On iOS 6 SDK I wrote the following lines of code to display an image inside a button:

NSURL *thumbURL2 = [NSURL URLWithString:@"http://example.com/thumbs/2.jpg"];
NSData *thumbData2 = [NSData dataWithContentsOfURL:thumbURL2];
UIImage *thumb2 = [UIImage imageWithData:thumbData2];
[btn2 setImage:thumb2 forState:UIControlStateNormal];
[self.view addSubview:btn2];

But now with Xcode 5 and iOS 7 this doesn't work. The button doesn't contain the image. The button is filled with blue color.

Does the image show up when you click the button?JustAnotherCoder

In iOS7 there is new button type called UIButtonTypeSystem NS_ENUM_AVAILABLE_IOS(7_0), // standard system button

Check your .xib file and change button type to Custom Look at the image

To do this programmatically, add this line to the viewDidLoad:

[UIButton buttonWithType:UIButtonTypeSystem];

It seems iOS 7 is using the image provided just as an Alpha mask for displaying the button's tint color. Changing the button type to UIButtonTypeCustom did the trick for me (thanks user716216!). Setting the image as background doesn't always work if you already have a background image, as was my case.

Swift 3, 4, 5 :

let image = UIImage(named: "my-image")
myButton.setImage(image.withRenderingMode(.alwaysOriginal), for: .normal)

There's a good chance that the image is there and you just can't see it. Try changing the button's type to UIButtonTypeCustom. If that doesn't work, set the button's background color to [UIColor clearColor];

For swift:

The issue is the TintColor. By default, iOS throws a blue tint color over every button. You can get around it through 3 ways.

  1. Change the tint color. [button setTintColor:[UIColor blackColor]]; This may color your image in ways you don't want it to.

  2. As most other suggested, set the background image. [button setBackgroundImage:[UIImage...]];

  3. Add an UIImageView to your button.

UIImageView * img = [[UIImageView alloc] initWithImage:[UIImage...]];

[button addSubView:img];

I had the same issue. On my storyboard I had a button without any image.

I would then assign the image in the code.

IOS 7 came and I got a lot of blue images.

The resolution was simple yet confusing. If I assign any image on the storyboard and then change the image at run time it works fine.

You always must specify a starting image on the storyboard even if you are not going to use it.

This worked for me

[myButton1 setBackgroundImage:[UIImage imageNamed:@"phones.png"] forState:UIControlStateNormal];

Note:Remove front image before doing this.

Old thread, but I wanted to chime in because I just had the same problem. The issue was just that you are calling setImage when you should call setBackgroundImage.

None of the given solutions were working for me. If you do not set an initial image in Storyboard, you can still change the image of the button by using setBackgroundImage.

For your example, only a minor change is needed.

NSURL *thumbURL2 = [NSURL URLWithString:@"http://example.com/thumbs/2.jpg"];
NSData *thumbData2 = [NSData dataWithContentsOfURL:thumbURL2];
UIImage *thumb2 = [UIImage imageWithData:thumbData2];
[btn2 setBackgroundImage:thumb2 forState:UIControlStateNormal];
[self.view addSubview:btn2];

This Problem is called blue color problem of the button in xcode. When we make button by code the button shows the blue tint color by default.This can be solved byt assigning tint color to black or white accordingly to your cell's color. The code is :

UIImage *closebtnimg = [UIImage imageNamed:@"icon_uncheck.png"];
 UIImage *closebtnimg1 = [UIImage imageNamed:@"icon_checked.png"];

Custombutton *button = [Custombutton buttonWithType:UIButtonTypeRoundedRect];
[button setFrame:CGRectMake(52, 66, 25, 24)];
[button setBackgroundImage:closebtnimg forState:UIControlStateNormal];
[button setBackgroundImage:closebtnimg1 forState:UIControlStateSelected];
[button setTintColor:[UIColor whiteColor]];
[cell.contentView addSubview:button];
[button addTarget:self action:@selector(changeImage:)  forControlEvents:UIControlEventTouchUpInside];

Using Xcode 9.2 none of the above solutions worked for what I was looking for.

I was looking for a solution that will let me set .normal and .selected UIControlState images inside the storyboard for their original rendering mode, but, inside the Swift file, no string literals should exist regarding the image names.

Basically, inside your code you will get the image you set inside your storyboard for .normal state and re-render it as .alwaysOriginal (Same for .selected state), then, you will set that image (which is now rendered as original and won't be affected by the tint) for the relevant state (.normal and .selected) of your UIButton.

Here it is:

// Get your .normal image (you set via your storyboard) and render it as original
let unselectedImage = yourButton.image(for: .normal)?.withRenderingMode(.alwaysOriginal)
// Set your normal image but this time rendered as original
yourButton.setImage(unselectedImage, for: .normal)
// Same for selected state
let selectedImage = yourButton.image(for: .selected)?.withRenderingMode(.alwaysOriginal)
yourButton.setImage(selectedImage, for: .selected)

This way you can set your button image states and if the image name will change, it won't affect your code.

In Swift 4, initialize your UIButton and assign uyour image Data as follows:

let myButton = UIButton(type: .cutsom)
myButton.setImage(UIImage(data:myImageData), for: .normal)
