Displaying an alert view similar to UIAlertView - ios

Question

I am trying to create a custom "alert view", nothing too fancy I just want to display a view overtop of the current view just like a UIAlertView.
Now here is the problem...I made the view in a nib file and now I want to alloc/init the view whenever I need to present an alert.Can anyone help me?
This is my attempt to get the view initialized...as of right now this crashes my app when I alloc/init a new alert view.
The app is crashing by telling me the view is not key-value compliant for the outlets.. I definitely have the outlets hooked up properly, unless I have a "File's Owner" thing screwed up.
NSObject 0x14e49800> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key....
- (id)initWithCoder:(NSCoder *)aDecoder {
self = [super initWithCoder:aDecoder];
if (self) {
[self load];
}
return self;
}
- (void)load {
NSArray *views = [[NSBundle mainBundle] loadNibNamed:NSStringFromClass([self class]) owner:nil options:nil];
[self addSubview:[views firstObject]];
}
- (void)awakeFromNib {
[super awakeFromNib];
}
- (id)initWithFrame:(CGRect)frame
{
self = [[NSBundle mainBundle] loadNibNamed:NSStringFromClass([self class]) owner:nil options:nil][0];
if (self) {
[self addSubview:self.contentView];
self.frame = frame;
}
return self;
}
- (instancetype)initWithTitle:(NSString *)title
message:(NSString *)message
delegate:(id)delegate
cancelButtonTitle:(NSString *)cancelButtonTitle
confirmButtonTitle:(NSString *)confirmButtonTitle {
self = [self initWithFrame:CGRectMake(0, 0, 320, 568)];
if (self) {
}
return self;
}
I made this method to present the view, just a simple addSubview...
- (void)showInView:(UIView *)view {
[view addSubview:self];
}

Try disabling autolayout and run the code.

Answer 2

Create a class same as below
#import "MyOverLay.h"
#interface MyOverLay (){
// control declarations
UIActivityIndicatorView *activitySpinner;
UILabel *loadingLabel;
}
#end
#implementation AcuOverLay
- (id)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if (self) {
}
return self;
}
- (void)show:(NSString *)message{
// configurable bits
self.backgroundColor = [UIColor blackColor];
self.alpha = 0.75f;
self.autoresizingMask =UIViewAutoresizingFlexibleHeight;
float labelHeight = 22;
float labelWidth = self.frame.size.width - 20;
// derive the center x and y
float centerX = self.frame.size.width / 2;
float centerY = self.frame.size.height / 2;
// create the activity spinner, center it horizontall and put it 5 points above center x
activitySpinner = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge];
activitySpinner.frame = CGRectMake(centerX - (activitySpinner.frame.size.width / 2) , centerY - activitySpinner.frame.size.height - 20, activitySpinner.frame.size.width, activitySpinner.frame.size.height);
activitySpinner.autoresizingMask = UIViewAutoresizingFlexibleHeight;
[self addSubview:activitySpinner];
[activitySpinner startAnimating];
// create and configure the "Loading Data" label
loadingLabel = [[UILabel alloc]initWithFrame:CGRectMake(centerX - (labelWidth / 2), centerY + 20 , labelWidth, labelHeight)];
loadingLabel.backgroundColor = [UIColor clearColor];
loadingLabel.textColor = [UIColor whiteColor];
loadingLabel.text = message;
loadingLabel.textAlignment = NSTextAlignmentCenter;
loadingLabel.autoresizingMask = UIViewAutoresizingFlexibleHeight;
[self addSubview:loadingLabel];
}
- (void)hide{
[UIView animateWithDuration:0.5 animations:^{
self.alpha = 0;
[self removeFromSuperview];
}];
}
#end
then create instance wherever you want
loadingOverlay = [[MyOverLay alloc]initWithFrame:[UIScreen mainScreen].bounds];
loadingOverlay.tag = 999;
[[[UIApplication sharedApplication] keyWindow] addSubview:loadingOverlay];
[loadingOverlay show:#"Saving ..."];
