当我在ARC模式下写以下代码的时候,编译器报错 Semantic Issue: Property's synthesized getter follows Cocoa naming convention for returning 'owned' objects @interface ViewController : UIViewController { NSString *newTitle; } @property (strong, nonatomic) NSString *newTitle;…

ARC 全称:Automatic Reference Counting 使用ARC 只需要在建立一个新的项目的时候把 下面的√打上 Xcode5以后都会默认建议开发者使用ARC机制 新的项目中如果有部分文件不想使用ARC就 在Build Phases中找到那个文件 后面修改成-fno-objc-arc 就得项目中如果有部分文件想使用ARC就 Build Phases中找到那个文件 后面修改成-f-objc-arc 在使用了ARC开发程序中不能再出现release或者autorelease 否则就…

在项目中经常会遇到解析json的情况,如果有同学想要解析JSON,那么JSONKit可以是一个不错的选择. git中JSONKit 的地址为:https://github.com/johnezang/JSONKit 由于项目已经很久没有更新,仍然使用了MRC,因此在使用时需要做几处修改: 1.把JSONKit设置为不支持arc的模式,在Build Phases ->Compile Sources 选择文件双击,在对话框中添加“-fno-objc-arc”参数(不含引号). 2.此时编译仍然会出现…

今日帮着同事把老项目从MRC迁移至ARC,大部分工作无非是删除release,［super dealloc］等方法,只要关闭了MRC编译选项后,编译器能自动帮你检查,block就有一些不一样了,发现许多做iOS开发的同学,对于指针的原理及操作并不明确.下面的如果有错误,也欢迎指正. __blcok __block关键字在MRC和ARC下并不一样 MRC:用__block修饰的对象在block中不被retain,就像ARC中的__weak类似. ARC:用__block修饰的变量在被block捕获…
