添加到UIView后如何顯示UIImageview動畫

Question

我試圖創建一個自定義視圖，將所有UIImage保存在一個數組中，然后將此數組分配給UIImageView的animationImages屬性。

但是問題是，如果我在想要的UIViewController中執行此操作，則此方法正常，但是當我嘗試通過自定義UIView創建此控件時，它不顯示任何內容。

這是我的代碼：

@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

我將其用作：

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

您應該使用bounds因為您是相對於內部矩形進行bounds 。
_indicatorView = [[UIImageView alloc] initWithFrame:self.frame];
改成
_indicatorView = [[UIImageView alloc] initWithFrame:self.bounds];
