ios菜鸟之路：textfield隐藏键盘以及点击背景取消键盘

一、点击Done按键隐藏键盘：

//在头文件.h中 初始化

@property (strong, nonatomic) IBOutlet UITextField *account_reg_TextField;

@property (strong, nonatomic) IBOutlet UITextField *passwd_reg_TextField;

@property (strong, nonatomic) IBOutlet UITextField *check_passwd_reg_TextField;

//action 事件选择 did end on exit

- (IBAction)textfieldDoneEditing:(id)sender;

- (IBAction)paswdDoneEditng:(id)sender;

- (IBAction)checkpasswdDoneEditing:(id)sender;

//在.m文件中实现方法

- (IBAction)textfieldDoneEditing:(id)sender {

[account_reg_TextField resignFirstResponder];

}

- (IBAction)paswdDoneEditng:(id)sender {

[passwd_reg_TextField resignFirstResponder];

}

- (IBAction)checkpasswdDoneEditing:(id)sender {

[check_passwd_reg_TextField resignFirstResponder];

}

二、帅帅的背景点击取消键盘

选择视图，在最右边的custom class中选择UIButton 即把背景改成了button事件

- (IBAction)backgroundbutton:(id)sender;

//.m文件的实现

- (IBAction)backgroundbutton:(id)sender {

[account_reg_TextField resignFirstResponder];

[passwd_reg_TextField resignFirstResponder];

[check_passwd_reg_TextField resignFirstResponder];

}

可以了吧 嘻嘻
