将NSInteger添加到NSMutableArray

Question

我加载我的数组NSDocumentDirectory:

self.images = [NSMutableArray new];  
for(int i = 0; i <= 100; i++) 
{ 
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDir = [paths objectAtIndex:0];

    NSString *savedImagePath = [documentsDir stringByAppendingPathComponent:[NSString stringWithFormat:@"oneSlotImages%d.png", i]]; 
    NSLog(@"savedImagePath=%@",savedImagePath);
    if([[NSFileManager defaultManager] fileExistsAtPath:savedImagePath]){ 
        [images addObject:[UIImage imageWithContentsOfFile:savedImagePath]]; 

        NSLog(@"file exists");
    } 
    NSLog(@"file does not exist");
} 

NSLog(@"Count : %d", [images count]);  

这是我实现我的数组的地方:

- (UIView *)carousel:(iCarousel *)_carousel viewForItemAtIndex:(NSUInteger)index reusingView:(UIView *)view
{

    view = [[UIImageView alloc] initWithImage:[images objectAtIndex:index]];
    return view;

}

我在NSInteger上面添加了上面的数组viewDidLoad:

for (int x=0; x<+100;x++) {
        // add as NSString
        [images addObject:[NSString stringWithFormat:@"%d", x]];
        // add as NSNumber
        //[images addObject:[NSNumber numberWithInt:x]];
}

我无法添加NSInteger.如何添加NSInteger到NSMutableArray？

我遇到了崩溃:

使用NSNumber:

[yourMutableArray addObject:[NSNumber numberWithInt:yourIntValue]];
