项目中有使用，直接标记一下，没有怎么整理代码
先看效果图
一：雷达效果（这个很简单，使用的三方库，VIGRadarView，可以直接搜到）
使用：
#import "VIGRadarView.h"
@property (nonatomic, strong) VIGRadarView *radarView;
-(VIGRadarView *)radarView {
if (!_radarView) {
_radarView = [[VIGRadarView alloc] initWithFrame:self.view.bounds];
_radarView.scanSpeed = 0.5;
[self.view addSubview:_radarView];
}
return _radarView;
}
//VIGRadarView.m中 scanPartCircle.png 为雷达线，scanCircle.png 为线圈 可自行更改
- (void)viewDidLoad {
[super viewDidLoad];
//开始
[self.radarView start];
//离开时关闭
// [self.radarView stop];
}
二，水波纹
//中间动画
CAShapeLayer *shapeLayer = [CAShapeLayer layer];
shapeLayer.frame = CGRectMake(self.view.center.x-95, self.view.center.y-95, 190, 190);
shapeLayer.path = [UIBezierPath bezierPathWithOvalInRect:CGRectMake(0, 0, 190, 190)].CGPath;
//shapeLayer.fillColor = [UIColor colorWithRed:255/255.0 green:158/255.0 blue:27/255.0 alpha:1.0].CGColor;//黄色
shapeLayer.fillColor = [UIColor colorWithRed:198/255.0 green:201/255.0 blue:220/255.0 alpha:1.0].CGColor;//蓝色
shapeLayer.opacity = 0.0;
CAAnimationGroup *animationGroup = [CAAnimationGroup animation];
animationGroup.animations = @[[self alphaAnimation],[self scaleAnimation]];
animationGroup.duration = 3.2;
animationGroup.autoreverses = NO;
animationGroup.repeatCount = HUGE;
[shapeLayer addAnimation:animationGroup forKey:@"animationGroup"];
CAReplicatorLayer *replicatorLayer = [CAReplicatorLayer layer];
replicatorLayer.frame = CGRectMake(0, 0, 190, 190);
replicatorLayer.instanceDelay = 0.8;
replicatorLayer.instanceCount = 4;
[replicatorLayer addSublayer:shapeLayer];
[self.view.layer addSublayer:replicatorLayer];
- (CABasicAnimation *)alphaAnimation{
CABasicAnimation *alpha = [CABasicAnimation animationWithKeyPath:@"opacity"];
alpha.fromValue = @(1.0);
alpha.toValue = @(0.0);
return alpha;
}
- (CABasicAnimation *)scaleAnimation{
CABasicAnimation *scale = [CABasicAnimation animationWithKeyPath:@"transform"];
scale.fromValue = [NSValue valueWithCATransform3D:CATransform3DScale(CATransform3DIdentity, 0.0, 0.0, 0.0)];
scale.toValue = [NSValue valueWithCATransform3D:CATransform3DScale(CATransform3DIdentity, 1.5, 1.5, 0.0)];
return scale;
}三，随机选5个位置放置搜索到的人
//从数据元中随机选5个数据
NSMutableArray *randomArray = [[NSMutableArray alloc] init];
//取随机5个数据
while ([randomArray count] < 5) {
int r = arc4random() % [self.tempArr count];
[randomArray addObject:[self.tempArr objectAtIndex:r]];
}
[self createFivePlaceWithArrar:randomArray];
- (void)createFivePlaceWithArrar:(NSArray *)dataArr
{
@autoreleasepool {
BOOL creat = YES;
NSInteger count = 0;
//存放搜索到的人 _img为中间头像
NSMutableArray *arr = [NSMutableArray arrayWithObject:_img];
while (creat) {
FH_UserInfoModel *model = dataArr[count];
//放置搜索到的人
FH_RadioButton *personBtn = [[FH_RadioButton alloc] init];
CGFloat x = arc4random_uniform(Main_Screen_Width);
CGFloat y = arc4random_uniform(Main_Screen_Height);
personBtn.frame = CGRectMake(x, y, 70, 100);
/*
//数据赋值（可忽略）
personBtn.photoImg.backgroundColor = [UIColor cyanColor];
personBtn.name.text = [NSString stringWithFormat:@"%@",model.nickName];
