Parse.com atomic safe approach to create PFObjects from iOS? -

-

Logged in PFUser is able to create an object with the square name "X" from an iOS app.

X is a name attribute and the only one X object can be.

The Any user on iOS can create an X object providing name for it.

That's why I am trying to ensure that only to ensure that an X is made with a "name" in the case of a group of users at the same time that the server Trying to create an object at.

So how can I guarantee only one object X is created on my parse.com system in a situation where a bunch of users tries to make the same object from the iOS client?

Thanks

Edit: I'm not controlling any cloud code. I want to know that this is only possible using the iOS code.

Thanks

EDIT 2: So, if this is not possible with iOS, how can I use this cloud code, do I have to solve this problem in cloudcod Can anyone give a quick introduction to?

Powerbuilder 12.1 and DataWindow in Design vs Debug and Executable/Runtime -

-
I have a very strange situation with Powerbuilder 12.1. I have two issues that can be related - mainly because this is the exact same data window report. Problem # 1: You can not see the contents of Detavindo any and went nowhere, lost the ability to debug and display content Detavindo at runtime during the debug and runtime. But when you go into the data window in design mode, it prompts for the values ​​of those parameters, the content is only displayed, it is okay. Edit: Solve. This is due to a powerbiller that uses an integer rather than a long variable. The identity identifier in the database exceeds the upper limit of a PowerBuilder 16-bit integer (32767). I updated the logic for longer use, and resolved this problem # 1. ISSUE # 2: When I run the report code using the same data window mentioned in issue # 1 above, in debug mode, to create a new report file, this work Done - only in DEBUG mode Runtime failure - I got an error -1 during the runtime for the exact same...
