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:
