设置静态全局变量 oc swift
静态全局变量分swift和oc版
swift版相对比较简单
struct Example {
static var example:String = ""
}oc
先写设置静态变量的方法
#import
@interface staticPool : NSObject
//静态变量的set get 方法
+(void)setName:(NSString *)Name;
+(NSString *)getName;
+(void)setAge:(NSInteger)Age;
+(NSInteger)getAge;
@end
#import "staticPool.h"
//创建静态全局变量
static NSString *name = nil;
static NSInteger age = 0;
@implementation staticPool
+(void)setName:(NSString *)Name
{
name = Name;
}
+(NSString *)getName
{
return name;
}
+(void)setAge:(NSInteger)Age
{
age = Age;
}
+(NSInteger)getAge
{
return age;
}
@end
然后调用设置
#import "ViewController.h"
#import "PageBViewController.h"
#import "staticPool.h"
@interface ViewController ()
@end
@implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
[staticPool setAge:18];
[staticPool setName:@"Clement"];
UIButton *btn = [[UIButton alloc]initWithFrame:CGRectMake(50, 100, 200, 50)];
[btn setTitle:@"跳转到获取页面" forState:UIControlStateNormal];
[btn setTitleColor:[UIColor orangeColor] forState:UIControlStateNormal];
[btn addTarget:self action:@selector(click) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:btn];
}
-(void)click
{
PageBViewController *page = [[PageBViewController alloc]init];
[self presentViewController:page animated:YES completion:nil];
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
@end
最后在另一个页面获取
#import "PageBViewController.h"
#import "staticPool.h"
@interface PageBViewController ()
@end
@implementation PageBViewController
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view.
self.view.backgroundColor = [UIColor whiteColor];
UILabel *name = [[UILabel alloc]initWithFrame:CGRectMake(50, 100, 200, 35)];
UILabel *age = [[UILabel alloc]initWithFrame:CGRectMake(50, 200, 200, 35)];
name.textColor = [UIColor orangeColor];
age.textColor = [UIColor orangeColor];
[self.view addSubview:name];
[self.view addSubview:age];
NSString *theName = [staticPool getName];
NSInteger theAge = [staticPool getAge];
name.text = theName;
age.text = [NSString stringWithFormat:@"%d",theAge];
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
