Block objects are a C-level syntactic and runtime feature.  The caret symbol (^) is used as a syntactic marker for blocks. They are similar to standard C functions, but in addition to executable code they may also contain variable bindings to automatic (stack) or managed (heap) memory. A block can therefore maintain a set of state (data) that it can use to impact behavior when executed. Blocks are objects that encapsulate a unit of work—or, in less abstract terms, a segment of code—that can be executed at any time. **blocks are function and can be pass as argument in function** They are essentially portable and anonymous functions that one can pass in as arguments of methods and functions or that can be returned from methods and functions. You may also assign a block to a variable and then call it just as you would a function. int (^Multiply)(int, int) = ^(int num1, int num2) { return num1 * num2; }; int result = Multiply(7, 4); // Result is 28. ...

Using this code we can make label and button , no need to write code again and again. //MakeLabel -( id ) makeLabelWithTag :( int ) tag andX :( CGFloat ) x Andy :( CGFloat ) y andWidth :( CGFloat ) width andHeight :( CGFloat ) height andText :( NSString *) Text andFontName :( NSString *) fontName andFontSize :( CGFloat ) fontSize andFontColor :( UIColor *) color { UILabel * label = [[ UILabel alloc ] initWithFrame : CGRectMake ( x , y , width , height )]; label . text = Text ; label . tag = tag ; label . backgroundColor = [ UIColor clearColor ]; label . textColor = color ; NSString * fontName2 = @ "verdana" ; label . font = [ UIFont fontWithName : fontName2 size : fontSize ]; [ self . view addSubview : label ]; return self ; } //Make Button -( id ) makeBtnWithTag :( int ) tag andX :( CGFloat ) x Andy :( CGFloat ) y andWidth :( CGFloat ) width andHeight :( CGFloat ) height andImageName :( NSS...

Make Label :- using this we can make label dynamically based on array value  categoryAry =[[ NSArray alloc ] initWithObjects : @"Object1" , @"Object2" , @"Object3" , @"Object4" , @"Object5" , @"Object6" , @"Object7" , @"Object8" , @"Object9" , @"Object10" , nil ]; -( void )mekeAllLabelDynamicly {     CGFloat startX= 50.0f ;     CGFloat startY= 150.0f ;     for ( int i = 0 ; i< [ categoryAry count ]; i++)     {         UILabel *label=[[ UILabel alloc ] init ];         label. text = [ categoryAry objectAtIndex :i];         label. tag =i;         label. textColor = [ UIColor whiteColor ];         label. backgroundColor =[ UIColor clearColor ];         CGRect frame= CGRectMake (startX, startY+( 31 + 10 )*i, 100 , 31 );         [label setFrame :frame]; ...
