需求如下：
屏幕快照 2018-09-18 下午4.29.18.png
该列表中第一行和第二行的数据是不可以删除的，第三行数据支持删除功能，最后一行数据未新增一行数据的功能。
思路：
看到这个设计，第一想到的就是用UITableView来处理再正常不过了。
其次，常见故障维修、突发故障维修为固定的内容，所以我将这块划定为一种cell样式,新增维修类型同这两个不一样，右边有一个删除按钮的功能,所以我将这块定义为另外一种cell样式.至于最底部+新增维修类型的按钮事件显示，我把它定义为UITableView的tableFooterView。
具体实现如下：
每个VC还是老样子的创建方式
@interface SCChooseMaintenanceTypesVC ()<UITableViewDelegate,UITableViewDataSource>
@property (nonatomic, strong) UITableView *tableView;
@property (nonatomic, strong) UIButton *addRowBtn;
@property (nonatomic, strong) SCMaintenanceInteractor *interactor;//数据 这个会在项目架构中介绍此用法
@end
@implementation SCChooseMaintenanceTypesVC
- (void)viewWillAppear:(BOOL)animated{
[super viewWillAppear:animated];
}
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view.
[self setNavItem];
[self addSubViews];
[self setConstraints];
[self initParams];
[self reloadData];
}
- (void)setNavItem{
self.isNewNavigationBarStyle = YES;
self.title = @"新增维修类型";
}
- (void)addSubViews{
[self.view addSubview:self.tableView];
self.addRowBtn.hidden = YES;
self.tableView.tableFooterView = self.addRowBtn;
}
- (void)setConstraints{
[self.tableView mas_makeConstraints:^(MASConstraintMaker *make) {
make.top.mas_equalTo(self.view).mas_offset(13);
make.leading.trailing.mas_equalTo(self.view);
if (@available(iOS 11.0, *)) {
make.bottom.mas_equalTo(self.view.mas_safeAreaLayoutGuideBottom);
} else {
make.bottom.mas_equalTo(self.view.mas_bottom);
}
}];
}
- (void)reloadData{
@Weakify(self)
[SQProgressHUD showLoding];
[self.interactor getAllMaintenanceTypeList:^{
@Strongify(self)
self.addRowBtn.hidden = NO;
[self.tableView reloadData];
[SQProgressHUD hideLoding];
} Failure:^{
[SQProgressHUD hideLoding];
}];
}
创建TabelViewCell
#pragma mark --UITableViewDelegate
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{
return self.interactor.dataArrayM.count;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
SCRepairTypeModel *typeModel = [self.interactor.dataArrayM objectAtIndex:indexPath.row];
if (indexPath.row == 0 || indexPath.row == 1) {
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"UITableViewCell"];
cell.backgroundColor = [UIColor whiteColor];
UILabel *textLabel = [[UILabel alloc] initWithFrame:CGRectMake(15, 18, 140, 24)];
textLabel.textColor = [UIColor SCTextBlackColor];
textLabel.font = [UIFont sysFont16];
textLabel.text = typeModel.name;
[cell addSubview:textLabel];
UILabel *rightLabel = [[UILabel alloc] initWithFrame:CGRectMake(kSCREEN_WIDTH-114-15, 18, 120, 24)];
rightLabel.textColor = [UIColor SCTextLightGrayColor];
rightLabel.font = [UIFont sysFont14];
rightLabel.text = @"(默认不可删除)";
[cell addSubview:rightLabel];
UIView *line = [[UIView alloc] initWithFrame:CGRectMake(15, 58, kSCREEN_WIDTH-30, 2)];
line.backgroundColor = [UIColor SCTableSeparateColor];
[cell addSubview:line];
cell.selectionStyle = UITableViewCellSelectionStyleNone;
return cell;
}else{
__weak typeof(self) weakSelf = self;
SCEMTypesCell *cell = [tableView dequeueReusableCellWithIdentifier:@"SCEMTypesCell"];
cell.selectionStyle = UITableViewCellSelectionStyleNone;
[cell setCellWithModel:typeModel];
cell.deleteBtnClick = ^{
