iOS(四)动漫App:四

本次主要讲中间的三个按钮以及tableViewCell

先说说中间那三个按钮吧;其实这是我留下的一个坑,因为我就用了个xib,然后再xib里定义它的位置和大小,以及背景图片,再.m写了代理被点击后触发的函数,当然触发还是空白的,但我留着这三个按钮,主要是因为当时为了让它适配iPhone4和iPhone5的屏幕,三个按钮里屏幕边框的距离,三个按钮之间的间距,上下间距,着实让我头疼了很久,结果再xib里设置了一下Autoresizing(感觉没这个简单),勉强的解决了


代码也是相对的简单

HomeheaderView.h

#import <UIKit/UIKit.h>

@protocol HomeheaderViewDelegate;

@interface HomeheaderView : UIView
{
    __weak id<HomeheaderViewDelegate> _delegate;
}

@property(weak,nonatomic)id<HomeheaderViewDelegate> delegate;
@property(weak,nonatomic)IBOutlet UIButton *recommendButton;
@property(weak,nonatomic)IBOutlet UIButton *comicButton;
@property(weak,nonatomic)IBOutlet UIButton *animationButton;

@end

@protocol HomeheaderViewDelegate <NSObject>

@optional
-(void)didClickButton:(UIButton *)sender;

@end

HomeheaderView.m

#import "HomeheaderView.h"

@implementation HomeheaderView

-(void)awakeFromNib{
    [_recommendButton addTarget:self action:@selector(click:) forControlEvents:UIControlEventTouchUpInside];
    [_comicButton addTarget:self action:@selector(click:) forControlEvents:UIControlEventTouchUpInside];
    [_animationButton addTarget:self action:@selector(click:) forControlEvents:UIControlEventTouchUpInside];
    
}

-(void)click:(UIButton *)sender{
    if (!_delegate) {
        NSLog(@"delegate is nil");
    }else{ NSLog(@"delegate is exist");}
    if([_delegate respondsToSelector:@selector(didClickButton:)])
    {
        [_delegate didClickButton:sender];
    }
}

@end

HomeheaderView.xib


接着讲人气动画与人气漫画


这个明显是用了tableView和tableViewCell

HomepageViewController.xib拖了一个tableview控件(其实只要用代码定义就行了。。。当时太年轻)

#import "BaseViewController.h"
#define kSectionX kScreenWidth/2 - 75
#define kSectionY 10
#define kSectionWidth 150
#define kSectionHeight 20
#define kScreenWidth        [UIScreen mainScreen].bounds.size.width
#define kScreenHeight       [UIScreen mainScreen].bounds.size.height
#define kTabBarHeight       self.tabBar.frame.size.height
#define kZSGBgColor         [UIColor colorWithRed:254.f/255.f green:87.f/255.f blue:178.f/255.f alpha:1]
@class HomeheadScroll;
@interface HomepageViewController : BaseViewController
@property(strong,nonatomic)IBOutlet HomeheadScroll *homeScrollView;
@property(weak,nonatomic)IBOutlet UITableView *homePageTableView;<span style="white-space:pre">	</span>//tableView

@property(nonatomic,copy)NSMutableArray *block_name;
@property(nonatomic,copy)NSMutableArray *block_picture;
@property(nonatomic,copy)NSMutableArray *block_intro;

@end


tableView的代理

每一个代理前都已经写明了这个函数的作用

#pragma mark- tableView的函数

//返回tableView的分组数
-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView{
    return 3;
}

//为一个section添加一个header view
- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section {
    if (section == 1) {
        
        return [self viewAndImageName:@"new_comic"];
    }else if (section == 2) {
        
        return [self viewAndImageName:@"new_animation"];
    }
    return nil;
}

- (UIView *)viewAndImageName:(NSString *)imageName {
    
    UIView *view = [[UIView alloc] initWithFrame:CGRectZero];
    UIImageView *imageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:imageName]];
    imageView.frame = CGRectMake(kSectionX, kSectionY-20, kSectionWidth, kSectionHeight);
    [view addSubview:imageView];
    return view;
}

//返回每一组行数
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{
    
    if (!self.data) {
        return 0;
    }
    if(section == 1) {
        NSArray *nsarray_data=[self.data comic];
        return [nsarray_data count];
    }
    else if (section == 2) {
        NSArray *nsarray_data=[self.data animation];
        NSLog(@"hhhh%lu",(unsigned long)[nsarray_data count]);
        return [nsarray_data count];
    }

    return 0;

}

//通过indexPath 来设定每一行行高
-(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath{
    if (indexPath.section==1) {
        return 100;
    }
    else if(indexPath.section==2){
        return 100;}
    return 0;
}

//设置TableView中每一行显示的内容和格式的
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
    
        NSDictionary *cell_tableview_data;
        NSDictionary *cell_tableview_data_ani;
    
        if (indexPath.section==1) {


        HomepageViewcell *cell=[HomepageViewcell cellWithTableView:tableView];
            cell.delegate=self;
        NSArray *cell_data=[self.data comic];
        cell_tableview_data=[cell_data objectAtIndex:indexPath.row];
            //NSLog(@"%d",indexPath.row);
      
        cell.block_name=[cell_tableview_data video_name];
        cell.block_picture=[cell_tableview_data video_image];
        NSLog(@"%@",[cell_tableview_data video_intro]);
        cell.block_intro=[cell_tableview_data video_intro];
        cell.block_id=indexPath.row;
        cell.block_section=indexPath.section;
        return cell;
    } else if (indexPath.section==2)
    {
     HomepageViewcell *cell_ani=[HomepageViewcell cellWithTableView:tableView];
        cell_ani.delegate=self;

