菊花加载第三方--MBprogressHUD

上次说到了网络请求AFN,那么我们在网络请求的时候,等待期间,为了让用户不认为是卡死或程序出错,一般都会放一个菊花加载,系统有一个菊花加载类叫UIProgressHUD.但是我今天要说的是一个替代它的第三方,叫做:MBProgressHUD.MBProgressHUD不光加载效果多,而且使用简单,便捷.github上有下载地址

下载地址是： http://github.com/matej/MBProgressHUD

先下载MBProgressHUD.h和.m文件，拖入工程。

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]; 

需要注意的是,MBprogressHUD的代理方法

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