITextField *dancePlace; @property (weak,nonatomic) IBOutlet UITextField *danceTerminal; @property (weak,nonatomic) IBOutlet UITextField *danceGate;
.m文件
#import "ViewController.h"
@interface ViewController ()
@end
@implementation ViewController
- (void)viewDidLoad
{
[super viewDidLoad];
[self retrieveFromParse];
self.tableView.dataSource = self;
self.tableView.delegate = self;
self.navigationItem.rightBarButtonItem = self.editButtonItem;
// SET DELEGATE HERE
//
// if I uncomment 1 of these lines,i'll get an error.
//
// _dancePlace.delegate = self;
// dancePlace.delegate = self;
// dancePlace = self;
}
- (void)textFieldDidBeginEditing:(UITextField *)textField
{
}
-(BOOL) textFieldShouldReturn: (UITextField *) textField
{
[textField resignFirstResponder];
return YES;
}
-(BOOL) textFieldShouldReturn: (UITextField *) textField
{
return YES;
}
解决方法
调换textField：
您的所有textField.delegate都应设置为ViewController的对象.
然后执行下面的代理方法.

-(BOOL) textFieldShouldReturn: (UITextField *) textField {
[textField resignFirstResponder];
return YES;
}
点击视图关闭键盘：
将点击手势添加到ViewController.view中,如下所示：
//declare a property to store your current responder
@property (nonatomic,assign) id currentResponder;
//in viewDidLoad:
UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(resignOnTap:)];
[singleTap setNumberOfTapsrequired:1];
[singleTap setNumberOftouchesrequired:1];
[self.view addGestureRecognizer:singleTap];
[singleTap release];
//Implement the below delegate method:
- (void)textFieldDidBeginEditing:(UITextField *)textField {
self.currentResponder = textField;
}
//Implement resignOnTap:
- (void)resignOnTap:(id)iSender {
[self.currentResponder resignFirstResponder];
}
// was missing ; after the call --> [self.currentResponder resignFirstResponder]
// also in textFieldDidEndEditing set self.currentResponder = nil;
