Question

I’m a newbie trying to figure out a memory leak problem. Does anyone see anything wrong with the following code?

- (void)viewWillAppear:(BOOL)animated {
[super viewWillAppear:animated];
[self.navigationController.navigationBar setTintColor:[UIColor colorWithRed:0.10 green:.20 blue:0.30 alpha:1]];
}

In case it helps, Instruments shows the leaked block with the following info…

Event Type: Malloc

Responsible Library: CoreGraphics

Responsible Caller: CGTypeCreateInstanceWithAllocator

Any help would be greatly appreciated. (I’m still very new, so please explain in as much detail as possible.)

Much thanks!

Answer 1

Bit of a long shot but I’m not sure if it was just a bug in my project or not but I had a similar issue once when setting tintColor in viewWillAppear. I ended up adding an nil check before assigning the color again and this cleared it up for me (I didn’t do any further investigation into it so I could be wrong).

if (nil == self.navigationController.navigationBar.tintColor) {
  self.navigationController.navigationBar = [UIColor colorWithRed:0.10 green:.20 blue:0.30 alpha:1];
}
