If I am correct, you simply want to suppress the warnings.
如果我是对的，您只是想抑制警告。
#pragma GCC diagnostic ignored "-Wdeprecated-declarations"
This is simply to suppress the warnings. In release builds, you should not use any deprecated functions.
这只是为了抑制警告。在发布版本中，您不应使用任何已弃用的函数。
EDIT: To suppress specific code that invokes warnings, use :
编辑：要抑制调用警告的特定代码，请使用：
#pragma clang diagnostic push
#pragma clang diagnostic ignored "-Wdeprecated-declarations"
[self dismissModalViewControllerAnimated:YES];
#pragma clang diagnostic pop

@n00bProgrammer thanks for your answer.
@n00bProgrammer 感谢您的回答。
For those of us who still have code that supports earlier versions of iOS, the way I handle such old code is to wrap the older code in a version macro test as well as to suppress the compiler warnings that result.
对于那些仍然拥有支持较早版本 iOS 的代码的人，我处理这些旧代码的方法是将旧代码包装在版本宏测试中，并抑制由此产生的编译器警告。
Note that sometimes a deprecated item generates an implicit conversion warningthat needs to be suppressed using "-Wconversion".
请注意，有时不推荐使用的项目会生成隐式转换警告，需要使用“-Wconversion”来抑制该警告。
if (SYSTEM_VERSION_LESS_THAN(@"6.0")) {
#pragma clang diagnostic push
#pragma clang diagnostic ignored "-Wdeprecated-declarations"
#pragma clang diagnostic ignored "-Wconversion"
[controlCenter.label setLineBreakMode:UILineBreakModeWordWrap];
#pragma clang diagnostic pop
} else {
[controlCenter.label setLineBreakMode:NSLineBreakByWordWrapping];
}
You can find the version checker for older Objective-C code here: SYSTEM_VERSION_LESS_THAN()
您可以在此处找到旧版 Objective-C 代码的版本检查器：SYSTEM_VERSION_LESS_THAN()
You can find the version checker for new Swift and Objective-C code here: Swift and Objective-C version check past iOS 8
你可以在这里找到新的 Swift 和 Objective-C 代码的版本检查器：Swift and Objective-C version check through iOS 8

use thus the following code it works perfect
因此使用以下代码它完美无缺
[self dismissViewControllerAnimated:YES completion:nil];
[self dismissViewControllerAnimated:YES completion:nil];
Tested and working fine.
经测试，工作正常。
