MBProgressHUD用法

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

@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 <

progress += 0.01f;

dispatch_async(dispatch_get_main_queue(), ^{

});

usleep(50000);

}

dispatch_async(dispatch_get_main_queue(), ^{

[hud hideAnimated:YES];

});

});

}

//自定义视图

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

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

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

[hudImageView startAnimating];
//开始动画

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

[hud hideAnimated:YES
afterDelay:10.0f];
//10s后隐藏HUD
