iphone開發數組排序(數組中包括字典)  1。普通數組排序:     NSMutableArray *arr = [NSMutableArray arrayWithObjects:@"0",@"8",@"6",@"1",nil];     NSArray *sortedArray = [arr sortedArrayUsingComparator:^NSComparisonResult(id obj1, id obj2){if ([obj1 intValue] > [obj2 intValue]){return NSOrderedDescending;}if ([obj1 intValue] < [obj2 intValue]){return NSOrderedAscending;}return NSOrderedSame;}];      NSLog(@"排序後的數組:%@",sortedArray);2.數組中有字典的排序:    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];    [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(@"排序後的數組%@",myMutableArr);經驗證,上面的方式相當方便,尤其是數組中有字典的情況。
