[英]Create a UIbutton and UIImageview in UITextView
我的屏幕上有一個UITextview,我在屏幕上的拖放操作中創建了textview,現在我想在textview的最后(文本視圖中的文本結尾)添加按鈕,然后該怎么做?
我一直在嘗試
[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];
}
但這不起作用..
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.
我不確定您是否正在使用“界面構建器”。
你可以試試看
UIButton *myButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
myButton.frame = CGRectMake(0.0, 100.0, 50.0, 30.0);
[yourTextView addSubview:myButton];
我猜您在通過代碼添加時應該提到按鈕的type
。 我只是用它來工作:
UIButton*button=[UIButton buttonWithType:UIButtonTypeRoundedRect];
[button setFrame:CGRectMake(0, 0, 30, 30)];
[button setTitle:@"test" forState:UIControlStateNormal];
[yourTextView addSubview:button];
看看吧,親愛的,它總是對我有用。
for (id view in [textView subviews]) {
if ([view isKindOfClass:[UIScrollView class]]) {
UIButton *btn = [[UIButton alloc] initWithFrame:CGRectMake(0,0,100,35)];
[view addSubview:btn];
}
}
試試這個代碼。 在這里我也創建textview。 這對我來說很好。
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];
它會工作。
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];
}
}
