AJ分享，必须精品

一：效果

这里写图片描述

二：封装好的工具条

NYComposeToolbar.h

带代理方法

#import <UIKit/UIKit.h>typedef enum {    NYComposeToolbarButtonTypeCamera, // 拍照    NYComposeToolbarButtonTypePicture, // 相册    NYComposeToolbarButtonTypeMention, // @    NYComposeToolbarButtonTypeTrend, // #    NYComposeToolbarButtonTypeEmotion // 表情} NYComposeToolbarButtonType;@class NYComposeToolbar;@protocol NYComposeToolbarDelegate <NSObject>@optional- (void)composeToolbar:(NYComposeToolbar *)toolbar didClickButton:(NYComposeToolbarButtonType)buttonType;@end@interface NYComposeToolbar : UIView@property (nonatomic, weak) id<NYComposeToolbarDelegate> delegate;@end

NYComposeToolbar.m

////  NYComposeToolbar.m//  Created by apple on 14-10-20.//  Copyright (c) 2014年 heima. All rights reserved.//#import "NYComposeToolbar.h"@implementation NYComposeToolbar- (id)initWithFrame:(CGRect)frame{    self = [super initWithFrame:frame];    if (self) {        self.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"compose_toolbar_background"]];        // 初始化按钮        [self setupBtn:@"compose_camerabutton_background" highImage:@"compose_camerabutton_background_highlighted" type:NYComposeToolbarButtonTypeCamera];        [self setupBtn:@"compose_toolbar_picture" highImage:@"compose_toolbar_picture_highlighted" type:NYComposeToolbarButtonTypePicture];        [self setupBtn:@"compose_mentionbutton_background" highImage:@"compose_mentionbutton_background_highlighted" type:NYComposeToolbarButtonTypeMention];        [self setupBtn:@"compose_trendbutton_background" highImage:@"compose_trendbutton_background_highlighted" type:NYComposeToolbarButtonTypeTrend];        [self setupBtn:@"compose_emoticonbutton_background" highImage:@"compose_emoticonbutton_background_highlighted" type:NYComposeToolbarButtonTypeEmotion];    }    return self;}/** * 创建一个按钮 */- (void)setupBtn:(NSString *)image highImage:(NSString *)highImage type:(NYComposeToolbarButtonType)type{    UIButton *btn = [[UIButton alloc] init];    [btn setImage:[UIImage imageNamed:image] forState:UIControlStateNormal];    [btn setImage:[UIImage imageNamed:highImage] forState:UIControlStateHighlighted];    [btn addTarget:self action:@selector(btnClick:) forControlEvents:UIControlEventTouchUpInside];    btn.tag = type;    [self addSubview:btn];}- (void)layoutSubviews{    [super layoutSubviews];    // 设置所有按钮的frame    NSUInteger count = self.subviews.count;    CGFloat btnW = self.width / count;    CGFloat btnH = self.height;    for (NSUInteger i = 0; i<count; i++) {        UIButton *btn = self.subviews[i];        btn.y = 0;        btn.width = btnW;        btn.x = i * btnW;        btn.height = btnH;    }}- (void)btnClick:(UIButton *)btn{    if ([self.delegate respondsToSelector:@selector(composeToolbar:didClickButton:)]) {//        NSUInteger index = (NSUInteger)(btn.x / btn.width);        [self.delegate composeToolbar:self didClickButton:btn.tag];    }}@end

三：调用

设置代理并且实现代理方法

/** * 添加工具条 */- (void)setupToolbar{    NYComposeToolbar *toolbar = [[NYComposeToolbar alloc] init];    toolbar.width = self.view.width;    toolbar.height = 44;    toolbar.y = self.view.height - toolbar.height;    toolbar.delegate = self;    [self.view addSubview:toolbar];    self.toolbar = toolbar;}

代理方法

#pragma mark - NYComposeToolbarDelegate- (void)composeToolbar:(NYComposeToolbar *)toolbar didClickButton:(NYComposeToolbarButtonType)buttonType{    switch (buttonType) {        case NYComposeToolbarButtonTypeCamera: // 拍照//            [self openCamera];            NYLog(@"--- 拍照");            break;        case NYComposeToolbarButtonTypePicture: // 相册            NYLog(@"--- 相册");//            [self openAlbum];            break;        case NYComposeToolbarButtonTypeMention: // @            NYLog(@"--- @");            break;        case NYComposeToolbarButtonTypeTrend: // #            NYLog(@"--- #");            break;        case NYComposeToolbarButtonTypeEmotion: // 表情\键盘            NYLog(@"--- 表情");            break;    }}
