我只是添加了一个带有按钮的快速介绍屏幕,可以正确编译和显示,但我的按钮没有响应Objective c 代码中添加的UIButton不响应触摸,objective-c,ios,Objective C,Ios,我只是添加了一个带有按钮的快速介绍屏幕,可以正确编译和显示,但我的按钮没有响应 - (void)viewDidLoad { [super viewDidLoad]; NSLog(@"viewDidLoad!"); [self showIntro]; } // make a quick Intro screen - (void) showIntro { UIImageView *myBackImage = [[UIImageView alloc] initWithFra
- (void)viewDidLoad {
[super viewDidLoad];
NSLog(@"viewDidLoad!");

// make a quick Intro screen
- (void) showIntro {
UIImageView *myBackImage = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 320, 460)];
[myBackImage setImage:(UIImage *) [UIImage imageNamed:@"myBkgnd.png"]];
UIButton *clickBtn = [UIButton buttonWithType:UIButtonTypeCustom ];
[clickBtn addTarget:self action:@selector(myButton_pressed:) forControlEvents:UIControlEventTouchUpInside];
[clickBtn setImage:(UIImage *) [UIImage imageNamed:@"btnImage.png"] forState:UIControlStateNormal];
clickBtn.frame = CGRectMake(111, 200, 75, 60);
[myBackImage addSubview:clickBtn];

- (void)myButton_pressed:(UIButton*)button {
NSLog(@"Button Pressed!");
}
我忽略了什么?
谢谢 您在
UIImageView
中添加了ui按钮
,但您没有忘记imageView的
用户交互
,因为默认无
。因此:
myBackImage.userInteractionEnabled = YES;
编辑:刚格式化尝试对UIButton使用initWithFrame构造函数,而不是buttonWithType。
