ios 3.1.3 having problems with button titles?

[pacoo2454]

hello. ive been working on an app and up until now ive only been able to test it on ios 4+. i just recently gained access to a device running on 3.1.3 to test on as well and for some reason the titles for some buttons i have arent displaying, the buttons themselves are showing up but until i tap the screen, anywhere, they finally show up. has anyone else experienced this? as far as i can tell all of the code ive been using so far should be compatible from 3.0+

some extra info, the original device used for testing is an iphone 4 with 4.3 beta 3 installed and it works fine.

ive tested it on an iphone 3g with 4.2.1 installed and it worked fine.

the problem device is an iphone 3g with 3.1.3 installed.

this is how im setting up the buttons

UIButton *button1 = [UIButton buttonWithType:UIButtonTypeRoundedRect];
	button1.frame = CGRectMake(20.0, 10.0, 125.0, 37.0);
	[button1 addTarget:self action:@selector(button1Pressed) forControlEvents:UIControlEventTouchUpInside];
	[button1 setTitle:@"Clear" forState:UIControlStateNormal];
	[self addSubview:button1];

I have an app that sets button titles and your code looks good. By any chance is your method not getting called? Try putting in a few NSLogs to see what is/isn't getting called. Also if it is getting called when you touch anywhere on the screen, maybe it has something to do with a touchesbegan/ended method.

thanks for the quick reply.
i went ahead and added NSlogs before and after the line that sets the title and they are both displayed in the console when it is supposed to be. anyways, the buttons themselves are showing up, when the app first launches the buttons show up as empty boxes, then as soon as i interact with the app in anyway(touch the buttons in question, tap an empty area of the screen, tap a textfield) the titles are showing up. as of now im not implementing touchesBegan anywhere in my app.
any other ideas?

You're probably using a font that is available in iOS 4 but not in the earlier version.

well, as of now i havent even set any fonts up, so the default is just being used. but i went ahead and added this

button1.titleLabel.font = [UIFont systemFontOfSize:12];

and its still producing the same results.

also, the text eventually appears, so it can display the font, its just not displaying the text when the button is initially displayed on the screen.

alright, i got it to work correctly but it seems a bit absurd.

i had to change it from this

UIButton *button1 = [UIButton buttonWithType:UIButtonTypeRoundedRect];
	button1.frame = CGRectMake(20.0, 10.0, 125.0, 37.0);
	[button1 addTarget:self action:@selector(button1Pressed) forControlEvents:UIControlEventTouchUpInside];
	[button1 setTitle:@"Clear" forState:UIControlStateNormal]; <<<
	[self addSubview:button1];

to

UIButton *button1 = [UIButton buttonWithType:UIButtonTypeRoundedRect];
	button1.frame = CGRectMake(20.0, 10.0, 125.0, 37.0);
	[button1 setTitle:@"Clear" forState:UIControlStateNormal]; <<<
	button1.titleLabel.font = [UIFont systemFontOfSize:12];
	[button1 addTarget:self action:@selector(button1Pressed) forControlEvents:UIControlEventTouchUpInside];
	[self addSubview:button1];

thanks for everyone's input. =D

Sorry - I misread the original post when I mentioned the fonts. Glad it's working now.

actually, if you wouldnt have posted that id probably still be stuck. after moving that one line, i decided to remove the line setting the font, seeing as how i just wanted to use the default and it disappeared again! very weird.
thanks a lot =D
