使用UILabel iOS的自定义UIView

Question

I have a UIView with two UILabel that I want to reuse in more than one UIViewController . I use storyboard and I assign a custom class alertView:UIView that I declared. file AlertRemote.h

@interface AlertRemote: UIView
@property (weak, nonatomic) IBOutlet UILabel *label1;
@property (weak, nonatomic) IBOutlet UILabel *label2;
-(void) setTextLabel;

file AlertRemote.m

-(void) setTextLabel{
    [ _label1 setText:@"attention..."];
    [_label2 setText:@"the program..."];
}

file Controllo.m

//the view present in the storyboard alertView linked to the uiview
@property (strong, nonatomic)IBOutlet AlertRemote *alertView; 
@property AlertRemote *alRemView;
[super viewDidLoad];
_alertView=_alRemView; [_alertView setTextLabel];
[_alertView setTextLabel];

if I put some breakpoints inside setTextLabel the code don't works thanks!!

Answer 1

In order for the custom alert to work, you need to initialise it.

AlertRemote *alRemView;

alRemView = [[AlertRemote alloc]init];
[alRemView setTextLabel];

Answer 2

I think you are not initializing the property alertview. If you are initializing the property alertview then try to set directly with out using alremView.
