的UIImageView內存泄漏

Question

在我的應用程序，我加載一系列圖片來我UIImageView已在init方法創建像

- (UIImage *)getImage:(int)currentIndex { 
    NSString *path = [self getImagePath:currentIndex]; 
    [self.imageView setAccessibilityLabel:path]; 

    path=[bundle pathForResource:path ofType:extension];  
    return [UIImage imageWithContentsOfFile:path] ; 

} 

- (void)changeImage:(int)currentIndex { 

    [self.imageView setImage:nil ]; 
    [self.imageView setImage:[self getImage:currentIndex]]; 

} 

但這個代碼會導致內存泄漏.Something像

-malloc - 7KB - imageIO - png_malloc

我已經嘗試過「[[UIImage alloc] initWithContentsOfFile]」，但仍然沒有運氣。

我在這裏錯過了什麼。

大約全班

- (id)initWithFrame:(CGRect)frame andBundle:(NSBundle *) bundleTobeInjected { 

    self = [super initWithFrame:frame]; 
    if (self) { 
     // Initialization code. 
    self.opaque = YES; 
     bundle=bundleTobeInjected; 
     commonFunctions=[[Common alloc] init]; 
     self.imageView = [[UIImageView alloc] initWithFrame:frame] ; 
     [self.imageView setImage:nil ]; 
     self.imageView.contentMode = self.contentMode; 
     [self addSubview:imageView]; 
     [self setAccessibilityEnabled]; 
    } 
    return self; 
} 
-(void)setAccessibilityEnabled 
{ 
    self.imageView.isAccessibilityElement=true; 
} 

#pragma mark - Custom Logic 
- (NSString *)getImagePath:(int)currentIndex { 

    NSString *path = [NSString stringWithFormat:@"%@%d%@", prefix,currentIndex,[commonFunctions imageNamedSmartForRotationSuffix]]; 
    NSLog(@"%@", path); 
    return path; 
} 

- (UIImage *)getImage:(int)currentIndex { 
    NSString *path = [self getImagePath:currentIndex]; 
    [self.imageView setAccessibilityLabel:path]; 

    path=[bundle pathForResource:path ofType:extension];  
    return [UIImage imageWithContentsOfFile:path] ; 

} 

-(void)changeImage:(int)currentIndex { 


    [self.imageView setImage:nil ]; 
    [self.imageView setImage:[self getImage:currentIndex]]; 


} 


-(void)dealloc{ 
    [extension release]; 
    [prefix release]; 
    [defaultImage release]; 
    [image release]; 
    [imageView release]; 
    [commonFunctions release]; 
    [super dealloc]; 
}

代碼不泄漏。您的泄漏位於其他地方:)

泄漏位於init方法中。看這句話：

self.imageView = [[UIImageView alloc] initWithFrame:frame]; 

這行創建的形象圖您擁有因爲你使用的init方法。然後，您將其分配給您的財產，它再次擁有它，因爲我猜你的財產是retain。你需要釋放的ImageView您已經將其分配後，你的財產，是這樣的：

self.imageView = [[[UIImageView alloc] initWithFrame:frame] autorelease];

PS你並不需要這一行

[self.imageView setImage:nil ];
