Question

我的按钮中有一个gif，但它只显示为蓝色框。

 (id)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if (self)
    {
    //[self setTitle:@"Register" forState:UIControlStateNormal];
    [self setBackgroundColor:[UIColor whiteColor]];
    [self setTitleColor:[UIColor darkGrayColor] forState:UIControlStateNormal];



    [self setImage:[UIImage imageNamed:@"Person.gif"] forState:UIControlStateNormal];//setting image on button.
}
return self;

}

图像已正确添加到xcode。是什么给了什么？

不支持iOS GIF图像，因此如果您希望设置Image With Animation，请执行以下代码： -

UIImageView* animatedImageView = [[UIImageView alloc] initWithFrame:self.view.bounds];
animatedImageView.animationImages = [NSArray arrayWithObjects:    
                               [UIImage imageNamed:@"image1.png"],
                               [UIImage imageNamed:@"image2.png"],
                               [UIImage imageNamed:@"image3.png"],
                               [UIImage imageNamed:@"image4.png"], nil];
animatedImageView.animationDuration = 1.0f;
animatedImageView.animationRepeatCount = 0;
[animatedImageView startAnimating];
[yourButton addSubview: animatedImageView];
