使UItextfield像UISearchBar一样运行 [英] make UItextfield to function like UISearchBar

问题描述

我想改变 UISearchBar 的外观：所以，

I want to change the looks of UISearchBar: So,

如果有办法，我可以使我的 UITextField （在自定义搜索背景中）的功能类似于 UISearchBar ？或继承和覆盖 - （void）layoutSubviews 是唯一的方法吗？

If there's a way by which I can make my UITextField(in a custom background for search) to function like UISearchBar ? or subclassing and overriding the - (void)layoutSubviews is the only way ?

请告诉如何将其子类化!!!

Kindly tell How to subclass it !!!

推荐答案

你可以使用此流号代码更改 UISearchBar 背景。

you can change the UISearchBar background using this bellow code..

for (UIView *subview in searchBar.subviews) {
        if ([subview isKindOfClass:NSClassFromString(@"UISearchBarBackground")]) {
            UIView *bg = [[UIView alloc] initWithFrame:subview.frame];
            bg.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"SkyBackground.jpeg"]];
            [searchBar insertSubview:bg aboveSubview:subview];
            [subview removeFromSuperview];
            break;
        }
    }

从此代码中您可以设置图片或其他任何内容 UISearchBar 的背景。

From this code you can set image or anything else for background of UISearchBar.

更新：

更改取消按钮外观使用此波纹管代码...

for change the Cancel button appearance use this bellow code...

   UIButton *cancelButton = nil;

    for(UIView *subView in searchBar.subviews)
    {
        if([subView isKindOfClass:[UIButton class]])
        {
            cancelButton = (UIButton*)subView;
