                int a = 5;        float b = 5.0;        double c = 5.5 ;        char d = 'a';        bool flag = YES;

        CGPoint point = CGPointMake(3, 4);        CGSize size = CGSizeMake(5, 6);        CGRect rect = CGRectMake(3, 4, 5, 6);        NSRange range = NSMakeRange(10, 3);        NSEdgeInsets edgeInsets = NSEdgeInsetsMake(10, 10, 10, 10);

封装:

//其中NSNumber 可以将'int','float','double','char','bool'等C中基本数据类型转换成对象                NSNumber *intNumber = [NSNumber numberWithInt:a];        NSNumber *floatNumber = [NSNumber numberWithFloat:b];        NSNumber *doubleNumber = [NSNumber numberWithDouble:c];        NSNumber *charNumber = [NSNumber numberWithChar:d];        NSNumber *boolNumber = [NSNumber numberWithBool:flag];

//其中NSValue 可以将CGPoint,CGSize,CGRect,NSRange,NSEdgeInsets转换成对象                NSValue *pointVa = [NSValue valueWithPoint:point];        NSValue *sizeVa = [NSValue valueWithSize:size];        NSValue *rectVa = [NSValue valueWithRect:rect];        NSValue *rangeVa = [NSValue valueWithRange:range];        NSValue *edgeInsetsVa = [NSValue valueWithEdgeInsets:edgeInsets];

拆包:

        int a1 = [intNumber intValue];        float b1 = [floatNumber floatValue];        double c1 = [doubleNumber doubleValue];        char d1 = [charNumber charValue];        bool flag1 =[boolNumber boolValue];                CGPoint point1 = [pointVa pointValue];        CGSize size1 = [sizeVa sizeValue];        CGRect rect1 = [rectVa rectValue];        NSRange range1 = [rangeVa rangeValue];        NSEdgeInsets edgeInsets1 = [edgeInsetsVa edgeInsetsValue];
