为什么我的方法不能完全发挥作用？ （iPhone SDK）
我的代码中有一个方法：
-(IBAction) actionButtonPressed: (id) sender{
NSLog(@"%@",actionButton.titleLabel.text);
if (actionButton.titleLabel.text == @"Begin Recording"){
[actionButton setTitle:@"Finish Recording" forState:UIControlStateNormal];
[actionButton setTitle:@"Finish Recording" forState:UIControlStateApplication];
[actionButton setTitle:@"Finish Recording" forState:UIControlStateHighlighted];
[actionButton setTitle:@"Finish Recording" forState:UIControlStateReserved];
[actionButton setTitle:@"Finish Recording" forState:UIControlStateSelected];
[actionButton setTitle:@"Finish Recording" forState:UIControlStateDisabled];
UIImage *redButton = [UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"bigredbutton" ofType:@"png"]];
[actionButton setBackgroundImage:redButton forState:UIControlStateNormal];
[actionButton setBackgroundImage:redButton forState:UIControlStateApplication];
[actionButton setBackgroundImage:redButton forState:UIControlStateHighlighted];
[actionButton setBackgroundImage:redButton forState:UIControlStateReserved];
[actionButton setBackgroundImage:redButton forState:UIControlStateSelected];
[actionButton setBackgroundImage:redButton forState:UIControlStateDisabled];
}
if (actionButton.titleLabel.text == @"Finish Recording"){
[self dismissModalViewControllerAnimated:YES];
}
}
出于某种原因， NSLog 调用确实有效并显示在控制台上。该按钮一开始显示“开始录制”，但按下它不会执行任何操作，即使它与 Interface Builder 中的“Touch Up Inside”相关联以调用此方法并被引用。
I have a method here that is in my code:
-(IBAction) actionButtonPressed: (id) sender{
NSLog(@"%@",actionButton.titleLabel.text);
if (actionButton.titleLabel.text == @"Begin Recording"){
[actionButton setTitle:@"Finish Recording" forState:UIControlStateNormal];
[actionButton setTitle:@"Finish Recording" forState:UIControlStateApplication];
[actionButton setTitle:@"Finish Recording" forState:UIControlStateHighlighted];
[actionButton setTitle:@"Finish Recording" forState:UIControlStateReserved];
[actionButton setTitle:@"Finish Recording" forState:UIControlStateSelected];
[actionButton setTitle:@"Finish Recording" forState:UIControlStateDisabled];
UIImage *redButton = [UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"bigredbutton" ofType:@"png"]];
[actionButton setBackgroundImage:redButton forState:UIControlStateNormal];
[actionButton setBackgroundImage:redButton forState:UIControlStateApplication];
[actionButton setBackgroundImage:redButton forState:UIControlStateHighlighted];
[actionButton setBackgroundImage:redButton forState:UIControlStateReserved];
[actionButton setBackgroundImage:redButton forState:UIControlStateSelected];
[actionButton setBackgroundImage:redButton forState:UIControlStateDisabled];
}
if (actionButton.titleLabel.text == @"Finish Recording"){
[self dismissModalViewControllerAnimated:YES];
}
}
For some reason the NSLog call does work and shows up on the Console. The button starts out reading Begin Recording, yet pressing it does nothing even though it is tied up with Touch Up Inside in Interface Builder to call this method and is referenced.
