//获取缓存的大小
NSUInteger intg = [[SDImageCache sharedImageCache] getSize];
//
NSString * currentVolum = [NSString stringWithFormat:@"%@",[self fileSizeWithInterge:intg]];
//计算出大小
- (NSString *)fileSizeWithInterge:(NSInteger)size{
// 1k = 1024, 1m = 1024k
if (size < 1024) {// 小于1k
return [NSString stringWithFormat:@"%ldB",(long)size];
}else if (size < 1024 * 1024){// 小于1m
CGFloat aFloat = size/1024;
return [NSString stringWithFormat:@"%.0fK",aFloat];
}else if (size < 1024 * 1024 * 1024){// 小于1G
CGFloat aFloat = size/(1024 * 1024);
return [NSString stringWithFormat:@"%.1fM",aFloat];
}else{
CGFloat aFloat = size/(1024*1024*1024);
return [NSString stringWithFormat:@"%.1fG",aFloat];
}
}
