如何以编程方式将UIImage添加到UIImageView然后将该UIImageView添加到另一个UIView？

Question

As the title says, I'm trying to create a UIImage that will go inside a UIImageView (so that I can animate it later) then I want to put that UIImageView into another classes UIView .

So far my relevant code is:

This is the viewDidLoad for my root view controller:

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view from its nib.
    self.playerViewController = [[TUKIPlayerViewController alloc] init];
    [self.view addSubview:playerViewController.view];
}

And this is the init for the UIImageView :

- (id)init
{
    if (self = [super init]) {
        playerIdle = [UIImage imageNamed:@"playerIdle.png"];
        playerView = [[UIImageView alloc] initWithImage:playerIdle];
        self.view = playerView;
    }
    return self;
}

It builds and runs with 0 errors.

What am I doing wrong? I don't see the playerIdle.png anywhere. Though I'm betting I'm doing this terribly wrong.

Answer 1

In your ViewController , add the imageview directly...

- (void)viewDidLoad
{
   playerView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"playerIdle.png"]];
   [self.view addSubView: playerView];
}

Answer 2

Try this:

UIImageView *imgView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"name.png"]];
[self.view addSubview:imgView];

Answer 3

Pls try the below code :

- (id)init 
{
     if (self = [super init]) {
         playerIdle = [UIImage imageNamed:@"playerIdle.png"];
         playerView = [[UIImageView alloc] initWithImage:playerIdle];
         [self.view addSubview:playerView];
     }
return self; 
} 

Hope this might help you.....

Answer 4

You should use [self.view addSubview:playerView]; instead of just setting it( self.view = playerview; ). What I also do most of the times is bringing that subview to the front:

[self.view bringSubviewToFront:playerView];

Hope it helps

或者您可以尝试： myUIImageViewObject.image = myUIImageObject;

Answer 6

UIImageView *imgView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"name.png"]]; imagView.frame=CGRectMake(40,130,45,45);

[self.view addSubview:imgView];
