problem about alloc #11

Closed canran closed 5 years ago

canran commented 8 years ago

when i use "currentAllocationSummary" i get this(part of):

2016-10-10 17:05:18.659 memorydemo[2434:1653842] summary className is __NSArrayI 2016-10-10 17:05:18.659 memorydemo[2434:1653842] summary allocations num is 0 2016-10-10 17:05:18.659 memorydemo[2434:1653842] summary deallocations num is 63 2016-10-10 17:05:18.659 memorydemo[2434:1653842] summary aliveObjects num is -63 2016-10-10 17:05:18.659 memorydemo[2434:1653842] summary instanceSize num is 16 2016-10-10 17:05:18.659 memorydemo[2434:1653842]

my code is : NSArray abc =[[NSArray alloc]init]; NSMutableArray acc =[[NSMutableArray alloc]init];

the important thing is why allocations is 0?

thanks

Hey! Can you show more code? How FBAllocationTracker is allocated? I'd like to repro this. Things like that could happen if we turn off allocation tracker after all sorts of initializations - therefore this allocs wouldn't get captured.

canran commented 8 years ago

i mean that if i use NSMutableArray *acc =[[NSMutableArray alloc]init];,it cann't be allocated then i hook malloc and use getclassname,it can show _arrayI

the code is

-(void)switchOn:(UISwitch *)sender { if(sender.isOn){ [[FBAllocationTrackerManager sharedManager] startTrackingAllocations]; [[FBAllocationTrackerManager sharedManager] enableGenerations]; NSLog(@"开关开启"); }else{ [[FBAllocationTrackerManager sharedManager] stopTrackingAllocations]; [[FBAllocationTrackerManager sharedManager] disableGenerations]; NSLog(@"开关关闭"); }

}

-(void)switchOnmalloc:(UISwitch *)sender { if(sender.isOn){ turnOnMallocTracker(); NSLog(@"开关开启"); }else{ turnOffMallocTracker(); NSLog(@"开关关闭"); }

}

ui is

// twocontroller * two = [[twocontroller alloc]init]; // twocontroller * three = [[twocontroller alloc]init]; // NSArray abc =[[NSArray alloc]init]; // NSMutableArray acc =[[NSMutableArray alloc]init]; // NSString *string = @"this is string";

CGRect rect = [[UIScreen mainScreen] bounds];
CGSize size = rect.size;
CGFloat width = size.width;
//            CGFloat height = size.height;
//            label.backgroundColor = [UIColor clearColor];
if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7.0) {
    label.frame =CGRectMake(width - label.frame.size.width - 300.0,\
                            28, label.frame.size.width, label.frame.size.height);
} else {
    // label.frame =CGRectMake(cell.frame.size.width - label.frame.size.width - 20,\
    12, label.frame.size.width, label.frame.size.height);
}

cell.textLabel.text=Summary.className;
label.text = [NSString stringWithFormat:@"alloc: %li dealloc: %li alive: %li size:%li",
              Summary.allocations,
              Summary.deallocations,
              Summary.aliveObjects,
              Summary.instanceSize];
label.backgroundColor = [UIColor clearColor];
label.textColor = [UIColor grayColor];
[label sizeToFit];
[cell.contentView addSubview:label];
// Configure the cell...

return cell;

}

NSArray is represented by a class cluster therefore it wouldn't be visible as NSArray, but rather, as you saw, as __NSArrayI (or something else).

I am not sure what the problem is, but if you are turning FBAllocationTracker after you've created your tableView then the cells could already be generated and the allocs for these arrays wouldn't be captured.

Can you try starting FBAllocationTracker right in main or in didFinishLaunching method in app delegate?

canran commented 8 years ago

in didFinishLaunching method:

then the result is
