UITextField调整内容位置及左右视图LeftView、RightView

Sian

// 清除按钮左移一个单元

- (CGRect)clearButtonRectForBounds:(CGRect)bounds

{

    CGRect rect = [super clearButtonRectForBounds:bounds];

    if (_isReservedRightView){

        rect = CGRectOffset(rect, -rect.size.width, 0);

    }

    return rect;

}

// 控制 placeHolder 的位置，左右缩 10

- (CGRect)textRectForBounds:(CGRect)bounds

{

    CGRect rect = [super textRectForBounds:bounds];

    return CGRectInset(rect, 8, 0);

}

// 控制文本的位置，左右缩 10

- (CGRect)editingRectForBounds:(CGRect)bounds

{

    CGRect rect = [super textRectForBounds:bounds];

    return CGRectInset(rect, 8, 0);

}

// 重写方法，固定viewMode为Always

- (void)setLeftView:(UIView *)leftView

{

    [super setLeftView:leftView];

    self.leftViewMode = UITextFieldViewModeAlways;

}

注意：clearButton即rightView，如果设置了rightView，clearButton就不会再出现！
