林加載我的陣列中的NSDocumentDirectory
:添加NSInteger的到一個NSMutableArray
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]);
這裏就是我實現我的數組:
- (UIView *)carousel:(iCarousel *)_carousel viewForItemAtIndex:(NSUInteger)index reusingView:(UIView *)view
{
view = [[UIImageView alloc] initWithImage:[images objectAtIndex:index]];
return view;
}
我與數組中的viewDidLoad
添加NSInteger
以上:
for (int x=0; x<+100;x++) {
// add as NSString
[images addObject:[NSString stringWithFormat:@"%d", x]];
// add as NSNumber
//[images addObject:[NSNumber numberWithInt:x]];
}
我無法加入NSInteger
。如何增加NSInteger
至NSMutableArray
?具有碰撞

NSInteger不是類 'typedef int NSInteger; typedef unsigned int NSUInteger;' 看到它被聲明爲。 U應該轉換爲某些類,並且類對象可以添加到NSArray。 – dayitv89
