也是收藏的别的大神分享的

1、项目源码/Demo分享：项目源码

2、iOS的Touch ID验证：touch验证

3、设置textField的placeHolds的字体颜色：[pwdTextFieldsetValue:[UIColor lightGrayColor]forKeyPath:@"_placeholderLabel.textColor"];

---

4、设置textField的placeHolds的字体大小：[pwdTextFieldsetValue:[UIFont boldSystemFontOfSize:15]forKeyPath:@"_placeholderLabel.font"];

5、设置textFiled的左视图 占位符 ……的间距；

//控制左视图位置

- (CGRect)leftViewRectForBounds:(CGRect)bounds

{

    CGRecticonRect = [superleftViewRectForBounds:bounds];

    iconRect.origin.x+=8;

     //右偏8

     returniconRect;

}

//控制placeHolder的位置，左右缩40

-(CGRect)placeholderRectForBounds:(CGRect)bounds

{

      CGRect inset =CGRectMake(bounds.origin.x+40, bounds.origin.y+2,                   bounds.size.width-10, bounds.size.height);

      return inset;

}

//控制显示文本的位置

-(CGRect)textRectForBounds:(CGRect)bounds

{

      CGRect inset =CGRectMake(bounds.origin.x+40, bounds.origin.y+2,                 bounds.size.width-10, bounds.size.height);

      return inset;

}

//控制编辑文本的位置

-(CGRect)editingRectForBounds:(CGRect)bounds

{

    CGRect inset =CGRectMake(bounds.origin.x+40, bounds.origin.y+2,                 bounds.size.width-10, bounds.size.height);

   return inset;

}

//控制清除按钮的位置

-(CGRect)clearButtonRectForBounds:(CGRect)bounds

{

returnCGRectMake(bounds.origin.x+ bounds.size.width-50, bounds.origin.y+ bounds.size.height-20,16,16);

}
