Question

我有一点问题。我正在对我编写的iOS程序进行一些更改，但我遇到了一个问题。我不断得到一个“预期'{'之前'''令牌”警告，但我的编码技能不足以找到问题。一点帮助将非常感激。

#import "Search.h"
#import "RootViewController.h"

    //button
    - (IBAction)buttonPressed)sender{
    RootViewController *newview = [[RootViewController alloc] initWithNibName:@"RootViewController" bundle:nil];
    [UIView beginAnimations:nil context:NULL]; 
    [UIView setAnimationDuration:0.5]; 
    [UIView setAnimationTransition:UIViewAnimationTransitionFl ipFromRight forView:self.view cache:YES]; 
    [self.view addSubview:newview.view]; 
    [UIView commitAnimations];

    @implementation Search
@end

Answer 1

正确的语法是

#import "Search.h"
#import "RootViewController.h"


  @implementation Search
//button
 - (IBAction)buttonPressed:(id)sender {
        RootViewController *newview = [[RootViewController alloc]  initWithNibName:@"RootViewController" bundle:nil];
        [UIView beginAnimations:nil context:NULL]; 
        [UIView setAnimationDuration:0.5]; 
        [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:self.view cache:YES]; 
        [self.view addSubview:newview.view]; 
        [UIView commitAnimations];
    }

@end

Answer 2

您尚未完成代码块- (IBAction)buttonPressed)sender{。您需要在某处使用结束括号（}）来告诉代码buttonPressed方法结束的位置。

Answer 3

- (IBAction)buttonPressed)sender{

应该是

- (IBAction)buttonPressed:(id)sender{

你需要一个}之后

[UIView commitAnimations];

像：

[UIView commitAnimations];

}

常量预期“{”在“）”之前
