iOS 对于服务器下发数据的判断

{

data = (

{

id = “”;

pCode = “”;

properties = {

charge = {

align = “”;

bold = “”;

color = blue;

content = “1,305,140”;

dataIndex = “”;

flex = “”;

getClass = “”;

hidden = “”;

iconCls = “”;

id = “”;

locked = “”;

tooltip = “”;

width = “”;

xtype = “”;

};

1> 针对 字段值为: “”

[_model.属性 isKindOfClass:[NSNull class]];

2> 针对字段值为: “ ”

[_model.属性 isEqualToString:@”“];
