Because the original code use inheritance which is too intrusive, now I use category to reconstruct the code, and released new version 。

• For iOS8+:

use_frameworks!
target '<Your Target Name>' do
    pod 'UITextView+CMInputView'
end

• Drag all files under CMInputView/CMInputView/Class folder into your project.

Firstly, you need import the .h file.

if cocoaposd:

#import <UITextView+CMInputView.h>

if manually:

#import "UITextView+CMInputView.h"

Then create UITextView and use this category to configure .

    UITextView * inputView = [[UITextView alloc]initWithFrame:CGRectMake(0, 100, self.view.bounds.size.width, 55)];
    inputView.font = [UIFont systemFontOfSize:18];
    
    inputView.cm_placeholder =  @"UITextView+CMInputView";
    inputView.cm_placeholderColor = [UIColor redColor];
    inputView.cm_maxNumberOfLines = 3;
    
    [self.view addSubview:inputView];

If you want to make the UITextView break line automatically ,you can write like this:

    UITextView * inputView = [[UITextView alloc]initWithFrame:CGRectMake(0, 100, self.view.bounds.size.width, 55)];
    inputView.font = [UIFont systemFontOfSize:18];
   
    inputView.cm_placeholder =  @"UITextView+CMInputView";
    inputView.cm_placeholderColor = [UIColor redColor];
    inputView.cm_autoLineBreak = YES;
    
    [self.view addSubview:inputView];

Congratulations! You're done. 🎉

• The category do not support constrained layout,please use carefully !
• Once you set cm_maxNumberOfLines ,the effect always works,even if you set YES to cm_autoLineBreak
