1.保存到iOS照片库需要引入QuartzCore.framework框架,具体代码如下:
.h文件
#import<QuartzCore/QuartzCore.h>
UIImageView *imageView;
@property (nonatomic, retain) IBOutlet UIImageView*imageView;
.m文件
UIGraphicsBeginImageContext(imageView.bounds.size);
[imageView.layerrenderInContext:UIGraphicsGetCurrentContext()];
UIImage *temp = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
UIImageWriteToSavedPhotosAlbum(temp, nil, nil, nil);
2.保存到对应的沙盒目录中,具体代码如下:
NSArray *paths =NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask,YES);
NSString *filePath = [[paths objectAtIndex:0]stringByAppendingPathComponent:[NSStringstringWithFormat:@"sms.gif"]]; // 保存文件的名称
BOOL result =[UIImagePNGRepresentation(imageView.image)writeToFile:filePath atomically:YES]; // 保存成功会返回YES
