列表.gif
背景:列表中有很多数据，每个数据都对应一个点击事件。
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath;方法会非常的长，导入的头文件也非常多。想交换两个位置，会非常困难。

直接使用tableView,缺点非常明显，viewController类非常臃肿，而且多个的列表，需要重复写tableView的方法。我想到使用json来配置tableView的数据源和跳转的类及方法参数。
封装之后的viewController没有一行代码,继承自BaseSectionTableViewViewController加一个json配置文件。这样我想增加一个列表或交换列表的顺序也非常简单。
#import <UIKit/UIKit.h>
#import "BaseSectionTableViewViewController.h"
NS_ASSUME_NONNULL_BEGIN
@interface CoreAnimationViewController : BaseSectionTableViewViewController
@end
NS_ASSUME_NONNULL_END
#import "CoreAnimationViewController.h"
@interface CoreAnimationViewController ()
@end
@implementation CoreAnimationViewController
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view.
[self setTitle:@"动画"];
}
@end
viewController实现.png
BaseSectionTableViewViewController的实现:
1.通过类名读取对应的配置文件，我把解析的方法放在NSObject(Json)中:
- (id)readConfigJsonWithName:(NSString *)name{
NSString *path = [[NSBundle mainBundle] pathForResource:name ofType:@"json"];
if (!path) {
return nil;
}
NSData *data = [NSData dataWithContentsOfFile:path];
id dataId = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:nil];
return dataId;
}
2.解析配置文件信息
2.1 json配置介绍
title是用于展示titleForHeaderInSection的NSString，是一个数组。
content节点可配置title、classname、storyboardname、method、params。
{
"title":[
"其他",
"小知识点总结"
],
"content":[
[
{
"title":"UIScrollView嵌套tableView",
},
{
"title":"点赞动画",
},
{
"title":"排行榜C化",
"classname":"ClassifyViewController",
"storyboardname":"CMClassify"
},
{
"title":"壹句",
"classname":"CMMiguOneSentenceViewController"
},
{
"title":"图片裁剪",
"classname":"ClipImageViewController"
},
{
"title":"轮播图ScrollView",
"classname":"SlideshowScrollViewController"
},
{
"title":"彩虹",
"classname":"RainbowViewController"
},
{
"title":"NSString 为什么用copy",
"classname":"CopyNString",
"method":"main"
},
{
"title":"关联对象弹窗",
"classname":"AssociatedAlertView",
"method":"askUserAQuestion"
},
{
"title":"虚拟定位",
"classname":"SelectLocationViewController"
},
{
"title":"微信步数模拟",
"classname":"WeChatStepSimulation",
"method":"main"
},
{
"title":"动画按顺序执行",
"classname":"SequenceAnimationViewController"
},
{
"title":"UIWebView",
"classname":"UIWebViewViewController"
},
{
"title":"WKWebView",
"classname":"WKWebViewViewController"
},
{
"title":"xib引用xib使用",
"classname":"UseXibViewController"
},
{
"title":"UILable内边距设置",
"classname":"LabelEdgeInsetViewController"
},
{
"title":"网络请求",
"classname":"NetworkViewController"
}
],
[
{
"title":"多线程",
"classname":"ThreadProblemViewController"
},
{
"title":"内存泄露",
"classname":"MemoryLeakViewController"
},
{
"title":"RunLoop",
"classname":"RunLoopViewController"
},
{
"title":"RunTime",
"classname":"RuntimeViewController"
},
{
"title":"Category",
"classname":"CategoryViewController"
},
]
]
}
2.2获取title
- (NSString *)getTitleFromSectionTableView:(NSIndexPath *)indexPath{
id content = self.contentArray[indexPath.section][indexPath.row];
if ([content isKindOfClass:[NSDictionary class]]) {
NSDictionary * contentDict = (NSDictionary *)content;
return contentDict[BASETABLEVIEW_CONTENT_TITLE];
}else if([content isKindOfClass:[NSString class]]){
return content;
}
return nil;
}
title分两种，如果是NSString直接展示，如果是NSDictonary,则取出其中的title。
2.3 处理点击事件
2.3.1考虑到UIViewController可能是xib、纯代码、或storyBoard创建。如果是UIViewController类直接push。
id content = self.contentArray[indexPath.section][indexPath.row];
NSString * className;
NSString * storyBoardName;
if ([content isKindOfClass:[NSString class]]) {
className = (NSString *)content;
}else{
NSDictionary * contentDict = (NSDictionary *)content;
className = contentDict[BASETABLEVIEW_CONTENT_CLASSNAME];
storyBoardName = contentDict[BASETABLEVIEW_CONTENT_STORYBOARDNAME];
_params = contentDict[BASETABLEVIEW_CONTENT_PARAMS];
_method = contentDict[BASETABLEVIEW_CONTENT_METHOD];
}
id objClass = nil;
if (storyBoardName && storyBoardName.length>0) {
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:storyBoardName bundle:[NSBundle mainBundle]];
objClass = [storyboard instantiateViewControllerWithIdentifier:className];
}else{
objClass = [NSClassFromString(className) new];
}
if (!objClass) {//对象是空直接return
return;
}
2.3.2 params解析
NSObject (AddParams)来给NSObject动态添加参数
- (void)setParams:(NSDictionary *)params {
objc_setAssociatedObject(self, @"params", params, OBJC_ASSOCIATION_RETAIN_NONATOMIC);
}
- (NSDictionary *)params {
return objc_getAssociatedObject(self, @"params");
}
2.3.3 method解析
SEL selector = NSSelectorFromString(_method);
if ([objClass respondsToSelector:selector]) {
[objClass performSelector:selector withObject:self.params];
}
3.使用:
3.1可通过pod方式集成
3.2新建viewController继承BaseSectionTableViewViewController,并新建一个json文件。
{
"title":"标题",
"classname":"ViewController",
"storyboardname":"storyboard名称，可省略",
"params":{
"type":"0"
}
}
3.3 配置
3.3.1 仅展示title
{
"title":"点赞动画",
}
3.3.2 纯代码创建
{
"title":"图片裁剪",
"classname":"ClipImageViewController"
}
3.3.3 storyboard创建
{
"title":"排行榜C化",
"classname":"ClassifyViewController",
"storyboardname":"CMClassify"
}
3.3.4 创建NSObject并运行指定方法
{
"title":"NSString 为什么用copy",
"classname":"CopyNString",
"method":"main"
}
3.3.5 创建类并带有参数
{
"title":"CGAffineTransform 仿射变换",
"classname":"AffineTransformViewController",
"storyboardname":"CoreAnimationStoryboard",
"params":{
"type":"0"
}
}
总结:
这种方式使得viewController类非常整洁，新增一个列表非常方便。不用关心跳转了，由BaseTableViewViewController为我们做好。
具体使用可参考 demo
