此代码行也会收到信号SIGABRT错误：

[targetForExecution performSelector:methodForExecution withObject:objectForExecution];

编辑：

// MBProgressHUD
HUD = [[MBProgressHUD alloc] initWithView:self.view];
HUD.labelText = @"Uploading to Cloud...";
HUD.detailsLabelText = @"Just relax";
HUD.mode = MBProgressHUDModeAnnularDeterminate;
[self.view addSubview:HUD];
[HUD show:YES];

[HUD showWhileExecuting:@selector(load) onTarget:self withObject:nil animated:YES];

-(NSArray*) load: (NSString *) componentName
{
    float progress = 0.0;

    while (progress < 1.0) {
        progress += 0.01;
        HUD.progress = progress;
        usleep(50000);
    }
}

Answer 1

尝试编辑此代码：

[HUD showWhileExecuting:@selector(load) onTarget:self withObject:nil animated:YES];

要：

[HUD showWhileExecuting:@selector(load:) onTarget:self withObject:nil animated:YES];

Answer 2

在load

中转换(void)方法

- (void) load {
}

您的代码：

- (void) load {
{
    float progress = 0.0;
    while (progress < 1.0) {
        progress += 0.01;
        HUD.progress = progress;
        usleep(50000);
    }
}
