我只是想将两个 UIButton
和一个 UILabel
添加到我创建的 UIView 的子类中。这是那个子类:
InvitedView.m
#import "InvitedView.h"
#import "AppDelegate.h"
@class ViewController;
@interface InvitedView() {
UIButton *accept;
UIButton *decline;
UILabel *question;
UIView *gray;
ViewController *myViewController;
NSString *holduser;
}
@end
@implementation InvitedView
- (id)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if (self) {
gray = [[UIView alloc] initWithFrame:frame];
if(![(AppDelegate*)[[UIApplication sharedApplication] delegate] invitedby]) {
//
}
else {
holduser = [[NSString alloc] initWithString:[(AppDelegate*)[[UIApplication sharedApplication] delegate] getInvitedBy]];
}
question = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, frame.size.width, frame.size.height / 2)];
accept = [[UIButton alloc] initWithFrame:CGRectMake(0, frame.size.height / 2, frame.size.width / 2, frame.size.height / 2)];
decline = [[UIButton alloc] initWithFrame:CGRectMake(frame.size.width / 2, frame.size.height / 2, frame.size.width / 2, frame.size.height / 2)];
accept.backgroundColor = [UIColor redColor];
decline.backgroundColor = [UIColor greenColor];
question.backgroundColor = [UIColor blueColor];
[question setFont:[UIFont fontWithName:@"HelveticaNeue-Bold" size:10.0]];
[decline.titleLabel setFont:[UIFont fontWithName:@"HelveticaNeue-Bold" size:10.0]];
[accept.titleLabel setFont:[UIFont fontWithName:@"HelveticaNeue-Bold" size:10.0]];
[accept.titleLabel setText:@"ACCEPT"];
[accept.titleLabel setTextColor:[UIColor colorWithRed:211.0f/255.0f green:243.0f/255.0f blue:219.0f/255.0f alpha:1.0f]];
//accept.layer.borderWidth = 2;
//accept.layer.borderColor = (__bridge CGColorRef _Nullable)([UIColor colorWithRed:211.0f/255.0f green:243.0f/255.0f blue:219.0f/255.0f alpha:1.0f]);
[decline.titleLabel setText:@"DECLINE"];
[decline.titleLabel setFont:[UIFont fontWithName:@"HelveticaNeue-Bold" size:16.0]];
[decline.titleLabel setTextColor:[UIColor colorWithRed:211.0f/255.0f green:243.0f/255.0f blue:219.0f/255.0f alpha:1.0f]];
//decline.layer.borderColor = (__bridge CGColorRef _Nullable)([UIColor colorWithRed:211.0f/255.0f green:243.0f/255.0f blue:219.0f/255.0f alpha:1.0f]);
//decline.layer.borderWidth = 2;
NSLog(@"holduser way down ********: %@", holduser);
[question setText:[[NSString alloc] initWithFormat:@"You have been invited to a group game by %@", holduser]];
question.numberOfLines = 0;
question.textAlignment = NSTextAlignmentCenter;
[question setTextColor:[UIColor colorWithRed:211.0f/255.0f green:243.0f/255.0f blue:219.0f/255.0f alpha:1.0f]];
[question setFont:[UIFont fontWithName:@"HelveticaNeue-Bold" size:14.0]];
[accept addTarget:myViewController action:@selector(acceptInvite) forControlEvents:UIControlEventTouchUpInside];
[decline addTarget:myViewController action:@selector(declineInvite) forControlEvents:UIControlEventTouchUpInside];
[gray addSubview:accept];
[gray addSubview:decline];
[gray addSubview:question];
[self addSubview:gray];
}
return self;
}
@end
在我的 View Controller 中,我添加了一个 InvitedView
实例:
invitedView = [[InvitedView alloc] initWithFrame:CGRectMake(50, 244, 220, 120)];
我使用 [invitedView setHidden:YES]
将实例设置为隐藏。
