--------------add a set of data to Bmob

Add a piece of data to Gamescore table with a score of playername of 78

Bmobobject *gamescore = [Bmobobject objectwithclassname:@ "Zhenshi"];

[Gamescore setobject:@ "true" forkey:@ "Wukun"];

[Gamescore setobject:@100 forkey:@ "ww"];

[Gamescore setobject:[nsnumber Numberwithbool:yes] forkey:@ "Cheatmode"];

[Gamescore saveinbackgroundwithresultblock:^ (BOOL issuccessful, Nserror *error) {

To operate

}];

-----------Find Data

Bmobquery *bquery = [bmobquery querywithclassname:@ "Gamescore"];

Finding data for Gamescore tables

[Bquery findobjectsinbackgroundwithblock:^ (Nsarray *array, Nserror *error) {

For (Bmobobject *obj in array) {

Print PlayerName

NSLog (@ "obj.playername =%@", [obj objectforkey:@ "playername"]);

Print Objectid,createdat,updatedat

NSLog (@ "Obj.objectid =%@", [obj objectId]);

NSLog (@ "Obj.createdat =%@", [obj Createdat]);

NSLog (@ "Obj.updatedat =%@", [obj Updatedat]);

}

}];

It is important to note that:

1. By default, the system does not actually return all the data, but instead returns 10 data records by default, and you can set the number of records returned by the Setlimit method. For more details, click to view the section on paging queries.

2. When querying a system table of the user table, the return is an array of bmobuser, a device table, and a role table.

3. Query the user table, the device table, the role table is:

Bmobquery *bquery = [bmobuser query]; User table

Bmobquery *bquery = [bmobinstallation query]; Equipment table

Bmobquery *bquery = [bmobrole query]; Role table
