Answer 1

I have manual solution for you. But I think its not a good solution:
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Added to Cart" message:#"Some items are added for time being!" delegate:self cancelButtonTitle:#"View Cart" otherButtonTitles:#"", nil];
UILabel *buttonTitle = [[UILabel alloc] initWithFrame:CGRectMake(148, 102, 125, 40)];
buttonTitle.text = #"Continue Shopping";
buttonTitle.font = [UIFont boldSystemFontOfSize:15];
buttonTitle.textColor = [UIColor whiteColor];
buttonTitle.textAlignment = UITextAlignmentCenter;
buttonTitle.backgroundColor = [UIColor clearColor];
buttonTitle.numberOfLines = 2;
[alert addSubview:buttonTitle];
alert.tag = 20;
[buttonTitle release];
[alert show];
You can use it anyway....

UIAlertView doesn't support multi-line buttons. One option would be to just use "Continue" instead of "Continue Shopping" as the button title, otherwise you'd have to use a custom alert view component, e.g. CODialog (you might have to customize it a bit to allow multi-line buttons, but it should be easy).

I think you can try to set numbersOfLine property to label on button. But i don`t know will apple aprove that.
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Added to Cart" message:#"Some items are added for time being!" delegate:self cancelButtonTitle:#"View Cart" otherButtonTitles:#"Continue \n Shopping", nil];
NSArray *subviewsArray = [alert subviews];
for (UIView *subview in subviewsArray) {
if ([subview isKindOfClass:[UIButton class]]) {
NSArray *btnSubviews = [subview subviews];
for (UIView *btnSubview in btnSubviews) {
if ([btnSubview isKindOfClass:[UILabel class]]) {
UILabel *title = (UILabel *)btnSubview;
title.numberOfLines = 2;
}
}
}
}
alert.tag = 20;
[alert show];
[alert release];

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Added to Cart" message:#"Some items are added for time being!" delegate:self cancelButtonTitle:#"View Cart" otherButtonTitles:#"Continue \n Shopping", nil];
alert.tag = 20;
[[[alert buttons] objectAtIndex:1] setLineBreakMode:UILineBreakModeWordWrap];
[alert show];
This code does exactly what you need.
Note, however that
- [UIAlertView buttons] is undocumented
- [UIButton setLineBreakMode] is deprecated. You can however, replace it with
[button.titleLabel setLineBreakMode] which is essentially the same.
