自定义Navigationbaritem

自定义Navigationbaritem

Here's an example that creates a toolbar button from the Facebook logo. Create a pointer to an image (file already added to xCode), create a custom button, change the size of the button to match the image, set image of button, create toolbar button from button view.

UIImage *faceImage = [UIImage imageNamed:@"facebook.png"];UIButton *face = [UIButton buttonWithType:UIButtonTypeCustom];face.bounds = CGRectMake( 0, 0, faceImage.size.width, faceImage.size.height );[face setImage:faceImage forState:UIControlStateNormal];UIBarButtonItem *faceBtn = [[UIBarButtonItem alloc] initWithCustomView:face];

IBarButtonItem alloc] initWithImage:[UIImage imageNamed:@"image.png"] style:UIBarButtonItemStylePlain target:self action:@selector(pp:)]
      3.
