Array sorting (by a key value pair in the dictionary in the array)

1. Normal array Ordering:

     nsmutablearray *arr = [Nsmutablearray arraywithobjects:@ "0", @ "8", @ "6", @ "1",nil];     nsarray *sortedarray = [arr sortedarrayusingcomparator:^nscomparisonresult (ID obj1, id obj2) {if ([Obj1 Intvalue] & Gt [Obj2 Intvalue]) {return nsordereddescending;} if ([Obj1 intvalue] < [obj2 Intvalue]) {return nsorderedascending;} return nsorderedsame;}];       NSLog (@ "sorted array:%@", Sortedarray),  2. The sort of dictionary in the array:    Nsmutablearray *mymutablearr = [[ [Nsmutablearray alloc] init] autorelease];    nsdictionary *dicone = [nsdictionary dictionarywithobjectsandkeys:@ "1", @ "price", @ "2", @ "number", nil];    nsdictionary *dictwo = [nsdictionary dictionarywithobjectsandkeys:@ "6", @ "price", @ "5", @ "number", nil];    nsdictionary *dicthree = [nsdictionary dictionarywithobjectsandkeys:@ "3", @ "price", @ "1", @ "number", nil];    nsdictionary *dicfour = [nsdictionary dictionarywithobjectsandkeys:@ "4", @ "price", @ "3", @ "number", nil];&nbsp   [Mymutablearr addobject:dicone];    [Mymutablearr addobject:dictwo];    [Mymutablearr addobject:dicthree];    [Mymutablearr addobject:dicfour];        Nsarray * Sortdescriptors = [Nsarray arraywithobject:[nssortdescriptor sortdescriptorwithkey:@ "Price" ascending:YES]];    [Mymutablearr sortusingdescriptors:sortdescriptors];    NSLog (@ "sorted array%@", Mymutablearr);
