If you use ARC you may happen to meet this warning message: "PerformSelector may cause a leak because its selector is unknown". In the first half of this article I will give some examples on how to avoid this warning by using some alternate methods, after that I will show other examples for performSelector alternatives on different situations.

If you are having multiple views in your application, and in that case you want to have a variable accessible to every view, you should always create a Model/Data(singleton) class and define the variable in it. Something like this :

//DataClass.h      

@interface DataClass:NSObject{

NSMutableArray *arrGlobal;

}

@property(nonatomic,retain) NSMutableArray *arrGlobal;

+(DataClass*)getInstance;

@end

//DataClass.m    

@implementation DataClass 

@synthesize arrGlobal;

static DataClass *instance =nil;

+(DataClass*)getInstance    
{

@synchronized(self){

if(instance==nil){    

   instance = [DataClass new];
}

}

return instance;

}

Now in your view controller you need to call this method as :

DataClass *obj= [DataClass getInstance];  
obj.arrGlobal = arrLocal;

This variable will be accessible to every view controller. You just have to create an instance of Data class.

UIView siblings are stacked in the order in which they are added to their superview. The UIViewhierarchy methods and properties are there to manage view order. In UIView.h:

@property(nonatomic,readonly)UIView*superview;

@property(nonatomic,readonly,copy)NSArray*subviews;

-(void)removeFromSuperview;

-(void)insertSubview:(UIView*)view atIndex:(NSInteger)index;

-(void)exchangeSubviewAtIndex:(NSInteger)index1 withSubviewAtIndex:(NSInteger)index2;

-(void)addSubview:(UIView*)view;

-(void)insertSubview:(UIView*)view belowSubview:(UIView*)siblingSubview;

-(void)insertSubview:(UIView*)view aboveSubview:(UIView*)siblingSubview;

-(void)bringSubviewToFront:(UIView*)view;

-(void)sendSubviewToBack:(UIView*)view;

The sibling views are ordered back to front in the subviews array. So the topmost view will be:

[parentView.subviews lastObject];

and bottom view will be:

[parentView.subviews objectAtIndex:0];

Like Kolin Krewinkel said, [parentView bringSubviewToFront:view] will bring the view to the top, but this is only the case if the views are all siblings in the hierarchy.

var query = invoiceList 
            .GroupBy(g => new { g.InvoiceDate, 
                                g.InvoiceType }) 
            .Select(group => new { 
                       InvoiceDate = group.Key.InvoiceDate, 
                       InvoiceType = group.Key.InvoiceType, 
                       TotalAmount = group.Sum(a=>a.InvoiceAmount), 
                       TotalCount = group.Sum(c=>c.NumberOfItems)});
