Thestringtype supportsvariable-length character strings. The library takes care of managingthe memory associated with storing the characters and providesvarious useful operations. The librarystringtype is intended to be efficient enough for general use. string类型支持长度可变的字符串,C++标准库将负责管理与...
self.myString = @"Test"; 还可以使用set的方法,如下所示: [self setMyString:@"Test"]; 类别(categories) 类用于将方法添加到现有类。通过这种方法可以将方法添加到类,甚至不用执行文件,就可以在其中定义实际的类。MyClass的样本类别,如下所示: @interface MyClass(customAdditions) - (void)sampleCategoryMet...
@interfacePerson:NSObject{@publicNSString*name;@privateintage;}@property(copy)NSString*name;@property(readonly)intage;-(id)initWithAge:(int)age;@end 性的访问方法由@synthesize关键字来实现,它由属性的声明自动的产生一对访问方法。另外,也可以选择使用@dynamic关键字表明访问方法会由程序员手工提供。

Every config is constructed with four components: architecture string, ABI, reuse rule with architecture string and reuse rule with sub-extension. Re-use part support expansion operator (*) to simplify the combination of different sub-extensions, example 4 demonstrate how it uses and works. ...
A backslash immediately before a newline has long been used to continue string literals, as well as preprocessing command lines. In the interest of easing machine generation of C, and of transporting code to machines with restrictive physical line lengths, the C89 Committee generalized this mechani...
