公司测试反应,有时候出现问题来不及截图..所以写个摇一摇截图
方法写在UIViewController的分类里,无需调用,立即生效
#import "UIViewController+ShakeAndCutter.h"
@implementation UIViewController (ShakeAndCutter)
- (void)motionBegan:(UIEventSubtype)motion withEvent:(UIEvent *)event {
[self snapshot];
}
- (void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event {
NSLog(@"End");
}
- (void)motionCancelled:(UIEventSubtype)motion withEvent:(UIEvent *)event{
NSLog(@"Cancel");
}
- (void)snapshot
{
// 1. 开启图像上下文[必须先开开启上下文再执行第二步，顺序不可改变]
UIGraphicsBeginImageContext(self.view.bounds.size);
// 2. 获取上下文
CGContextRef context = UIGraphicsGetCurrentContext();
// 3. 将当前视图图层渲染到当前上下文
[self.view.layer renderInContext:context];
// 4. 从当前上下文获取图像
UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
// 5. 关闭图像上下文
UIGraphicsEndImageContext();
// 6. 保存图像至相册
UIImageWriteToSavedPhotosAlbum(image, self, @selector(image:didFinishSavingWithError:contextInfo:), nil);
}
#pragma mark 保存完成后调用的方法[格式固定]
- (void)image:(UIImage *)image didFinishSavingWithError:(NSError *)error contextInfo:(void *)contextInfo
{
if (error) {
NSLog(@"error-%@", error.localizedDescription);
}else{
NSLog(@"保存成功");
}
}
需要注意:在plist中添加
