How modal Views (Modaltrasitionstyle) fit into different versions

as the version is updated, the modal view also has different requirements for the version, so how to adapt the modal view to the requirements of multiple versions? here is a small series of personal views!

-(void) PRESENTMODALVC

{

Modalviewcontroller *modalvc= [[Modalviewcontroller alloc]init];

Modalvc.modaltransitionstyle = uimodaltrasitionstylecoververtical;//This is the style that sets the modal view

if ([[Uidevice currentdevice].systemversion floatvalue]<6.0)

{

[Self PRESENTMODALVIEWCONTROLLER:MODALVC animated:yes]; Wait for modification

}else{

[Self PRESENTVIEWCONTROLLER:MODALVC Animate:yes

Completion: ^{ NSLog(@ "mode back");}];

}

[MODALVC release];

}