if([model.relatoin isEqualToString:@"red"]){
personBtn.stateImg.backgroundColor = [UIColor redColor];
}else if ([model.relatoin isEqualToString:@"yellow"]){
personBtn.stateImg.backgroundColor = [UIColor yellowColor];
}else{
personBtn.stateImg.backgroundColor = [UIColor greenColor];
}
personBtn.tag = count+1009;
[personBtn addTarget:self action:@selector(cleckPerson:) forControlEvents:UIControlEventTouchUpInside];
*/
BOOL isMutul = NO;
for (int i=0; i<arr.count; i++) {
UIView *viewBtn = arr[i];
//超出这个区域 跳出
if(CGRectIntersectsRect(personBtn.frame, viewBtn.frame) || x<0 || x>=Main_Screen_Width-70 || y<=64 || y>= Main_Screen_Height-100){
isMutul = YES;
break;
}
}
if(!isMutul && creat ){
[arr addObject:personBtn];
[self.view addSubview:personBtn];
count++;
}
//最多展示5个数据
if(count == 5) creat = NO;
/*
没有处理数据源，只是从数据源中找出5个
if(_dataArr.count ==0 ) creat = NO;
if(_dataArr.count <5 && _dataArr.count >0){
if(count == _dataArr.count) creat = NO;
}else{
if(count == 5) creat = NO;
}
*/
}
}
}
四：刷新旋转
//换一批按钮
- (void)changeFriendClick:(UIButton *)sender
{
//旋转
CABasicAnimation *animation = [CABasicAnimation animationWithKeyPath:@"transform.rotation.z"];
//默认是顺时针效果，若将fromValue和toValue的值互换，则为逆时针效果
animation.fromValue = [NSNumber numberWithFloat:0.f];
animation.toValue = [NSNumber numberWithFloat: M_PI *2];
animation.duration = 1;
animation.autoreverses = NO;
animation.fillMode = kCAFillModeForwards;
animation.repeatCount = 1; //如果这里想设置成一直自旋转，可以设置为MAXFLOAT，否则设置具体的数值则代表执行多 少次
[self.refreshImg.layer addAnimation:animation forKey:@"updateBtnRotation"];
if(self.tempArr.count >0){
//清除上次所寻找的人
for (UIView *subView in self.view.subviews) {
if([subView isKindOfClass:[FH_RadioButton class]]){
[subView removeFromSuperview];
}
}
//人数大于5 继续随机展示
if(self.tempArr.count>5){
NSMutableArray *randomArray = [[NSMutableArray alloc] init];
while ([randomArray count] < 5) {
int r = arc4random() % [self.tempArr count];
[randomArray addObject:[self.tempArr objectAtIndex:r]];
}
[self createFivePlaceWithArrar:randomArray];
[self.tempArr removeObjectsInArray:randomArray];//数据不重复
}else{//人数少于5 就全部显示
[self createFivePlaceWithArrar:self.tempArr];
}
}else{
}
}五，弹出视图(三方库：YBPopupMenu，可以直接搜到)
#import "YBPopupMenu.h"
//遵循代理 <YBPopupMenuDelegate>
@property (nonatomic, strong) YBPopupMenu* rightPopMenu;//右侧更多下拉框
//右侧按钮点击事件
- (void)rightItemClick:(UIButton *)click
{
NSArray* items = @[@"查看全部",@"只看红灯好友",@"只看黄灯好友",@"只看绿灯好友"];
self.rightPopMenu = [YBPopupMenu showRelyOnView:click titles:items icons:nil menuWidth:125 otherSettings:^(YBPopupMenu *popupMenu) {
popupMenu.isShowShadow = NO;
popupMenu.showMaskView = NO;
popupMenu.backColor = [[UIColor blackColor] colorWithAlphaComponent:0.85];
popupMenu.textColor = [UIColor whiteColor];
popupMenu.maxVisibleCount = 7;
popupMenu.itemHeight = 36;
popupMenu.lineSpace = 12;
}];
self.rightPopMenu.delegate = self;
}
#pragma mark YBPopupMenuDelegate
- (void)ybPopupMenuDidSelectedAtIndex:(NSInteger)index ybPopupMenu:(YBPopupMenu *)ybPopupMenu
{
NSLog(@"index:L%lu",index);
//处理数据
}
