UITextField 無法顯示第三方輸入法情況,同時有2個UITextField,取名為:賬號和密碼,
密碼secureTextEntry = YES; 密碼frame必須在賬號下方,同時不能hidden = YES;高度必須大于1,可以enabled = NO;這樣賬號就可以禁止第三方輸入法了,但是會顯示密碼填充對話框
據(jù)說是iOS10 才有這個功能

UITextField *nameTF = [[UITextField alloc]init];
nameTF.backgroundColor = UIColor.orangeColor;
[self.containerView addSubview:nameTF];
        [nameTF mas_makeConstraints:^(MASConstraintMaker *make) {
            make.top.equalTo(self.bottomAttribute).mas_offset(20);
            make.left.mas_equalTo(10);
            make.right.mas_equalTo(-10);
            make.height.mas_equalTo(50);
        }];

  UITextField *pswTF = [[UITextField alloc]init];
        pswTF.backgroundColor = UIColor.clearColor;
        pswTF.secureTextEntry = YES;
        pswTF.enabled = NO;
        [self.containerView addSubview:pswTF];
        [pswTF mas_makeConstraints:^(MASConstraintMaker *make) {
            make.top.equalTo(self.bottomAttribute).mas_equalTo(10);
            make.left.mas_equalTo(10);
            make.right.mas_equalTo(-10);
            make.height.mas_equalTo(1.0);
        }];
