iOS：MBProgressHUD的基本使用

下载地址：https://github.com/jdg/MBProgressHUD/

//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:];  

//只显示文字
MBProgressHUD *hud = [MBProgressHUD showHUDAddedTo:self.view animated:YES];
hud.mode = MBProgressHUDModeText;
hud.labelText = @"Some message...";
hud.margin = .f;
hud.yOffset = .f;
hud.removeFromSuperViewOnHide = YES;
[hud hide:YES afterDelay:];  

//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:];  

代理方法：

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

二个task

 -(void) doTask{
    //你要进行的一些逻辑操作
    sleep();
  }  

  -(void) myProgressTask{
       float progress = 0.0f;
while (progress < 1.0f) {
    progress += 0.01f;
    HUD.progress = progress;
    usleep();
}  

  } 

注意： 其实，第三方库都是开源的，我们可以在其基础上添加另外自己需要的功能，如果觉得上面显示文字代码太不好用，可以添加一个分类，对它设置文字的方法再次封装如下所示：

添加一个分类：MBProgressHUD+XYQ

MBProgressHUD+XYQ.h文件：

#import "MBProgressHUD"

@interface MBProgressHUD (XYQ)
+ (void)showSuccess:(NSString *)success toView:(UIView *)view;
+ (void)showError:(NSString *)error toView:(UIView *)view;

+ (MBProgressHUD *)showMessage:(NSString *)message toView:(UIView *)view;

+ (void)showSuccess:(NSString *)success;
+ (void)showError:(NSString *)error;

+ (MBProgressHUD *)showMessage:(NSString *)message;

+ (void)hideHUDForView:(UIView *)view;
+ (void)hideHUD;

@end

MBProgressHUD+XYQ.m文件：

#import "MBProgressHUD+XYQ.h"

@implementation MBProgressHUD (XYQ)
#pragma mark 显示信息
+ (void)show:(NSString *)text icon:(NSString *)icon view:(UIView *)view
{
    if (view == nil) view = [[UIApplication sharedApplication].windows lastObject];
    // 快速显示一个提示信息
    MBProgressHUD *hud = [MBProgressHUD showHUDAddedTo:view animated:YES];
    hud.labelText = text;
    // 设置图片
    hud.customView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:[NSString stringWithFormat:@"MBProgressHUD.bundle/%@", icon]]];
    // 再设置模式
    hud.mode = MBProgressHUDModeCustomView;

    // 隐藏时候从父控件中移除
    hud.removeFromSuperViewOnHide = YES;

    // 1秒之后再消失
    [hud hide:YES afterDelay:1.2];
}

#pragma mark 显示错误信息
+ (void)showError:(NSString *)error toView:(UIView *)view{
    [self show:error icon:@"error.png" view:view];
}

+ (void)showSuccess:(NSString *)success toView:(UIView *)view
{
    [self show:success icon:@"success.png" view:view];
}

#pragma mark 显示一些信息
+ (MBProgressHUD *)showMessage:(NSString *)message toView:(UIView *)view {
    if (view == nil) view = [[UIApplication sharedApplication].windows lastObject];
    // 快速显示一个提示信息
    MBProgressHUD *hud = [MBProgressHUD showHUDAddedTo:view animated:YES];
    hud.labelText = message;
    // 隐藏时候从父控件中移除
    hud.removeFromSuperViewOnHide = YES;
    // YES代表需要蒙版效果
    hud.dimBackground = YES;
    return hud;
}

+ (void)showSuccess:(NSString *)success
{
    [self showSuccess:success toView:nil];
}

+ (void)showError:(NSString *)error
{
    [self showError:error toView:nil];
}

+ (MBProgressHUD *)showMessage:(NSString *)message
{
    return [self showMessage:message toView:nil];
}

+ (void)hideHUDForView:(UIView *)view
{
    [self hideHUDForView:view animated:YES];
}

+ (void)hideHUD
{
    [self hideHUDForView:nil];
}
@end
