1、获取设备类型（Iphone/ipad 几？）

 #import "sys/utsname.h"-(NSString*)getDeviceVersion{    struct utsname systemInfo;    uname(&systemInfo);    NSString *deviceString = [NSString stringWithCString:systemInfo.machine encoding:NSUTF8StringEncoding];    return deviceString;}

2、获取系统时间

    NSDate* date = [NSDate date];      NSDateFormatter* formatter = [[[NSDateFormatter alloc] init] autorelease];    [formatter setDateFormat:@"yyyy-MM-dd HH:MM:SS"];    [formatter stringFromDate:date];

3、获取应用版本手机系统版本信息

  UIDevice* uiDevice = [UIDevice currentDevice];      NSBundle* nsBundle = [NSBundle mainBundle];    NSDictionary *infoDictionary = [nsBundle infoDictionary];    NSString* crashInfo = [NSString stringWithFormat:@"Identifier:%@\nVersion:%@\nOS Version:%@     %@\nDate/Time:%@\nHardware Model:%@",                        [nsBundle bundleIdentifier],                        [infoDictionary objectForKey:@"CFBundleVersion"],                        [uiDevice systemName],                        [uiDevice systemVersion],                        [self GetOnlyTime],                        [self deviceString] ];

4、获取应用程序目录

    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES);    NSString *cacheDir = [paths objectAtIndex: 0];

5、创建应用程序内部文件夹

    NSFileManager *fm = [NSFileManager defaultManager];        NSDictionary *attributes = [NSDictionary dictionaryWithObject: [NSNumber numberWithUnsignedLong: 0755] forKey: NSFilePosixPermissions];        if(![fm fileExistsAtPath:"文件路径"]){            [fm createDirectoryAtPath:"文件路径"withIntermediateDirectories:YES attributes:attributes error:NULL];        }

6、获取某个文件夹下所有文件及删除以某后缀名结尾文件

    NSFileManager *fm = [NSFileManager defaultManager];    NSArray *contents = [fm contentsOfDirectoryAtPath:path error:NULL];    NSEnumerator *e = [contents objectEnumerator];    NSString *filename;    while ((filename = [e nextObject])) {        NSLog(@"file Name = %@",filename);        if ([[filename pathExtension] isEqualToString:@"txt"]||[[filename pathExtension] isEqualToString:@"plcrash"]) {            [path stringByAppendingPathComponent:filename];        }     }
