IOS开发-OC页面跳转传递参数

蒋春敏 發表於 2023-7-19 11:21:00

<h2>使用OC进行IOS开发页面跳转传递参数的思路:</h2>
1.在AppDelegate.h中定义一个可变词典
2.在AppDelegate.m中初始化该可变词典
3.向字典中添加要传递的参数
4.在目标页面拿到参数
 
<h2>1.在AppDelegate.h中定义一个可变词典</h2>
<div class="cnblogs_code">
<pre>#import <UIKit/UIKit.h>

@interface AppDelegate : UIResponder <UIApplicationDelegate>
@property (strong,nonatomic)UIWindow *window;
@property (strong, nonatomic) NSMutableDictionary *RouterData;//路由参数字典

@end</pre>
</div>
 
<h2>2.在AppDelegate.m中初始化该可变词典</h2>
<div class="cnblogs_code">
<pre>//
//AppDelegate.m
//viewtest
//
//Created by 001 on 2023/5/9.
//
#define WYColor(r, g, b)
#import "AppDelegate.h"
#import "datashare1.h"
@interface AppDelegate ()

@end

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
_RouterData = [ initWithCapacity:1];

datashare1 *sharview = [ init];
UINavigationController *navigation = [ initWithRootViewController:sharview];
self.window.rootViewController = navigation;
;
NSLog(@"执行了");
return YES;
}

#pragma mark - UISceneSession lifecycle

@end</pre>
</div>
<h2>3.在源页面向字典中添加要传递的参数</h2>
<div class="cnblogs_code">

@implementation datashare1
-(void)goShare2{
AppDelegate *delegate = (AppDelegate *)[ delegate];
[delegate.RouterData setObject:@"我是datashare1传递的参数"forKey:@"data"];
datashare2 *shareview = [ init];

}
- (void)viewDidLoad {

UIButton *btn = ;
;
btn.frame = CGRectMake((self.view.frame.size.width-200)/2, (self.view.frame.size.height-100)/2, 200, 100);
;
self.view.backgroundColor = ;
;

}

/*
