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。
#import "ViewController.h"
#import "MBProgressHUD.h" #define iOS7 [[[UIDevice currentDevice] systemVersion] floatValue]>=7.0
@interface ViewController ()<MBProgressHUDDelegate> @end @implementation ViewController - (void)viewDidLoad {
[super viewDidLoad];
[self createView]; //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 =[NSArray arrayWithObjects:@"菊花怪",@"圆饼图",@"进度条",@"圆环",@"文字",@"自定义",nil];
for (int i=0; i<HudTypeArray.count; i++) {
UIButton *hudButton =[UIButton buttonWithType:UIButtonTypeCustom];
hudButton.frame = CGRectMake(50, (50+20)*i+44+20, 100, 50);
[hudButton setTitle:HudTypeArray[i] forState:UIControlStateNormal];
[hudButton setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];
hudButton.backgroundColor =[UIColor orangeColor];
hudButton.tag = 1000+i;
[hudButton addTarget:self action:@selector(hudAction:) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:hudButton];
}
} //设置hud的提示文字、样式、代理等等
- (void)hudAction:(UIButton *)button { MBProgressHUD *HUD =[MBProgressHUD showHUDAddedTo:self.view animated: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) {
case 0:
//菊花怪
HUD.mode =MBProgressHUDModeIndeterminate; //加载效果的显示样式 break;
case 1:
//圆饼图
HUD.mode = MBProgressHUDModeDeterminate;
break;
case 2:
//进度条
HUD.mode =MBProgressHUDModeDeterminateHorizontalBar; break;
case 3:
//圆环
HUD.mode =MBProgressHUDModeAnnularDeterminate; break;
case 4:
//文字
HUD.mode =MBProgressHUDModeText; break;
case 5:
//自定义
HUD.mode =MBProgressHUDModeCustomView; break; default:
break;
} if (button.tag-1000==5) {
[self custonView:HUD]; //自定义HUD效果
}else{
[self animationHud: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), ^{
float progress = 0.0f;
while (progress < 1.0f) {
progress += 0.01f;
dispatch_async(dispatch_get_main_queue(), ^{
[MBProgressHUD HUDForView:self.view].progress = progress;
});
usleep(50000);
} dispatch_async(dispatch_get_main_queue(), ^{
[hud hideAnimated:YES];
});
});
}
//自定义视图
- (void)custonView:(MBProgressHUD *)hud{
NSMutableArray *contingentArray =[NSMutableArray array];

- (void)hudWasHidden:(MBProgressHUD *)hud {
[hud removeFromSuperview];
hud = nil;
} - (void)didReceiveMemoryWarning {
