Question

我想在我的代码中使用SDWebImage来使用我的图像缓存，但我想使用圆形图像。

使用此代码，我可以使用圆形图像并完美运行：

NSString *imageURL = [noticia objectForKey:@"imagem"];

UIImageView *imgView=[[UIImageView alloc] initWithFrame:CGRectMake(20, 5, 90, 70)];
imgView.backgroundColor=[UIColor clearColor];
[imgView.layer setCornerRadius:30];
[imgView.layer setMasksToBounds:YES];
[imgView setImageWithURL:[NSURL URLWithString:imageURL]];
cell.imageView.image = UIGraphicsGetImageFromCurrentImageContext();
[cell.contentView addSubview:imgView];

但我需要使用SDWebImage和缓存，所以我有这个代码：

[cell.imageView setImageWithURL:[NSURL URLWithString:imageURL] placeholderImage:[UIImage imageNamed:@"placeholder.png"] ];

我想知道如何合并代码以使用SDWebImage和圆形图像。

我尝试了这段代码，但没有奏效：

UIImageView *imgView=[[UIImageView alloc] initWithFrame:CGRectMake(20, 5, 90, 70)];
imgView.backgroundColor=[UIColor clearColor];
[imgView.layer setCornerRadius:30];
[imgView.layer setMasksToBounds:YES];
[imgView setImageWithURL:[NSURL URLWithString:imageURL]];
[cell.imageView setImageWithURL:[NSURL URLWithString:imageURL] placeholderImage:[UIImage imageNamed:@"placeholder.png"] ];
[cell.contentView addSubview:imgView];

试试这个：替换您的代码

  UIImageView *imgView=[[UIImageView alloc] initWithFrame:CGRectMake(20, 5, 90, 70)];
  imgView.backgroundColor=[UIColor clearColor];
 [imgView.layer setCornerRadius:30];
 [imgView.layer setMasksToBounds:YES];
 [imgView setImageWithURL:[NSURL URLWithString:imageURL]];
 [cell.imageView setImageWithURL:[NSURL URLWithString:imageURL] placeholderImage:[UIImage imageNamed:@"placeholder.png"] ];

使用以下代码并导入“QuartzCore / QuartzCore.h”框架

 cell.imageView.backgroundColor=[UIColor clearColor];
 [cell.imageView.layer setCornerRadius:30];
 [cell.imageView.layer setMasksToBounds:YES];
 [cell.imageView setImageWithURL:[NSURL URLWithString:imageURL] placeholderImage:       [UIImage imageNamed:@"placeholder.png"] ];
