iOS——MBProgressHUD的使用方法

MBProgressHUD就是一个非常好用的第三方库，可以快速接入加载的界面，下面贴代码，下面的代码包含了各种常用类型的加载：

#import "ViewController.h"
#import "MBProgressHUD.h"

@interface ViewController ()

@property (atomic, assign) BOOL canceled;

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
}

//仅显示加载的图标
- (IBAction)indeterminateExample:(id)sender
{
    MBProgressHUD *hud = [MBProgressHUD showHUDAddedTo:self.view animated:YES];
    dispatch_async(dispatch_get_global_queue(QOS_CLASS_USER_INITIATED, 0), ^{
        [self doSomeWork];
        dispatch_async(dispatch_get_main_queue(), ^{
            [hud hideAnimated:YES];
        });
    });
}

- (IBAction)With_details_label:(id)sender
{
    MBProgressHUD *hud = [MBProgressHUD showHUDAddedTo:self.view animated:YES];
    hud.label.text = NSLocalizedString(@"Loading...", @"HUD loading title");
    hud.detailsLabel.text = NSLocalizedString(@"Parsing data\n(1/1)", @"HUD title");

    dispatch_async(dispatch_get_global_queue(QOS_CLASS_USER_INITIATED, 0), ^{
        [self doSomeWork];
        dispatch_async(dispatch_get_main_queue(), ^{
            [hud hideAnimated:YES];
        });
    });
}

- (IBAction)With_label:(id)sender
{
    MBProgressHUD *hud = [MBProgressHUD showHUDAddedTo:self.view animated:YES];
    hud.label.text = @"正在加载";
    dispatch_async(dispatch_get_global_queue(QOS_CLASS_USER_INITIATED, 0), ^{
        [self doSomeWork];
        dispatch_async(dispatch_get_main_queue(), ^{
            [hud hideAnimated:YES];
        });
    });
}

- (IBAction)Circle_style:(id)sender
{
    MBProgressHUD *hud = [MBProgressHUD showHUDAddedTo:self.view animated:YES];
    hud.mode = MBProgressHUDModeDeterminate;
    hud.label.text =  @"正在加载";
    dispatch_async(dispatch_get_global_queue(QOS_CLASS_USER_INITIATED, 0), ^{
        [self doSomeWorkWithProgress];
        dispatch_async(dispatch_get_main_queue(), ^{
            [hud hideAnimated:YES];
        });
    });
}

- (IBAction)Progress_style:(id)sender
{
    MBProgressHUD *hud = [MBProgressHUD showHUDAddedTo:self.view animated:YES];
    hud.mode = MBProgressHUDModeDeterminateHorizontalBar;
    hud.label.text = @"正在加载";
    dispatch_async(dispatch_get_global_queue(QOS_CLASS_USER_INITIATED, 0), ^{
        [self doSomeWorkWithProgress];
        dispatch_async(dispatch_get_main_queue(), ^{
            [hud hideAnimated:YES];
        });
    });
}

- (IBAction)Text_only:(id)sender
{
    MBProgressHUD *hud = [MBProgressHUD showHUDAddedTo:self.view animated:YES];
    hud.mode = MBProgressHUDModeText;
    hud.label.text = @"正在加载";
    hud.offset = CGPointMake(0.f, MBProgressMaxOffset);

    [hud hideAnimated:YES afterDelay:3.f];
}

- (IBAction)With_action_button:(id)sender
{
    MBProgressHUD *hud = [MBProgressHUD showHUDAddedTo:self.view animated:YES];
    hud.mode = MBProgressHUDModeDeterminate;
    hud.label.text = @"正在加载";
    [hud.button setTitle:@"取消" forState:UIControlStateNormal];
    [hud.button addTarget:self action:@selector(cancelWork:) forControlEvents:UIControlEventTouchUpInside];
    dispatch_async(dispatch_get_global_queue(QOS_CLASS_USER_INITIATED, 0), ^{
        [self doSomeWorkWithProgress];
        dispatch_async(dispatch_get_main_queue(), ^{
            [hud hideAnimated:YES];
        });
    });
}

- (IBAction)Custom_view:(id)sender
{
    MBProgressHUD *hud = [MBProgressHUD showHUDAddedTo:self.view animated:YES];
    hud.mode = MBProgressHUDModeCustomView;
    UIImage *image = [[UIImage imageNamed:@"Checkmark"] imageWithRenderingMode:UIImageRenderingModeAlwaysTemplate];
    hud.customView = [[UIImageView alloc] initWithImage:image];
    hud.square = YES;
    hud.label.text = @"已完成";
    [hud hideAnimated:YES afterDelay:1.5f];
}

- (void)doSomeWorkWithProgress {
    self.canceled = NO;
    float progress = 0.0f;
    while (progress < 1.0f) {
        if (self.canceled) break;
        progress += 0.01f;
        dispatch_async(dispatch_get_main_queue(), ^{
            [MBProgressHUD HUDForView:self.view].progress = progress;
        });
        usleep(50000);
    }
}

-(void)doSomeWork
{
    //加载时候处理的事件和方法
    NSLog(@"正在加载");

    //显示加载的时间
    sleep(1.5);
}

- (void)cancelWork:(id)sender {
    self.canceled = YES;
}

- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

@end
