MBProgressHUD的基本使用

和gitHub上的Demo其实差不多，就是小整理了下，当备忘，想做复杂的效果可以参考MBProgressHUD在gitHub上的DEMO，写得也很清楚明了。

先下载MBProgressHUD.h和.m文件，拖入工程。地址：MBProgressHUD

以下是代码：（先在.h文件里定义 MBProgressHUD *HUD;）

//方式1.直接在View上show
HUD = [[MBProgressHUD showHUDAddedTo:self.view animated:YES] retain];
HUD.delegate = self;

//常用的设置
//小矩形的背景色
HUD.color = [UIColor clearColor];//这儿表示无背景
//显示的文字
HUD.labelText = @"Test";
//细节文字
HUD.detailsLabelText = @"Test detail";
//是否有庶罩
HUD.dimBackground = YES;
[HUD hide:YES afterDelay:2];

//只显示文字
MBProgressHUD *hud = [MBProgressHUD showHUDAddedTo:self.view animated:YES];
hud.mode = MBProgressHUDModeText;
hud.labelText = @"Some message...";
hud.margin = 10.f;
hud.yOffset = 150.f;
hud.removeFromSuperViewOnHide = YES;
[hud hide:YES afterDelay:3];

//方式2.initWithView
//use block
HUD = [[MBProgressHUD alloc] initWithView:self.view];
[self.view addSubview:HUD];
HUD.labelText = @"Test";
[HUD showAnimated:YES whileExecutingBlock:^{
NSLog(@"%@",@"do somethings....");
[self doTask];
} completionBlock:^{
[HUD removeFromSuperview];
[HUD release];
}];

//圆形进度条
HUD = [[MBProgressHUD alloc] initWithView:self.view];
[self.view addSubview:HUD];
HUD.mode = MBProgressHUDModeAnnularDeterminate;
HUD.delegate = self;
HUD.labelText = @"Loading";
[HUD showWhileExecuting:@selector(myProgressTask) onTarget:self withObject:nil animated:YES];

//自定义view
HUD = [[MBProgressHUD alloc] initWithView:self.view];
HUD.customView = [[[UIImageView alloc] initWithImage:[UIImage imageNamed:@"37x-Checkmark.png"]] autorelease];
// Set custom view mode
HUD.mode = MBProgressHUDModeCustomView;
HUD.delegate = self;
HUD.labelText = @"Completed";
[HUD show:YES];
[HUD hide:YES afterDelay:3];

代理方法：

#pragma mark -
#pragma mark HUD的代理方法,关闭HUD时执行
-(void)hudWasHidden:(MBProgressHUD *)hud
{
[hud removeFromSuperview];
[hud release];
hud = nil;
}

二个task

-(void) doTask{
//你要进行的一些逻辑操作
sleep(2);
}

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

}
