2021-11-16 iOS实现对接口数据的搜索过滤

需求：实现根据搜索内容 展示在TableView上，搜索之前或者搜索文本为空则直接展示接口数据

(UITextfield/UITableView)

  pod'NSPredicateSearch', '~> 0.1.2'

ViewController.m中：

#import "NSPredicateSearch/NSPredicate+Search.h"

@property (nonatomic, strong)NSMutableArray *mulArray;                                      @property (nonatomic, strong)NSMutableArray *temArray;

自定义UITextfield初始化包括：

```

1： [self.header.searchTf addTarget:self action:@selector(textFieldDidChanged:) forControlEvents:UIControlEventEditingChanged];

```

3:事件方法 和其中的优化处理

- (void)textFieldDidChanged:(UITextField *)textField {//此判断不能放在textfield的shouldChangeCharactersInRange协议方法中                                                        UITextRange *markedTextRange = textField.markedTextRange;                                             //如果存在待选文字记录，则暂不处理 markedTextRange == nil说明不存在待选文字        if (markedTextRange == nil) {                                                                                            [self selectBankList];    }}

    -(void)selectBankList{                                                                                                             //刷新表格                                                                                                                                if (self.header.searchTf.text.length == 0) {                                                                self.mulArray =self.temArray;                                                                   [self.searchTabView reloadData];                                                                                                    return;    }                                                                                                                    // 重要                                                                                                            NSPredicate *predicate = [NSPredicate predicateWithSearch:self.header.searchTf.text searchTerm:@"searchTerms"];      self.mulArray = [[NSMutableArray alloc] initWithArray:[self.temArray filteredArrayUsingPredicate:predicate]];                                                            [self.searchTabView reloadData];}

SearchTypeModel.h

// 筛选标识 (根据这个标识，可直接对下面两个属性做过滤搜索                              @property (strong, nonatomic) NSString* searchTerms;

@property (nonatomic, copy) NSString *ExchangeCode;                                            @property (nonatomic, copy) NSString *ExchangeName; 

SearchTypeModel.m                                                                                                          (NSString *)searchTerms {    return [NSString stringWithFormat:@"%@ %@ %@",self.ExchangeCode, self.ExchangeName];}

通过接口获取字典数组数据，以Model取；接口数据：数组字典参考

(lldb) po response

{

    code = 0;

    data =    (

                {

            ExchangeCode = APEX;

            ExchangeName = "Asia Pacific Exchange";

            OmnibusSupport = 0;

        },

                {

            ExchangeCode = BMD;

            ExchangeName = "Bursa Malaysia Derivatives Berhad";

            OmnibusSupport = 0;

        },

                {

            ExchangeCode = IFUS;

            ExchangeName = "ICE Futures U.S.";

            OmnibusSupport = 0;

        },

                {

            ExchangeCode = INE;

            ExchangeName = "Shanghai International Energy Exchange";

            OmnibusSupport = 0;

                {

            ExchangeName = "Osaka Stock Exchange";

            OmnibusSupport = 0;

                {

            ExchangeName = "Singapore Exchange";

            OmnibusSupport = 0;

                {

        },

                {
