#import "CZSearchBar.h"

 

@implementation CZSearchBar

 

- (instancetype)initWithFrame:(CGRect)frame

{

    if (self = [super initWithFrame:frame]) {

        

        self.font = [UIFont systemFontOfSize:13];

        

        self.background = [UIImage imageWithStretchableName:@"searchbar_textfield_background"];

        

        // 设置左边的view

        // initWithImage:默认UIImageView的尺寸跟图片一样

        UIImageView *imageV = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"searchbar_textfield_search_icon"]];

        imageV.width += 10;

        imageV.contentMode = UIViewContentModeCenter;

        self.leftView = imageV;

        // 一定要设置，想要显示搜索框左边的视图，一定要设置左边视图的模式

        self.leftViewMode = UITextFieldViewModeAlways;

        

    }

    return self;

}
