UITextField总结

<div id="cnblogs_post_body">1.UITextField的初始化及设置
searchTextField=[[UITextField alloc]initWithFrame:CGRectMake(1.0,0.0,searchBackGroundImageView.frame.size.width, searchBackGroundImageView.frame.size.height)];//创建一个UITextField对象，及设置其位置及大小
    searchTextField.contentVerticalAlignment=UIControlContentVerticalAlignmentCenter;//设置其输入内容竖直居中
    UIImageView* imgV=[[UIImageViewalloc]initWithImage:[UIImageimageNamed:@"search_ico"]];
    searchTextField.leftView=imgV;//设置输入框内左边的图标
    searchTextField.leftViewMode=UITextFieldViewModeAlways;
    searchTextField.placeholder=@"请输入关键字";//默认显示的字
    searchTextField.secureTextEntry=YES;//设置成密码格式
    searchTextField.keyboardType=UIKeyboardTypeDefault;//设置键盘类型为默认的
    searchTextField.returnKeyType=UIReturnKeyDefault;//返回键的类型
    searchTextField.delegate=self;//设置委托
2.可以通过委托方法关闭键盘
-(BOOL)textFieldShouldReturn:(UITextField*)textField
{
   [searchTextField resignFirstResponder];
  return YES;
}
3.聚焦方法
[searchTextField becomeFirstResponder];
