年后回来上了个新版本，主要是添加自动投标功能。因为工期紧，只是把功能实现了，没有考虑太多的结构优化。大部分的subview和逻辑都放在了vc里面，这样的恶果是出了问题，特别难定位，一团乱。故乘刚发完新版 新功能又还没确定间隙，初步把该功能vc优化了下。
效果图
大致思路
自定义cell（cell里面根据row不同，设置cell上不同的subview）；
vc将默认信息model传给自定义cell；
自定义cell将用户输入的信息回调给vc；
最后vc处理相应逻辑，请求后台接口。
涉及到的控件：textfield，pickview（集成开源三方），button互斥，uiswich等
ViewController(简称vc)核心代码
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
AutoInvesCustomCell *cell = [AutoInvesCustomCell cellWithTableView:tableView indexPath:indexPath];
cell.investInfo = investInfo;
cell.blockPick = ^(NSString *strResult, NSInteger row, AutoInvesCustomCell *cell) {
if (row == 1) {
strRate = strResult;
cell.lbRate.text = strResult;
}else{
strMonth = strResult;
cell.lbMonth.text = strResult;
}
};
cell.blockBidType = ^(NSInteger tag, BOOL isSelected) {
isBidQrb = ((tag == 101 && isSelected) ? YES:NO);
isBidXiny = ((tag == 102 && isSelected) ? YES:NO);
if (tag == 100 && isSelected) {
isBidQrb = YES;
isBidXiny = YES;
}
};
cell.blockAmount = ^(NSString *text) {
strAmount = text;
};
cell.blockAllAmount = ^(BOOL isOn) {
isRichMan = isOn;
//开启全投后 对tf的处理
NSIndexPath *indexPath = [NSIndexPath indexPathForRow:0 inSection:1];
AutoInvesCustomCell *tfCell = [tableView cellForRowAtIndexPath:indexPath];
tfCell.tfAmount.enabled = !isRichMan;
tfCell.tfAmount.text = isRichMan? @"全投":strAmount;
};
return cell;
}
自定义cell头文件(AutoInvesCustomCell.h)
#import <UIKit/UIKit.h>
#import "AutoInvestModel.h"
#define AddBottomLine(view) CGFloat lineHeight = 0.5f;\
CGRect lineFrame = CGRectMake(ContentX, HeightNormalCell-lineHeight, kScreenWidth-2*ContentX, lineHeight);\
UIView *lineNavBottom = [[UIView alloc] initWithFrame:lineFrame];\
lineNavBottom.backgroundColor = kColorLineSeperator;\
[view addSubview:lineNavBottom];
//宏定义
@class AutoInvesCustomCell;
typedef void(^BidTypeCellBlock)(NSInteger tag,BOOL isSelected);
typedef void(^AllAmountSWBlock)(BOOL isOn);
typedef void(^AmountTFBlock)(NSString *text);
typedef void(^PickViewBlock)(NSString *strResult,NSInteger row,AutoInvesCustomCell *cell);
@interface AutoInvesCustomCell : UITableViewCell
@property(strong,nonatomic)AutoInvestInfo *investInfo;

自定义cell 实现文件（因篇幅有限，只摘取了大概框架代码）
+ (instancetype)cellWithTableView:(UITableView *)tableView indexPath:(NSIndexPath*)indexPath{
static NSString *ID = @"cellID";
AutoInvesCustomCell *cell = [tableView dequeueReusableCellWithIdentifier:ID];
if(!cell)
{
cell = [[AutoInvesCustomCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:ID];
cell.selectionStyle = UITableViewCellSelectionStyleNone;
cell.currIndexPath = indexPath;
if (indexPath.section == 0) {
[cell setupBannerCell];
}
if (indexPath.section == 2) {
[cell setupAllCell];
}
if (indexPath.section == 1) {
switch (indexPath.row) {
case 0:
[cell setupAmount];
break;
case 1:
[cell setupRate];
break;
case 2:
[cell setupMonth];
break;
case 3:
[cell setupBidMode];
break;
default:
break;
}
}
}
return cell;

感想
简单封装优化之后，后期若需扩展，就比较容易：
若更新UI 直接修改cell文件；
若修改相应逻辑 直接修改vc即可等
这样结构相对也比较清晰。
值得记录的问题：
1 button互斥
思路：遍历所有的button，若不是当前所选button，让其selected为NO
2 全投状态 更新限定金额输入框text及enable状态
思路：在开关的回调中拿到 输入框cell，之后再对该cell上的tf做相应更新（[tb reload]是不行的）
不足处：
回调block太多;
cell不够明晰等
待后续更好的优化
后续：
其实后来想想这种static 不重用的cell ，封装一个带xib的tableview即可，没必要像上面那样自定义那么多cell
