動態庫載入過程

1，將framework引入工程中比如Dylib.framework

2，設定target--->Build Phases--->Link Binary with Libraries,新增framework

3，設定target--->Build Phases---->Copy Bindle Resource,

4，新增Copy Files,

如圖：

5，設定Build Settings---->Linking----->Runpath Search Paths---->@executable_path

6,程式碼部分：

在使用的地方引入#import <Dylib/Dylib.h>

- (IBAction)bundleLoadAction:(id)sender {

NSLog(@"bundleLoadAction");

//NSString *documentsPath = [NSString stringWithFormat:@"%@/Documents/Dylib.framework",NSHomeDirectory()];

NSString*documentsPath = [NSStringstringWithFormat:@"%@/Dylib.framework",[[NSBundlemainBundle]bundlePath]];

[selfbundleLoadDylibWithPath:documentsPath];

}

- (void)bundleLoadDylibWithPath:(NSString*)path

{

_libPath= path;

NSError*err =nil;

NSBundle*bundle = [NSBundlebundleWithPath:path];

if([bundleloadAndReturnError:&err]) {

NSLog(@"bundle load framework success.");

}else{

NSLog(@"bundle load framework err:%@",err);

}

}

- (IBAction)trigerAction:(id)sender {

NSLog(@"trigerAction");

ClassrootClass =NSClassFromString(@"Person");

if(rootClass) {

idobject = [[rootClassalloc]init];

[(Person*)objectrun];

}

}

三個函式可看到效果。
