[英]Create a UIbutton and UIImageview in UITextView
我的屏幕上有一个UITextview,我在屏幕上的拖放操作中创建了textview,现在我想在textview的最后(文本视图中的文本结尾)添加按钮,然后该怎么做?
我一直在尝试
[super viewDidLoad];
SelectInvestiList = [[NSMutableArray alloc] initWithCapacity:[InvestiList count]];
AppDelegate *appDeleg = (AppDelegate *)[[UIApplication sharedApplication]delegate];
textViewInvest.text=nil;
UIButton*button=[UIButton buttonWithType:UIButtonTypeRoundedRect];
[button setFrame:CGRectMake(0, 0, 30, 30)];
[button setTitle:@"test" forState:UIControlStateNormal];
[textViewInvest addSubview:button];
NSMutableString *prev=[[NSMutableString alloc] init];
if (appDeleg.chiefCompText != nil) {
prev=(NSMutableString *) textViewInvest.text;
[prev appendString:(NSMutableString *) appDeleg.chiefCompText];
textViewInvest.text=[prev capitalizedString];
}
if (appDeleg.vitalText != nil) {
prev=(NSMutableString *)textViewInvest.text;
[prev appendString:(NSMutableString *) appDeleg.vitalText];
textViewInvest.text=[prev capitalizedString];
}
但这不起作用..
UIButton *btn = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[btn setFrame:CGRectMake(0, 0, 10, 20)];
[btn setTitle:@"Ram" forState:UIControlStateNormal];
//[self.view addSubview:btn];
[textview addSubview:btn];
set the button frame according to your text in textview.
我不确定您是否正在使用“界面构建器”。
你可以试试看
UIButton *myButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
myButton.frame = CGRectMake(0.0, 100.0, 50.0, 30.0);
[yourTextView addSubview:myButton];
我猜您在通过代码添加时应该提到按钮的type
。 我只是用它来工作:
UIButton*button=[UIButton buttonWithType:UIButtonTypeRoundedRect];
[button setFrame:CGRectMake(0, 0, 30, 30)];
[button setTitle:@"test" forState:UIControlStateNormal];
[yourTextView addSubview:button];
看看吧,亲爱的,它总是对我有用。
for (id view in [textView subviews]) {
if ([view isKindOfClass:[UIScrollView class]]) {
UIButton *btn = [[UIButton alloc] initWithFrame:CGRectMake(0,0,100,35)];
[view addSubview:btn];
}
}
试试这个代码。 在这里我也创建textview。 这对我来说很好。
UITextView *yourTextView = [[UITextView alloc] initWithFrame:CGRectMake(0.0, 0.0, 320.0, 400.0)];
yourTextView.backgroundColor = [UIColor grayColor];
[self.view addSubview:yourTextView];
UIButton *myButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
myButton.frame = CGRectMake(0.0, 100.0, 50.0, 30.0);
[myButton setTitle:@"GO" forState:UIControlStateNormal];
[yourTextView addSubview:myButton];
它会工作。
for (id view in [textView subviews]) {
if ([view isKindOfClass:[UIScrollView class]]) {
UIButton *btn = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[btn setFrame:CGRectMake(0, 0, 10, 20)];
[btn setTitle:@"Ram" forState:UIControlStateNormal];
[view addSubview:btn];
}
}
