ios - iCarousel 不显示我的图像 Objective-C

Question

我想使用 iCarousel 在 View Controller 中显示多个图像。

我在 NSMutableArray foto 中列出我所有的图像，
然后我在 iCarousel 方法 viewForItemAtIndex 中调用数组照片。

我已经按照一些教程进行操作，但仍然无法正常工作。请帮我。

这是我的.m代码

#import "TestController.h"

@interface TestController ()  <UIActionSheetDelegate>

@property (nonatomic, retain) NSMutableArray *foto;


@end


@implementation TestController


@synthesize carousel;
@synthesize foto;


- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        // Custom initialization
        foto = [NSArray arrayWithObjects:
                     [UIImage imageNamed:@"Seleb1.jpg"],
                     [UIImage imageNamed:@"Seleb2.jpg"],
                     [UIImage imageNamed:@"Seleb3.jpg"],
                     nil];
    }
    return self;
}

- (void)dealloc
{

    carousel.delegate = nil;
    carousel.dataSource = nil;
}
- (void)viewDidLoad
{
    [super viewDidLoad];
    carousel.type = iCarouselTypeCoverFlow2;

}

- (void)viewDidUnload
{
    [super viewDidUnload];

    self.carousel = nil;
}


#pragma mark -
#pragma mark iCarousel methods

- (NSUInteger)numberOfItemsInCarousel:(iCarousel *)carousel
{
    return [foto count];
}



- (UIView *)carousel:(iCarousel *)carousel viewForItemAtIndex:(NSUInteger)index reusingView:(UIView *)view
{
    view = [[UIImageView alloc] initWithImage:[UIImage imageNamed:[foto objectAtIndex:index]]];
    return view;
}

@end

有人可以帮助我吗？我的代码有什么问题？

更新代码

#import "TestController.h"

@interface TestController ()  

@property (nonatomic, retain) NSArray *foto;


@end


@implementation TestController


@synthesize carousel;
@synthesize foto;


- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        // Custom initialization
        foto = [NSArray arrayWithObjects:
                @"Seleb1.jpg",
                @"Seleb2.jpg",
                @"Seleb3.jpg",
                nil];
    }
    return self;

}

- (void)dealloc
{

    carousel.delegate = nil;
    carousel.dataSource = nil;
}
- (void)viewDidLoad
{
    [super viewDidLoad];
    carousel.type = iCarouselTypeCoverFlow2;
    [carousel reloadData];
}

- (void)viewDidUnload
{
    [super viewDidUnload];

    self.carousel = nil;

}


#pragma mark -
#pragma mark iCarousel methods

    return [foto count];
}


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

    view = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 200.0f, 200.0f)]; // set the frame for your Image

    UIImage *image  = [UIImage imageNamed:[foto objectAtIndex:index]];
    ((UIImageView *)view).image = image;

    return view;

}

- (CGFloat)carousel:(iCarousel *)carousel valueForOption:(iCarouselOption)option          withDefault:(CGFloat)value
{
    //customize carousel display

    return value+0.1;
}

@end

Answer 1

改变这一行

 view = [[UIImageView alloc] initWithImage:[UIImage imageNamed:[foto objectAtIndex:index]]];

到

Reason : you have already defined your array as [UIImage imageNamed:@"Seleb1.jpg"] , so in here you need call directly like

view = [[UIImageView alloc] initWithImage:[foto objectAtIndex:index]];

选择 2

创建一个数组

  foto = [NSArray arrayWithObjects:
                 @"Seleb1.jpg",
                 @"Seleb2.jpg",
                 @"Seleb3.jpg",
                 nil];

然后调用

 view = [[UIImageView alloc] initWithImage:[UIImage imageNamed:[foto objectAtIndex:index]]];

如果你需要

用这个

- (void)viewDidLoad
{
[super viewDidLoad];
carousel.type = iCarouselTypeCoverFlow2;
[carousel reloadData];
}

更新答案

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

    view = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 200.0f, 200.0f)]; // set the frame for your Image

          UIImage *image  = [UIImage imageNamed:[foto objectAtIndex:index]];
        ((UIImageView *)view).image = image;

        return view;

}
