加载图片时候带有中文或特殊符号需要编码
//先去编码
NSString *trimPath = [imageUrl stringByRemovingPercentEncoding];
//拼接数据
NSString *newUrl = [NSString stringWithFormat:@"%@?imageView2/1/w/%ld/h/%ld/q/85",trimPath,wh,wh];
//排查？号进行编码
NSString *finurl = newUrl.mj_urlEncodedString
@property (nonatomic, strong) UIImageView *Img;
- (UIImageView *)Img {
if (!_Img) {
UIImageView *imgeView = [[UIImageView alloc] init];
imgeView.image = [UIImage imageNamed:@"logo_del_pro"];
imgeView.backgroundColor = [UIColor grayColor];
imgeView.userInteractionEnabled = YES;
UITapGestureRecognizer *tap=[[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(titleImgClick:)];
[imgeView addGestureRecognizer:tap];
_Img = imgeView;
}
return _Img;
}
[self.Img makeConstraints:^(MASConstraintMaker *make) {
make.left.right.equalTo(self.view);
make.height.equalTo(@30);
make.width.equalTo(@30);
}];
#pragma mark ************** 个人背景被点击
-(void)titleImgClick:(UITapGestureRecognizer *)sender{
}
图片适应
//图片自适应，ImageView会有部分空白
[_titleImg setContentMode:UIViewContentModeScaleAspectFit];
//去图片中间部分，图片太大的情况
[_titleImg setContentMode:UIViewContentModeScaleAspectFill];
_titleImg.clipsToBounds=YES;
调用
[self.imvIcon sd_setImageWithURL:[model.image mj_stringEncodeUrl] placeholderImage:kDefaultImage];
计算图片高度
__block CGFloat viewH = 0;
[_productImg sd_setImageWithURL:imgUrl placeholderImage:[UIImage imageNamed:@"logo_del_pro"] options:SDWebImageLowPriority | SDWebImageRetryFailed completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType, NSURL *imageURL) {
if (image)
{
//判断图片是否有值，避免出现除以零的情况导致崩溃
viewH = SCREEN_WIDTH * image.size.height / image.size.width;
model.cellHeight = viewH;
if(self.cellHeightBlack)
{
self.cellHeightBlack(viewH);
}
}
}];
清除缓存
[[SDImageCache sharedImageCache] clearMemory];
[[SDImageCache sharedImageCache] clearDiskOnCompletion:^{
[SVProgressHUD showSuccessWithStatus:@"成功"];
}];
[[SDImageCache sharedImageCache] deleteOldFilesWithCompletionBlock:^{
[SVProgressHUD showSuccessWithStatus:@"成功"];
}];
}
图片在TableView cell 上的点击事件无法监听
