MBProgressHUD中whileExecutingBloc

(转载)

MBProgressHUD版本号：0.9.2

以前用MBProgressHUD用得挺好的，基本上

- (void)showAnimated:(BOOL)animated whileExecutingBlock:(dispatch_block_t)block completionBlock:(void (^)())completion ;

这套方法上去就没事了，但是现在不行了，老是提示要用GCD

'showAnimated:whileExecutingBlock:completionBlock:' is deprecated: Use GCD directly.

没办法，只能去网上下载了:https://github.com/jdg/MBProgressHUD

看了一下Demo，还真改了，上代码吧，方法全在代码里

#import"ViewController.h"

#import"MBProgressHUD.h"

#define iOS7 [[[UIDevice currentDevice] systemVersion] floatValue]>=7.0

@interfaceViewController()

@end

@implementationViewController

- (void)viewDidLoad {

[superviewDidLoad];

[selfcreateView];//创建各种HUD效果的点击按钮

}

//创建各种HUD效果的点击按钮

- (void)createView{

NSArray*HudTypeArray =[NSArrayarrayWithObjects:@"菊花怪",@"圆饼图",@"进度条",@"圆环",@"文字",@"自定义",nil];

for(inti=0; i

UIButton*hudButton =[UIButtonbuttonWithType:UIButtonTypeCustom];

hudButton.frame=CGRectMake(50, (50+20)*i+44+20,100,50);

[hudButtonsetTitle:HudTypeArray[i]forState:UIControlStateNormal];

[hudButtonsetTitleColor:[UIColorwhiteColor]forState:UIControlStateNormal];

hudButton.backgroundColor=[UIColororangeColor];

hudButton.tag=1000+i;

[hudButtonaddTarget:selfaction:@selector(hudAction:)forControlEvents:UIControlEventTouchUpInside];

[self.viewaddSubview:hudButton];

}

}

//设置hud的提示文字、样式、代理等等

- (void)hudAction:(UIButton*)button {

MBProgressHUD*HUD =[MBProgressHUDshowHUDAddedTo:self.viewanimated:YES];//HUD效果添加哪个视图上

HUD.label.text=@"正在努力加载中...";//加载时的提示文字

HUD.detailsLabel.text=@"猪猪侠在这";//详细提示文字，跟UITableViewCell的detailTextLabel差不多

HUD.delegate=self;//我在这里设置，只为实现hudWasHidden方法，使hud消失时能清理对象，省出内存

switch(button.tag-1000) {

case0:

//菊花怪

HUD.mode=MBProgressHUDModeIndeterminate;//加载效果的显示样式

break;

case1:

//圆饼图

HUD.mode=MBProgressHUDModeDeterminate;

break;

case2:

//进度条

HUD.mode=MBProgressHUDModeDeterminateHorizontalBar;

break;

case3:

//圆环

HUD.mode=MBProgressHUDModeAnnularDeterminate;

break;

case4:

//文字

HUD.mode=MBProgressHUDModeText;

break;

case5:

//自定义

HUD.mode=MBProgressHUDModeCustomView;

break;

default:

break;

}

if(button.tag-1000==5) {

[selfcustonView:HUD];//自定义HUD效果

}else{

[selfanimationHud:HUD];////MBProgressHUD自带HUD效果

}

}

//MBProgressHUD自带视图

- (void)animationHud:(MBProgressHUD*)hud {

/**

MBProgressHUD 0.92与先前某些版本很大的不同就包括：舍弃掉了某些方法：比如

以前是这样玩的：

[hud showAnimated:YES whileExecutingBlock:^{

float progress = 0.0f;

while (progress < 1.0f) {

progress += 0.01f;

hud.progress = progress;

usleep(50000);

}

} completionBlock:^{

[hud removeFromSuperview];

hud = nil;

}];

现在不行了，得像下边这样玩:

**/

dispatch_async(dispatch_get_global_queue(QOS_CLASS_USER_INITIATED,0), ^{

floatprogress =0.0f;

while(progress <1.0f) {

progress +=0.01f;

dispatch_async(dispatch_get_main_queue(), ^{

[MBProgressHUDHUDForView:self.view].progress= progress;

});

usleep(50000);

}

dispatch_async(dispatch_get_main_queue(), ^{

[hudhideAnimated:YES];

});

});

}

//自定义视图

- (void)custonView:(MBProgressHUD*)hud{

NSMutableArray*contingentArray =[NSMutableArrayarray];

for(inti=1; i<13; i++) {

NSString*imgName =[NSStringstringWithFormat:@"%d",i];

UIImage*image;

if(iOS7) {

image =[[UIImageimageNamed:imgName]imageWithRenderingMode:UIImageRenderingModeAlwaysTemplate];

}else{

image =[UIImageimageNamed:imgName];

}

[contingentArrayaddObject:image];

}

UIImageView*hudImageView =[[UIImageViewalloc]init];

hudImageView.animationImages=contingentArray;//UIImageView的动画组

hudImageView.animationDuration=1.0;//每次动画的执行时间

hudImageView.animationRepeatCount=0;//设置动画次数，0表示无限

[hudImageViewstartAnimating];//开始动画

hud.customView= hudImageView;//自定义的视图，将会展示为HUD效果

[hudhideAnimated:YESafterDelay:10.0f];//10s后隐藏HUD

}
