首先我們要知道，這使用的是運行時的反射機制

所以我們需要標頭檔 runtime.h

+(BOOL)checkoutOneTabByName:(NSString*)oneName{    //openDB    FMDatabase *db = [DatabaseOperation openDataBase];        NSArray *array = [DatabaseOperation queryTable:oneName QueryString:[NSString stringWithFormat:@"select * from %@",oneName] DB:db];        for (id oneData in array) {                unsigned int propertyCount =0;                objc_property_t *FPAddress =class_copyPropertyList([oneData class], &propertyCount);                for (int i =0; i<propertyCount; i++) {                        objc_property_t *aProp =FPAddress+i;                        NSString *aName =[NSString stringWithUTF8String:property_getName(*aProp)];                        NSObject *aValue =[oneData valueForKey:aName];                        NSLog(@"%@,,,%@",aName,aValue);        }        NSLog(@"( * ^ __ * ^ ) %@ part print success",[oneData class]);    }        //關閉資料庫    [DatabaseOperation closeDataBase:db];        return YES;}
