Ios SVProgressHUD-显示/隐藏控件会使它在下次调用showWithStatus时无法显示

我有一些源代码下面将复制这一点。在HUD有机会出现之前调用

showWithStatus

并解除，会导致控件在下次调用

showWithStatus

时不显示。有人知道什么解决办法吗

// Commenting these will show SVProgressHUD
[SVProgressHUD showWithStatus:@"Loading..."];
[SVProgressHUD dismiss];
// Comment above to show SVProgressHUD

[SVProgressHUD showWithStatus:@"Loading..."];
[self performSelector:@selector(dismissHUD) withObject:nil afterDelay:5.0f];

---

编辑：我这里有一些复制了它。

我通过在第二个HUD显示器上这样做来解决这个问题：

[self performSelector:@selector(showHud) withObject:nil afterDelay:0.1];

---

我已经解决了这个问题：

1。添加属性

@property (nonatomic, readonly, getter = isDismissing) BOOL dismissing;

- (void)showImage:(UIImage)image status:(NSString)status duration:(NSTimeInterval)duration  

- (void)showImageSS:(UIImage)image status:(NSString)status duration:(NSTimeInterval)duration

- (void)showImage:(UIImage*)image status:(NSString*)status duration:(NSTimeInterval)duration
{
    if(self.isDismissing){
        __weak SVProgressHUD *weakSelf = self;
        dispatch_after(dispatch_time(DISPATCH_TIME_NOW, NSEC_PER_SEC * SVProgressHUDDefaultAnimationDuration),dispatch_get_main_queue(), ^{
            [weakSelf showImageSS:image status:status duration:duration];
        });
    }else{
        [self showImageSS:image status:status duration:duration];
    }
}

- (void)showImageSS:(UIImage*)image status:(NSString*)status duration:(NSTimeInterval)duration
{
    // this is orginal function - (void)showImage:(UIImage)image status:(NSString)status duration:(NSTimeInterval)duration code block
}  

2.添加标志

- (void)dismissWithDuration:(NSTimeInterval)duration delay:(NSTimeInterval)delay {
    _dismissing = YES;
    ...
        void (^completionBlock)(void) = ^{
            ...
            _dismissing = NO;
        };
    ...
}

重命名功能

@property (nonatomic, readonly, getter = isDismissing) BOOL dismissing;

- (void)showImage:(UIImage)image status:(NSString)status duration:(NSTimeInterval)duration  

- (void)showImageSS:(UIImage)image status:(NSString)status duration:(NSTimeInterval)duration

- (void)showImage:(UIImage*)image status:(NSString*)status duration:(NSTimeInterval)duration
{
    if(self.isDismissing){
        __weak SVProgressHUD *weakSelf = self;
        dispatch_after(dispatch_time(DISPATCH_TIME_NOW, NSEC_PER_SEC * SVProgressHUDDefaultAnimationDuration),dispatch_get_main_queue(), ^{
            [weakSelf showImageSS:image status:status duration:duration];
        });
    }else{
        [self showImageSS:image status:status duration:duration];
    }
}

- (void)showImageSS:(UIImage*)image status:(NSString*)status duration:(NSTimeInterval)duration
{
    // this is orginal function - (void)showImage:(UIImage)image status:(NSString)status duration:(NSTimeInterval)duration code block
}  

带名称的收件人

@property (nonatomic, readonly, getter = isDismissing) BOOL dismissing;

- (void)showImage:(UIImage)image status:(NSString)status duration:(NSTimeInterval)duration  

- (void)showImageSS:(UIImage)image status:(NSString)status duration:(NSTimeInterval)duration

- (void)showImage:(UIImage*)image status:(NSString*)status duration:(NSTimeInterval)duration
{
    if(self.isDismissing){
        __weak SVProgressHUD *weakSelf = self;
        dispatch_after(dispatch_time(DISPATCH_TIME_NOW, NSEC_PER_SEC * SVProgressHUDDefaultAnimationDuration),dispatch_get_main_queue(), ^{
            [weakSelf showImageSS:image status:status duration:duration];
        });
    }else{
        [self showImageSS:image status:status duration:duration];
    }
}

- (void)showImageSS:(UIImage*)image status:(NSString*)status duration:(NSTimeInterval)duration
{
    // this is orginal function - (void)showImage:(UIImage)image status:(NSString)status duration:(NSTimeInterval)duration code block
}  

3.添加延迟

@property (nonatomic, readonly, getter = isDismissing) BOOL dismissing;

- (void)showImage:(UIImage)image status:(NSString)status duration:(NSTimeInterval)duration  

- (void)showImageSS:(UIImage)image status:(NSString)status duration:(NSTimeInterval)duration

- (void)showImage:(UIImage*)image status:(NSString*)status duration:(NSTimeInterval)duration
{
    if(self.isDismissing){
        __weak SVProgressHUD *weakSelf = self;
        dispatch_after(dispatch_time(DISPATCH_TIME_NOW, NSEC_PER_SEC * SVProgressHUDDefaultAnimationDuration),dispatch_get_main_queue(), ^{
            [weakSelf showImageSS:image status:status duration:duration];
        });
    }else{
        [self showImageSS:image status:status duration:duration];
    }
}

- (void)showImageSS:(UIImage*)image status:(NSString*)status duration:(NSTimeInterval)duration
{
    // this is orginal function - (void)showImage:(UIImage)image status:(NSString)status duration:(NSTimeInterval)duration code block
}  

和

@property (nonatomic, readonly, getter = isDismissing) BOOL dismissing;

- (void)showImage:(UIImage)image status:(NSString)status duration:(NSTimeInterval)duration  

- (void)showImageSS:(UIImage)image status:(NSString)status duration:(NSTimeInterval)duration

- (void)showImage:(UIImage*)image status:(NSString*)status duration:(NSTimeInterval)duration
{
    if(self.isDismissing){
        __weak SVProgressHUD *weakSelf = self;
        dispatch_after(dispatch_time(DISPATCH_TIME_NOW, NSEC_PER_SEC * SVProgressHUDDefaultAnimationDuration),dispatch_get_main_queue(), ^{
            [weakSelf showImageSS:image status:status duration:duration];
        });
    }else{
        [self showImageSS:image status:status duration:duration];
    }
}

- (void)showImageSS:(UIImage*)image status:(NSString*)status duration:(NSTimeInterval)duration
{
    // this is orginal function - (void)showImage:(UIImage)image status:(NSString)status duration:(NSTimeInterval)duration code block
}

finsh感谢所有人

如果能就官方GitHub项目提交一份bug报告，那就太好了。作者很可能对答案了如指掌。尽管如此，+1用于提供一个测试用例。我做到了。。但有几个悬而未决的问题，我想我可能会在这里更快地得到帮助：）当然，这没什么错。只是觉得通知维护人员很重要，这样其他人（包括我自己）就不会在将来遇到同样的问题。很高兴你这么做：-）我会在那里发表评论，希望它能吸引更多的注意力。
