在这里插入图片描述

I 实现

1.1 加载数据

先请求接口获取数据。如果获取失败，就先从本地文件address_CRM获取数据


-(instancetype)initWithFrame:(CGRect)frame
{
    self = [super initWithFrame:frame];
    if (self)
    {//
        
        self.provinces = [QCTAreaListTool shareQCTAreaListTool].AreaList4CRM;// 先请求接口获取数据。如果获取失败，就先从本地文件address_CRM获取数据
        
        _nameStr = @"areaName";
        _cityStr = @"childNode";
        
                if (self.provinces.count == 0) {
                    
                    
                    
                    
                    NSString *addressPath = [[NSBundle mainBundle] pathForResource:@"address_CRM" ofType:@"plist"];
                    self.provinces = [[NSArray alloc]initWithContentsOfFile:addressPath];
                    
                    
        //            self.provinces = dict[@"address"];
        //            _nameStr = @"name";
        //            _cityStr = @"sub";
                    
                    
                    
                }
//
        
        
        
        
        
        
        self.provinceSelectIndex = -1;
        self.citySelectIndex = -1;
        self.areaSelectIndex = -1;
        [self setupChildViews];
    }
    return self;
}
