ios获取对象类名

[NSString stringWithUTF8String:object_getClassName(a)];

我们可以通过上述语句获取这个对象的所属类名。

例子:我们可以用到上述方法来获取keyBoard,改变keyBoard 的颜色,但是注意只有以下两种数字键盘才有效果:UIKeyboardTypeNumberPad,UIKeyboardTypePhonePad;

keyboardAppearance = UIKeyboardAppearanceAlert

- (void)textViewDidBeginEditing:(UITextView *)textView{

NSArray *ws = [[UIApplication sharedApplication] windows];

for(UIView *w in ws){

NSArray *vs = [w subviews];

for(UIView *v in vs){

if([[NSString stringWithUTF8String:object_getClassName(v)] isEqualToString:@”UIKeyboard”]){

v.backgroundColor = [UIColor redColor];

}

}

}
