iOS 数组的排序——顺序倒序

NSArray *array = @[@1, @20, @3, @10, @2];

//排序后到新数组里

NSArray *sortedArray = [array sortedArrayUsingComparator:^NSComparisonResult(NSNumber* obj1, NSNumber* obj2) {

if ([obj1 intValue] > [obj2 intValue]) {

return NSOrderedDescending;

} else {

return NSOrderedAscending;

}

}];

NSLog(@"%@",sortedArray);
