1.禁止手机睡眠
[UIApplication sharedApplication].idleTimerDisabled = YES;
2、获取app缓存大小
//用枚举器遍历 一个文件夹的内容
- (CGFloat)getCachSize {
//获取自定义缓存大小
NSUIntegerimageCacheSize = [[SDImageCache sharedImageCache] getSize];
//1.获取 文件夹枚举器
NSString*myCachePath = [NSHomeDirectory() stringByAppendingPathComponent:@"Library/Caches"];
NSDirectoryEnumerator*enumerator = [[NSFileManagerdefaultManager] enumeratorAtPath:myCachePath];
__blockNSUIntegercount =0;
//2.遍历
for(NSString*fileNameinenumerator) {
NSString*path = [myCachePath stringByAppendingPathComponent:fileName];
NSDictionary*fileDict = [[NSFileManagerdefaultManager] attributesOfItemAtPath:path error:nil];
count += fileDict.fileSize;
}
// 得到是字节 转化为自定义所有缓存大小
MCGFloat totalSize = ((CGFloat)imageCacheSize+count)/1024/1024;
return totalSize;
}
