UIWebview隐藏滚动条______iOSMD5加密NSString/NSData

在iphone4上可以

[(UIScrollView*)[webview.subviews objectAtIndex:0] setShowsHorizontalScrollIndicator:NO];

[(UIScrollView*)[webview.subviews objectAtIndex:0] setShowsVerticalScrollIndicator:NO];

但是在3上不行

#pragma mark - 一：对字符串NSStringMD5加密算法（// Need to import for CC_MD5 access）

+ (NSString *)md5:(NSString *)inputString {

    

    const char *cStr = [inputString UTF8String];

    unsignedchar result[CC_MD5_DIGEST_LENGTH];

    CC_MD5(cStr,strlen(cStr), result);

    return [[NSStringstringWithFormat:@"%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X",result[0],result[1],result[2],result[3],result[4],result[5],result[6],result[7],result[8],result[9],result[10],result[11],result[12],result[13],result[14],result[15]]lowercaseString];

    

}

+ (NSString *)md5ForDigest:(NSString *)inputString {

    

    const char *cStr = [inputString UTF8String];

    unsigned char result[16];

    CC_MD5(cStr,strlen(cStr), result);

    NSMutableString *hash = [NSMutableStringstring];

    for (int i =0; i<16; i++) {

        [hash appendFormat:@"%02X",result[i]];

    }

    return [hashlowercaseString];

    

}

//二：在字符串类目上扩展MD5

#import <CommonCrypto/CommonDigest.h>

@interface NSString (md5)

-(NSString *) md5HexDigest;

@end

#import "NSString+MD5HexDigest.h"

@implementation NSString (md5)

 

-(NSString *) md5HexDigest

{

   const char *original_str = [self UTF8String];

   unsigned char result[CC_MD5_DIGEST_LENGTH];

   CC_MD5(original_str, strlen(original_str), result);

   NSMutableString *hash = [NSMutableString string];

   for (int i = 0; i < 16; i++)

        [hash appendFormat:@"%02X", result[i]];

   return [hash lowercaseString];

}
