自定义UITextField背景图片

         我们经常会看见很多漂亮的UITextField,但是系统的UITextField还是相对比较简单的,往往并不能符合我们的需求。那到底该怎么实现呢,其实也不是很难,只要我们新建一个类继承UITextField,重新drawRect即可。

    我们新建一个CustomTextField 类,继承UITextField.  

     主要代码:

    .h文件代码

#import <UIKit/UIKit.h>

@interface mCustomTextField : UITextField

@end

    .m文件实现代码:

//
//  mCustomTextField.m
//  MapDemo

#import "mCustomTextField.h"

@implementation mCustomTextField

- (id)initWithFrame:(CGRect)frame
{
    self = [super initWithFrame:frame];
    if (self) {
        // Initialization code
    }
    return self;
}

-(CGRect)textRectForBounds:(CGRect)bounds
{
    return CGRectInset(bounds, 5, 0);
}

-(CGRect)editingRectForBounds:(CGRect)bounds
{
    return CGRectInset(bounds,5,0);
}


-(void)drawRect:(CGRect)rect
{
    UIImage * backgroundImage = [[UIImage imageNamed:@"text_field_teal.png"] resizableImageWithCapInsets:UIEdgeInsetsMake(15.0, 5.0, 15.0, 5.0)];
    
    
    [backgroundImage drawInRect:[self bounds]];
}

/*
// Only override drawRect: if you perform custom drawing.
// An empty implementation adversely affects performance during animation.
- (void)drawRect:(CGRect)rect
{
    // Drawing code
}
*/

@end
