ios - 怎样从沙盒里读取图片

Question

已把图片保存，读取的时候也有路径，为什么读不到图片？
//存图片
NSData *imageData = UIImageJPEGRepresentation(currentImage, 0.5);
//获取沙盒路径
NSString *fullPath = [[NSHomeDirectory() stringByAppendingPathComponent:@"Documents"] stringByAppendingPathComponent:imageName];
[imageData writeToFile:fullPath atomically:NO];

//读取图片
NSString *fullPath = [[NSHomeDirectory() stringByAppendingPathComponent:@"Docments"] stringByAppendingPathComponent:@"currentImage.png"];
UIImage *savedImage = [[UIImage alloc] initWithContentsOfFile:fullPath];

结果savedImage是空的。

Answer 1

兄弟 你少写了个u;
NSString *fullPath = [[NSHomeDirectory() stringByAppendingPathComponent:@"Docments"] stringByAppendingPathComponent:@"currentImage.png"];
是documents 不是docments

Answer 2

你看看imageData是不是为nil

Answer 3

需要确定保存是否成功了！保存路径和读取路径是否一致！
