iphone - UItextView 的 NSUnknownKeyException

Question

我的代码：

@interface UITextView ()
- (id)styleString; // make compiler happy
@end

@interface MBTextView : UITextView

@end


#import "MBTextView.h"

@implementation MBTextView
- (id)styleString {
    return [[super styleString] stringByAppendingString:@"; line-height: 1.2em"];
}
@end

我打电话给：

[MBTextView setValue:@"<b>big</b><br>blah blah" forKey:@"contentToHTMLString"];

它给了我 NSUnknownKeyException。但如果我只使用：

[UItextView setValue:@"<b>big</b><br>blah blah" forKey:@"contentToHTMLString"]; all is ok.what wrong with my code?

Answer 1

对不起，这是我的错误：

[UItextView.text setValue:@"<b>big</b><br>blah blah" forKey:@"contentToHTMLString"]; 

我不能使用文字，对不起