[self.interactor deleteDeviceRepairWithTypeID:typeModel.device_repair_type_id Success:^{
if (weakSelf.update) {
weakSelf.update();
}
[weakSelf.tableView reloadData];
} Failure:nil];
};
return cell;
}
return nil;
}
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath{
return 60;
}
懒加载
#pragma mark 懒加载
-(UITableView *)tableView{
if (!_tableView) {
_tableView = [[UITableView alloc]initWithFrame:CGRectZero style:UITableViewStylePlain];
[_tableView registerClass:[UITableViewCell class] forCellReuseIdentifier:@"UITableViewCell"];
[_tableView registerClass:[SCEMTypesCell class] forCellReuseIdentifier:@"SCEMTypesCell"];
_tableView.separatorStyle = UITableViewCellSeparatorStyleNone;
_tableView.backgroundColor = [UIColor SCBackGroundColor];
_tableView.dataSource = self;
_tableView.delegate = self;
if (@available(iOS 11.0, *)) {
_tableView.contentInsetAdjustmentBehavior = UIScrollViewContentInsetAdjustmentNever;
} else {
self.automaticallyAdjustsScrollViewInsets = NO;
}
}
return _tableView;
}
- (UIButton *)addRowBtn{
if (!_addRowBtn) {
_addRowBtn = [UIButton buttonWithType:UIButtonTypeCustom];
_addRowBtn.frame = CGRectMake(0, 0, kSCREEN_WIDTH, 60);
_addRowBtn.titleLabel.font = [UIFont fontWithName:@"iconfont" size:16];
[_addRowBtn setTitleColor:[UIColor SCTextBlueColor] forState:UIControlStateNormal];
[_addRowBtn setTitle:@"\ue643 新增维修类型" forState:UIControlStateNormal];
[_addRowBtn setTitleColor:[UIColor SCTextBlueColor] forState:UIControlStateNormal];
[_addRowBtn setBackgroundColor:[UIColor whiteColor]];
@Weakify(self)
[_addRowBtn handleControlEvent:UIControlEventTouchUpInside withBlock:^{
@Strongify(self)
SCMaintenanceTypeInputVC *inputVC = [[SCMaintenanceTypeInputVC alloc] init];
inputVC.scPageConfigKey = @"DEVICE/DETAIL/SERVICE/CATEGORY/INDEX";
inputVC.appKey = @"FMP";
inputVC.areaId = self.areaId?:[[SCBUUserDefaultsManager shareUserDefaultsManager] getDataByKey:FacilityRepairRecordSelectAreaIdKey];
[self goVC:inputVC];
inputVC.model = ^(SCRepairTypeModel *model) {
[self.interactor.dataArrayM addObject:model];
NSIndexPath *indexPath = [NSIndexPath indexPathForRow:self.interactor.dataArrayM.count-1 inSection:0];
[_tableView insertRowsAtIndexPaths:@[indexPath] withRowAnimation:UITableViewRowAnimationAutomatic];
if (self.update) {
self.update();
}
};
}];
}
return _addRowBtn;
}
- (SCMaintenanceInteractor *)interactor{
return _interactor = _interactor?:[[SCMaintenanceInteractor alloc] init];
}
@end
其中addRowBtn事件中完成了insertRowsAtIndexPaths在UITabelView中插入一条数据的功能。
inputVC.model = ^(SCRepairTypeModel *model) {
[self.interactor.dataArrayM addObject:model];
NSIndexPath *indexPath = [NSIndexPath indexPathForRow:self.interactor.dataArrayM.count-1 inSection:0];
[_tableView insertRowsAtIndexPaths:@[indexPath] withRowAnimation:UITableViewRowAnimationAutomatic];
if (self.update) {
self.update();
}
};
点击删除按钮完成的事件通过deleteBtnClickBlock完成deleteDeviceRepairWithTypeID来实现
cell.deleteBtnClick = ^{
[self.interactor deleteDeviceRepairWithTypeID:typeModel.device_repair_type_id Success:^{
if (weakSelf.update) {
weakSelf.update();
}
[weakSelf.tableView reloadData];
} Failure:nil];
};
以上是针对列表中新增、删除某一行数据的具体实现。