在后面的流程中,我的应用调用了一个方法来更改 InvitedView
实例的 setHidden
值,如下所示:
- (void)doSomethingWithTheNewValueOfFlagForHid {
dispatch_async(dispatch_get_main_queue(), ^(void){
[invitedView setHidden:NO];
});
}
上图是输出。如您所见,按钮和标签不在框内,尽管我将它们相对放置在 InsideView.m
内。有任何想法吗?谢谢。
更新
InvitedView.m 中的实现 block 现在如下所示:
@implementation InvitedView
-(void)drawRect:(CGRect)frame {
question = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, frame.size.width, frame.size.height / 2)];
accept = [[UIButton alloc] initWithFrame:CGRectMake(0, frame.size.height / 2, frame.size.width / 2, frame.size.height / 2)];
decline = [[UIButton alloc] initWithFrame:CGRectMake(frame.size.width / 2, frame.size.height / 2, frame.size.width / 2, frame.size.height / 2)];
accept.backgroundColor = [UIColor redColor];
decline.backgroundColor = [UIColor greenColor];
question.backgroundColor = [UIColor blueColor];
[question setFont:[UIFont fontWithName:@"HelveticaNeue-Bold" size:10.0]];
[decline.titleLabel setFont:[UIFont fontWithName:@"HelveticaNeue-Bold" size:10.0]];
[accept.titleLabel setFont:[UIFont fontWithName:@"HelveticaNeue-Bold" size:10.0]];
[accept.titleLabel setText:@"ACCEPT"];
[accept.titleLabel setTextColor:[UIColor colorWithRed:211.0f/255.0f green:243.0f/255.0f blue:219.0f/255.0f alpha:1.0f]];
//accept.layer.borderWidth = 2;
//accept.layer.borderColor = (__bridge CGColorRef _Nullable)([UIColor colorWithRed:211.0f/255.0f green:243.0f/255.0f blue:219.0f/255.0f alpha:1.0f]);
[decline.titleLabel setText:@"DECLINE"];
[decline.titleLabel setFont:[UIFont fontWithName:@"HelveticaNeue-Bold" size:16.0]];
[decline.titleLabel setTextColor:[UIColor colorWithRed:211.0f/255.0f green:243.0f/255.0f blue:219.0f/255.0f alpha:1.0f]];
//decline.layer.borderColor = (__bridge CGColorRef _Nullable)([UIColor colorWithRed:211.0f/255.0f green:243.0f/255.0f blue:219.0f/255.0f alpha:1.0f]);
//decline.layer.borderWidth = 2;
NSLog(@"holduser way down ********: %@", holduser);
[question setText:[[NSString alloc] initWithFormat:@"You have been invited to a group game by %@", holduser]];
question.numberOfLines = 0;
question.textAlignment = NSTextAlignmentCenter;
[question setTextColor:[UIColor colorWithRed:211.0f/255.0f green:243.0f/255.0f blue:219.0f/255.0f alpha:1.0f]];
[question setFont:[UIFont fontWithName:@"HelveticaNeue-Bold" size:14.0]];
[accept addTarget:myViewController action:@selector(acceptInvite) forControlEvents:UIControlEventTouchUpInside];
[decline addTarget:myViewController action:@selector(declineInvite) forControlEvents:UIControlEventTouchUpInside];
[gray addSubview:accept];
[gray addSubview:decline];
[gray addSubview:question];
}
- (id)initWithFrame:(CGRect)frame
{
if(![(AppDelegate*)[[UIApplication sharedApplication] delegate] invitedby]) {
//
}
else {
holduser = [[NSString alloc] initWithString:[(AppDelegate*)[[UIApplication sharedApplication] delegate] getInvitedBy]];
}
self = [super initWithFrame:frame];
if (self) {
gray = [[UIView alloc] initWithFrame:frame];
[self addSubview:gray];
}
return self;
}
@end
最佳答案
在 initWithFrame:
的 if block 中写入上面的代码,而不是将其写入
-(void)drawRect:(CGRect)frame{
// Draw your custom view inside this method.
}
