Groups seeking new ios is how to reference the control object

For example, an object can be obtained android control by findViewById way. In ios, I did not see a similar approach. Information pitiful. Seek expert explain.

Understand correctly, you want to get a child object controls, child controls.
To initiate the code, but also look TELL

 
- (UIView *) findView: (UIView *) aView withName: (NSString *) name {
Class cl = [aView class]; 
NSString * desc = [cl description]; 
if ([name isEqualToString: desc]) 
return aView; 
for (NSUInteger i = 0; i <[aView.subviewscount]; i + +) 
{
UIView * subView = [aView.subviewsobjectAtIndex: i]; 
subView = [selffindView: subView withName: name]; 
if (subView) 
return subView; 
} 
return nil; 
}
