Question

I was trying to customizing the UIBarButtonItem in Navigation Bar
I found that there is a property in UIBarButtonItem : “tintColor” , and I set it like this

self.navigationItem.leftBarButtonItem.tintColor = [UIColor redColor];  

It works well, but if I try this :

self.navigationItem.leftBarButtonItem.tintColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"imageName"]];  

1. It doesn’t work as expect , however , the leftBarButtonItem shows a black appearance ,why ?

If I try a clearColor :

self.navigationItem.leftBarButtonItem.tintColor = [UIColor clearColor];  

2. The leftBarButtonItem shows a black appearance still, why ?

3. I want to customize it with a pattern image like above , how can I do that ?

Thank you
