在我回击纽顿时,我想结束背景。 页: 1
原标题:I want to quit background threads when I touch back button . in ios

我的节目用d子进行。

-(void) viewdidLoad {

    dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_HIGH,0),
    ^ {
        for(int i=0; i<screenshotNum ; i++)
        {
            NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];  

            NSString * url=[detailItem.mScreenshot objectAtIndex:i];

            NSDictionary *args=[NSDictionary dictionaryWithObjectsAndKeys:
                                [NSNumber numberWithInt:i], @"screenNum",
                                [NSString stringWithString:url],@"url",
                                nil];

                               [self loadImageScreenshot:args];

            [pool release]; 
        }
    });
}

当Idismiss ModalViewController时,问题依然存在。

在我回击纽顿时,我想宣布这些read。

-(void) BackButtonPressed:(id)sender
{
    [self dismissModalViewControllerAnimated:YES];
}

我如何增加守则?
