objective-c - 配列とオブジェクトの並べ替え

Question

配列内のこれらの値を逆順に並べるにはどうすればよいですか?

_gradientArrayToWhite = [[NSArray alloc] initWithObjects:@"1", @"2", @"3", @"4", @"5", @"6", @"7", @"8", @"9", @"10", nil];

Answer 1

NSArray *arr = [NSArray arrayWithObjects:[NSNumber numberWithInt:1],[NSNumber numberWithInt:2],[NSNumber numberWithInt:3],[NSNumber numberWithInt:4],[NSNumber numberWithInt:5],[NSNumber numberWithInt:6],[NSNumber numberWithInt:7],[NSNumber numberWithInt:8],[NSNumber numberWithInt:9],[NSNumber numberWithInt:10], nil];

ここで、このように配列を直接使用することもできます

NSArray *arr1 = [[NSArray alloc] initWithObjects:@"1", @"2", @"3", @"4", @"5", @"6", @"7", @"8", @"9", @"10", nil];


NSArray *revArr = [[arr reverseObjectEnumerator] allObjects];

Result = <__NSArrayM 0x71348e0>(
 10,
 9,
 8,
 7,
 6,
 5,
 4,
 3,
 2,
