Salesforce中判断对象中是否存在某字段

ApexCode示例

List<String> objectApiNameList = new List<String>(); // 传你想判断的对象
objectApiNameList.add('Account');

Schema.DescribeSobjectResult[] results  = Schema.describeSObjects(apiNames);

for(Schema.DescribeSobjectResult describeResult  : results){   
    System.debug(LoggingLevel.INFO, '*** 存在？: ' +
    describeResult.fields.getMap().keySet().contains('phone'));
}

获取全部对象

Map<String, Schema.SObjectType> globalDescribe = Schema.getGlobalDescribe(); 

System.debug(LoggingLevel.INFO, '*** globalDescribe: ' + globalDescribe);

for(string objectApi: globalDescribe.keyset()){    
    // YOUR CODE
}
