Objective c 如何在添加到UIView时显示UIImageview动画

我试图创建一个自定义视图，将所有UIImage保存在一个数组中，然后将此数组指定给UIImageView的animationImages属性

但问题是，如果我在UIViewController中执行此操作（我希望在其中执行此操作），则此操作可以正常工作。但是，当我尝试通过自定义UIView创建此操作时，它不会显示任何内容

这是我的密码：

@interface IndicatorView : UIView

@property(nonatomic, strong) UIImageView * indicatorView;
-(void)createIndicator;
-(void)startAnimating;
-(void)stopAnimating;

@end

#import "ConfIndicatorView.h"

@implementation ConfIndicatorView


- (id)initWithFrame:(CGRect)frame
{
    self = [super initWithFrame:frame];
    if (self) {
        // Initialization code
        [self createIndicator];

    }
    return self;
}


-(void)createIndicator
{
    NSArray * imageArray  = [[NSArray alloc] initWithObjects:
                             [UIImage imageNamed:@"spinner-1.png"],
                             [UIImage imageNamed:@"spinner-2.png"],
                             [UIImage imageNamed:@"spinner-3.png"],
                             nil];
    _indicatorView = [[UIImageView alloc] initWithFrame:self.frame];
    _indicatorView.animationImages = imageArray;
    _indicatorView.animationDuration = 1.0f;
    _indicatorView.contentMode = UIViewContentModeCenter;
[self addSubview:_indicatorView];
    [_indicatorView startAnimating];// Just added this to see if it works but still not
}
-(void)startAnimating
{
    [_indicatorView startAnimating];
}
-(void)stopAnimating
{
    [_indicatorView stopAnimating];
}

/*
// Only override drawRect: if you perform custom drawing.
// An empty implementation adversely affects performance during animation.
- (void)drawRect:(CGRect)rect
{
    // Drawing code
}
*/

@end

我用它来表示：

_spinner = [[IndicatorView alloc]initWithFrame:CGRectMake(160, 240, 80, 80)];
    [self.view addSubview:_spinner];
[_spinner startAnimating];

您应该使用

bounds

，因为这样做是相对于内部rect的。

\u indicatorView=[[UIImageView alloc]initWithFrame:self.frame]

更改为

\u indicatorView=[[UIImageView alloc]initWithFrame:self.bounds]
