平时我们都是用UITextFeild 来写搜索框， 最近有时间就自己重新封装了UISearchBar, 他可以自行修改里面的属性来达到我们使用的要求。
源代码下载地址:https://github.com/liguoliangiOS/LGLSearchBar.git 欢迎各位下载使用，有问题可以qq联系我 185226139 如果觉得好用请给我点赞，谢谢！
这个使用简单：
#import "LGLSearchBar.h"
LGLSearchBar * searchBar = [[LGLSearchBar alloc] initWithFrame:CGRectMake(10, 200, SCREENWIDTH - 20, 40) searchBarStyle:LGLSearchBarStyleDefault];
[searchBar searchBarTextSearchTextBlock:^(NSString *searchText) {
NSLog(@"%@", searchText);
}];
下面上具体的代码
LGLSearchBar.h
#import <Foundation/Foundation.h>
#import <UIKit/UIKit.h>
typedef void(^SearchTextBlock)(NSString * searchText);
typedef NS_ENUM(NSUInteger, LGLSearchBarStyle) {
LGLSearchBarStyleDefault,
LGLSearchBarStyleProminent,
LGLSearchBarStyleMinimal
};
typedef NS_ENUM(NSInteger, LGLTextBorderStyle) {
LGLTextBorderStyleNone,
LGLTextBorderStyleLine,
LGLTextBorderStyleBezel,
LGLTextBorderStyleRoundedRect
};
