ios - how to release uibuttons object in for loop? -

i looping uibuttons object in loop count , when have release object , unfortunately supposed work non-arc application

this code have done

for (uibutton *btn in [self.locationscrollview subviews]) { if ([btn tag]==1) [btn setbackgroundimage:[uiimage imagenamed:@"whiteleft.png"] forstate:uicontrolstatenormal]; else if ([btn tag]==8) [btn setbackgroundimage:[uiimage imagenamed:@"whiteright.png"] forstate:uicontrolstatenormal]; else [btn setbackgroundimage:[uiimage imagenamed:@"whitemid.png"] forstate:uicontrolstatenormal]; }

no need release object unless creating it. here btn pointer button object. not release it.

[self.locationscrollview subviews]

returns array of sub views (may buttons). performing fast enumeration on array.

ios objective-c arrays for-loop uibutton
