linkmap中存放的是app可执行文件Mach-O格式组织的各类数据的清单，根据LinkMap展开对Mach-O文件及dyld加载Mach-O可执行文件的细节
Mach-O文件解析
这部分着重对Mach-O分析工具及分析进行注解
Mach-O文件分析工具：
-
XCode自带的/usr/bin/pagestuff , lipo , file , otool , nm
-
jtool
命令行中用man命令可以分别查询到上述各工具的作用，比如可以按逻辑页数查看Mach-O文件(比如app名字为name)内容的pagestuff命令pagestuff name.app/name {pagenum} //如果pagenum为0，输出一般是:File Page 0 contains Mach-O headers pagestuff name.app/name -a //会把所有页中内容信息全部输出
由一个Demo工程展开对Mach-O文件的分析
Xcode 8.3创建一个Single View Application, 不修改AppDelegate及ViewController类，新增SampleObject类并修改main.m
代码如下：
//ViewController.m
#import "ViewController.h"
@interface ViewController ()
@end
@implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
//SampleObject.h
#import <Foundation/Foundation.h>
@interface SampleObject : NSObject
@property (nonatomic,strong) NSObject* propertyObj;
- (void)getSomeResultWithString:(NSString*)inputString number:(NSNumber*)number;
@end
//SampleObject.mm
#import "SampleObject.h"
#import <stdio.h>
const NSString* cntstr = @"SampleObjectKey";
@interface SampleObject()
@property (nonatomic,strong) NSString* sampleName;
@property (nonatomic,assign) NSUInteger sampleId;
@end
@implementation SampleObject
- (void)getSomeResultWithString:(NSString*)inputString number:(NSNumber*)number
{
NSString* currentStr = [NSString stringWithFormat:@"%@:%@",inputString,number];
NSUInteger stackNum = 123;
__block NSString* blockString = nil;
dispatch_async(dispatch_get_main_queue(), ^{
NSString* compositedString = [NSString stringWithFormat:@"%@:%@:%lul",cntstr,currentStr,stackNum];
NSLog(@"composite string:%@,succeeded",compositedString);
puts(compositedString.UTF8String);
blockString = compositedString;
});
}
//main.m
#import <UIKit/UIKit.h>
#import "AppDelegate.h"
#import "SampleObject.h"
int main(int argc, char * argv[]) {
@autoreleasepool {
SampleObject* obj = [SampleObject new];
obj.propertyObj = [NSObject new];
[obj getSomeResultWithString:@"ab" number:@2];
return UIApplicationMain(argc, argv, nil, NSStringFromClass([AppDelegate class]));
}
}
@end
Mach-O文件格式
所得LinkMap文件输出如下：

关于Mach-O文件被dyld加载进内存涉及的数据结构，可以参考mach-o/loader.h中mach_header , segment_command的注释
对整个dyld加载及linkmap中各段涵义的解释会在篇二中进行
