1.1 設置返回鍵樣式

textField.returnKeyType=UIReturnKeyDone;

1.2 設置邊框樣式

textField.borderStyle=UITextBorderStyleRoundedRect;

1.3 一鍵刪除

textField.clearButtonMode=UITextFieldViewModeAlways;

1.4 密文

textField.secureTextEntry=NO;

1.5 添加左右視圖

UIImage *image=[UIImage imageNamed:@"account_candou"];

UIImageView *imageview=[[UIImageView alloc]initWithFrame:CGRectMake(0,0 ,
 50, 50)];

imageview.image=image;

textField.leftView=imageview;

textField.leftViewMode=UITextFieldViewModeAlways;

1.6 監(jiān)聽鍵盤出現(xiàn)

1.出現(xiàn)

[[NSNotificationCenter defaultCenter] addObserver:self 
selector:@selector(keyboardWillShow:) 
name:UIKeyboardWillShowNotification object:nil];

2.消失

[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(keyboardWillHidden:) 
name:UIKeyboardWillHideNotification object:nil];

3.實現(xiàn)方法

- (void)keyboardWillShow:(NSNotificationCenter *)noti{
    
    self.tableView.frame = CGRectMake(0, 0, 
    SCREEN_WIDTH, SCREEN_HEIGHT - 280);
    
}

- (void)keyboardWillHidden:(NSNotificationCenter *)noti{
    
    self.tableView.frame = CGRectMake(0, 0, SCREEN_WIDTH, SCREEN_HEIGHT);
    
}

1.7 放棄第一響應者

- (BOOL)textFieldShouldReturn:(UITextField *)textField;
{
[textField resignFirstResponder];

return YES;

}

1.8 數(shù)字鍵盤

textField.keyboardType = UIKeyboardTypePhonePad;

1.9 手機號驗證

記得寫代理

- (BOOL)textField:(UITextField*)textField 
shouldChangeCharactersInRange:(NSRange)range 
            replacementString:(NSString*)string {
    NSCharacterSet *cs;
    
    cs = [[NSCharacterSet characterSetWithCharactersInString:@"0123456789"] 
    invertedSet];
    
    NSString*filtered = [[string componentsSeparatedByCharactersInSet:cs]
                        componentsJoinedByString:@""];
    
    BOOL basicTest = [string isEqualToString:filtered];
    
    if(!basicTest) {
        
        return NO;
        
    }
    
    NSString *temp = [textField.text 
                stringByReplacingCharactersInRange:range 
                                        withString:string];
    
    if (temp.length > 11) {
        
        return NO;
        
    }
    
    return YES;
    
}

1.10 return鍵點擊

- (BOOL)textFieldShouldReturn:(UITextField *)textField{

    return YES;

}
