而且这行代码得到一个信号SIGABRT错误:

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);
}
}
答
尝试编辑该代码:
[HUD showWhileExecuting:@selector(load) onTarget:self withObject:nil animated:YES];
要:
[HUD showWhileExecuting:@selector(load:) onTarget:self withObject:nil animated:YES];
答
变换load
方法(void)
- (void) load {
}
您的代码:
- (void) load {
{
float progress = 0.0;
while (progress < 1.0) {
progress += 0.01;
HUD.progress = progress;
usleep(50000);
}
}
你能告诉你如何使用它?它以常见的方式在运行时崩溃。该对象不响应该选择器。 –
