自定义textField继承自UITextField

重写

- (CGRect)placeholderRectForBounds:(CGRect)bounds

_phoneTF.font = HPFontSemibold(16); // 设置输入文字字号

[_phoneTF setValue:[UIFont systemFontOfSize:14] forKeyPath:@"_placeholderLabel.font"]; // 设置placeholder字号

// 设置删除按钮的图片

UIButton *button = [_phoneTF valueForKey:@"_clearButton"];
[button setImage:[UIImage imageNamed:@"icon_login_closed_round"] forState:UIControlStateNormal];
_phoneTF.clearButtonMode = UITextFieldViewModeWhileEditing;

- (CGRect)clearButtonRectForBounds:(CGRect)bounds { // 设置删除按钮的位置
return CGRectMake(bounds.origin.x + bounds.size.width - 20, (bounds.size.height - 20) * 0.5, 20, 20);
}

// 设置textField右边的view

_passwordTF.rightView = phoneCodeBtn;
_passwordTF.rightViewMode = UITextFieldViewModeAlways;
_passwordTF.rightView.hidden = YES;
