Error reporting and resolution of #selector above swift5

Error reporting and resolution of #selector above swift5

The version of swift has changed a lot recently. If you add an event to a button, you must be very skilled in OC. How do you define functions and pass parameters in
swift

 let btn = UIButton()
 btn.tag = 2
 btn.addTarget(self, action: #selector(buttonClick(button:)), for: .touchUpInside)

  @objc func buttonClick(button: UIButton) {
       button.isSelected = true
       print(btn.tag!)
        print("\(btn.tag)")
 }

The custom method must be preceded by @ objc to follow the OC mechanism, otherwise an error will be reported

Xcode12.5 package framework error [How to Solve]

1. General

Today, Xcode was upgraded to 12.5.1. When compiling the existing project, the problem of swift incompatibility reported by referring to the framework compiled by swift appeared again. According to previous experience, just pack it again with the latest version of Xcode, but my colleague recommended a configuration to avoid the problem of swift incompatibility in the later stage, but this configuration was set, But it triggered a series of changes.

2. Project configuration and script modification

2.1. Modify the build libraries for distribution configuration item

This upgrade will ‘build settings’ – & gt` Build Options`->` Build libraries for distribution ` is set to yes, which has solved the problem of incompatibility in the later stage (it is set temporarily and needs to be verified in the later stage).

two point two   Modify project build system

Because ‘build libraries for distribution’ is set to yes, ‘project settings’ – & gt; under’ file ‘in the Project menu` Build system needs to be changed from ‘legacy build system’ to ‘new build system (default)’. Otherwise, packaging will fail with the following error.

  two point three   Modify the universal aggregate script file

Our project uses a universalaggregate script file to execute the other two script files. One is xxxxkitaggregate of IOS_ IOS, one is xxxxkitaggregate of tvos_ tvOS。 In the universalaggregate script, add ` – usemodernbuildsystem = no ‘after the two instructions respectively. If it is set to no, it means that the build system adopts’ legacy build system’, and if it is set to yes, it adopts’ new build system (default) ‘. As follows:

xcodebuild -target "XXXXKitAggregate_iOS" BUILD_DIR="${BUILD_DIR}" -UseModernBuildSystem=NO
xcodebuild -target "XXXXKitAggregate_tvOS" BUILD_DIR="${BUILD_DIR}" -UseModernBuildSystem=NO

Add ` – usemodernbuildsystem = no ‘to avoid disk read-write errors caused by simultaneous packaging of IOS and tvos
the error is as follows:

--error: error: accessing build database "xxx/build/XCBuildData/build.db": disk I/O error

Or:

accessing build database "/Users/xxxx/Work/Git/NLDFramework/XXXToolKit/build/XCBuildData/build.db": database is locked Possibly there are two concurrent builds running in the same filesystem location.

2.4 modify the packaging script (xxxxkitaggregate_ios, xxxxkitaggregate_tvos)

Add ‘RM – RF ${build_dir}’ before the ‘xcodebuild – target “XXXX’ command, and remove ‘clean’ from the ‘xcodebuild’ command, as shown in the following figure:

Before each build, delete the build file directory to avoid the following errors:

Could not delete `/Users/xxxx/Work/Git/NLDFramework/XXXMenuKit/build` because it was not created by the build system.

2.5 modify the configuration in Jenkins project

If the framework is packaged through Jenkins, you need to find the build configuration under the corresponding project configuration in Jenkins and check ‘allow failing build results’. Otherwise, Jenkins packaging will fail due to disk read-write exceptions. Check it, that is, ignore the exceptions and put the packaged framework in the specified location.

If not checked, Jenkins’s final output results are as follows:

When checked, Jenkins’s final output results are as follows:

ERROR ITMS-90022: “Missing required icon file. [How to Solve]

1. Problem

ERROR ITMS-90022: “Missing required icon file. The bundle does not contain an app icon for iPhone/iPod Touch of exactly ‘120×120’ pixels, in .png format for iOS versions >= 10.0. To support older versions of iOS, the icon may be required in the bundle outside of an asset catalog. Make sure the Info.plist file includes appropriate entries referencing the file. See https://developer.apple.com/documentation/bundleresources/information_property_list/user_interface”


2. Solution: Just make sure there are 120×120 icons in the AppIcon

How to Solve pod Error: “Authentication token is invalid or unverified. Either verify it with the email that…”

The following error occurs when executing pod trunk push:

[!] Authentication token is invalid or unverified. Either verify it with the email that was sent or register a new session.

Solution:

1. Execute the command: pod trunk register ‘your mailbox’, ‘XXXXXX’ — description =’xxxx ‘   Re register your account
2. Find and open the verification link in your email
3. Return to the terminal and execute the command again: pod trunk push xxxxx.podspec — allow warnings

Sending ‘const NSString *’ to parameter of type ‘NSString *’ discards qualifiers [Solved] 

For example, write const NSString* firstString = @"xxx";
NSString* secondString = @"yyyy";
[secondString isEqualToString:firstString];
There is a warning about sending 'const NSString *' to parameter of type 'NSString *' discards qualifiers.
Workaround.
Change const NSString* firstString = @"xxx";
to NSString* const firstString = @"xxx";

Explanation: The former is equivalent to the pointer itself is not modifiable, the latter indicates that the content pointed to by the pointer is not modifiable, both serve to make firstString readable and unwritable only.

 

Sending ‘const NSString *__strong‘ to parameter of type ‘NSString *‘ discards qualifiers

String value encountered a warning message, record it

Sending 'const NSString *__strong' to parameter of type 'NSString *' discards qualifiers

The code is written like this

UIKIT_EXTERN const NSString * kNetworkType;

This warning will be issued when using it, and it will be changed to:

UIKIT_EXTERN NSString * const kNetworkType;

If const is placed after nsstring *, there will be no warning.
