That code is correct. If that is the code that you are using, you should check whether it is being called. Try putting an NSLog("changing font");call right before it or something, so you can tell whether or not it is really happening.
该代码是正确的。如果这是您正在使用的代码，您应该检查它是否正在被调用。尝试NSLog("changing font");在它之前打个电话或其他什么，这样你就可以判断它是否真的发生了。
A few suggestions, though. There is probably a more descriptive name for your textview than textView3. Don't worry about your variable names being too verbose; believe me, it's a good thing. Also, if textView3 is an instance variable, you really shouldn't be accessing it directly. Use encapsulation by declaring it as a @propertyand then @synthesize-ing it. Then, your call might look like self.textViewThatDoesSomething.font = ….
不过有一些建议。您的 textview 可能有一个比 textView3 更具描述性的名称。不要担心你的变量名太冗长；相信我，这是一件好事。此外，如果 textView3 是一个实例变量，您真的不应该直接访问它。通过将其声明为 a@property然后使用封装来使用@synthesize它。然后，您的电话可能看起来像self.textViewThatDoesSomething.font = …。
Good luck!
祝你好运！
Update:I just had another idea. It may be that your textView3is not hooked up properly in Interface Builder. Check that and try again.
更新：我只是有另一个想法。可能是您textView3在 Interface Builder 中没有正确连接。检查并重试。

Use:
用：
textview.font = [UIFont fontWithName:@"Arial" size:FontSize];
Where FontSizeis an int.
哪里FontSize有int。
