ios 排序

ios 排序相关排序代码如下：

//冒泡排序
-(void)bubblesort {
    for (int i = 0; i < self.label.count-1; i++) {
        
        UILabel *labi = self.label[i];
        
        for (int j = i; j <self.label.count; j++) {
            
            UILabel *labj = self.label [j];
            
            if ([labi.text intValue] > [labj.text intValue]) {
                NSLog(@"");
            }
        }
    }
}

    //可变数组冒泡排序
    for (int i = 0; i < listArray.count; i++) {
        
        VideoList *videoi = (VideoList *)listArray[i];
        
        for (int j = i; j < listArray.count ; j++) {
            
            VideoList *videoj = (VideoList *)listArray[j];
            
            if ([videoi.sort intValue] < [videoj.sort intValue])
            {
                [listArray exchangeObjectAtIndex:i withObjectAtIndex:j];
            }
        }
    }

//系统自带排序
- (void)parseArray
{
    self.surArray = [self.array sortedArrayUsingComparator:^(id number1,id number2) {
        
        int val1 = [[number1 objectForKey:@"type"] intValue];
        
        int val2 = [[number2 objectForKey:@"type"] intValue];
        
        if (val1 > val2)
        {
            return NSOrderedDescending;
        }
        else
        {
            return NSOrderedAscending;
        }
    }];
}
