iOS常用代码块

这里向各位推荐一些简单常用的代码块

1.添加警告信息

#warning <#message#>

2.忽略 performSeletor 方法内存泄漏提醒

#pragma clang diagnostic ignored "-Warc-performSelector-leaks"

3.Masonry 省略前缀mas_ 的宏命令

/**

*/
//define this constant if you want to use Masonry without the 'mas_' prefix
#define MAS_SHORTHAND

//define this constant if you want to enable auto-boxing for default syntax
#define MAS_SHORTHAND_GLOBALS

// 导入头文件
#import "Masonry.h"

4.打标记

#pragma mark <#message#>

获取主队列

dispatch_async(dispatch_get_main_queue(), ^{
<#code#>
});

6.获取全局并发队列

dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
<#code#>
});

代理属性

@property (nonatomic,weak) id<<#protocol#>> <#delegate#>;

8.block 属性

@property (nonatomic,copy) <#Block#> <#block#>;

afterGCD

dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(<#delayInSeconds#> * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
<#code to be executed after a specified delay#>
});

weak 属性

@property (nonatomic, weak) <#type#> *<#name#>;

11.strong属性

@property (nonatomic,strong) <#type#> *<#name#>;

12.assign 属性

@property (nonatomic,assign) <#type#> <#name#>;

13.copy 属性
