触摸在我的自定义类中未调用的开始方法

Question

在我的iPhone应用程序视图中,我添加了一个子视图,这是一个自定义类.我有这个自定义类的.h和.m文件,它继承自Image View.

问题是触摸开始我的viewcontroller方法被调用,而不是自定义类的触摸开始方法.

我在想的是当我image class view在我看来触摸这个时:

/* Assign Categories */

Category *category1=[[Category alloc] initWithName:[[categoriesMArray objectAtIndex:0] valueForKey:@"category_name"]  identity:[[[categoriesMArray objectAtIndex:0] valueForKey:@"category_id"] intValue] imageName:[[categoriesMArray objectAtIndex:0] valueForKey:@"category_image"]];
[category1 setFrame:CGRectMake(10,10, 150, 150)];

Category *category2=[[Category alloc] initWithName:[[categoriesMArray objectAtIndex:1] valueForKey:@"category_name"]  identity:[[[categoriesMArray objectAtIndex:1] valueForKey:@"category_id"] intValue] imageName:[[categoriesMArray objectAtIndex:1] valueForKey:@"category_image"]];
[category2 setFrame:CGRectMake(170,10, 150, 150)];


NSLog(@"Categories %@",category3.imageName);
[self.view addSubview:category1];
[self.view addSubview:category2];
[self.view bringSubviewToFront:category1];

它应该调用我的自定义类部分:

@implementation Category
@synthesize categoryName,categoryID,imageName;

- (id)initWithFrame:(CGRect)frame
{
    self = [super initWithFrame:frame];
    if (self) {
        // Initialization code
    }
    return self;
}

- (id)initWithName:(NSString *)name identity:(int)index imageName:(NSString *)imgName
{
    if ((self = [super init])) {
        self.categoryName = name;
        self.categoryID =index;
        self.imageName=imgName;
        UIImage *temptoResize=[UIImage imageNamed:self.imageName];

        [super setImage:[temptoResize scaleToSize:CGSizeMake(200, 150)]];


    }    
    return self;

}

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
    NSLog(@"Category Touch %@",self.frame);


}

// ------------------------

-touchesBegan method我的自定义类而不是我的视图控制器.

请告诉我为什么我的自定义类方法没有被调用.

好的,在你的

- (id)initWithName:(NSString *)name identity:(int)index...

方法,添加以下行

self.userInteractionEnabled = YES;

因为它默认为NO.请参阅UIImageView Apple文档.
