ios 数组转化 nsDAtA

1. 这是最快的方法(但相当危险),以获得数组: unsigned char *bytesArray = data.bytes; NSUInteger lengthOfBytesArray = data.length; 试图让字节#100之前,你应该检查lengthOfBytesArray这样的: if (lengthOfBytesArray > 100 + 1) { un...

软件找人写 啊堂

char buf[]="123456"; NSData *bufObj=[NSData dataWithBytes:(const void *)buf length:sizeof buf]; if(bufObj==nil) NSLog(@"failed to create obj"); else { NSMutableArray *marr=[NSMutableArray array]; [marr addObject:bufObj]; NSArra...

1.最简单的方法: public static String reverse1(String str) { return new StringBuffer(str).reverse().toString(); } 2.最常用的方法: public static String reverse3(String s) { char[] array = s.toCharArray(); String reverse = ""; /...

NSMutableData *data = [[NSMutableData alloc] init]; for (int i = 0; i < [array count]; ++i ){ NSString *str = [array objectAtIndex:i]; NSData *temp = [str dataUsingEncoding:NSUTF8StringEncoding]; [data appendData:temp]; }

#import @interface NSObject (JSONCategories) /** * 描述:将NSArray或者NSDictionary转化为NSData * 参数: * 返回值:转化后的NSData * */ -(NSData*)JSONData; /** * 描述:将NSArray或者NSDictionary转化为NSString * 参数: * 返回值:转...

NSData *data = [NSData new]; /*不可变数组*/ NSArray *array = @[data]; /*可变数组*/ NSMutableArray *mutableArray = [NSMutableArray array]; //添加元素 [mutableArray addObject:data];
