Swift版國内省市縣三級關聯

1、引入資料模型 CountryCityModel.swift

如下檔案為省市縣最新資料Model,使用的struct 結構體處理，比類的記憶體占用更小：

            pickerView.reloadComponent(1)

            //更新縣
            CountryCityModel.current_city = CountryCityModel.City[pickerView.selectedRow(inComponent: 1)]
            pickerView.reloadComponent(2)
            
            if list_cell_count > 2 {
                index = pickerView.selectedRow(inComponent: 2)
                if CountryCityModel.County.count < index {index = 0}
                
                CountryCityModel.current_county = CountryCityModel.County[index]
            }
        }
        //市
        else if component == 1 && row < CountryCityModel.City.count {
            let index = pickerView.selectedRow(inComponent: 1)
            CountryCityModel.current_city = CountryCityModel.City[index]
            
            //更新縣
            if list_cell_count > 2 {
                pickerView.reloadComponent(2)
            }
        }
        //縣
        else if component == 2 && row < CountryCityModel.County.count {
            let index = pickerView.selectedRow(inComponent: 2)
            CountryCityModel.current_county = CountryCityModel.County[index]
        }
    }
}
           

3、在需要的地方調用 showAddressBox 方法(支援Obj-C)

具體使用參考如下：

//位址選擇
@property(nonatomic,strong) AddressBoxView *addressBoxView;

-(AddressBoxView *)addressBoxView{
    if (!_addressBoxView) {
        CGFloat h = K_APP_CUSTOM_BOX_HEIGHT;
        CGFloat y = K_APP_HEIGHT - h;
        if ([[UIDevice currentDevice] isiPhoneX]) {
            y -= K_APP_IPHONEX_BUTTOM;
        }
        
        CGRect rect = CGRectMake(0, y, K_APP_WIDTH, h);
        _addressBoxView = [[AddressBoxView alloc] initWithFrame:rect];
        _addressBoxView.delegate = self;
    }
    
    return _addressBoxView;
}

/**
 * 顯示位址選擇
 * @param strOldValue String 已經選中的位址,不存在可為nil(省市縣資料使用的 空格分割)
 * 在需要顯示位址的地方調用此方法即可
 */ 
-(void)showAddressBox:(NSString *)strOldValue{
    if (strOldValue && ![strOldValue isEqualToString:@""]) {
        NSCharacterSet *charSet = [NSCharacterSet characterSetWithCharactersInString:@" "];
        NSArray *attTemp = [strOldValue componentsSeparatedByCharactersInSet:charSet];
        
        if (attTemp && [attTemp count] >= 2) {
            self.addressBoxView.province = [NSString stringWithFormat:@"%@",attTemp.firstObject];
            self.addressBoxView.city = [NSString stringWithFormat:@"%@",attTemp[1]];
            
            if ([attTemp count] >= 3) {
                self.addressBoxView.county = [NSString stringWithFormat:@"%@",attTemp.lastObject];
            }
            else{
                self.addressBoxView.county = @"";
            }
            
            [self.addressBoxView reloadWithIsConstraint:NO];
        }
    }
    else{
        [self.addressBoxView reloadWithIsConstraint:YES];
    }
    
    [self showListBox:self.addressBoxView];
}

/**
 * 該方法為附加方法，開源的自定義彈框元件
 * 具體使用參考：https://github.com/snail-z/zhPopupController.git
 */
-(void)showListBox:(UIView *)view{
    [self.zh_popupController setLayoutType:zhPopupLayoutTypeBottom];
    [self.zh_popupController setAllowPan:YES];
    [self.zh_popupController presentContentView:view];
}
           

4、通過實作 AddressBoxViewDelegate 可以關閉彈框 和 擷取 目前選中的位址資訊

以上資訊就是這些并附上效果圖，如有高見歡迎留言讨論
