ios MBProgressHUD 使用,及二次封装
https://www.cnblogs.com/ningmengcao-ios/p/6698893.html
MBProgressHUD是一个显示HUD窗口的第三方类库,用于在执行一些后台任务时，在程序中显示一个表示进度的loading视图和两个可选的文本提示的HUD窗口。MBProgressHUD 二次封装网上有很多教程,大多数我们在 MVC 模式下发送网络大多都在 UIVIewCOntroller 进行,需要使用弹窗的地方大多也都在controller 中,所有之前给 UIViewCOntroller 写了个分类,方便调用,但是后来觉得在基类中使用不太好,所以今天重新整理一下. demo 地址:https://github.com/SummerHH/YJMBProgressHUD.git
先了解下 MBProgressHUD 使用:
HUD窗口的模式:
// 使用UIActivityIndicatorView来显示进度，这是默认值
MBProgressHUDModeIndeterminate,
// 使用一个圆形饼图来作为进度视图
MBProgressHUDModeDeterminate,
// 使用一个水平进度条
MBProgressHUDModeDeterminateHorizontalBar,
// 使用圆环作为进度条
MBProgressHUDModeAnnularDeterminate,
// 显示一个自定义视图，通过这种方式，可以显示一个正确或错误的提示图
MBProgressHUDModeCustomView,
// 只显示文本
MBProgressHUDModeText
一个MBProgressHUD视图主要由四个部分组成:
1.标题文本
@property (strong, nonatomic, readonly) UILabel *label;
2.详情文本
@property (strong, nonatomic, readonly) UILabel *detailsLabel;
3.loading动画视图
@property (strong, nonatomic, nullable) UIView *customView;
4.HUD背景框
@property (strong, nonatomic, readonly) MBBackgroundView *bezelView;
外观属性:
设置颜色 默认为半半透明的黑色和白色的iOS 7和早iOS版本
@property (strong, nonatomic, nullable) UIColor *contentColor UI_APPEARANCE_SELECTOR;
//设置显示大小
@property (assign, nonatomic) CGSize minSize UI_APPEARANCE_SELECTOR;
//隐藏后从父视图中移除
@property (assign, nonatomic) BOOL removeFromSuperViewOnHide;
//是否显示蒙版,不过1.0.0版本被弃用了
@property (assign) BOOL dimBackground;
- (void)drawRect:(CGRect)rect {
...
if (self.dimBackground) {
//Gradient colours
size_t gradLocationsNum = 2;
CGFloat gradLocations[2] = {0.0f, 1.0f};
CGFloat gradColors[8] = {0.0f,0.0f,0.0f,0.0f,0.0f,0.0f,0.0f,0.75f};
CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB();
CGGradientRef gradient = CGGradientCreateWithColorComponents(colorSpace, gradColors, gradLocations, gradLocationsNum);
CGColorSpaceRelease(colorSpace);
//Gradient center
CGPoint gradCenter= CGPointMake(self.bounds.size.width/2, self.bounds.size.height/2);
//Gradient radius
float gradRadius = MIN(self.bounds.size.width , self.bounds.size.height) ;
// 由中心向四周绘制渐变
CGContextDrawRadialGradient (context, gradient, gradCenter,
0, gradCenter, gradRadius,
kCGGradientDrawsAfterEndLocation);
CGGradientRelease(gradient);
}
...
}
//创建布局
- (id)initWithView:(UIView *)view;
控制布局的属性
// HUD相对于父视图中心点的x轴偏移量和y轴偏移量
@property (assign) float xOffset;
@property (assign) float yOffset;
// HUD各元素与HUD边缘的间距
@property (assign) float margin;
// HUD背景框的最小大小
@property (assign) CGSize minSize;
// HUD的实际大小
@property (atomic, assign, readonly) CGSize size;
// 是否强制HUD背景框宽高相等
@property (assign, getter = isSquare) BOOL square;
//显示和隐藏的方法
- (void)showAnimated:(BOOL)animated;
- (void)hideAnimated:(BOOL)animated;
经常在 UIViewController 中使用,可以给 UIVIewController 写个分类
使用简单方便

@end
@implementation UIViewController (HUD)

另一种可以配合网络使用,也可以 用在 Controller中