        NSArray *cell_data=[self.data animation];
        cell_tableview_data_ani=[cell_data objectAtIndex:indexPath.row];
            //NSLog(@"%d",indexPath.row);
    
        cell_ani.block_name=[cell_tableview_data_ani video_name];
        cell_ani.block_picture=[cell_tableview_data_ani video_image];
        NSLog(@"%@",[cell_tableview_data_ani video_intro]);
        cell_ani.block_intro=[cell_tableview_data_ani video_intro];
        cell_ani.block_id=indexPath.row;
        cell_ani.block_section=indexPath.section;
        return cell_ani;
    }
    return nil;
}


tableViewCell我自己写了一个HomepageViewcell

这是HomepageViewcell.xib


HomepageViewcell.h

我定义cell中block_name(名字);block_image(图片路径),block_intro(作品介绍),block_url(作品路径),

block_section(哪一个section) block_index(section中的第几个),并且声明要重定义一个方法,和一个代理协议

#import <UIKit/UIKit.h>

@protocol HomepageViewcellDelegate;

@interface HomepageViewcell : UITableViewCell
{
    __weak id<HomepageViewcellDelegate> _delegate;
}

@property(weak,nonatomic)id<HomepageViewcellDelegate>delegate;

@property(nonatomic,strong)NSString *block_name;
@property(nonatomic,strong)NSString *block_picture;
@property(nonatomic,strong)NSString *block_intro;
@property(nonatomic,assign)NSInteger block_section;
@property(nonatomic,assign)NSInteger block_index;
+(instancetype)cellWithTableView:(UITableView *)tableView;
@end

@protocol HomepageViewcellDelegate <NSObject>

@optional
-(void)didClickcomic:(HomepageViewcell *)view atindex:(NSInteger)index atsection:(NSInteger)section;

@end


HomapageViewcell.m这里就是实现重定义的方法,以及变量的赋值


#import "HomepageViewcell.h"
#import "AFNetworkTool.h"

@interface HomepageViewcell()
@property(nonatomic,weak)IBOutlet UIButton *icon;
@property(nonatomic,weak)IBOutlet UILabel *name;
@property(nonatomic,weak)IBOutlet UILabel *intro;
@end
@implementation HomepageViewcell

//实现重定义的方法
+(instancetype)cellWithTableView:(UITableView *)tableView
{
    static NSString *ID=@"HomepageViewCell";
    HomepageViewcell *cell=[tableView dequeueReusableCellWithIdentifier:ID];
    
    if (cell==nil) {
        cell=[[[NSBundle mainBundle]loadNibNamed:@"HomepageViewcell" owner:nil options:nil]lastObject];
        NSLog(@"xib");
    }
    return cell;
}

-(void)setBlock_name:(NSString *)block_name{
    self.name.text=block_name;
}
-(void)setBlock_picture:(NSString *)block_picture{
  NSString *image_url=block_picture;
  NSLog(@"%@",image_url);
  [AFNetworkTool imageRequestWithUrl:image_url success:^(UIImage *image_s)
   { [self.icon setImage:image_s forState:UIControlStateNormal]; } fail:^{
        NSLog(@"图片加载失败");
    }];
    
    [self.icon addTarget:self action:@selector(icon_button:) forControlEvents:UIControlEventTouchUpInside];
    
}

-(void)setBlock_intro:(NSString *)block_intro{
    self.intro.text=block_intro;
}

-(void)icon_button:(UIButton *)sender{
//    NSLog(@"icon_button:%d,%d",self.block_section,self.block_index);
//    if (!_delegate) {
//        NSLog(@"delegate is nil");
//    }
    if ([_delegate respondsToSelector:@selector(didClickcomic:atindex:atsection:)]) {
        NSLog(@"icon_button");
       [_delegate didClickcomic:self atindex:_block_index atsection:_block_section];
    }else{
        NSLog(@"fail");
    }
}
@end

最后讲一下我声明的代理协议

//tableViewCell动画or漫画的跳转
- (void)didClickcomic:(HomepageViewcell *)view atindex:(NSInteger)index atsection:(NSInteger)section
{
    NSDictionary *data;
    NSString *image_url;
    NSArray *comic_data;
    if (section==1) {
     if (comic_data==nil) {
            comic_data=[self.data comic];
        }
    data=[comic_data objectAtIndex:index];
    image_url=[data video_url];
        
    KxMovieViewController *comicVC = [KxMovieViewController movieViewControllerWithContentPath:image_url parameters:nil];
        
    [self.navigationController pushViewController:comicVC animated:YES];
    }
    else if (section==2){
        if (comic_data==nil) {
            comic_data=[self.data animation];
        }
        
        data=[comic_data objectAtIndex:index];
        
        scrollviewcontroller *animationVC=[[scrollviewcontroller alloc]init];
        animationVC.url=[data video_url];
        animationVC.num=[data page_num];
        [self.navigationController pushViewController:animationVC  animated:YES];
    }

}

不难看出来,每次我点击后,会判断是哪一个section是动画or漫画?然后初始化不同控制器,一个播发器控制器,一个图片浏览器控制器,接着把数据传递进去,然后让他们负责,我就不管了,至于视频播放控制器是采用第三方框架FFmpeg,图片播放器是根据我之前自己写的Scrollview图片循环播放改写,把循环给去掉了,并重新添加了一个阉割版的”SDwebimage“框架用来获取图片


下一篇 主要讲分类控制器,其实分类在设计的时候思考过很多方法,是在远程服务器上面分类数据,然后传送过来,还是将所有数据全部传到ios的sqlite数据库里,本地再进行筛选 http://blog.youkuaiyun.com/u012723810/article/details/50493045
