先看效果圖
這個是矩形
這個是矩形
這個是圓形
這個是圓形
基本思路就是在一個View 上加上蒙版 msak 。不貼代碼的都是流氓,So ,代碼如下:
#pragma mark - ===== 新手指引 =====
/**
* 新手指引
*/
- (void)newUserGuide
{
// 這里創建指引在這個視圖在window上
CGRect frame = [UIScreen mainScreen].bounds;
UIView * bgView = [[[UIView alloc]initWithFrame:frame]autorelease];
bgView.backgroundColor = HEX_RGBA(0x323232, 0.8);
UITapGestureRecognizer * tap = [[[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(sureTapClick:)]autorelease];
[bgView addGestureRecognizer:tap];
[[UIApplication sharedApplication].keyWindow addSubview:bgView];
//create path 重點來了(**這里需要添加第一個路徑)
UIBezierPath *path = [UIBezierPath bezierPathWithRect:frame];
// 這里添加第二個路徑 (這個是圓)
[path appendPath:[UIBezierPath bezierPathWithArcCenter:CGPointMake(frame.size.width - 30, 42) radius:30 startAngle:0 endAngle:2*M_PI clockwise:NO]];
// 這里添加第二個路徑 (這個是矩形)
//[path appendPath:[[UIBezierPath bezierPathWithRoundedRect:CGRectMake(frame.size.width/2.0-1, 234, frame.size.width/2.0+1, 55) cornerRadius:5] bezierPathByReversingPath]];
CAShapeLayer *shapeLayer = [CAShapeLayer layer];
shapeLayer.path = path.CGPath;
//shapeLayer.strokeColor = [UIColor blueColor].CGColor;
[bgView.layer setMask:shapeLayer];
UIImageView * imageView = [[[UIImageView alloc]initWithFrame:CGRectMake(frame.size.width -300,72,270, 137)]autorelease];
imageView.image = [UIImage imageNamed:@"CouponBoard_guid"];
[bgView addSubview:imageView];
}
/**
* 新手指引確定
*/
- (void)sureTapClick:(UITapGestureRecognizer *)tap
{
UIView * view = tap.view;
[view removeFromSuperview];
[view removeAllSubviews];
[view removeGestureRecognizer:tap];
[[NSUserDefaults standardUserDefaults] setBool:YES forKey:@"firstCouponBoard_iPhone"];
}
其他方法自行google 這里推薦一個博文 提供不同思路。
