我正在使用 MBProgress HUD ,我不知道是什么问题。
我有UIButton
显示 HUD 。
这是我的代码:
- (void)showHUD:(id)sender {
HUD = [[MBProgressHUD alloc] initWithView:self.view];
HUD.mode = MBProgressHUDModeCustomView;
[self.view addSubview:HUD];
HUD.delegate = self;
HUD.labelText = @"No Internet Connection...";
HUD.opacity = 0.7;
HUD.customView =
[[UIImageView alloc] initWithImage:[UIImage imageNamed:@"image.png"]];
[HUD showWhileExecuting:@selector(hudWasHidden)
onTarget:self
withObject:nil
animated:YES];
}
- (void)hudWasHidden {
float progress = 0.0f;
while (progress < 1.0f) {
progress += 0.01f;
HUD.progress = progress;
usleep(50000);
}
}
以下是控制台日志:

单击UIButton
时,我的应用始终崩溃。
由于
答案 0 :(得分:0)
这是Cocoa代码中常见的崩溃:“无法识别的选择器”在这种情况下非常明确。 MBProgressHUD没有customView
属性,并且尝试设置它会导致崩溃。 setCustomView
是在这里调用的隐式选择器(方法),当没有被调用的方法时,Objective-C会崩溃。
不知道如何告诉你如何完成你想要做的事情。
