让所有界面都显示,最好还是封装一个继承Window的类:JYCWindow。
先看看效果:
关键代码如下:
- (instancetype)initWithFrame:(CGRect)frame mainImageName:(NSString*)name bgcolor:(UIColor *)bgcolor animationColor:animationColor
{
if(self = [super initWithFrame:frame])
{
NSAssert(name != nil, @"mainImageName can't be nil !");
self.backgroundColor = [UIColor clearColor];
self.windowLevel = UIWindowLevelAlert + 1; //如果想在 alert 之上,则改成 + 2
self.rootViewController = [UIViewController new];
[self makeKeyAndVisible];
_bgcolor = bgcolor;
_frameWidth = frame.size.width;
_animationColor = animationColor;
_mainImageButton = [UIButton buttonWithType:UIButtonTypeCustom];
[_mainImageButton setFrame:(CGRect){0, 0,frame.size.width, frame.size.height}];
[_mainImageButton setImage:[UIImage imageNamed:name] forState:UIControlStateNormal];
// _mainImageButton.layer.cornerRadius = frame.size.width*0.5;
// _mainImageButton.layer.masksToBounds= YES;
_mainImageButton.alpha = normalAlpha;
[_mainImageButton addTarget:self action:@selector(click:) forControlEvents:UIControlEventTouchUpInside];
if (_animationColor) {
[_mainImageButton addTarget:self action:@selector(mainBtnTouchDown) forControlEvents:UIControlEventTouchDown];
}
[self addSubview:_mainImageButton];
// 增加拖动window的手势
_pan = [[UIPanGestureRecognizer alloc]initWithTarget:self action:@selector(locationChange:)];
_pan.delaysTouchesBegan = NO;
[self addGestureRecognizer:_pan];
_tap = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(click:)];
[self addGestureRecognizer:_tap];
[self performSelector:@selector(justbegin) withObject:nil afterDelay:statusChangeDuration];
}
return self;
}
至于怎么移动,怎么动画,直接看.h和.m文件如下:
JYCWindow.h###
#import <UIKit/UIKit.h>
typedef void(^CallTheService)(void);
@interface JYCWindow : UIWindow
//重要:所有图片都要是圆形的,程序里并没有自动处理成圆形
// warning: frame的长宽必须相等
- (instancetype)initWithFrame:(CGRect)frame mainImageName:(NSString*)name bgcolor:(UIColor *)bgcolor;
// 长按雷达辐射效果
- (instancetype)initWithFrame:(CGRect)frame mainImageName:(NSString*)name bgcolor:(UIColor *)bgcolor animationColor:animationColor;
// 显示(默认)
- (void)showWindow;
// 隐藏
- (void)dissmissWindow;
@property (nonatomic,copy)CallTheService callService;
@end
