MONActivityIndicatorView 是一个用于 iOS 的出色的自定义活动指示器视图。
安装
手动安装
- 复制并将文件
MONActivityIndicatorView.h和MONActivityIndicatorView.m添加到您的项目中。 - 将 QuartzCore 框架添加到您的项目中。
- 然后执行，
import MONActivityIndicatorView.h
用法
初始化
- (void)viewDidLoad {
[super viewDidLoad];
MONActivityIndicatorView *indicatorView = [[MONActivityIndicatorView alloc] init];
[self.view addSubview:indicatorView];
}切换指示器
[indicatorView startAnimating];
[indicatorView stopAnimating];自定义
默认属性值
- 动画延迟 :
delay = 0.2 - 动画时长 :
duration = 0.8 - 圆圈数量 :
numberOfCircles = 5 - 圆圈的半径 :
radius = 10 - 圆圈的内部间距 :
internalSpacing = 5 - 圆圈的背景颜色 :
defaultColor = [UIColor lightGrayColor]
自定义属性值
- (void)viewDidLoad {
[super viewDidLoad];
MONActivityIndicatorView *indicatorView = [[MONActivityIndicatorView alloc] init];
indicatorView.numberOfCircles = 3;
indicatorView.radius = 20;
indicatorView.internalSpacing = 3;
indicatorView.duration = 0.5;
indicatorView.delay = 0.5
indicatorView.center = self.view.center;
[self.view addSubview:indicatorView];
[indicatorView startAnimating];
}自定义圆圈背景颜色
首先，将 MONActivityIndicatorViewDelegate 协议分配给一个视图控制器。然后，实现方法 activityIndicatorView:circleBackgroundColorAtIndex:
@interface ViewController : UIViewController <MONActivityIndicatorViewDelegate>
@end
@implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
MONActivityIndicatorView *indicatorView = [[MONActivityIndicatorView alloc] init];
indicatorView.delegate = self;
indicatorView.numberOfCircles = 3;
indicatorView.radius = 20;
indicatorView.internalSpacing = 3;
indicatorView.duration = 0.5;
indicatorView.delay = 0.5
indicatorView.center = self.view.center;
[self.view addSubview:indicatorView];
[indicatorView startAnimating];
}
- (UIColor *)activityIndicatorView:(MONActivityIndicatorView *)activityIndicatorView
circleBackgroundColorAtIndex:(NSUInteger)index {
// For a random background color for a particular circle
CGFloat red = (arc4random() % 256)/255.0;
CGFloat green = (arc4random() % 256)/255.0;
CGFloat blue = (arc4random() % 256)/255.0;
CGFloat alpha = 1.0f;
return [UIColor colorWithRed:red green:green blue:blue alpha:alpha];
}
@end
